How to Add a “Last Modified” Column in WordPress

Snippets by IsItWP

Are you looking for a way to add a “last modified” column in WordPress post editor? While there’s probably a plugin for this, we have created a quick code snippet that you can use to add a “last modified” column in WordPress.


All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:

// Register the column
function modified_column_register( $columns ) {
	$columns['modified_list'] = __( 'Modified', 'my-plugin' );
	return $columns;
add_filter( 'manage_edit-post_columns', 'modified_column_register' );

// Display the column content
function modified_column_display( $column_name, $post_id ) {
	if ( 'modified_list' != $column_name )
	echo the_modified_date();
add_action( 'manage_posts_custom_column', 'modified_column_display', 10, 2 );

// Register the column as sortable
function modified_column_register_sortable( $columns ) {
	$columns['modified_list'] = 'modified_list';
	return $columns;
add_filter( 'manage_edit-post_sortable_columns', 'modified_column_register_sortable' );
