I could use some help though /*noob alert*/

Where is the proper place to paste the code that Justin provided at the beginning of this post. I know it’s in the functions.php file, but where specifically should it be posted. I see other filters in the file, but every time I paste it, I get an error…

Thanks for your help!

I can remove a single “widget area”, ie. an entire sidebar, but can’t seem to target individual widgets within a widget area.

This works:

add_filter ('sidebars_widgets', 'remove_text_widget');
function remove_text_widget( $sidebars_widgets ){
	if (is_page(15))
		$sidebars_widgets ['sidebar'] = false;
	return $sidebars_widgets;
}

This doesn’t:

add_filter ('sidebars_widgets', 'remove_text_widget');
function remove_text_widget( $sidebars_widgets ){
	if (is_page(15))
		$sidebars_widgets ['text-5'] = false;
	return $sidebars_widgets;
}

$sidebars_widgets = get_option('sidebars_widgets');
foreach ($sidebars_widgets as $index=>$widgets) {
	if ($index!='wp_inactive_widgets' && $index!='array_version') {
		if(!empty($widgets) ){
			foreach($widgets as $n){
				echo 'Widgets in use: '.$n.'';
			}
		}
	}
	if($index=='wp_inactive_widgets'){
			foreach($widgets as $n){
				echo 'Widgets inactive: '.$n.'';
			}
	}
}

There you can see i’m able to get all active and inactive widgets, not the widgets areas, each widget id.

So, then i can run a single wp_unregister_sidebar_widget([some_id]); to disable any widget from any page or post.

But, i can’t figure how to do the reverse thing, i mean to register dinamicly one of the inactive ones in a certain widget area.

Got what i mean?

Well, that’s it, you have my email, pleas reply if you found how to. Thanks.
