  • How to Truncate description within post tags admin panel


    I had a few emails about truncating post tag descriptions similar to truncating category description snippet, here it is. Adding this snippet to the functions.php of your wordpress theme will truncate the description located within the tags admin panel. Change the number 150 on line 09 to adjust the number of characters for the post tags description.

    ( example screenshot ) ( click code to copy )

    wordpress snippet : PHP

    add_action( 'admin_head-edit-tags.php', 'admin_edit_post_tags' );
    function admin_edit_post_tags() {
        add_filter( 'get_terms', 'admin_trim_tag_description', 10, 2 );
    function admin_trim_tag_description( $terms, $taxonomies ) {
        if( 'post_tag' != $taxonomies[0] )
            return $terms;
        foreach( $terms as $key=>$term )
            $terms[$key]->description = substr( $term->description, 0, 150 );
            return $terms;

    ( WordPress codex functions, hooks, in this snippet. )
