I did same error first time I implemented WP_List_Table. The problem is that when you call WP_List_Table::display() WordPress in turn calls: WP_List_Table::display_rows_or_placeholder() WP_List_Table::display_rows() WP_List_Table::single_row() WP_List_Table::single_row_columns() Last function is called for every row. If you look at its code (see source), it has: if ( ‘cb’ == $column_name ) { // you don’t have ‘cb’ column, … Read more
As the last commenter on that Q suggested, you should probably check for actions, remove the query args and redirect. Something like: $doaction = $wp_list_table->current_action(); if ( $doaction && isset( $_REQUEST[‘SOMEVAR’] ) ) { // do stuff } elseif ( ! empty( $_GET[‘_wp_http_referer’] ) ) { wp_redirect( remove_query_arg( array( ‘_wp_http_referer’, ‘_wpnonce’ ), stripslashes( $_SERVER[‘REQUEST_URI’] ) … Read more
Nice solution you have there. But you must define a $screen property inside WP_List_Table class (or its child class) before pagination method is invoked. You want to make the $screen property as WP_Screen instance using this function : $this->screen = get_current_screen(); There you go, and your table is ready to go. Thanks
I just run in the same error when adding extra columns to the default post types. The offending line was the $pagenow check. Quick Edit uses admin-ajax.php so it doesn’t renders the custom columns when it’s done. This doesn’t work: if( ‘edit.php’ == $pagenow && is_admin() ) { add_action( ‘admin_init’, array( $this, ‘init_id_column’ ), 999 … Read more
In the parent __construct args if ajax is set to true the js_vars will be output in the footer of the page. /** * Constructor. The child class should call this constructor from it’s own constructor * * @param array $args An associative array with information about the current table * @access protected */ function … Read more
There is currently a trac ticket on the fact that taxonomy counts are global (include all post types). Related trac ticket. To fix this you can remove the column and add your own using the manage_edit-{$taxonomy}_columns filter: add_filter(‘manage_edit-season_columns’,’my_season_columns’); function my_season_columns($columns){ unset($columns[‘posts’]); $columns[‘cpt_count’] = ‘Races’; return $columns; } You then tell WordPress what to fill this … Read more
An ‘easy’ but not very good solution is to store the user’s display name as well as ID, and sort by that. Obviously an update of a user’s display name would prompt an update of all the domicile that user owns. Alternatively the following is an outline (untested) of what should work. The idea is … Read more
Your problem is a simple typo: array($this, ‘manage_post_columns’, 10, 2) VS. array($this, ‘manage_post_columns’), 10, 2 I guess you see the difference
If you add a bulk-action, then you have to react on this action. Simply adding a function doesn’t do anything, you have to call it: class WPSE_List_Table extends WP_List_Table { public function __construct() { parent::__construct( array( ‘singular’ => ‘singular_form’, ‘plural’ => ‘plural_form’, ‘ajax’ => false ) ); } public function prepare_items() { $columns = $this->get_columns(); … Read more
To achieve adding a custom sortable column to the WP_List_Table of your post type within the WordPress administration back-end dashboard, you will need to do the following: Replace all occurrences of YOUR-POST-TYPE-NAME with your actual post type name. Replace all occurrences of YOUR-TAXONOMY-NAME with your actual taxonomy name. Replace all occurrences of YOUR COLUMN NAME … Read more
