Stopping users posting more than once
- by user342391
Before posting my form I am checking the database to see if there are any previous posts from the user. If there are previous posts then the script will kick back a message saying you have already posted.
The problem is that what I am trying to achieve isn't working it all goes wrong after my else statement. It is also probable that there is an sql injection vulnerability too. Can you help??4
<?php
include '../login/dbc.php';
page_protect();
$customerid = $_SESSION['user_id'];
$checkid = "SELECT customerid FROM content WHERE customerid = $customerid";
if ($checkid = $customerid) {echo 'You cannot post any more entries, you have already created one';}
else
$sql="INSERT INTO content (customerid, weburl, title, description) VALUES
('$_POST[customerid]','$_POST[webaddress]','$_POST[pagetitle]','$_POST[pagedescription]')";
if (!mysql_query($sql))
{
die('Error: ' . mysql_error());
}
echo "1 record added";
?>
