How to use get_the_terms filter in WordPress

To use the get_the_terms filter, you first need to register it using add_filter. You can add this code to your theme’s functions.php file or create a custom WordPress plugin. At WePlugins, we always recommend creating a custom plugin to ensure your customizations stay intact during theme updates.

Sometimes, you might need to remove a registered hook, and for that, remove_filter comes to the rescue. Let’s check out some live examples!

Example 1: Basic Usage

Below is an example of how you can use this hook to modify the terms attached to a post based on your requirements.

        function weplugins_modify_get_the_terms_defaults($terms, $post_id, $taxonomy) { 
            // Update the $terms variable according to your website requirements and return this variable.
            // You can modify the $terms variable conditionally too if you want.
            return $terms; 
        }
        // add the filter
        add_filter("get_the_terms", "weplugins_modify_get_the_terms_defaults", 10, 3);
        

Example 2: Removing a Hook Callback

To remove a hook callback, use the example below. Ensure you provide the same callback function name, priority, and number of arguments while removing the hook.

        remove_filter("get_the_terms", "weplugins_modify_get_the_terms_defaults", 10, 3);
        

Example 3: Advanced Customization

In this example, we show how you can conditionally modify terms based on specific taxonomy.

        function weplugins_advanced_modify_get_the_terms($terms, $post_id, $taxonomy) {
            if ($taxonomy == 'category') {
                // Custom logic for category terms
                foreach ($terms as $key => $term) {
                    // Modify term object as needed
                }
            }
            return $terms;
        }
        add_filter("get_the_terms", "weplugins_advanced_modify_get_the_terms", 10, 3);
