How to use get_taxonomy filter in WordPress

get_taxonomy filter

Alright, so you’re diving into the world of WordPress hooks, and today, let’s chat about the get_taxonomy filter. This filter is quite dynamic because it hinges on the $taxonomy slug. Now, before you can use it, you’ll need to register it using add_filter. You can pop this code into your theme’s functions.php or, better yet, into a custom WordPress plugin. Trust me, keeping it in a plugin is a smart move – it ensures that your work isn’t wiped out during a theme update.

Here’s the game plan: we define a function modify_get_taxonomy_defaults, which takes two parameters. We then register it with add_filter. The first parameter is the hook name, get_taxonomy, followed by the function name, priority, and the number of arguments.

Need to yank out a registered hook? Easy! Use remove_filter.

Example 1: Basic Usage

Let’s see a basic way to use the get_taxonomy filter.

    function weplugins_modify_get_taxonomy_defaults($_term, $taxonomy) { 
        // Update the $_term variable as needed.
        return $_term; 
    }
    // add the filter
    add_filter( "get_taxonomy", "weplugins_modify_get_taxonomy_defaults", 10, 2 );
    

Example 2: Removing a Hook

Here’s how you can remove the hook callback.

    remove_filter( "get_taxonomy", "weplugins_modify_get_taxonomy_defaults", 10, 2 );
    

Example 3: Conditional Modifications

Modify the $_term variable conditionally based on your needs.

    function weplugins_conditional_get_taxonomy_defaults($_term, $taxonomy) { 
        if ($taxonomy == 'category') {
            // Modify $_term for categories.
        }
        return $_term; 
    }
    add_filter( "get_taxonomy", "weplugins_conditional_get_taxonomy_defaults", 10, 2 );
