I'm trying to display a WP_List_table inside a metabox. The metabox is for listing registered users to a course(LifterLMS Course Post Type). The table columns contain user_id, user_name, percentage & grades. I don't think the fact that I'm trying to this for a custom post type. I only merely mention to for clarity sake.
What's happening is that it all looks fine until I click the Search By Id( used wp search button function ) button on the custom post type edit screen. WP_List_Table will redirect back to the /wp-admin/edit.php page on clicking the search button ( after entering ID in input element). And it shows an admin notice of post updated on top of edit screen. What it should do , is to list only that user for which admin has searched. Same code i used on other admin menu pages worked fine. All other functions are working fine ( Ascending order, Descending order, order_by ). Only issue arises with search functionality. Code is attached below. data
/** Class constructor */
public function __construct() {
parent::__construct( [
'singular' => __( 'Student', WOOSUB_TEXT_DOMAIN ), //singular name of the listed records
'plural' => __( 'Students', WOOSUB_TEXT_DOMAIN ), //plural name of the listed records
'ajax' => false //does this table support ajax?
] );
