// Date format used as the prefix.
$wpide_upload_date_format = 'Y-m-d';
add_filter( 'wp_handle_upload_prefilter', function ( $file ) use ( $wpide_upload_date_format ) {
if ( preg_match( '/^\d{4}-?\d{2}-?\d{2}/', $file['name'] ) ) {
return $file;
}
$file['name'] = wp_date( $wpide_upload_date_format ) . '-' . $file['name'];
