Regarding Payment "dupicate data into database"

[seeya]

got a question..

 

when customers click buy products from our website and click the "Back button" in IE, users can actually send dupicate into database when they press send again.

 

Any way i can make the "Back Button" turns into a Timeout page or something?

 

Thanks alot

you sure it isn't that the customers press the 'submit' button a second time because the wait is so long? You want to use javascript to lockout the submit button on the form after submitting:

<script>
var dosubmit = true;
</script>
<form name="test"  action="url" onsubmit="if (dosubmit) { dosubmit=false;return true;} else { return false; }">

--the javascript in the 'onsubmit' will 'return true' the first time through but 'return false' the second time through ,stopping the form submit
