    I REALLY want to understand taxonomies, but just can’t. Why wouldn’t you use tags?

    I’m sure this happened when tags came out, many people must have thought, “why not use categories?”

    Justin: Thank you. Now I’m intrigued, what would useful things be? The site itself is a crossover between a fansite (I find the term fansite offensive, because fansites are usually designed by people who don’t know coding, design in obsolete ways and steal everything they possibly could) and a news blog; and it never utilised categories and tags for anything other than news, everything else resides on pages; but I often end up interlinking those pages the old-fashioned way.

    I’m basically waiting for WP 2.8 to start developing the site’s next version (ever since I’ve seen the original tutorial on taxonomies) because of taxonomies AND clearning my documents’ head from unnecessary things some plugins appear to be generating and I’m always open to beta-testing interesting things once it’s happened. The lack of custom custonomies was the reason I never opened the gigography section to public and the reason two other sections are half-a$%ed.

    I guess I’ll jump to the forum.

    Justin this is a fantastic post. I can see a bunch of uses of this great feature. And I must agree with Andrea_R that this would be cool with a book-site. But why stop there, any kind of shop/review site could have great use of this. But what about a food- or estate-site? If only one could choose to cross-reference different taxonomies.

    Anyway, love the tutorial, can’t wait for WordPress 2.8…

    Justin, thanks for the detailed posts on taxonomies. Wonderful to have it all digested like this.

    Just recently I’ve come across the Pod plugin that provides a framework for creating custom content types and relationships between them.

    I know that this is different to custom taxonomies. Seeing that you have aquainted yourself with WP 2.8 already, my question is (if you are familiar with the concept of the Pod plugin) whether WordPress 2.8 has any new features that would bring something like custom content types closer to the ‘core’ just like the custom taxonomies.

    One of the most important things with content is the searcheability of said content so being able to create custom content types natively would mean the ability to use the native search functionality.

    (Kudos to the guys that created the Pod plugin though, it seriously redefines what you can do with Wordpress.)

    Very neat explanation, I wish I could find one earlier :( By the way, but what would you do if you want an actor or a director to have it’s own page, with more then just a photo and rich text description? Let’s say you want it to be as rich as your ordinary page, with user comments on it maybe, etc? Hmm… that’s an idea by the way, to add rich text editor to taxonomy description textarea!.. But what should one do with comments? Any straightforward way to bind them on taxonomy template?

    These plugins implement custom taxonomies in more intuitive way:

    Great post Justin!

    Your ideas and tutorials fit perfectly with what I’m trying to do at my site, but it expands the posibilities.

    Until now, I was creating a animation movies database similar to the one you’ve created. I made it based on pages and custom fields. You can see it here: http://www.protoones.com/film

    Now, I will replace custom fields with taxonomies for sure!!!

    Still, I have one question: I have created child pages with videos (trailers, clips, featurettes, …) for each movie. How would you create this “child pages” in your movie database?

    I’m not sure that a video should be a taxonomy. An actor or a director may appear in differente moviesm then we use taxonomies. But a video only belongs to one movie. Right? So, what we should use for videos?

    What do you think?

    But seriously this seems like 1/2 of the solution the other half being custom post types. That said, where did you add your ” image and short description of the (Tom Hanks)?” Seems like an “Actor” custom post type would be the perfect solution, no?

    Justin,

    I will take a look at the attachments solutions you mention. Even though I don’t think it will work for my website because most of the videos are not uploaded, they’re just embeded from YouTube, Vimeo, …

    On the other hand, I’ve been looking at your database and I have few more questions.

    What kind of object are your movies? Posts? Pages?

    If they are pages, I imagine you’ve created your own custom panels to add taxonomies to pages… Then, can you write another tutorial on how to do it? Or, even better, can you create a plugin “Taxonomy for ages”? ;)

    Lastly, for me, movies should be a taxonomy because if I write a post in the blog I should be able to tag movies, directors and studios in the same way using taxonomies. But if I made movies as taxonomies, I can not add actors and directors to movies, right?

    So, in your popcritics web, how will you link posts in the blog section with movies in the database?

    Thanks a lot!

    Justin, I just found your post via WP Topics and I’m interested in exploring this technique for my site, and indeed some future projects.

    A little while ago I was looking at how tags could be grouped and this seems to be the solution but I’m a little unclear as to whether using this techniques means negates the use of categories?

    For example, I use categories exclusively for geographic information e.g. Continent > Country

    I then use tags to describe the posts in terms of style of tents (e.g. yurts, tipis); activities (e.g. fishing, kayaking etc); setting (e.g. coastal, mountains, lakes etc) and so on…

    The problem is these are all lumped together whereas it would be better if they were grouped.

    If I use custom taxonomies, as you’ve described in your post, will I still be able to use categories for the geographical aspects?

    Using categories in this way on my site offers me the ability to easily manage them in the admin plus other advantages, also there’s the hierarchical aspect as later I’ll want to drill down to regions within countries as the site grows.

    @Dani asked ‘What kind of object are your movies? Posts? Pages?’

    I too am interested to know this but I am hoping they are categories ;-)

    Thank you Justin, much appreciated.

    Apart from your PopCritics’ treatment of custom taxonomies, do you know of any other sites out there that are implementing this feature?

    I can see this becoming more popular over time and at some point it would be neat to be able to filter and mix by taxonomies. A nice idea would be to create a search tags function much like on Delicious where you can select and unselect a selection of tags to sort results by.

    I find most blogs badly structured and see people use categories for ‘featured’ content, always a bad idea.

    Thanks again, Justin.

    Your Theme Hybrid Showcase is a good example for me as it mixes various taxonomies such as categories (theme), custom taxonomy (color), tags (tags)

    One thing I noticed is the URLs are not closed with a trailing slash. Is there a reason for that? I’ve been told it’s better to close URLs.

    Also, if I hack back to: http://themehybrid.com/showcase/color/ I get a 404, but I was hoping to see a page with a list of colours. Note: this is the same problem if I hack back to: http://themehybrid.com/showcase/tags/

    The breadcrumbs don’t mimic the URL, i.e. the label ‘color’ doesn’t precede the color.

    I see on PopCritics that you have set up pages to handle the tag clouds for each custom taxonomy, e.g. http://popcritics.com/movies/genres/

    But again, the breadcrumb system doesn’t contain a link to these custom taxonomy pages.

    Can your breadcrumb system, or any other system, be correctly set up to contain links to these custom taxonomy pages?

    Hi Justin,

    After you answered me that, in your database, movies are posts I thought it was not what fit my needs because I want to “tag” posts on the blog with the movies they talk about.

    Also, you build the database in a different site and you can not easily link blog posts and movies.

    So, for me, movies should be taxonomies. But, then, I can not “tag” movies with genre, actors, … right?

    To solve this issue I’ve found a solution: I create a movie as a post and as a term at the same time. Both have the same slug/name. Then I modify the taxonomy template page to include content form the post and the term.

    The code to include the post in the taxonomy looks like:

    What do you think? Any ideas to improve this solution?

    Hi – To use your movie database example, I’d like visitors to be able to view the Tom Hanks page, even if Tom Hanks is not in any movies. So it would show the term description as usual, but then a message saying ‘No movies for this actor’.

    I can successfully generate a list of all actors (including ones who are not in any movies yet) using the function get_terms() with ‘hide_empty’ set to zero, but I get a 404 error if I try to visit a term page that has not been associated with any posts (an actor in no movies).

    Justin; great posts … I’ve been reading through and have had good luck using taxonomies.

    Question though; can you either explain or show the code you used for the movie database, that allows you to pull the image from your posts (movie posters) and display all of them on to one page? Your explanation of how to add “Tom Hanks” information in the header area was alright, but there was no information about how to get all the images from separate posts into that archive/page.

    Because this post seems to be such an important resource for people making custom taxonomies, I thought I’d note here that I learned the filename format for template files for individual taxonomies (rather than a catch-all taxonomy.php template that affects director pages, actor pages, genre pages, etc.

    It’s taxonomy-slug.php; so, to use this post as an example, if you wanted your director template to be different from your other custom taxonomy templates, you’d just create a file called taxonomy-directors.php.

    Thanks Justin for this great post — of all the WordPress hacks I’ve learned, this is maybe the easiest to implement and also the most useful. It really stretches the boundaries of what WP is capable of.

    Another great tutorial… Thanks Justin!

    I’m using custom taxonomies for a site that has both a blog and a portfolio. There will be one category for text posts and one category for posts containing photos. I’d like to use custom taxonomies to classify the photo posts with additional data, and may occasionally have blog posts related to those classifications that would get tagged using the custom taxonomies as well. What I’m not sure of is how to do two things:

    1. Query posts that are under both one category and one taxonomy term
    2. Query posts that are under multiple taxonomy terms

    Any help would be greatly appreciated as I haven’t seen any info on this yet. Thanks again.

    I’m wondering, is it possible to intersect tags. For example if I am looking for movies that star Tom Hanks, AND are also action movies? Or Martin Scorsese films that are also Academy Award nominees (assuming the award nomination existed as a tag)?

    Being able to narrow on multiple tags simultaneously seems like a bigger advantage than simply grouping tags into sets (“taxonomies”). To select a tag and then generate a tag cloud for all items (and only those items) with that tag would really be cool.

    It’s unclear if that is possible, and if it is, whether this is part of it.

    @Jamie: I think that’s a great idea and one I’d like to see also. On one of my sites I will use categories for countries and custom taxonomies for: type of accommodation, style of accommodation, suitable for, activities etc.

    So, it would be great if my users, when viewing listings in Spain could drill down using the various taxononies e.g. villa, boutique, couples, swimming (as an example based on the array above)

    Sort of like filtering as used on Delicious.com, with a similar interface i.e. you enter the tags and search and to remove them click the [x]

    Great overview on how to use custom taxonomies in a real-world setting.

    My only issue is with duplicate content.

    Let’s use the Tom Hanks example. If I “tag” Tom Hanks with the taxnomies of “Actor” and “Producer”, wouldn’t that be almost considered duplicate content?

    eg. hxxp://example.com/actors/tom-hanks
    hxxp://example.com/producers/tom-hanks

    Wouldn’t it be better to have a “Tom Hanks” page/post (eg, hxxp://example.com/tom-hanks) where you use a custom page template to output the taxonomies he is associated with? Then use the canonical header tag to direct all the different “Tom Hanks” taxonomy pages to that page?

    I know this might be considered redundant considering the basic usage of taxonomies, but just a thought I had.

    A bit more in detail: I display the different taxonomies below the single-post (such as tags). That works fine. When I click on a term I only see my 404 page. It seems as if the template “taxonomy.php” (a copy of my archive.php without the conditional stuff) can not be detected or is not working at all.

    Is there any known issue in WP 2.8.3? Or what else could be a reason for this? Any ideas?

    To solve the 404 error issue, the trick is to call $wp_rewrite->flush_rules(); after registering the new taxonomies.

    Without doing this the rewrite rules won’t be updated, this means that if you are using pretty permalinks wordpress will never figure out that you are asking for a new taxonomy and will never work out what template to load – it always 404s.

    The problem is that you can’t just call the flush_rules in your functions.php after you register the taxonomy, it should only be called _once_ after you first register it, and again only after you unregister it.

    If you write a plugin its ok, as you can add this to the install and uninstall routine, but if you are taking advantage of 2.8′s improved taxonomy handling to do this in functions.php its not obvious how to include this sensibly – for testing I’ve just called it once, then commented it out and that works, but my theme is no longer portable.

    Justin – how have you handled this issue?

    Quick Correction – calling flush_rules in functions.php doesn’t work (you can still use it in a plugin), instead you can open the Permalink Settings page in admin, this triggers a flush_rules event.

    Having done this my taxonomy templates now work as expected for urls like mydomain.com/actor/tomhanks ie you can now use taxonomy-actor-tomhanks.php, taxonomy-actor.php and taxonomy.php.

    I still haven’t found a way to elegantly handle this in a theme however.

    hey justin, thanks for the reply.
    sorry, i’ve miswrote what i wanted to say.
    (i think what im requesting for has been brought up in the WP support forums before)

    it’s not that i want to show the actual terms… not in this case at least.
    what i’m aiming for is to show the posts that part of a specific taxonomy…or even… a specific term of that taxonomy. so i’m wondering, how would you go about building a query to rack together i.e any posts filed under the taxonomy of “WORK.”

    thanks again.

    vvvvv – Here is a query for getting all posts in a specific taxonomy term (in this case the taxonomy is called “locations” and the term I’m getting posts under is in a variable called $location_name):


    query( array( 'locations' => $location_name, 'showposts' => 5 ) );
    ?>

    I don’t know of a way to display all posts using any term in the “locations” taxonomy other than using custom SQL:


    SELECT *
    FROM $wpdb->posts
    LEFT JOIN $wpdb->term_relationships ON($wpdb->posts.ID = $wpdb->term_relationships.object_id)
    LEFT JOIN $wpdb->term_taxonomy ON($wpdb->term_relationships.term_taxonomy_id = $wpdb->term_taxonomy.term_taxonomy_id)
    WHERE $wpdb->posts.post_type = 'post'
    AND $wpdb->posts.post_status = 'publish'
    AND $wpdb->term_taxonomy.taxonomy = 'locations'
    ORDER BY $wpdb->posts.post_date DESC

    You’d then loop through the results and display. More info here: http://codex.wordpress.org/Displaying_Posts_Using_a_Custom_Select_Query

    Justin – I didn’t explain myself very well. Let’s say I have a query that returns all posts that are in one category and have a specified taxonomy term (or custom SQL or anything else outside the scope of typical archive/category/taxonomy pages). Right now, I would make a custom page template to contain that query and then create a WP page and give it some appropriate name and select the template. Page displays at mysite.com/page_name. Is that the best way to handle that situation? What if the query is ad-hoc based on some variables and it doesn’t make sense to use one specifically named WP page to display results?

    I just started reading the Custom Queries page in the Codex and may have answered my own question: http://codex.wordpress.org/Custom_Queries

    I can see this being very useful for some of my ongoing projects. Do you think it is possible to sort the resulting tags by number of clicks? Maybe increment them in the DB every time and use that to roll them up higher in the order they are shown? This is just one more step towards being able to use WP as a full blown content mgt system for all my needs. Thank you!

    Someone on this thread was asking about making custom templates for taxonomies. Taxonomy.php will get you started, but what about when someone clicks on the permalink of a post using a custom taxonomy? Assuming you want to preserve some context, like the side bar of posts using custom taxonomies.

    If you are in that position, this may help — I needed to create a custom single.php so that if a post is within a custom taxonomy it would show a different layout than a regular single post.

    This solves it for me:

    I put this code into single.php (clearing all other code out) then I created single-teaching.php and /single-default.php:

    $post = $wp_query->post;
    if ( is_taxonomy('Album') )
    	include(TEMPLATEPATH . '/single-teaching.php');
    else
    	include(TEMPLATEPATH . '/single-default.php');

    Basically, if the post has any tag from my “Album” custom taxonomy – then display that post using the file single-teaching.php otherwise if it does not have a tag from the ‘Album’ taxonomy applied, then display the post using single-default.php

    In my case, I have posts that are blog posts, and posts that are “lessons.” The lessons are chunked up into major and minor categories and finally down into individual posts that either sell a pack of lessons. The packs of lessons needed a link to enable drilling down to see a list starting with the offer for the pack of lessons, followed by each individual lesson.

    I’m using categories to create navigation through the lessons and for reasons too long to explain here, I found that creating this custom taxonomy called “Album” did the trick so that I could first display a feed of all the Albums belonging to a major or minor category, then provide that “View all albums in this series” link courtesy of the custom taxonomy “Album.” Clicking on the link shows each post having the same Album tag.

    This could not be done with categories+sub-categories or at least not as I could see, because Wordpress always wants to list all the categories a post belongs to. Sure, you can limit that by saying just display a category ID, but this needs to scale such that I can’t go hard coding category numbers in all the time.

    I didn’t want to use tags, because the lessons already have tags that describe the content of the lesson.

    Then, I discovered this additional bonus! Custom Single.php if my post is an “Album” ! How good are custom tags?!

    And another additional bonus I just realized while typing this. I can have lessons show up as parts of more than one album — allowing my client down the road to mix and match existing content just by assigning the same Album tag to any group of lessons.

    Thanks Justin for getting me started down this road!

    Hi Justin !

    Thanks to your tutorial, I’ve (quite) finaly done what I’ve ever wanted to do with WordPress (2.9): the most simple yet powerful CMS ever !

    I’m just at the start of putting together a new web site for a friend of mine’s record company, Bones Brigade records and I’ve been searching for months how to achieve what I’ve done in a few hours thanks to your post !

    I’ve posted the link for an example, even if the web site is not finished (at all!), the linked page is working and uses all of your stuff:
    - the page by itself is a category.php, namely the “artists” category file.
    - the “name” on the left is a list of the posts in this category (a post by artist),
    - the “genre” and “country” are list of the terms in the corresponding taxonomies, each term linking to a taxonomy-genre.php or taxonomy-country.php file (both under construction at the time of writing that comment, but working)
    - the “featured artist” area show a random post of the artists > featured sub-category
    - the “all artists” area starts with a list of the terms of the “letter” taxonomy, linking to a taxonomy-letter.php template while the pictures after that are, as the “name” area on the left, a list of the posts in the category “artists”.

    As of now, the only thing I haven’t been able to do is to redefine the query in order not to “select” artists by letter, name, genre or country, but to be able to choose a letter AND a country AND a genre to create a list of artists, i.e., but, all in all, this taxonomy thing just opened a whole Universe of new things to play with !

    A little more explanations in how to use the wp-tag-cloud classes to create unordered lists rather than a cloud would have save me some time, though :)

    So, I hope the example page would demonstrate the power of taxonomies and what can be created with WordPress and the reading of your post / its comments.

    Many, many thanks for the good work !

    Hope this comment would have been of interest.

    Cheers from France!

    Firstly, how do you create or assign this ‘http://popcritics.com/movies/the-junction-boys’ url permalink structure when your ‘http://popcritics.com/2010/05/03/hannah-montana-ends’?

    I’m trying to achieve or find a way to edit my permalinks for custom categories? Is this possible? I see from your popcritics.com, you’ve managed to do just that, where movies will start with ‘movies/movie-title’ and certain post will start with ‘year/month/date’ system…

    For example below:
    http://popcritics.com/movies/the-junction-boys – /%category/%postname%
    http://popcritics.com/2010/05/03/hannah-montana-ends – /%year%/%monthnum%/%day%/%postname%/

    Appreciate you can advice me on how to achieve the above? I’ve been posting the same question and googling around, it seems nobody has done this before or created a proper plugin for it…

    Hi,
    nice thing these taxonomies. And the movie website looks cool. How is the overview with all the movies made? That would be cool for my site, too.

    But now my question. On my site I want to create reviews for CDs, DVDs, Books and Concerts.

    Now it makes sence not to put all the new created taxonomies in the new posts (blog, content).

    For example, if I review a CD, I dont need, “Venue, City or Author”.
    When I review a Book, I need “Author, Artist, Publisher”
    Concerts I will need “Venue, City, Artist”

    Now I thought, I creat 4 diffrent Custom Posts And say, if I choose the Books Post, then show me, Author, Artist and Publisher taxonomies.

    An other thing is, do I still have to choose the Categorie that will be in my case REVIEW – Books or REVIEW – CDs?

    Can I still use Tags?

    Hi everyone,

    I am working on a project where i have a similar situation. I have successfully managed to create the first and individual pages for each actor.

    I have created a custom post type movies and have a page named page-movies.php which shows the list of all movies.

    Similarly, I have created a taxonomy Actors and have a page actors.php where i have the list of all the actors and a page taxonomy-actors.php which shows the details for the individual actor.

    I access my movies page by mysite.com/movies/ and it shows me the list of movies. When i click on a movie name it opens a page mysite.com/movies/movie-name/ with the description of the movie and the list of actors that acted in it. Whenever i click on any actor name the url is changed to mysite.com/actors/actor-name/ and the page shows the actors details and the list of movies that he has acted in.

    Everything fine till here.
    Now i have a page filmography.php which shows only the list of movies that the particular actor has acted in but the problem is i cannot make it to appenf to the url.

    What i would like to do is the filmography.php page be rendered when i type mysite.com/actors/actor-name/filmography or mysite.com/actors/actor-name/?filmography.php. Currently when i type the above url directly i get the page not found error. Also if anyone can tell me how do i create a link for filmography.php on the actor details page so that when i click on that link i am directed to mysite.com/actors/actor-name/filmography or mysite.com/actors/actor-name/?filmography.php with the desired result.

    Can anyone help.

    I am a complete novice in php and i tried whatever is explained above but failed. May be i am missing out on soemthing.

    Hoping for a quick response. ITS URGENT.

    Hi Justin — another great post in your series of informative articles about taxonomies. I’ve been custom field user for a while, especially with custom field template. This is an off beat question, and if ridiculous or not possible, tell me!

    Can I assign a custom field value to a taxonomy term? Why? I have the custom template boxes set up and all the assigned variables. If I want to “convert” them to taxonomy terms, can I? If so how? I know Scribu has a plugin for this purpose but I need to do it in code in the process of making the page.

    Thanks for this excellent post, Justin. It takes seeing a real example like you posted above to see the power of taxonomies. I’m just seeing now that I’m only scratching the surface.

    Thank you so much for this post.

    Is there a way to associate a custom taxonomy with users of the website, so that I can do this exact thing for original content? I’d like to be able to display the avatar and name of each person associated with the post. I’m essentially trying to create multiple “author” taxonomies, all with different names.

      Sorry to double post – just wanted to add that as examples, this type of functionality exists on funnyordie.com and vimeo.com

        Another thought! (sorry)

        A way around this (seemingly overly-complex) methodology I posted above might be to just associate images with taxonomy terms and keep it like your example. HOWEVER, what do you do in the case of Daniel Petrie Jr. in your Turner & Hooch example? How do you make it so you can click on him in either taxonomy and get to the same Daniel Petrie Jr. archive that displays ALL his credits (not just his writing credits or just his producing credits)?

    Thanks for this well written tutorial.

    Here’s a question, is it possible to create a page that queries multiple taxonomies?

    Using your example, say I wanted to find all the movies that were produced by Stephen Spielbierg IN the genre Fantasy.

    So basically sort by multiple taxonomies.

      Oh and it would also be good if those custom queries could go to a search engine friendly url, something like.

      http://domain.com/producer/stephenspielbierg/genre/fantasy/

    Many thanks, that was really easy and I had successfully created 6+ additional taxonomies for better classification of products.

    Can you please tell me how you created that movie database main page template to show that all movies in a separate boxes? And how you accessed the database with that custom search basis (like those with Tom Hanks)?

    I have been waiting for this ever since I read the Custom Post Type article a few weeks ago. Great info. Just today I was trying to figure out how to pull a title for my archive and your reply to Paul did the trick.

    Hi I have used the taxonomy picker plugin to try to select the page templates I have created using custom fields, but it only picks the content that is in the page editor and not the content in the template. Question is this possible.

    Thanks for the post,

    So I have written a piece of code (pasted here at the bottom) which grabs only the posts that have the term ‘vejer’ which is inside taxonomy ‘locations’ that I have created in my functions.php – I have a “stupid” questions though – How can I grab & put inside the loop ALL the terms inside ‘locations’ but not in any other taxonomy? I can’t manage to do that whatever I do !

    Thanks
    Amit

    'vejer')); ?>
    		<a href = "" 
    		rel = "bookmark" title = " 
    		"
    		alt = " 
    		"
    		>
    		
    		</a>

    Hi there, I have a mind block with taxonomies – maybe someone can help.

    I want to create a bunch of PAGES (not posts !!) for different products (around 300 pages), lets say a baseball cap for example. These pages will be my landing pages.

    Now I want my customers to be able to search by using different taxonomies, for example a) material (cotton, nylon, polyester, ..) b) product group (Headwear, Umbrellas, Eyewear, ..), but there seems to be no way to add a taxonomy to a PAGE.

    Does anyone have a suggestion for me ?

    Love this post! Learned a whole lot about taxonomies (which i’ve choose to ignore up until this point lol)

    I want to use them as a way to Filter out certain posts.

    Similiar to how its being used here: http://april77.com/portfolio/

    How can I use this tutorial to reach these results?
