How to use get_terms_defaults filter in WordPress

get_terms_defaults filter

So, you’re diving into the world of WordPress hooks, huh? Well, today, let’s chat about the get_terms_defaults filter. This one’s pretty handy when you’re looking to customize the default arguments passed to the get_terms() function. To make this work, you’ll need to register the hook using add_filter. You could put this code in your theme’s functions.php or even better, create a custom WordPress Plugin. WePlugins always recommends creating a plugin to ensure your changes don’t disappear when updating your theme!

Example 1: Basic Usage

Here’s how you can modify the default arguments for the get_terms() function using get_terms_defaults.

    function weplugins_modify_get_terms_defaults($defaults, $taxonomies) {
        // Customize the $defaults array to suit your needs
        return $defaults;
    }
    add_filter('get_terms_defaults', 'weplugins_modify_get_terms_defaults', 10, 2);
    

Example 2: Removing a Hook

Need to remove a registered hook? No problem! Just make sure you provide the same callback function, priority, and number of arguments.

    remove_filter('get_terms_defaults', 'weplugins_modify_get_terms_defaults', 10, 2);
    

Example 3: Conditional Defaults

This example demonstrates how to conditionally modify the default arguments based on your requirements.

    function weplugins_conditional_terms_defaults($defaults, $taxonomies) {
        if (in_array('category', $taxonomies)) {
            // Customize defaults for categories
        }
        return $defaults;
    }
    add_filter('get_terms_defaults', 'weplugins_conditional_terms_defaults', 10, 2);
    

Remember, the key here is to adapt the defaults to match your site’s needs. And if you’re ever in a pickle or looking for some customization, don’t hesitate to reach out!
