    This is so nice. Though I have no clue of why I would need such template, it seems that large news oriented sites may need it for something about BIG event or once-in-a-lifetime article which needs special attention.

    This is part of WordPress’s ability which has the sky limit… That is why we love WordPress.

    You should definitely throw it out as a plugin. It makes more sense as a plugin than as part of a theme as I think once someone has done this, if they switch themes, they are likely to want to continue that customisation.

    Hello Justin. I was just looking over the Custom Post Template Plugin at http://wordpress.org/extend/plugins/custom-post-template/ a few minutes ago. I was thinking that I would prefer a non-plugin solution ;-)

    @ Justin Tadlock,

    True. CSS can be implemented to change the look and feel of certain posts, using post IDs as classes as usual.

    But, I thought of how someone would use the technique explained in this tutorial, of course someone may use it when they want to change the normal content of the sidebar, navigation, header, footer, etc… Or when they want to add something extra in the posts template…

    Great tip though. I may need it someday.

    I’m sorry, what i meant that by reading this tutorial i understand that u could sort a page into certain category post(using string $cat right?), I thought by sorting it, u could divide the site into a new rss feed setting, the new page have another feed sorting but i forgot that this is a SINGLE post template, so my bad :)

    Your solution may be exactly what I was looking for.
    I’m going to open a blog in collaboration with a couple of friends and we were looking for a way to selectively display adsense ads. Every blog post single page should display only the code relative to the adsense account of the author of the post.

    Hi Justin
    You wrote “They should not be used to change the look (style, design) of a particular post though. You can do this with CSS.”

    J Mehmett also said:
    “CSS can be implemented to change the look and feel of certain posts, using post IDs as classes as usual.”
    How exactly do I assign different styles in CSS to different template?
    For example, I would like to have different styles for different authors, after creating different post templates for each of them.

    Awesome tutorial. I am in the process of designing a site that has 2 top-level categories with different templates, and was trying to figure out a way to give single posts matching templates depending on the top-level category. Since the site has many levels of sub-categories, this was becoming rather difficult. It seems using tag-specific single post templates is much more straightforward than finding a way to get the top-level category and assign a single post template that way. Thanks for the info!

    Well, I finally got round to doing this on the few posts that warranted it and its yet another powerful tool you’ve helped us with Justin – a pretty simple, yet elegant solution which I didn’t have to come up with myself!

    I think I just answered my own question if anyone is interested about using your single parent category template to include your subcategories, as well.
    Just add another elseif statement:

    elseif(file_exists(SINGLE_PATH . '/single-cat-' . $cat->category_parent . '.php'))
    return SINGLE_PATH . '/single-cat-' . $cat->category_parent . '.php';

    Hey, great tutorial. Got this up and running in a little experiment I’m undertaking.

    Because many of my posts will have images or extra CSS, I need a tidy way to store these post specific files so my site structure doesn’t become an absolute mess.

    What I need to know is how, instead of searching for single-“post ID” inside the folder /single, search for that template file inside a folder with the same post id.

    I’m simply not sure how to get the POST ID tag to work inside define(SINGLE_PATH.

    Thanks!

    Ok I want to blog about a video today… I better use my post temp for video!
    Now I want to blog about photography… better use my post temp for photo’s!
    Now I just want to write a straight forward post… better use the default!

    Currently I would have to leave the blog timeline and use pages to accomplish this…
    Although all the filter ideas are great… I would simply be happy to see the page templates functionality extended to posts… so I could select a template from a drop down menu as I can with pages…

    I would love to use a plugin that can do this… ;)

    p.s… I forgot to mention that each post template would have different functionality… i.e… a video post would have an area at the top of the page for the video (using the “simple-video-embedder”) and the photo template would have a similar area for the photo etc…

    Hope this makes sense… :)

    This is a terrific tutorial but it allows me to ALMOST do what I want. I’m just wondering, is there a way to make a template for a combination of two tags? I want to include specific custom fields on pages tagged with ‘film’ and ‘review’ and I think your above methods are the closest to the easiest way to achieve this. I may be wrong, but it’s my current course of action. :P

    If I could create a template like single-tag-film-review.php and have it only be used when those specific tags are used, I’d be a ridiculously happy camper. Any help with this would be GREATLY appreciated.

    Thanks,

    Thanks Justin! This tutorial is just what I was looking for.

    For the people wondering how this might be used, I’m making a portfolio site where each project will have multiple blog posts about it but one post will contain the project summary. I want to have a special template for those summary posts that shows the summary, all the images related to the project, lists all the projects blog posts, and has a unique layout to look like a portfolio rather than a blog. I’ll have a landing page for projects that will query just these summary posts and display them portfolio style.

    I’m planning on using a custom field to differentiate the summary posts from the rest so hoping to modify this code for that purpose. Any ideas would be greatly appreciated.

    It looks like the Custom Post Template plugin can probably accomplish this but I’d rather code something I can customize and maintain as needed.

    Thanks again Justin… Best wordpress info blog I’ve found on the web…

    Hi Justin,
    I’ve a couple of questions on this approach:

    1. Has get_the_tags changed with the 2.8.2 release? I’d been writing my own single post function and got stuck with get_the_tags returning false all the time, when I’ve tried your code it also seems to return false on the get_the_tags call… any thoughts?

    2. I notice you set the in_the_loop query property false before calling get_the_tags and then reset it after the foreach loop. I thought that might have been my problem for a while, but it wasn’t :-(

    However I’m confused, if you find a tag template you’ll return without ever resetting the in_the_loop flag to false, and if I read this right your using the global wp_query object – can this ever be a problem?

Found the plug-in for choosing a single post template, but did not want to rely on the client remembering to choose it when they enter a new post. Your method means they don’t have to think about it.

    And I’m not a coder, but I was able to follow your step-by-step directions and get it working a just a few minutes. I found some other instructions elsewhere that seemed like they might be what I need, (http://codex.wordpress.org/Theme_Development#Query-based_Templates), but they did not spell out exactly where to paste the code.

After a good hour or so of panic I thought to delete the edited functions file and replace it with an original, and voila I could login again.

    I’m currently using this method on my company’s site. Thanks!

    I want to take things up one level, though, and use different templates for a single post depending on the URL (based on category).

    Let’s say the default for each post is: /post/foo.html
    And I want to use a different template for the private version, which is: /post/private/foo.html

    (It serves up different content using different custom fields.)

    I can use redirect rules to control access to the private version. The trouble is, each post exists in _both_ categories, so it will always use one or the other as the template. I want to use /private/ only when someone goes to that specific URL. Under this current setup, Wordpress is serving up every /post/foo.html using the private template because it also happens to be in the private category.

    Can I fix this with changes to the functions.php file?

    In any case, thanks for all your help.

    This looks really useful, thanks for putting it out there.

    The use that springs to mind is the scenario I’m trying to implement at the moment- I have a particular category of posts that use custom fields, so I need to have custom templates for displaying the additional meta information for just these particular posts and the archive pages for these posts. Wordpress already seems to have the functionality for custom category templates, but I need to do the same thing at the single-post level, too.

    i am trying to create a post template so that i can use a set template everytime i add a post for my universities i am listing.

    I need to create a template so that when I want to load the individual universities as individual posts I get a custom template to fill in.. the individual unis will be loaded as posts under category ‘university listing’

    eg it will load the headings for the post onto the page and i then jsut paste the text into it and save it.

    http://www.postgraduatesinsport.com/wp-content/uploads/2010/04/BIRKBECK-UNIVERSITY-OF-LONDON.pdf is an example of the layout of what I want to create. It will appear as a post each time… so basically I need a template designed that me or my staff can use to load unis etc…

    Top section will have :

    Uni logo, uni contact details
    Profile
    Courses
    Web link

    Mid section:
    INSIGHT – STUDENT EXPERIENCE
    The text will be pasted in so just the header need here…
    Would like to have a video inbedded on the right with an interview with the student there… thumbnail video inbedded

    Bottom section:
    COURSE PROFILE
    Age
    Men/Women Ratio
    Careers Students have gone into

    Straightforward really. Just need the headings set into a post template called pageofuniversityposts.php or something like that….

    When I then load a post and select this template, it will load the template headings and we just need to paste the text and insert the logo and video and away we go!!

    Love this and have used it a few times, particularly for the category-specific templates. With a new site using custom post types though, I am encountering a problem with the default use of single-{post-type} not returning the single template for the custom post type.

    How would I modify the code above to maintain the category specific single post templates while also enabling the single post type ones?

      Got my question answered on WordPress StackExchange here: http://wordpress.stackexchange.com/questions/13837/conflict-in-function-to-allow-single-post-template-based-on-category

      Here’s the code:

      /* Define a constant path to our single template folder */
      define(SINGLE_PATH, TEMPLATEPATH . '/single');
      
      /* Filter the single_template with our custom function*/
      add_filter('single_template', 'my_single_template');
      
      /* Single template function which will choose our template*/
      function my_single_template($single) {
          global $wp_query, $post;
      
      /* Checks for single template by post type */
      if ($post->post_type == "POST TYPE NAME"){
          if(file_exists(SINGLE_PATH . '/single-' . $post->post_type . '.php'))
              return SINGLE_PATH . '/single-' . $post->post_type . '.php';
      }
      
      /* Checks for single template by category. Check by category slug and ID */
      foreach((array)get_the_category() as $cat) :
      
          if(file_exists(SINGLE_PATH . '/single-cat-' . $cat->slug . '.php'))
              return SINGLE_PATH . '/single-cat-' . $cat->slug . '.php';
      
          elseif(file_exists(SINGLE_PATH . '/single-cat-' . $cat->term_id . '.php'))
              return SINGLE_PATH . '/single-cat-' . $cat->term_id . '.php';
      
      endforeach;
      
      /*Checks for default single post files within the single folder */
      if(file_exists(SINGLE_PATH . '/single.php'))
          return SINGLE_PATH . '/single.php';
      
      elseif(file_exists(SINGLE_PATH . '/default.php'))
          return SINGLE_PATH . '/default.php';
      
      return $single; 
      }

      and just replace “POST TYPE NAME” with your custom post type name.

    Thanks

    Thanks Scott for your code! But I found a problem, what about sub-sub categories? Or sub-sub-sub-sub categories? :D
    This is the complete code that I added to my functions.php

    function pa_category_top_parent_id ($catid) {
     
     while ($catid) {
      $cat = get_category($catid); // get the object for the catid
      $catid = $cat->category_parent; // assign parent ID (if exists) to $catid
      // the while loop will continue whilst there is a $catid
      // when there is no longer a parent $catid will be NULL so we can assign our $catParent
      $catParent = $cat->cat_ID;
     }
     
    return $catParent;
    }
    
    
    //-----------------------------------------------------------
    //funcion para mostrar un single template para cada categoria
    /**
    * Define a constant path to our single template folder
    */
    define(SINGLE_PATH, TEMPLATEPATH . '/single');
    
    /**
    * Filter the single_template with our custom function
    */
    add_filter('single_template', 'my_single_template');
    
    /**
    * Single template function which will choose our template
    */
    function my_single_template($single) {
    	global $wp_query, $post;
    
    /**
    	* Checks for single template by category
    	* Check by category slug and ID
    	*/
    	foreach((array)get_the_category() as $cat) :
    
    		
    		$categoriapadre= pa_category_top_parent_id ($cat);
    		
    		if(file_exists(SINGLE_PATH . '/single-cat-' . $cat->term_id . '.php'))
    			return SINGLE_PATH . '/single-cat-' . $cat->term_id . '.php';
    		
    		elseif(file_exists(SINGLE_PATH . '/single-cat-' . $categoriapadre . '.php'))
    			return SINGLE_PATH . '/single-cat-' . $categoriapadre . '.php';	
    
    	endforeach;
    return $single;
    
    }

    Can this be set up for single files assigned to a Custom Taxonomy?

    As currently its just for default categories…

    Thanks :)

      I think I got it, just change ‘taxonomy_name’ to whatever your custom taxonomy is called.

      /**
      	* Checks for single template by category
      	* Check by category slug and ID
      	*/
      	foreach((array)get_the_terms($post->ID,'taxonomy_name') as $cat) :
      
      		if(file_exists(SINGLE_PATH . '/single-cat-' . $cat->slug . '.php'))
      			return SINGLE_PATH . '/single-cat-' . $cat->slug . '.php';
      
      		elseif(file_exists(SINGLE_PATH . '/single-cat-' . $cat->term_id . '.php'))
      			return SINGLE_PATH . '/single-cat-' . $cat->term_id . '.php';

    I’m with Jez, is it possible to modify it to pull a template based on a Custom Taxonomy?

    I was just looking to make a simple template file for a particular post. I just wondered why it was not so easy as making it for a particular page and trying out numerous things

    I am glad to know how to create it by your article. Thank you

    Hi Justin

    I am late for the party, only now I got around trying to create single post templates..

    your solution is great, but my problem is, it does not include support subcategories,

    so, it means, I would have to create 20-30 single post templates which would be impossible to maintain :(

    any idea how to add sub categories support?

    thanks

    Could this method be modified to handle custom Taxonomies?

    If so how could it be done?

    Cheers :)
