Problem: users click submit over and over

[jasondavis]

My problem is that users submit a form on my site which post to mysql, sometimes they will click 5-6 times in a row really fast and it will post it that many time, how can I avoid this?

I tried

<input type="submit" name="postbulletin" value="Post Bulletin" onclick="this.disabled=true;document.form1.submit()" class="button">

It disables the button and submits it but not correctly

Hi Jason,

I do something like this.

On the form page I set a session variable like.

session_start(); // this must be on your pages and before any HTML
if($_SESSION['AUTHORIZED'] != "YES") {
$_SESSION['AUTHORIZED']="YES";
//All your form code goes here.
} else {
die("Sorry, whatever you want to tell them goes here.");
}

What this does is check to see if they submitted the form, and if no, then let them proceed. Otherwise, the "die("....." at the end.

There are other ways of doing this, this just seems to work well for me.

I see what you mean the problem is when teh submit button is shown, they can hit it multiple times really fast and it will post multiple times, I have tried all the javascript methods and all of them make my php script return an error instead of posting
