Use wp_get_nav_menus() instead of get_terms('nav_menu') in WP_Nav_Menu_Widget

[anonymized_8769252]

The wp_get_nav_menus() function has a wp_get_nav_menus filter that allows you to filter the array of menu objects returned by the function.

The WP_Nav_Menu_Widget class however uses a direct call to get_terms('nav_menu') to render the widget form. As such, the wp_get_nav_menus filter is not applied to the menus available on the widget configuration screen.

The attached patch fixes this by using the wp_get_nav_menus() function.

This should probably be wp_get_nav_menus( array( 'orderby' => 'name' ) ) to keep the current ordering (unlike get_terms(), wp_get_nav_menus() uses 'none' by default).

Thanks, I updated the patch accordingly.

Tested 25263.patch​ by filtering on the wp_get_nav_menus hook before and after.

Works for me.

In 25332:

Use wp_get_nav_menus() instead of get_terms('nav_menu') in WP_Nav_Menu_Widget to preserve use of `wp_get_nav_menus' filter.

Props Frank Klein.
