Add per_page filter to nav-menu.php

[Martin Snajdr]

Right now there is a hardcoded number of posts / terms (50) displayed per page in wp-admin/includes/nav-menu.php, which might be ok for posts, but it's a nightmare when having a lot of terms (hierarchical). For example in WooCommerce, I have like 200 categories and some of those are having the same name (but different parent). When I go through the list of those categories, it's quite hard to find exactly the one I'm looking for if the parent is on previous page.

Having pagination as default is ok, but there should be a simple filter that will allow plugins / themes to change the per_page variable value (at least in wp_nav_menu_item_taxonomy_meta_box), so you could list more than 50 terms per page.

Hi, thanks for the the ticket and thaks @manishamakhija for the patch. Looks good on my side.
Moving this one for 5.3 consideration.

Hi and thanks for the patch,

There is a coding standard issue in the current patch. Refreshing.

Add nav_menu_metabox_per_page_number filter to allow developers to filter $per_page variable

[audrasjb]

In 47555.1.diff:

• Add inline documentation for nav_menu_metabox_per_page_number filter.
• Use absint() function to ensure to get a proper integer.

Adding 2nd-opinion keyword to get a second opinion on that.
Adding needs-dev-note keyword: if this patch is released, the new filter would maybe deserve a dev-note (but not sure if we need it since this is a very small enhancement).

Implementation example:

function worg_per_page_number( $per_page ) {
    return 10;
}
add_filter( 'nav_menu_metabox_per_page_number', 'worg_per_page_number', 10, 3 );

Right now there is a hardcoded number of posts / terms (50) displayed per page in wp-admin/includes/nav-menu.php

FWIW, this value is already filterable via get_terms_args, see an example in #18282:
https://core.trac.wordpress.org/attachment/ticket/18282/preserve-page-and-taxonomy-hierarchy.php

A dedicated filter might still be helpful though.

I think a dedicated filter is fine here.

With version 5.3 Beta 1 landing shortly, this is being moved to Future Release.
