Check sql match query

I have a wordpress post title $title = 'my post title';

I have a table called interlinks where I store all my post titles, urls, and siteurls or my entire network.

This query matches my title with all the titles in the interlinks table.

Please check if my query is correct. Thank you. I have a feeling it's a big buggy.

$query_related_posts_network = mysql_query(
   "SELECT "
   "   posttitle, "
   "   posturl, "
   "   siteurl, "
   "   MATCH (posttitle,posturl,siteurl) AGAINST ('$titl开发者_JAVA技巧e') AS score "
   "FROM "
   "   interlinks "
   "WHERE "
   "   MATCH (posttitle,posturl,siteurl) AGAINST ('$title') AND "
   "   `siteurl` <> '$blogurl' "
   "LIMIT 15");

The only thing I can see is:

Don't forget to escape the string variables you put in your SQL queries, using mysql_real_escape_string().

$query_related_posts_network = mysql_query("SELECT posttitle, posturl, siteurl,
  MATCH (posttitle,posturl,siteurl) AGAINST ('".mysql_real_escape_string($title)."') AS score
  FROM interlinks
  WHERE MATCH (posttitle,posturl,siteurl) AGAINST ('".mysql_real_escape_string($title)."')
    AND `siteurl` <> '".mysql_real_escape_string($blogurl)."' LIMIT 15");
