i just set up a validation on this form but when there is an error and the user hits back to fix it, all the fields are reset. Is there a code to fix this?

I'd simply redisplay the form on error with any valid data in place from the last submission. no need to click the back button then

I'll elaborate on mikesmith76's post. Wherever you post your form (the same page or another) you should have a copy of that form to redisplay incase of errors. Using isset() makes it simple to redisplay the information in the error form. For example:

if (isset($_POST['submit']) && $_POST['submit'] == 'submit'){//-> submitted - process data

$err = array();//initialize error array

if (isset($_POST['name']) && preg....){
$name = $_POST['name'];
} else {
$err['name'] = 'You forgot to enter your name';
}

if (empty($err)){//-> No errors

/////////--->> Process Here

} else {//Errors - show error form

if (!empty($err['name'])) echo $err['name'];
?>

Enter Your Name<br>
<input name="name" type="text" value="<?php if (isset($_POST['name'])) echo $_POST['name'];?>" size="30" maxlength="30">

<?
}

} else {//-> not submitted - show form

?>
<html>
<body>
<form method.......

Enter Your Name<br>
<input name="name" type="text" size="30" maxlength="30">

</form>

<?
}
?>
