lastinsertid

Hi all,

I'm trying to retrieve the id of the last record inserted in the table 'authors' and insert the retrieved id in the 'articles' table; here's my code:

$title = mysql_real_escape_string($_POST[title]);
$body = mysql_real_escape_string($_POST[body]);
$category = mysql_real_escape_string($_POST[category]);

$insert_author="INSERT INTO authors (name) VALUES ('$title')";
$select_author= mysql_query("SELECT LAST_INSERT_ID()");

$authId = mysql_fetch_array($select_author);
$query="INSERT INTO articles (body, date, category, auth_id) VALUES ('$body', '$date_now', '$category', '$authId')";

this doesn't work...

Any idea please?

Thanks in Advance

Mauro
