Is there a way to execute a custom PHP script inside a meta field?

  • Resolved Rogerio Dec

    I’d like to list all my product categories inside the main description of my store page.
    For example:

    “Now our products”: %categorie1%, %categorie2% … %categorie_n&”

    Is it possible?

  • Hello,

    Thank you for contacting Rank Math today.

    Yes this is possible, you can create a custom variable replacement that lists all the taxonomy terms using the following filter:

     * Filter to add custom variables
    add_filter( 'rank_math/vars/replacements', function( $vars ) {
     return $vars;

    Looking forward to helping you. Thank you.


    Right, found in

    I put this on my themes funcion.php, right?

    But how to get these values inside the page?

    HI Rogerio,

    Thanks for the follow up.

    Yes this will go in your theme’s functions.php file but you will need to come up with some additional arguments to get the products categories and return them when this variable is called.
    Here is an example of how this would look:

    add_action( 'rank_math/vars/register_extra_replacements', function() {
       RankMath\Helper::register_var_replacement( 'Category_list',array('Rank_math_list_cats'),$args = array(
    	        'name'    => esc_html__( 'List of categories', 'rank-math' ),
    			'desc'    => esc_html__( 'Categories from products', 'rank-math' ),
    			'example' => esc_html__(Rank_math_list_cats())));
    } );
    function Rank_math_list_cats(){
    	    $list = array();
            $orderby = 'name';
            $order = 'asc';
            $hide_empty = false ;
            $cat_args = array(
               'orderby'    => $orderby,
               'order'      => $order,
               'hide_empty' => $hide_empty,
            $product_categories = get_terms( 'product_cat', $cat_args );
            if( !empty($product_categories) ){
            foreach ($product_categories as $key => $category) {
            $list[] = $category->name;
    	    $cat_list = implode(", ",$list);
    	    return $cat_list;

    The code above registers a variable called %Category_list% that will display a comma separated list of categories.

    I hope this info helps. Thank you.
