i have 2 different displays here. 1 mobile , desktop. need output different html both 1 menu item (the last 1) in menu. example, given following menu structure:
- menu item 1 -- child 1 -- child 2 -- child 3 - menu item 2 -- child 1 -- child 2 -- child 3 -- child 4 - menu item 3 -- child 1 -- child 2 -- child 3 -- child 4 -- child 5 -- child 6 i need able output following structure desktop:
<ul> <li>menu item 1 <ul> <li>child 1</li> <li>child 2</li> <li>child 3</li> </ul> </li> <li>menu item 2 <ul> <li>child 1</li> <li>child 2</li> <li>child 3</li> <li>child 4</li> </ul> </li> <li>menu item 3 <ul> <li>child 1</li> <li>child 2</li> <li>child 3</li> </ul> </li> <li> <ul> <li>child 4</li> <li>child 5</li> <li>child 6</li> </ul> </li> </ul> the last parent menu item $depth === 0 needs split in half separate items. on mobile display, not need split in half, should display perfect mobile.
so have 2 different wp_nav_walker extending classes. 1 mobile , desktop handle menu differently, problem i'm facing how total count of submenu items. understand how know if menu has children or not using $args->has_children, how total number of children??
i've created variable know sub-menu item i'm on within end_el function:
class custom_nav_walker extends walker_nav_menu { function __construct() { $this->boxitem_index = 0; } public function start_lvl(&$output, $depth = 0, $args = array()) { if ($depth === 0 && $this->menu_type == 'header') { echo '<pre>', var_dump($item), '</pre>'; } } } i have set custom property called menu_type gets set within start_el function attaches last menu here, i'm able know it's menu want.
basically, need split in half, not 3, i'm not able know half is. , ofcourse, don't want perform if statement on last item. so, know how many items have $depth === 1 last parent menu. possible?
the output $item this:
object(wp_post)#723 (40) { ["id"]=> int(73) ["post_author"]=> string(1) "1" ["post_date"]=> string(19) "2016-07-14 18:09:44" ["post_date_gmt"]=> string(19) "2016-07-14 18:09:44" ["post_content"]=> string(0) "" ["post_title"]=> string(11) "quick links" ["post_excerpt"]=> string(0) "" ["post_status"]=> string(7) "publish" ["comment_status"]=> string(6) "closed" ["ping_status"]=> string(6) "closed" ["post_password"]=> string(0) "" ["post_name"]=> string(13) "quick-links-3" ["to_ping"]=> string(0) "" ["pinged"]=> string(0) "" ["post_modified"]=> string(19) "2016-07-21 17:12:08" ["post_modified_gmt"]=> string(19) "2016-07-21 17:12:08" ["post_content_filtered"]=> string(0) "" ["post_parent"]=> int(0) ["guid"]=> string(30) "http://0b90b21a.ngrok.io/?p=73" ["menu_order"]=> int(12) ["post_type"]=> string(13) "nav_menu_item" ["post_mime_type"]=> string(0) "" ["comment_count"]=> string(1) "0" ["filter"]=> string(3) "raw" ["db_id"]=> int(73) ["menu_item_parent"]=> string(1) "0" ["object_id"]=> string(2) "73" ["object"]=> string(6) "custom" ["type"]=> string(6) "custom" ["type_label"]=> string(11) "custom link" ["title"]=> string(11) "quick links" ["url"]=> string(0) "" ["target"]=> string(0) "" ["attr_title"]=> string(0) "" ["description"]=> string(0) "" ["classes"]=> array(5) { [0]=> string(0) "" [1]=> string(9) "menu-item" [2]=> string(21) "menu-item-type-custom" [3]=> string(23) "menu-item-object-custom" [4]=> string(22) "menu-item-has-children" } ["xfn"]=> string(0) "" ["current"]=> bool(false) ["current_item_ancestor"]=> bool(false) ["current_item_parent"]=> bool(false) }
you can use filter function 2 additional properties _children_count , _parent_children_count on each item, can later evaluate in menu walker:
function my_wp_nav_menu_objects_filter($sorted_menu_items) { foreach($sorted_menu_items &$item) { $item->_children_count = 0; for($i=1, $l=count($sorted_menu_items); $i<=$l; ++$i) { if($sorted_menu_items[$i]->menu_item_parent == $item->id) { $item->_children_count++; } } } foreach($sorted_menu_items &$item) { $item->_parent_children_count = 0; for($i=1, $l=count($sorted_menu_items); $i<=$l; ++$i) { if($item->menu_item_parent == $sorted_menu_items[$i]->id) { $item->_parent_children_count = $sorted_menu_items[$i]->_children_count; break; } } } unset($item); return $sorted_menu_items; } add_filter('wp_nav_menu_objects', 'my_wp_nav_menu_objects_filter' ); weirdly enough, looks $sorted_menu_items array numerically indexed starting @ 1.
added _ in front of new properties pseudo-namespacing, avoid collisions possible future official properties.
