Walker Nav Menu Depth

I’ve been looking for a way to add spans to my mobile menu so they can be targeted with jQuery.

I found a custom walker_nav_menu and it works well and adds a span to menu items which have children.

However, it will only add a span to menu items 3 deep. It won’t add a span to the 4th level deep menu item even if it has children.

Here’s the code:

class Nav_Walker_Nav_Menu extends Walker_Nav_Menu {
function start_el( &$output, $item, $depth = 0, $args = array(), $id = 0 ) {
global $wp_query;
$indent = ( $depth ) ? str_repeat( “t”, $depth ) : ”;

$class_names = ”;

$classes = empty( $item->classes ) ? array() : (array) $item->classes;
$classes[] = ‘menu-item-‘ . $item->ID;

$class_names = join( ‘ ‘, apply_filters( ‘nav_menu_css_class’, array_filter( $classes ), $item, $args ) );
$class_names = $class_names ? ‘ class=”‘ . esc_attr( $class_names ) . ‘”‘ : ”;

$id = apply_filters( ‘nav_menu_item_id’, ‘menu-item-‘. $item->ID, $item, $args );
$id = $id ? ‘ id=”‘ . esc_attr( $id ) . ‘”‘ : ”;

$output .= $indent . ‘<li’ . $id . $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;
$item_output .= ‘<a’. $attributes .’>’;
$item_output .= $args->link_before . apply_filters( ‘the_title’, $item->title, $item->ID ) . $args->link_after;
$item_output .= ‘</a>’;

if ( ‘mobile’ == $args->theme_location ) {
$submenus = 0 == $depth || 1 == $depth ? get_posts( array( ‘post_type’ => ‘nav_menu_item’, ‘numberposts’ => 1, ‘meta_query’ => array( array( ‘key’ => ‘_menu_item_menu_item_parent’, ‘value’ => $item->ID, ‘fields’ => ‘ids’ ) ) ) ) : false;
$item_output .= ! empty( $submenus ) ? ( 0 == $depth ? ‘<span class=”mobile-opener”><i class=”fa fa-angle-down” aria-hidden=”true”></i></span>’ : ‘<span class=”mobile-opener”><i class=”fa fa-angle-down” aria-hidden=”true”></i></span>’ ) : ”;
}

$item_output .= $args->after;

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

The code causing the issue is this:

if ( ‘mobile’ == $args->theme_location ) {
$submenus = 0 == $depth || 1 == $depth ? get_posts( array( ‘post_type’ => ‘nav_menu_item’, ‘numberposts’ => 1, ‘meta_query’ => array( array( ‘key’ => ‘_menu_item_menu_item_parent’, ‘value’ => $item->ID, ‘fields’ => ‘ids’ ) ) ) ) : false;
$item_output .= ! empty( $submenus ) ? ( 0 == $depth ? ‘<span class=”mobile-opener”><i class=”fa fa-angle-down” aria-hidden=”true”></i></span>’ : ‘<span class=”mobile-opener”><i class=”fa fa-angle-down” aria-hidden=”true”></i></span>’ ) : ”;
}

Any help appreciated.

Thanks in advance.
