не добавляется миниатюра

не добавляется миниатюра к посту, хотя сам пост создается

                         $my_post = array(
				 'post_title' => $fam.' '.$name.' '.$surname,
				 'post_content' => 'Я использую карту скидок "'.$postcont.'"',
				 'post_status' => 'publish',
				 'post_author' => $user->ID,
				 'post_category' => array(108)
			  );
				$post_id = wp_insert_post($my_post);

$image_url        = 'http://s.wordpress.org/style/images/wp-header-logo.png'; // Define the image URL here
$image_name       = 'wp-header-logo.png';
$upload_dir       = wp_upload_dir(); // Set upload folder
$image_data       = file_get_contents($image_url); // Get image data
$unique_file_name = wp_unique_filename( $upload_dir['path'], $image_name ); 
$filename         = basename( $unique_file_name ); // Create image file name
if( wp_mkdir_p( $upload_dir['path'] ) ) {
$file = $upload_dir['path'] . '/' . $filename;
} else {
$file = $upload_dir['basedir'] . '/' . $filename;
}
file_put_contents( $file, $image_data );
$wp_filetype = wp_check_filetype( $filename, null );

// Set attachment data
$attachment = array(
'post_mime_type' => $wp_filetype['type'],
'post_title'     => sanitize_file_name( $filename ),
'post_content'   => '',
'post_status'    => 'inherit'
			);
$attach_id = wp_insert_attachment( $attachment, $file, $post_id );
require_once(ABSPATH . 'wp-admin/includes/image.php');
$attach_data = wp_generate_attachment_metadata( $attach_id, $file );
wp_update_attachment_metadata( $attach_id, $attach_data );
set_post_thumbnail( $post_id, $attach_id );

В чем мб проблема???
