Add an action hook to add fields to nav_menu items form

[DreadLox]

Hello,

In order to add a custom field to a nav menu item form, I have to setup a custom walker whereas a simple action hook could do the trick. Everything else is ok to handle and save the custom field. (​http://loxdev.knc.nc/blog/wordpress/auto-populate-nav-menu-with-sub-pages/)

Here is how the asked action hook could be added:

I think this should really be an alternative to the wp_edit_nav_menu_walker filter, which replaces the walker classname. This filter will cause clashes if multiple plugins change the classname of the walker. Only the last filter run will win.

This action would be a way for multiple plugins to add fields to the menu items (like is done with widget fields right now) and not have conflicts.

Is there any reason this one-line patch cannot be incorporated into 3.3 ...?

Closed #18889 as a duplicate. It had ticket18889.patch​ which suggested a large number of new filters.

Because the time for feature requests / enhancements passed a while ago.

Since this is part of a walker, those doing big customizations can replace it. We should probably solve issues like nav-menus.php saving quite a bit of data before we open this up too much. Per IRC scrub.

@nacin Any update on this?

Calling this a dupe of #18584. Patch there includes this and is more comprehensive, and has more discussion.
