I've reported this as a double post of your other thread, since the two are closely related.

Also, as per the LQ rules, please write out your words in full.

Always check for errors after mysql_query:

Code:

$result= mysql_query ($stmt);
if ($result===FALSE) {
    printf ("<H1>Error in '%s': '%s'</H1>\n",
    htmlspecialchars ($stmt),
    htmlspecialchars (mysql_error ()));
    exit (1);
}

shygvy, please post the same question in one thread only. As Nylex pointed out, you posted the same question as a followup in your original thread. It's okay to do either, just not both.
