Looking to display the time at which media has been attached/uploaded to your WordPress library along with the date?
Add the following in your child theme’s functions.php:
add_filter( 'manage_media_columns', 'sk_media_columns_time' );
/**
* Filter the Media list table columns to add a Time column.
*
* @param array $posts_columns Existing array of columns displayed in the Media list table.
* @return array Amended array of columns to be displayed in the Media list table.
*/
function sk_media_columns_time( $posts_columns ) {
$posts_columns['time'] = _x( 'Time', 'column name' );
return $posts_columns;
}
add_action( 'manage_media_custom_column', 'sk_media_custom_column_time' );
/**
* Display attachment uploaded time under `Time` custom column in the Media list table.
*
* @param string $column_name Name of the custom column.
*/
function sk_media_custom_column_time( $column_name ) {
if ( 'time' !== $column_name ) {
return;
}
the_time( 'g:i:s a' ); // in hh:mm:ss am/pm format.
}
add_action( 'admin_print_styles-upload.php', 'sk_time_column_css' );
/**
* Add custom CSS on Media Library page in WP admin
*/
function sk_time_column_css() {
echo '<style>
.fixed .column-time {
width: 10%;
}
</style>';
}
The time shown will be in the timezone set in WordPress settings. The default is UTC+0.
If you would like to display the time in the format set in WordPress, replace the_time( 'g:i:s a' )
with the_time()
.
Additionally, to make the Time column sortable add:
add_filter( 'manage_upload_sortable_columns', 'sk_sortable_time_column' );
/**
* Register Time column as sortable in the Media list table.
*
* @param array $columns Existing array of columns.
*/
function sk_sortable_time_column( $columns ) {
$columns['time'] = 'time';
return $columns;
}
