wp-o-matic Urls

[ii silver ii]

Everytime a new feed item is added to the posts it uses the following structure:

    $postid = wp_insert_post(array(
    	'post_title' 	            => $title,
  		'post_content'  	        => $content,
  		'post_content_filtered'  	=> $content,
  		'post_category'           => $category,
  		'post_status' 	          => $status,
  		'post_author'             => $authorid,
  		'post_date'               => $date,
  		'comment_status'          => $comment_status,
  		'ping_status'             => $allowpings,
    ));

However I'm trying to add the permalink for each item, I've tried adding the url as a function parameter to pass it in but I'm having no luck..

$postid = $this->insertPost($wpdb->escape($item->get_title()), $wpdb->escape($content), $date, $categories, $campaign->posttype, $campaign->authorid, $campaign->allowpings, $campaign->comment_status, $meta, $item->get_permalink());

  function insertPost($title, $content, $timestamp = null, $category = null, $status = 'draft', $authorid = null, $allowpings = true, $comment_status = 'open', $meta = array(), $url)

$postid = wp_insert_post(array(
    	'post_title' 	            => $title,
  		'post_content'  	        => $content,
  		'post_content_filtered'  	=> $content,
  		'post_category'           => $category,
  		'post_status' 	          => $status,
  		'post_author'             => $authorid,
  		'post_date'               => $date,
  		'comment_status'          => $comment_status,
  		'ping_status'             => $allowpings,
  		'url'                         => $url
    ));

Any Ideas?
