Issue with admin page hierarchy in Menu admin

[hcceast]

Under Appearance > Menus in the left column under Pages, if I have more than 50 pages, the hierarchy view gets messed up. The issue seems to be related to paginate.

If I change the "50" on lines 589 and 809 of wp-admin/includes/nav_menu.php to "955" the hierarchal admin menu works with 50+ pages.

Attached are two XML files. One contains 50 pages and the other contains 53 pages. I've loaded them into fresh installs of 3.2.1 using the twenty eleven theme and no plugins.

Paginate is great if it works right, if it won't work, just increase the number per page to something very high and people can scroll. I'd rather scroll than not have hierarchy work right.

Taxonomies are also affected.

Closed #19837 and #20351 as duplicates.

[Marventus]

I suspect the $depth parameter could be failing during pagination.
I'll take a look into it see if I can find anything.

[Whissi]

Is anybody working on this? The current release (3.3.2) is still affected.

When is this ticket going to be resolved? is there a patch? This is core functionality keeping my project from launching which is over 18months old. not cool. I can put in pages manually but my client cant manage them and as it turns out they have a very deep sitemap to place in the menu's section.

so again.. when is this to be resolved?

[Marventus]

@energy0m: the issue will be resolved when... someone takes the time to resolve it. It seems Sergey is looking into it, but if you are in a rush, I suggest you contact him and - here's a crazy idea! - offer him to help. In the meantime, I can only suggest you take a chill pill and read up on what Open Source is all about: ​http://en.wikipedia.org/wiki/Open_source.

[energy0m]

How can I help him when I don't know enough about PHP to resolve the problem?

[SergeyBiryukov]

I'm not actually looking into it yet, I've just removed the previous owner so that someone else could take over this ticket. Feel free to submit a patch.

[helen]

This is essentially a visual bug - the hierarchy is not actually altered, and since nav menus specifically do not rely on the page hierarchy, nothing is broken beyond the visual. Yes, it is a bug and yes, it is frustrating, but it shouldn't be something that holds up a launch.

[allergicvegetarian]

This issue also effects categories as well, when you are creating a menu. I'm making a navigation menu that isn't on a specific page.

Obviously, this isn't going to get fixed soon, given a computer programmers time for open source projects is directly related to the amount of extra work their real job requires them to program "for free" under the heading of "salaried" (work 60 hours, get paid for 40). LOL I fully support the Computer Programmer in this, and in no way, am I dissing the programmer. I'm also against such abuse of programmers.

Patch to work around nav menu pagination

[Aries-Belgium]

The issue is indeed the pagination that breaks the hierarchy of the pages. It's possible that some child pages aren't on the same page/section than the parent page which confuses the Walker.

In the attachment a patch for a quick workaround by disabling the pagination for the "All"-tab. When I find the time I will see if I can come up with a solution where the pagination doesn't break the hierarchy but for now this patch also works.

Is there a reason why this was never fixed?
Why is there a plugin to fix a core functionality?
What are the steps one should take to get this issue to be fixed?

Thanks!

[majemedia]

For larger sites that have a massive number of pages this is causing issues. The steps in the original description properly duplicate this.

The plugin by @SergeyBiryukov works as designed, but when you're dealing with a large number of pages (> 500) the nav menu page takes a long time.

The patch by @Aries-Belgium run into the same load time issues.

[sjlevy]

I can confirm that this is still an issue with 4.5.2

@SergeyBiryukov 's plugin works by eliminating pagination under 'View All'

[xavierserranoa]

i have been looking into this. the only solution i could present for this scenerio is to have the walker or the query results $post variable be handled the same way it is handled by class-wp-posts-list-table look at _display_rows_hierarchical and _page_rows. this way the displaying of the posts will work with pagination. still kind of testing it out and seeing what could be done would love help or pointers if anyone has any.

Hi,
Is there a reason why this was never fixed?

This bug is also affecting Woocommerce in a Bad way.

As you can see at the ticket https://core.trac.wordpress.org/ticket/40827 and the ticket at Woocommerce at ​https://github.com/woocommerce/woocommerce/issues/13040 Woocommerce devs did comment saying this bug is affecting Woocommerce too.

Would be nice to have a real fix and a fix that would work with Woocommerce.

[torndownunits]

I can't believe this is still an issue, but thank you @SergeyBiryukov for the fix. as @raykaii said, it's a complete pain with WooCommerce.

@torndownunits did the temp fix work for WC ? it's not working for me.

[torndownunits]

Replying to raykaii:

Yes, I used the plugin from post #25. It's not ideal but it makes the Product Categories hierarchy at least display correctly in Appearance--> Menus (using View All) which is what I needed. It was a mess before, and now the hierarchy of everything is at least correct. Using the editor with dozens (never mind hundreds) of items is a pain still, but I can use it. Also, I ended up here from your posts at Woo. But isn't this a problem with all items in the Menu editor, not just Woo items? The editor basically is just horrible when dealing with dozens (never mind hundreds) of options in general.

Make a folder inside your plugins folder. Put the file in it. Go into your dashboard, go to plugins, activate it. You will see it listed in your plugins.

I didn't see them say they'd fix anything? They said it's a problem with Wordpress, which it is. It's not specifically a problem with Woo taxonomies, it's a problem with all taxonomies. It's not really their problem to fix.

AND.... DOWNLOAD the file above ... DO NOT copy/paste the code into a text file, saved it, uploaded it, and it didn't work.

HOWEVER ... when I Select All and add (Product Categories) it doesn't add them all ... 130 out of 241 menus.

[danburzo]

I found a somewhat simpler (more targeted) solution to disable pagination in these meta boxes, by placing a filter on the nav_menu_meta_box_object hook:

<?php
  add_filter( 'nav_menu_meta_box_object', array( $this, 'disable_pagination_in_menu_meta_box' ) );

  function disable_pagination_in_menu_meta_box($obj) {
    $obj->_default_query = array(
      'posts_per_page' => -1
    );
    return $obj;
  }
?>

Please be advised that this uses the private-looking _default_query, so your mileage may vary, but it worked very well for me.

[danburzo]

Update: Needs to be added with priority 9 to work well with the default filter _wp_nav_menu_meta_box_object. Corrected line below:

<?php
add_filter( 'nav_menu_meta_box_object', 'disable_pagination_in_menu_meta_box', 9 );

I am not sure how many it's working with successfully on my site, but it's not as many as you are trying it with for sure. I am going to try out the solution just added by @danburzo as well. See if one works better than the other.

[lnedo]

I just wanted to add an update that I am also experiencing this issue and my site has nowhere near 500 pages. I have 71 total pages. This is a site for a school, so I have many pages added as children of a main "Schools" page. The fact that the parent starts with an 'S' causes the majority of the children to appear as top-level items when pagination is enabled (not in alpha order, either.)

Adding the filter @danburzo suggested worked perfectly.

[damtii]

Hi,
I am having similar issue on my site when using woocommerce.
I am having around 150 categories and I can't see the product category hierarchy right.

any fix for that?

thanks.

[Baroninn]

I had the same issue,
Tried all kinds of solutions.
The one that worked for me was to download this plugin and activate
https://core.trac.wordpress.org/attachment/ticket/18282/preserve-page-and-taxonomy-hierarchy.php

You can see the download button at the bottom of the page.
You then need to create a folder in your plugins folder and place this file in there.
Everything was perfect for me after that.

[helpadrian]

Hello

i am using the plugin > preserve page and taxonomy hierarchy. It works well (thanks), but all of a sudden it is not giving me all the product categories i have created (not listing all of them in the add to menu section under view all).. there is alot, over 900 product categories and counting... Please help as i cant seem to find a work around. It will be impossible for me(ie take to long so i wont do it) to add those many items to the menu in their respective sub categories.

I have also tried @danburzo advice but unfortunately it did not work for me.

Please help

[flyingkites]

While this issue relates to WordPress, my interest is with WooCommerce.

For WooCommerce users who have a large number of Product Categories, the patch provided by @SergeyBiryukov will stop working after a certain number.

The patch essentially removes pagination. However once you get "too many" categories you may end up with a blank nav-pages.php page without any error showing in site error logs. Your only option is to then remove the patch. (If I eventually find server settings that will allow it to run I will repost but our test show it fails around 2500 categories).

It is naive of @helen to say that this fundamental defect in WordPress should not stop a site going live. Being able to create specific menus for ecommerce is a must in order to provide customers with a unique customer experience. If you have over 2000 categories, many with duplicate names as happens on many eCommerce sites, you cannot distinguish category names if the category list does not show the hierarchy. Being able to see the hierarchy in a paginated view is a must.

It would be good if the WP team took the issue seriously.

Great thanks to @SergeyBiryukov for the patch preserve-page-and-taxonomy-hierarchy.php

It works well and keeps the hierarchy of all my 83 woocommerce product categories when trying to add them to a menu.

Unfortunately in the Appearance--> Menus (using View All) there are all the product categories being re-sorted alphabeticaly! Is it possible to keep the original sorting order of the product categories as well, together with keeping the hierarchy?

Thanks!

This plugin/patch still works as of WordPress 6.1. However, how is this issue still a thing in 2023? This is just bad UX and causes confusion when building menus. Been chasing this down for a week before finally stumbling on this and luckily the plugin works to where I can feel confident with handing over a project to a client.
