$35
create a custom menu item

i have a custom menu
its ID=19

i duplicate this menu and i want to populate this new menu with the items of the first menu (id=19)

i use this code

$menu_id=19;

$menu_items = wp_get_nav_menu_items($menu_id);



$new_name "another menu";

$new_menu = wp_update_nav_menu_object( 0, array( 'menu-name' => $new_name ) );

$new_menu = wp_get_nav_menu_object($new_menu);





$new = array();



          foreach($menu_items as $menu_item) {

          

                 $new = array(

                     'menu-item-db-id' => $menu_item->db_id,

                     'menu-item-object-id' => 0,

                     'menu-item-object' => '',

                     'menu-item-parent-id' => $menu_id,

                     'menu-item-position' => $menu_item->menu_order,

                     'menu-item-type' => $menu_item->type,

                     'menu-item-title' => $menu_item->post_title,

                     'menu-item-url' => $menu_item->url,

                     'menu-item-description' => $menu_item->post_content,

                     'menu-item-attr-title' => $menu_item->post_excerpt,

                     'menu-item-target' => '',

                     'menu-item-classes' => '',

                     'menu-item-xfn' => '',

                     'menu-item-status' => 0,

                 );      

                 

              wp_update_nav_menu_item($new_menu->term_id, $menu_item_db_id = 0, $new);

          }

the result is a menu with an invalide item
Look at the attachment.

probably there is a problem inthe mapping of array $menu to array $new
but i'm tired and i don't see the error.

Thx for your help :-)

Check this line:
```
'menu-item-parent-id' => $menu->term_id,
```
Shouldn't it be
```
'menu-item-parent-id' => $menu_item->term_id,
```
?

  $menu->term_id is $menu_id in fact (=19)

Sébastien,

I think you cannot repeat in same DB the same menu-item-db-id, so:
```
'menu-item-db-id' => $menu_item->db_id
```
Should be:
```
'menu-item-db-id' => 0
```
The constructor accepts 0 (http://hitchhackerguide.com/2011/02/12/wp_update_nav_menu_item/) to give his own value.

Tell me.

  Sébastien,
  
  You should DELETE in DB all items created previously.

Sébastien | French WordpressDesigner says:
Nice.

You have changed,
'menu-item-db-id' => 0,
and
'menu-item-parent-id' => $menu_item->post_parent,

Is that correct ?

Now, there is yet a valid item.

But there are two problems :
-this item is a custom (the original item is a category)
-the status of this item is not "publish"
12/17/11 1:16pm

Kannan C says:
first thing i noticed is
```
'menu-item-title' => $menu_item->title
```
i am not sure about menu type, you can try using menu-item-type in the array (let me google for correct value for that. For publish simply include
```
'menu-item-status' => 'publish'
```
12/17/11 1:22pm

Sébastien | French WordpressDesigner says:
'menu-item-status' => 'publish' seems to work :-))

But the is a problem :
-this item is a custom (the original item is a category)

Sébastien | French WordpressDesigner says:
i have added
```
                     'menu-item-object' => $menu_item->object,

                     'menu-item-type' => $menu_item->type
```
and this problem seems resolved
but there is a big problem with the order
if i drag and drop utems, the ordre is not well saved

Kannan C says:

this is working fine for me. verified the re-order.



$new = array(

                     'menu-item-db-id' => 0,

		     'menu-item-object-id' => $menu_item->object_id,

Sébastien | French WordpressDesigner says:
Are you sur it's ok for you ?
have you test with several items (custom, category and page) ?

'menu-item-object' => $menu_item->type_label,
seems to be wrong
i replace by 'menu-item-object' => $menu_item->object,
12/17/11 2:21pm

Kannan C says:
type_label and object is both working. Go with object.
yes its saving as where it is dropped. check screenshot

Sébastien | French WordpressDesigner says:
No
in french "type_label" return "catégorie" and "object" return "category"
if i use type_label that doesn't work
12/17/11 3:10pm

Sébastien | French WordpressDesigner says:
i test the re-order in another site, a new installation of wordpress, and that doesn't work

Delete your menu and let the function create another menu.
And try to re-ordre the items : put a page between two categories
(don't place an item as a children of another item)

12/17/11 10:56pm

Kannan C says:

ok. i tested in a new installation and included a page menu btn categories, it's saved correctly. I don't know when you are duplicating the menu. But hope you do this on single action, let say on theme activation.



if ( is_admin() && isset($_GET['activated'] ) && $pagenow == 'themes.php' ) {

$menu_id=24;



$menu_items = wp_get_nav_menu_items($menu_id);

//return $menu_items;

$new_name = "another menu";



$new_menu = wp_update_nav_menu_object( 0, array( 'menu-name' => $new_name ) );



$new_menu = wp_get_nav_menu_object($new_menu);

$new = array();



  foreach($menu_items as $menu_item) {    



	 $new = array(

		 'menu-item-db-id' => 0,

		 'menu-item-object-id' => $menu_item->object_id,

		 'menu-item-object' => $menu_item->type_label,

		 'menu-item-type'  => $menu_item->type, 

		 'menu-item-parent-id' => $menu_item->post_parent,

		 'menu-item-position' => $menu_item->menu_order,

		 'menu-item-title' => $menu_item->title,

		 'menu-item-url' => $menu_item->url,

		 'menu-item-description' => $menu_item->post_content,

		 'menu-item-attr-title' => $menu_item->post_excerpt,

		 'menu-item-status' => 'publish',

		 'menu-item-target' => ''

	 );  

  wp_update_nav_menu_item($new_menu->term_id, $menu_item_db_id = 0, $new);



  }

Sébastien,

If you duplicate menu, you have to update the parent id of each menu created so the structure remain same but with the correct id.

since each menu rely on $menu_item->menu_item_parent to create the hierarchy and each time you create a new menu item, it also create new id so all should be updated.

try this

$menu_id=19;

$menu_items = wp_get_nav_menu_items($menu_id);



$new_name = "another menu";

$new_menu = wp_update_nav_menu_object( 0, array( 'menu-name' => $new_name ) );

$new_menu = wp_get_nav_menu_object($new_menu);



$new = array();

$menu_new_id = array();



foreach($menu_items as $menu_item) {



	if($menu_item->menu_item_parent != 0)

		$parent = $menu_new_id[$menu_item->menu_item_parent];

	else

		$parent = 0;

    $new = array(

            'menu-item-db-id' => 0,

            'menu-item-object-id' => $menu_item->object_id,

            'menu-item-object' => $menu_item->type_label,

            'menu-item-parent-id' => $parent,

            'menu-item-position' => $menu_item->menu_order,

            'menu-item-type' => $menu_item->type,

            'menu-item-title' => $menu_item->post_title,

            'menu-item-url' => $menu_item->url,

            'menu-item-description' => $menu_item->post_content,

            'menu-item-attr-title' => $menu_item->post_excerpt,

            'menu-item-target' => '',

            'menu-item-classes' => '',

            'menu-item-xfn' => '',

            'menu-item-status' => 0,

    );        

	$menu_new_id[$menu_item->ID] = wp_update_nav_menu_item($new_menu->term_id, 0, $new);
