Hi there,

I have an ajax request on my page. I have a select form element on my page, named sz1, the ossz text input's value should be altered.

1. $(document).ready(function () {
2. $('[name="sz1"]').change(function () {
3.         var szolgjs = $(this).val();
4.         var dataString = 'szolgjs=' + szolgjs;
5.         $.ajax({
6.             type: "POST",
7.             url: "urlapar.php",
8.             data: dataString,
9.             cache: false,
10.             success: function (html)
11.             {
12.                 $('[name="ossz"]').val(html);
13.             }
14.         });
15. });
16. });

The urlapar.php:

1. <?php
2. include("connect.php");
3. if($_POST['szolgjs']) {
4.     $szolg = $_POST['szolgjs'];
5.     $szquery = "SELECT ar FROM szolgaltatasok WHERE szolgaltatas = '$szolg'";
6.     $szsql = mysql_query($szquery) or die(mysql_error());
7.     $szkiiras =  mysql_fetch_array($szsql,MYSQL_ASSOC);
8.     echo $szkiiras['ar'];
9. }
10. ?>

The joke is that I have another ajax request on the page, which is almost the same, and it's working well. I supposed that the two ajax request might interfere, so I deleted the one which was working, the other was still not working. I noticed that in fact ajax affects the ossz text field, but it's deleting the value which is written there, so I think it's returning null. Thus I have tested my SQL query, and echoed it on the original page, it was working flawlessly. So I have no idea, please help.
Thank you in advance!
