use value returned from shortcode as menu item

Question

I have a menu that I created in Appearance -> Menus. One of it's items is the company phone number which is set in the theme customizer. I have a shortcode that will return that number:

/* shortcode to display phone number  */
function getPhone()
{
    return get_theme_mod( 'contact_phone_data');;
}

/* Add shortcode */
add_shortcode('contact_phone', 'getPhone');

Is there any way to use this in the Appearance -> Menus UI? when I enter [contact_phone] into the menu item's 'Navigation Label' field, it (as expected) displays the actual string rather than executing the shortcode.

Is there a way to indicate that the value of that field should be executed as a shortcode? If not, is there a standard way that this type of thing is handled in WP?

Answer 1

Someone posted a similar question in the Advanced WordPress facebook group. I suggested adding some token text to the menu item's url and then swapping it out during render.

add_filter( 'nav_menu_link_attributes', 'dcwd_nav_menu_link_attributes', 10, 4 ); 
function dcwd_nav_menu_link_attributes( $atts, $item, $args, $depth ) {
    // If PHONE_NUMBER is found then change it.
    if ( false !== strpos( $atts[ 'href' ], 'PHONE_NUMBER' ) ) {
        $atts[ 'href' ] = getPhone();
    }
    return $atts;
}
