How can I display the parent menu item’s description using WordPress walkers?

2 Views

Is there any way to pass a variable from start_el to start_lvl? I want to place the menu description in the wrapper of the submenu items. 

class submenu_walker extends Walker_Nav_Menu
{
    function start_lvl( &$output, $depth = 0, $args = array() ) {
        $indent = str_repeat("t", $depth);
        $output .= "n$indent<ul class='sub-menu'><div class='menu-image-container'><div class='menu-image'></div></div>n";
    }
    function end_lvl( &$output, $depth = 0, $args = array() ) {
        $indent = str_repeat("t", $depth);
        $output .= "$indent<div class='clear'></div></ul>n";
    }
}

I’ve tried to store the description as a variable in start_el, and access it using global in start_lvl… but it returns nothing.

  1. Here is the way to use this code and it will display the parent description.
    Steps for using of it.
    1: Copy the below class and past into the functions.php file.
    2: Call the menu like

     wp_nav_menu(array(
      'menu_id'=>'',
      'menu_class'=>'',
      'container'=>'',
      'theme_location'=>'#enter theme location#',
      'walker'=> new customize_menu_walker()
    ));
<br/>

    3:See the result.

    class customize_menu_walker extends Walker_Nav_Menu
{
 function start_el(&$output, $item, $depth, $args)
      {
           global $wp_query;
           $indent = ( $depth ) ? str_repeat( "t", $depth ) : '';

           $class_names = $value = '';

          // $dbclasses=$item->classes;
           $classes = empty( $item->classes ) ? array() : (array) $item->classes;

           $dbclasses=$class_names = join( ' ', apply_filters( 'nav_menu_css_class', array_filter( $classes ), $item ) );
           $class_names = ' class="'. esc_attr( $class_names ) . '"';

           $attributes  = ! empty( $item->attr_title ) ? ' title="'  . esc_attr( $item->attr_title ) .'"' : '';
           $attributes .= ! empty( $item->target )     ? ' target="' . esc_attr( $item->target     ) .'"' : '';
           $attributes .= ! empty( $item->xfn )        ? ' rel="'    . esc_attr( $item->xfn        ) .'"' : '';
           $attributes .= ! empty( $item->url )        ? ' href="'   . esc_attr( $item->url        ) .'"' : '';



            $item_output = $args->before;

             //specially for two menu
             //specially for two menu
           //convert string to array
           $dbclassesArr = explode(" ",$dbclasses);

           $item_output .= '<a'. $attributes .'>';

           if(in_array("menu-item-has-children", $dbclassesArr)){
             $description  = ! empty( $item->description ) ? '<span>'.esc_attr( $item->description ).'</span>' : '';//description display here.
           }

            $item_output .= $args->link_before .apply_filters( 'the_title', $item->title, $item->ID );
            $item_output .= $description.$args->link_after;
            $item_output .= ' '.'</a>';
            $item_output .= $args->after;

            $output .= apply_filters( 'walker_nav_menu_start_el', $item_output, $item, $depth, $args );
            }
}

    Now after updating this function, your menu will show the parent menu description.
    Here is the code.

    Thanking you.
