arrays - Modifying a PHP collection -


for wordpress website i'm developing, i'm making dynamic menu users can make using admin menu. hooking least of problems.

the code i'm using returns these arrays:

                        array (     [0] => wp_post object         (             [id] => 35             [post_author] => 1             [post_date] => 2013-05-19 15:46:22             [post_date_gmt] => 2013-05-19 15:46:22             [post_content] =>               [post_title] =>              [post_excerpt] =>              [post_status] => publish             [comment_status] => open             [ping_status] => open             [post_password] =>              [post_name] => 35             [to_ping] =>              [pinged] =>              [post_modified] => 2013-05-19 16:07:09             [post_modified_gmt] => 2013-05-19 16:07:09             [post_content_filtered] =>              [post_parent] => 0             [guid] => http://adapt.local/?p=35             [menu_order] => 1             [post_type] => nav_menu_item             [post_mime_type] =>              [comment_count] => 0             [filter] => raw             [db_id] => 35             [menu_item_parent] => 0             [object_id] => 32             [object] => training             [type] => post_type             [type_label] => training             [url] => http://adapt.local/training/alcohol/             [title] => alcohol             [target] =>              [attr_title] =>              [description] =>              [classes] => array                 (                     [0] =>                  )              [xfn] =>          )      [1] => wp_post object         (             [id] => 36             [post_author] => 1             [post_date] => 2013-05-19 16:07:09             [post_date_gmt] => 2013-05-19 16:07:09             [post_content] =>               [post_title] =>              [post_excerpt] =>              [post_status] => publish             [comment_status] => open             [ping_status] => open             [post_password] =>              [post_name] => 36             [to_ping] =>              [pinged] =>              [post_modified] => 2013-05-19 16:07:09             [post_modified_gmt] => 2013-05-19 16:07:09             [post_content_filtered] =>              [post_parent] => 0             [guid] => http://adapt.local/?p=36             [menu_order] => 2             [post_type] => nav_menu_item             [post_mime_type] =>              [comment_count] => 0             [filter] => raw             [db_id] => 36             [menu_item_parent] => 35             [object_id] => 32             [object] => training             [type] => post_type             [type_label] => training             [url] => http://adapt.local/training/alcohol/             [title] => alcohol             [target] =>              [attr_title] =>              [description] =>              [classes] => array                 (                     [0] =>                  )              [xfn] =>          )  )

to explain: if menu_item_parent = 0, means top-node, , if menu_item_parent > 0, means 'subnode'.

i want convert horrible array more useful, preferably this

array (     [35] => array     (         name => "topnode"         url => "http://topnodeurl"         items => array         (             name => "subnode"             url => "http://subnodeurl"         )     ) )

i thought: hey, couldn't hard. but, apparently, doesn't seem work:

foreach($menuitems $menuitem) {     if(!$menuitem->menu_item_parent) {         $items[$menuitem->id] = array("name" => $menuitem->title,"items" => array());         #print_r($items);     }     else {         $parent = $items[$menuitem->menu_item_parent]['items'];         $parent = array("name" => $menuitem->title, "url" => $menuitem->url);     } }

any ideas?

make recursive function

function make_menu($items, $parent_id = 0) {     $menu = [];     foreach($items $key => $item) {         if (item['menu_item_parent'] == $parent_id ) {             $item['childs'] = make_menu($items, $item['id']);             $menu[] = $item;              // helps speed foreach removing items not needed more             unset($item[$key]);         }     }      return $menu; }

this way can have deeper function 1 layer
