Parameters (3)

Usage

To run the hook, copy the example below.

$array = apply_filters( 'nav_menu_css_class', $array, $item, $args ); 
                         
if ( !empty( $array ) ) { 
                         
   // everything has led up to this point... 
                         
} 
  

The following example is for adding a hook callback.

// define the nav_menu_css_class callback 
function filter_nav_menu_css_class( $array, $item, $args ) { 
    // make filter magic happen here... 
    return $array; 
}; 
         
// add the filter 
add_filter( 'nav_menu_css_class', 'filter_nav_menu_css_class', 10, 3 ); 

To remove a hook callback, use the example below.

// remove the filter 
remove_filter( 'nav_menu_css_class', 'filter_nav_menu_css_class', 10, 3 );
