What I am trying to do with this script is allow users to update a url for their websites, and since each user isn't going to have the same amount of websites is is hard for me to just add $_POST['website'] for each of these.

Here is the script

<?php
include("config.php");
include("header.php");
include("functions.php");

if(!isset($_SESSION['username']) && !isset($_SESSION['password'])){
    header("Location: pubs.php");
    }

$getmember = mysql_query("SELECT * FROM `publishers` WHERE username = '".$_SESSION['username']."'");
$info = mysql_fetch_array($getmember);
$getsites = mysql_query("SELECT * FROM `websites` WHERE publisher = '".$info['username']."'");

$postback = $_POST['website'];
$webname = $_POST['webid'];
if($_POST['submit']){
var_dump( $_POST['website'] );
$update = mysql_query("UPDATE `websites` SET `postback` = '$postback' WHERE name = '$webname'");
}


print"
<div id='center'>
<span id='tools_lander'><a href='export.php'>Export Campaigns</a></span>
<div id='calendar_holder'>
<h3>Please define a postback for each of your websites below. The following variables should be used when creating your postback.<br />
cid = Campaign ID<br />
sid = Sub ID<br />
rate = Campaign Rate<br />
status = Status of Lead. 1 means payable 2 mean reversed<br />
A sample postback URL would be <br />
http://www.example.com/postback.php?cid=#cid&sid=#sid&rate=#rate&status=#status</h3>
<table class='balances' align='center'>
<form method='POST' action=''>";

while($website = mysql_fetch_array($getsites)){
print"
<tr>
<input type ='hidden' name='webid' value='".$website['id']."' />
<td style='font-weight:bold;'>".$website['name']."'s Postback:</td>
<td><input type='text' style='width:400px;' name='website[]' value='".$website['postback']."' /></td>
</tr>";
}
print"
<td style='float:right;position:relative;left:150px;'><input type='submit' name='submit' style='font-size:15px;height:30px;width:100px;' value='Submit' /></td>
</form>
</table>
</div>";

include("footer.php");
?>

What I am attempting to do insert the what is inputted in the text boxes to their corresponding websites, and I cannot think of any other way to do it, and this obviously does not works and returns a notice stating Array to string conversion If there is a more logical way to do this please let me know.
