I've got a link, and wen i click on it, a new php file which contains a form appears...
This form i fill it up and click the submit button, and wen i do it, all ma details are stored in the database.
Next time wen i try to fill the same form and wen i try to send it by clicking the submit button.... nothing shud happen...
i.e. Only once that form cud be filled and sent....
I have two php files.... One is form.php, in which i have the coding for form design and the other if formappln.php, which is the application file.
Can u help me out....

you need to use some IP or Cookie protection first to prevent people submitting the form twice. When they first submit the form you can put a cookie and next time they open the page you can check if cooke exists and if it's there do not show the form at all.

The function is setcookie()
An example would be:
setcookie("form", "some value", time()+2678400);
This will set the cookie that expires in one month. That line must be like session_start(), before outputing any text.
To check for the cookie, you can use if(isset($_COOKIE['form'])).
You can read more information about that function on http://www.php.net/setcookie
