Undefined pp_get_groups() error

@xavierserranoa Make sure that call is within a function that’s hooked to the ‘plugins_loaded’ or ‘init’ action, not executing immediately when your code module loads.

@kevinb its performed within the ‘admin_init’ hook

@kevinb anymore info as to what else could be happening?

we are using namespaces is that maybe why?

Hi @xavierserranoa

Sorry, we don’t normally send our developers to help with custom code here on www.remarpro.com. Support for custom code is normally for our Pro members.

I will ask Kevin to circle back, but it may be next week at the earliest.

Does the error still occur if you call this instead – passing the same arguments as to pp_groups()?

\PublishPress\Permissions\API::getGroups()

@kevinb yes the issue does persist although a bit different

Fatal error: Uncaught Error: Class 'PublishPress\Permissions\API' not found in

@xavierserranoa Yes, if your code is truly executing on the admin_init action, that code module should be loaded already. But if something has gone wrong, you can load it manually right before your function call:

require_once(PRESSPERMIT_ABSPATH . '/library/api-legacy.php');

@kevinb the issue still appears as such

Fatal error: Uncaught Error: Class 'PublishPress\Permissions\API' not found in /code/wp-content/plugins/press-permit-core/library/api-legacy.php:95 Stack trace: #0 /code/wp-content/themes/crate/inc/filters.php(124): pp_get_groups('pp_group', Array) #1 /code/wp-includes/class-wp-hook.php(307): CShop\Crate\add_custom_group_caps('') #2 /code/wp-includes/class-wp-hook.php(331): WP_Hook->apply_filters(NULL, Array) #3 /code/wp-includes/plugin.php(476): WP_Hook->do_action(Array) #4 /code/wp-admin/admin.php(175): do_action('admin_init') #5 /code/wp-admin/customize.php(13): require_once('/code/wp-admin/...') #6 {main} thrown in /code/wp-content/plugins/press-permit-core/library/api-legacy.php on line 95

keep in mind this issue happens when trying to access the customizer in wordpress admin. so something in your code is causing the plugin to not load correctly when on the customizer. I dont think its the code we are using.

@xavierserranoa What Permissions version are you running?

@xavierserranoa

The stack trace shows this is related to your custom code. Please add this statement before your function call:

require_once(PRESSPERMIT_CLASSPATH . ‘/API.php’);

@kevinb it is now throwing this

Warning: Use of undefined constant PRESSPERMIT_READ_PUBLIC_CAP - assumed 'PRESSPERMIT_READ_PUBLIC_CAP' (this will throw an Error in a future version of PHP) in /code/wp-content/plugins/press-permit-core/classes/PublishPress/Permissions/Roles.php on line 21 Fatal error: Uncaught Error: Call to a member function filteringEnabled() on null in /code/wp-content/plugins/press-permit-core/classes/PublishPress/Permissions.php:427 Stack trace: #0 /code/wp-content/plugins/press-permit-core/classes/PublishPress/PermissionsHooks.php(425): PublishPress\Permissions->filteringEnabled() #1 /code/wp-content/plugins/press-permit-core/classes/PublishPress/PermissionsHooks.php(339): PublishPress\PermissionsHooks->loadContentFilters() #2 /code/wp-content/plugins/press-permit-core/classes/PublishPress/PermissionsHooks.php(281): PublishPress\PermissionsHooks->loadInitFilters() #3 /code/wp-content/plugins/press-permit-core/classes/PublishPress/PermissionsHooks.php(157): PublishPress\PermissionsHooks->actInitUser() #4 /code/wp-content/plugins/press-permit-core/classes/PublishPress/PermissionsHooks.php(112): PublishPress\PermissionsHooks->actSetCurrentUser() #5 /code/wp-content/plugins/press-permit-core/classes/PublishPress/PermissionsHooks.php(32): PublishPress\PermissionsHooks->loadFilters() #6 /c in /code/wp-content/plugins/press-permit-core/classes/PublishPress/Permissions.php on line 427

you should be able to replicate this issue by using this

/**
 * Modify custom permission group user capabilities
 */
function add_custom_group_caps() {
	require_once(PRESSPERMIT_CLASSPATH . '/API.php');
	require_once(PRESSPERMIT_ABSPATH . '/library/api-legacy.php');
	// Allow anyone assigned to a custom group the cap to upload files
	$groups = pp_get_groups(
		'pp_group',
		array(
			'cols'            => 'id',
			'skip_meta_types' => array( 'wp_role' ),
		)
	);
	foreach ( $groups as $group ) {
		$custom_group_users = pp_get_group_members( $group->id, 'pp_group', 'id' );
		foreach ( $custom_group_users as $user_id ) {
			$user = new \WP_User( $user_id );
			$user->add_cap( 'upload_files' );
			$user->add_cap( 'list_others_unattached_files' );
			$user->add_cap( 'pp_list_all_files' );
		}
	}
}
add_action( 'admin_init', __NAMESPACE__ . '\add_custom_group_caps' );

then go to the customizer and you’ll see the error.

version is 3.7.8

@xavierserranoa Thanks. We really are a long way beyond the normal level of support we offer here for custom code on www.remarpro.com.
