A problem with using Smarty & Mysql & Jquery

Question

Hi all ..

I have a problem in using Samrtm Mysql and Jquery or Ajax and if I use a div auto reloader it shows a php error .. these are my files: accept.html (Template)

{literal}
<script type="text/javascript">
var auto_refresh = setInterval(
function ()
{
$('#invite').load('accept.php').fadeIn("slow");
}, 1000);
</script>
{/literal}
<div id="invite">
<fieldset>
<legend>Invites</legend>
{section name=ct loop=$invites}
You have an invite {$sender.user}<br />
<a href="?action=accept_contest&sid={$invites[ct].sendid}">Accept</a> | <a href="?action=cancel_contest&sid={$invites[ct].sendid}">Cancel</a>
{/section}
</fieldset>
</div>

accept.php (Main file)

<?php

$time = date("i:s",time("s"));
$sql_select_invite = mysql_query("SELECT * FROM invite WHERE recid = '$_SESSION[id]' AND accept = '0' AND endtime > '$time'");

while($invite = mysql_fetch_array($sql_select_invite)){
 $sender = mysql_fetch_array(mysql_query("SELECT * FROM member WHERE id = '$invite[sendid]'"));
    $contest->assign("sender", $sender);
    $invites[] = $invite;
}
$contest->assign("invites", $invites);

?>

and when I use the Jquery thing or Ajax it shows this error:

Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in C:\AppServ\www\somefo\accept.php on line 6

Fatal error: Call to a member function assign() on a non-object in C:\AppServ\www\somefo\accept.php on line 11

I don't know why it shows this .. and I hope you answer me and what or how to solve this problem

Thanks ..

For php:

<?php

$sql = mysql_connect(......);  // connect to your server
if (!$sql) {
    die('Can\'t connect to database');
}

// select your database
mysql_select_db('your_db', $sql) or die('Can\'t select database');

$time = date("i:s",time("s"));
$sql_select_invite_query = "SELECT * FROM invite WHERE recid = '$_SESSION[id]' AND accept = '0' AND endtime > '$time'";

// print it if you want to see sql query to test it in phpmyadmin
echo $sql_select_invite_query; 
// --------------------------------------------------------------

$sql_select_invite = mysql_query($sql_select_invite_query, $sql);

if (!$sql_select_invite) {    // check for error in query
    die(mysql_error());       // and print it
}

$invites = array();  // don't forget to make an empty array

while($invite = mysql_fetch_array($sql_select_invite, $sql)){
    // this place is not good, just make it as you do before, with checks
    $sender = mysql_fetch_array(mysql_query("SELECT * FROM member WHERE id = '$invite[sendid]'"));

    $contest->assign("sender", $sender);
    $invites[] = $invite;
}
$contest->assign("invites", $invites);   // in your case there is no $invite 
                                         // array cause mysql_fetch_array returned
                                         // false and it is not defined before [while]

?>

For JS to test:

setInterval( function () {
  $('#invite').load('accept.php', function() {
    alert('loaded');  // it is to check content is loaded
  }).fadeIn("slow");
}, 1000);
