Question

I have a problem with mysql inserting. When the button is clicked, mysql insert is making a doublepost. I can’t find the problem. Why is it doubleposting?

code here http://pastebin.com/z1xx3fjt

And postNewTopic.php:

<?
session_start();
mysql_connect('.com', 'user', 'pw');
mysql_select_db('db');

function msg($status,$txt){
    return '{"status":'.$status.',"txt":"'.$txt.'"}';
}

if(empty($_POST['t']) or empty($_POST['ttitle'])){
    die(msg(0,"Complete all fields!"));
}



$title = mysql_real_escape_string($_POST['ttitle']);
$desc = mysql_real_escape_string($_POST['tdesc']);
$msg = mysql_real_escape_string($_POST['t']);


mysql_query("INSERT INTO f_topics(`title`, `text`, `desc`) 
                        VALUES('$title', '$msg', '$desc')");

echo msg(1,mysql_error());
?>

Maybe your /favicon.ico is loading and causing your script to run twice.

This happens when you have rewrite rules that catch missing files and you have no /favicon.ico. First time it happened to me, it was fun!

EDIT:

Consider using HTTPfox or some other tool that tracks browser requests/responses and see how many times the page is loaded. That’s the first thing you need to look for.
