Add Custom Column in Admin Post List in WordPress

In this post I’ll show you how to add Custom Columns to WordPress Posts Management screen. Also I will show how to make those Columns Sortable.

To add Columns in Posts Page in Admin Screen, add filter “manage_posts_columns” and action “manage_posts_custom_column” in functions.php of your theme.

// register custom columns
add_filter( 'manage_posts_columns', 'custom_manage_post_column_test' );

function custom_manage_post_column_test( $columns ) {
	
    $columns['test']  = 'Test Column';
    return $columns;
	
}

// values to display in custom column
add_action( 'manage_posts_custom_column', 'custom_manage_post_column_test_data', 10, 2 );

function custom_manage_post_column_test_data( $column_name, $post_id ) {
    if( $column_name == 'test' ) {
        
        $data = 'get some data here';
        echo '<strong>' . $data . '</strong>';
    } 
}

Now your Admin screen will include a column with name “Test Column”.

To make it sortable, add below filters in functions.php of your theme.

add_filter( 'manage_edit-post_sortable_columns', 'custom_manage_post_column_test_sorting' );
function custom_manage_post_column_test_sorting( $columns ) {
  $columns['test'] = 'test';
  return $columns;
}

add_filter( 'request', 'custom_manage_post_column_test_orderby' );
function custom_manage_post_column_test_orderby( $vars ) {
    if ( isset( $vars['orderby'] ) && 'test' == $vars['orderby'] ) {
		
	// if it is some post meta variable then use this, otherwise modify query accordingly
		
        $vars = array_merge( $vars, array(
            'meta_key' => 'post_views_count',
            'orderby' => 'meta_value_num' // if text, then use meta_value instead of meta_value_num
        ) );
    }

    return $vars;
}
