I don't think you can stop a user going back if he wishes by simply clicking on the browser back button.
What you can do instead is to set session variables as he visits each stage. If he resubmits a page that has it's session variable already set then you can indicate your preferred error message (using php).
example
php Syntax (Toggle Plain Text) 
  1. <?php
  2. if($_SESSION['user_details_form_submitted']==1){
  3. echo "You are not allowed to resubmit!!";
  4. exit();
  5. }
  6. ?>
Put this at the top of the script doing the validation.
Hope it helps!!!

Yes you!! can put PHP into javascript but PHP will be executed first and thus it will only print whatever you have specified into the javascript code. Like in this example:

php Syntax (Toggle Plain Text) 
  1. <?php
  2. $myname="ronaldinho gaucho";
  3.  ?>
javascript Syntax (Toggle Plain Text) 
  1. <script type="text/javascript">
  2. function showMyName()
  3. {
  4. alert("My name is "+<?php echo "\"".$myname."\""; ?>);
  5. }
  6. </script>
html Syntax (Toggle Plain Text) 
  1. <body onload="showMyName()">
  2. </body>
Note that this must be placed inline. It cannot be placed in an external javscript file!!
