    The get_taxonomies_for_attachments() function in WordPress is designed to retrieve all the taxonomies that are registered for attachments. Here's a detailed explanation of its functionality and usage:

    Function:

    • get_taxonomies_for_attachments(string $output = ‘names’): string[]|WP_Taxonomy[]

    Description:

    • This function is used to handle and retrieve mime-type-specific taxonomies, particularly for attachments like images and videos. It is specifically tailored to work with attachments and their associated taxonomies in WordPress.

    Parameters:

    • $output (string, optional): Specifies the type of output you want the function to return. It accepts two values:
      • 'names': If you want the function to return an array of taxonomy names.
      • 'objects': If you prefer the function to return an array of WP_Taxonomy objects.
      • The default value for this parameter is 'names'.

    Return:

    • string[]|WP_Taxonomy[]: Depending on the $output parameter, this function returns either an array of taxonomy names (strings) or an array of WP_Taxonomy objects. These are the taxonomies that are registered for attachments in WordPress.

    Sample Usage:

    Here's an example of how you might use get_taxonomies_for_attachments() in a WordPress theme or plugin:

    To get taxonomy names for attachments:

    $attachment_taxonomies = get_taxonomies_for_attachments();
    foreach ( $attachment_taxonomies as $taxonomy ) {
        echo $taxonomy . '<br>';
    }
    

    This code will list all the taxonomy names that are registered for attachments.

    To get taxonomy objects for attachments:

    $attachment_taxonomies = get_taxonomies_for_attachments('objects');
    foreach ( $attachment_taxonomies as $taxonomy ) {
        echo $taxonomy->label . '<br>';
    }
    

    This code will list all the taxonomy labels that are registered for attachments, using WP_Taxonomy objects.

    See Also:

    • get_taxonomies(): This is another WordPress function you might want to look into, as it retrieves taxonomies for other post types and could be useful in similar contexts.

    This function is particularly useful for developers working with media library items in WordPress, allowing them to categorize and manage attachments more effectively.
