Introduction to the reset_default_labels method in the WP_Taxonomy class

Hello! Today we want to discuss the method reset_default_labels in the WP_Taxonomy class in WordPress. This method is one of the important tools that we can use in the design and development of plugins and themes for WordPress. You might be wondering what this method is used for?

In simple language, reset_default_labels is a function that resets the default labels of a custom taxonomy or term. Imagine that you have created a custom taxonomy and have set specific labels for it, but due to some reason, you want to revert to the original default settings. This method gives you the ability to easily restore the default labels for your custom class.

This method automatically works for every existing taxonomy in WordPress. In other words, you can use this method for labels, taxonomies, or even for your custom taxonomies. In fact, this feature helps you in case you need to switch back to the default settings if necessary. You can easily use the default labels for your taxonomy in WordPress.

Additionally, by using this method, you no longer need to worry about changes that might accidentally occur in the settings you have made, but you won't have to worry either. For this reason, this method is quite efficient and practical. Now let's take a look at a practical example to see how we can use this method.

Practical example of reset_default_labels

// Create a custom taxonomy
function my_custom_taxonomy() {
    register_taxonomy(
        'my_taxonomy',
        'post',
        array(
            'labels' => array(
                'name' => __( 'My Taxonomy' ),
                'singular_name' => __( 'My Taxonomy Item' )
            ),
            'public' => true,
            'hierarchical' => true
        )
    );
}
add_action('init', 'my_custom_taxonomy');

// Use reset_default_labels
function reset_my_taxonomy_labels() {
    $taxonomy = 'my_taxonomy';
    global $wp_taxonomies;
    if ( isset( $wp_taxonomies[$taxonomy] ) ) {
        $wp_taxonomies[$taxonomy]->reset_default_labels();
    }
}
add_action('init', 'reset_my_taxonomy_labels');

Code explanations

In the above code, we first use the register_taxonomy function to create a custom taxonomy named my_taxonomy.

Next, we define a function named reset_my_taxonomy_labels where we want to reset the labels of this custom taxonomy.

By using global $wp_taxonomies, we gain access to the list of all taxonomies. Then we check whether my_taxonomy exists in that list or not, and we call the reset_default_labels method to restore the labels.

Finally, we use the add_action function to add the reset_my_taxonomy_labels function to the init action so that this configuration is applied at the appropriate time.
