so should I put that with this code or in the processing piece of the code?  and if it is with this, can you help get me started?

if (isset($_POST['eventid'])){
$name = ereg_replace("[^A-Z a-z0-9]", "", $_POST['name']); // filter everything but numbers and letters
$event = ereg_replace("[^A-Z a-z0-9]", "", $_POST['event']); // filter everything but spaces, numbers, and letters
$eventid = ereg_replace("[^A-Z a-z0-9]", "", $_POST['eventid']); // filter everything but spaces, numbers, and letters
$userid = ereg_replace("[^A-Z a-z0-9]", "", $_POST['userid']);  
$title1 = ereg_replace("[^A-Z a-z0-9]", "", $_POST['title1']); // filter everything but spaces, numbers, and letters
$title2 = ereg_replace("[^A-Za-z0-9]", "", $_POST['title2']); // filter everything but lowercase letters
$title3 = ereg_replace("[^A-Za-z0-9]", "", $_POST['title3']); // filter everything but lowercase letters
$title4 = ereg_replace("[^A-Za-z0-9]", "", $_POST['title4']); // filter everything but lowercase letters
$title5 = ereg_replace("[^A-Za-z0-9]", "", $_POST['title5']); // filter everything but lowercase letters
$title6 = ereg_replace("[^A-Z a-z0-9]", "", $_POST['title6']); // filter everything but 
$title7 = ereg_replace("[^A-Z a-z0-9]", "", $_POST['title7']); // filter everything but 
$title8 = ereg_replace("[^A-Z a-z0-9]", "", $_POST['title8']); // filter everything but 

$email = ereg_replace("[^A-Z a-z0-9.@]", "", $_POST['email']); // filter everything but 
$price1 = ereg_replace("[^A-Z a-z0-9.@]", "", $_POST['price1']); // filter everything but 
$price2 = ereg_replace("[^A-Z a-z0-9.@]", "", $_POST['price2']); // filter everything but 
$price3 = ereg_replace("[^A-Z a-z0-9.@]", "", $_POST['price3']); // filter everything but 
$price4 = ereg_replace("[^A-Z a-z0-9.@]", "", $_POST['price4']); // filter everything but 
$price5 = ereg_replace("[^A-Z a-z0-9.@]", "", $_POST['price5']); // filter everything but 
$price6 = ereg_replace("[^A-Z a-z0-9.@]", "", $_POST['price6']); // filter everything but 
$price7 = ereg_replace("[^A-Z a-z0-9.@]", "", $_POST['price7']); // filter everything but 
$price8 = ereg_replace("[^A-Z a-z0-9.@]", "", $_POST['price8']); // filter everything but 
$id = ereg_replace("[^A-Z a-z0-9.@,]", "", $_POST['id']); // filter everything but 

$sql = "REPLACE INTO Events (name, event, eventid, userid, title1, title2, title3, title4, title5, title6, title7, title8, email, id, price1, price2, price3, price4, price5, price6, price7, price8) 
	VALUES('$name','$event','$eventid','$userid','$title1','$title2','$title3','$title4','$title5','$title6','$title7','$title8','$email','$id','$price1', '$price2', '$price3','$price4','$price5','$price6','$price7','$price8')";
$rs = mysql_query($sql) or die ("Problem with the query: $sql<br>" . mysql_error());

That would be used in the processing code that deals with the associated form, it seems like the code you posted deals with the form submission so yes it would go in that code.

 

<?php
if (isset($_POST['eventid'])){
if (isset($_POST['title8'])) {
  $price8 = ereg_replace("[^A-Z a-z0-9.@]", "", $_POST['price8']); // filter everything but 
} else {
  $price8 = ""; // What value do you want it to hold if the box is unchecked? As it stands it holds nothing.
}
// All your other post data here except $price8
}
?>

 

You could place this after your first if statement, drop the $price8 variable from your orig code.
