prevent user from going back or disable submit
 

i have a form being filled. i don't want the user to be able to submit twice. how can i either prevent the user from going back or disable the submit button?

i am currently disabling the submit button but when the user clicks back(from the next page) it asks whether it should resend data. when the data is resent it loads the original version of the page(without submit disabled).

can someone help me with this? thanks.

i tried using sessions..
i set a sessions variable to 1 if the form data was submitted.
i check if the the variable is one on the concerned page and if it is i call a function which disables the submit button. but this doesnt work either. any thoughts about this?

heres the code

<?php

if($_SESSION['disable']==1){

echo "<script type="text/javascript"> disablesbmt(); </script>";

}

?>
