What I do is store all the fields in $_SESSION variables, so when you go back to the page, if they filled that particular field out, it should show what they have already completed.
------------------ <?php session_start();
if ($_POST["submitted"] == 1) {
$_SESSION["field1"] = $_POST["something"];
$_SESSION["field2"] = $_POST["pizza"];
}
?><form action="wherever.php" method="post">
<input type="text" name="something" value="<? echo $_SESSION["field1"]; ?>"/>
<input type="text" name="pizza" value="<? echo $_SESSION["field2"]; ?>"/>
<input type="submit" value="GO"/>
<input type="hidden" name="submitted" value="1"/>
</form>
------------------
So, there's no need to use javascript or to actually "go back." You can just "redirect" to that page and have it "remember" the variables. To redirect back to it, use header("location: http://mysite.com/wherever.php";); It is not *always* necessary to use the absolute path to indicate that particular page in the header() function, but it doesn't hurt.
Sorry if I have rambled on or confused you - it's late and I'm sleepy. Good luck with that.
