Can WordPress batch delete photos in media by name?

You can achieve it by using below script.

Please make sure before running this script take a database & full site backup.

Script

global $wpdb;

$filename_pattern = 'loc_va_phu_tung'; //pattern of the file/media which you want to delete.
$lastmedia_id = get_option('wh_last_checked_media_id', 0); //flag to detect the last media that was deleted.
$limit = 20; //number if files that you want to delete per request

/**
 * Get list of all pending image to delete
 *
 * @global $wpdb
 * @param int $lastmedia_id last media ID
 * @param string $filename_pattern file pattern
 * @param int $limit number of files that you want to delete
 * @return array
 */
function wh_get_image_list($lastmedia_id, $filename_pattern, $limit) {
    global $wpdb;
    return $wpdb->get_results($wpdb->prepare('SELECT `ID`, `post_date`, `post_title`, `post_excerpt`, `post_status`, `post_name`, `post_parent`, `guid`, `post_type`, `post_mime_type`
                                               FROM `' . $wpdb->prefix . 'posts`
                                                WHERE `post_name` LIKE %s
                                                AND `post_type` = %s
                                                AND `ID` > %d
                                               LIMIT  %d', '%' . $filename_pattern . '%', 'attachment', $lastmedia_id, $limit), OBJECT);
}

$data = wh_get_image_list($lastmedia_id, $filename_pattern, $limit);
print_r($wpdb->last_query, 1); //To check the query which was executed.

if (!empty($data)) {
    foreach ($data as $media) {
        print_r($media, 1, 'del');

        # Uncomment below line if you want to delete the media permanently
        # Once the file is deleted you will not be able to restore it unless you have a backup.
        # wp_delete_attachment($media->ID, true);
    }

    update_option('wh_last_checked_media_id', $media->ID, false);
}

How to use it

You can create a custom template and put the above code. Then create a page using newly created template then visit the URL. It will display the list of media that is deleted. You can also setup a CRON which will do the stuff in the background.

The code is tested, and fully functional.
