Function and usage of get_tags_to_edit() in wordpress


Answers ( 1 )


    The get_tags_to_edit() function in WordPress is designed to retrieve a comma-separated list of tags that are available for editing for a specific post. This function is particularly useful when you're working with the WordPress backend, specifically in scenarios involving post editing or customization of the post editing interface.

    Function Prototype:

    get_tags_to_edit( int $post_id, string $taxonomy = 'post_tag' ): string|false|WP_Error


    1. $post_id (int, required): This parameter is the ID of the post for which the tags need to be fetched. The post ID uniquely identifies each post in WordPress.

    2. $taxonomy (string, optional): This parameter specifies the taxonomy for which to retrieve the terms. The default value is 'post_tag', which refers to the standard tags associated with posts. This parameter can be changed to other taxonomies if you have custom taxonomies defined in your WordPress setup.

      Default value: 'post_tag'

    Return Values:

    • string: If the function is successful, it returns a comma-separated list of tags for the specified post.

    • false: The function returns false if there are no tags to edit or if the post does not exist.

    • WP_Error: If an error occurs while fetching the tags, the function returns an instance of WP_Error.

    Sample Usage:

    Here is an example of how get_tags_to_edit() can be used:

    $post_id = 123; // Replace with the actual post ID
    $tags_to_edit = get_tags_to_edit($post_id);
    if (is_string($tags_to_edit)) {
        echo "Tags for editing: " . $tags_to_edit;
    } elseif (is_wp_error($tags_to_edit)) {
        echo "Error: " . $tags_to_edit->get_error_message();
    } else {
        echo "No tags available for editing or post does not exist.";

    In this example, $post_id should be replaced with the actual ID of the post you're working with. The function get_tags_to_edit() is called with this post ID, and the returned value is checked to determine whether it's a string (a list of tags), a WP_Error (an error occurred), or false (no tags available or post doesn't exist).

    This function is particularly useful for plugin developers or theme designers who need to provide a custom interface for tag editing or need to programmatically access the tags associated with a post.
