New post type undefined delete post value

[ozzWANTED]

I have WP_DEBUG = TRUE on my localhost.

I registered new post type for my plugin. And then went to WP ADMIN -> MENU -> CARS. And in the list of 'cars' (no items added) I see this warning:
Notice: Undefined property: stdClass::$delete_posts in C:\Program Files (x86)\Zend\Apache2\htdocs\GitHub\*WEBSITE-NAME*\wp-admin\includes\class-wp-posts-list-table.php on line 209

Hi ozzWANTED,

Can you provide your post type registration code so we can attempt to reproduce your issue?

[SergeyBiryukov]

I can reproduce with 'map_meta_cap' => false. Introduced in [29757].

The ​Codex page says: "There are also seven other primitive capabilities which are not referenced directly in core, except in map_meta_cap()..."

That is no longer true since [29757].

Hi ozzWANTED,

Here you go my friend:

function crs_custom_post_type_init()
{
	$menu_position1 = 95;
	$icon_url = plugins_url().'/car-rental-system/images/plugin.ico';

	// Set UI labels for Custom Post Type
	$labels = array(

@ozzWANTED Have you setup the delete_posts and other custom capabilities for car somewhere else in your code, since you have 'capability_type' => 'car' in your arguments array?

Probably I don't setup that anywhere else. Should I? Can you give of example code so that I could do 'search' in my PhpStorm project. But my first guess that there is no other definition for it. I thought it was the place to define it.

[valendesigns]

This is a question for the forums and is beyond the scope of Trac. Short answer, set it to post until you find the answer you're looking for on adding custom capabilities. I'm closing this as worksforme, because everything works when you have capability_type set to post. Cheers!

[ozzWANTED]

Well, it still doesn't work if I do set map_meta_cap to false, trying to hide add/edit buttons

'capability_type'     => 'post',
'map_meta_cap'        => false, // Set to false, if users are not allowed to edit/delete existing posts

Erorr:

Notice: Undefined property: stdClass::$delete_posts in C:\Program Files (x86)\Zend\Apache2
\htdocs\GitHub\**WEB***\wp-admin\includes\class-wp-posts-list-table.php on line 209

@ozzWANTED This is still working correctly in Core, what is not working correctly is your combination of arguments. Unless you are planning on creating your own custom meta capabilities setting map_meta_cap to false is essentially removing all the post capabilities. Therefore, you either need to set map_meta_cap to true or roll out your own capabilities.

Well, it doesn't work even then. If I map these capiblities, still gives me the same error.

This code gives an error:

		'capability_type'     => 'car',
		'map_meta_cap'        => false, // Set to false, if users are not allowed to edit/delete existing posts
		'capabilities' => array(
			'read'
		),

This code also gives an error:

		'capability_type'     => 'post',
		'map_meta_cap'        => false, // Set to false, if users are not allowed to edit/delete existing posts
		'capabilities' => array(
			'read'
		),

This was a regression introduced in [29757], see comment:2.

We need to decide what the correct fix is, please don't close as worksforme.

Sorry about that. The code above looked like it was the cause of the issue for this particular situation and could be solved by changing it accordingly. Apologies for the confusion.

It seems like we should be fixing the regression in the original ticket that introduced it or is that not the process?

Duplicate of #30991.

There's already a ticket and patch for this issue.
