How do you stop multiple submit hits

Anon

Just wondering if anyone knew how to stop idiots from hitting the submit button a zillion times and posting a zillion comments.

Thanks =p

You can't do anything about with PHP, because by the time someone is clicking a button the PHP is done parsting but I used to use a javascript function to accomplish that.

Basically add an onClick event to the submit button that makes "form.submitbuttonname.enabled = false".

There is a convoluted function, on Dynamicdrive.com I think, that does the same thing but onSubmit event instead.

Why dont you just use sessions to set a FLAG which is activated once a user has submitted.

That way you can do somthing like this

if ($SubmitFlag==TRUE){
//dont let them post and
//tell them they're very naughty
} else {
//let them post
}

Hope that helps

If you take the users IP address when they submit then you can use this to check against. It is a common feature large e-companies use. It works well because you are not sending data to the client side (it is all held sever side in a text file or database).

The one down fall of it is that people behind a fire wall routing through an IP boost would all appear to have the same IP address. [n.b this is not always true though]

But in my experience this is a pretty effective way of stopping multiple submissions.
