Question what this has to do with Java Server Pages? Your page is linked to PHP. Are you sure you didn't wanted to post in JavaScript?

Hi,
here's a short bit of example on how you would be able to clear those field values:

<html>
<head>
<title>Live Help</title>
<script type="text/javascript">
<!--
var clearFields = function() {

var form = document.getElementById("registerForm") || document.forms.registerForm;
var elem = { 
	0 : "First_name",
	1 : "Last_name",
	2 : "Username",
	3 : "Password",
	4 : "re_Password",
	5 : "Email",
	6 : "contactno",
	7 : "country" };
	
	
	
	if ( "elements" in form ) {

		for ( var i in elem ) {
			form.elements[ String( elem[ i ] ) ].value = "";
		} return false;


	} for ( var i in elem ) {
		form.getElementsByTagName("input")[ String( elem[ i ] ) ].value = "";

	} return false;

};

-->
</script>

</head>

            </tr>
          </table>
        </form>
</body>
</html>

just be sure to find the right spot inside your AJAX handler in which you want to execute the code sample...

Edited by ryan311: i forgot

after submitting your data at the backend your fileds automatically will be blank.......

0

after the success add you have to use unlink($variablename) and you clear each variable

Wow! That was a lot complicated answers! I think it should be just as easy as:

document.getElementById("id").value = "";
//element.value = "";

Ya know, I think what he's wanting just hit me.

Correct me if I am wrong. You want the user to fill in the appropriate fields. Then, on submit, the fields are validated. If they do NOT validate, you want the fields to still contain the users information. Also, if something happens during registration, and the sql was refused, etc, then you want the fields to still be populated. ONLY IF the submission is successful, THEN you want the information cleared and blanked.

Am I close?

My 2¢. Hope this clarifies things. (and has a sneaky suspicion that, if we go into carrying variables via sessions, that this thread will end up BACK in the PHP section again...) LOL :)
