finding menu hierachy > wp_get_nav_menu_items

Question

Hi I am building a menu using the code listed here.

http://codex.wordpress.org/Function_Reference/wp_get_nav_menu_items

Is there a way to suss out the menu hierarchy. As i can not debug this, it is difficult for me to see what wp_get_nav_menu_items actually returns.

$menu_items = wp_get_nav_menu_items($menu->term_id); 

or

<?php $items = wp_get_nav_menu_items($menu, $args = array()); ?> 

Is there a listing that describes the objects returned via wordpress functions?

Any help much appreciated.

Answer 1

Whenever i find myself not sure what kind of data is returned by a function i use my simple ready made var_dump_pre() function which i use heavily in developments, simply paste it in your theme's functions.php file.

function var_dump_pre($obj){
    echo '<pre>';
    var_dump($obj);
    echo <'/pre>';
}

Usage

say i want to see what wp_get_nav_menu_items actually returns:

$menu_items = wp_get_nav_menu_items($menu->term_id); 
var_dump_pre($menu_items);
