When a user submits a form and clicks on the back button how can he view his already entered data??

I really need to knw this.

Hey guys, i got the solution......... its pretty annoying but simple.

Just use cookie.

<?php
setcookie("user", "Alex Porter", time()+3600);
?>

and

<?php// Print a cookieecho $_COOKIE["user"];// A way to view all cookies
print_r($_COOKIE);
?>

does the trick............ your user wont be annoyed when he fills forms on your website

Cookies can be an annoyance by themselves, especially if your User turns them off or disables JavaScript.

Are you trying to save the data when the User submits the form, or when he navigates away from your page?

If you just want to save the data when the User submits the form, all you have to do is store the User's input in the session --

[php]
foreach($_REQUEST as $key => $val)
if($key != 'PHPSESSID')
$_SESSION['form1data_or_whatever'][$key] = Validator::makeSafe($val);
[/php]

This assumes, of course, that you wrote a validator class to safe your input. If you didn't, you could use validator.class.php .

Anyway, then on your HTML form:

<input name="email" type="text" value="<?php echo $_SESSION['form1data_or_whatever']['email']; ?>/>
 

Bonus points if you set up a Smarty tag instead!

Generally speaking, the form data should not be lost if you press the back button unless you prevent caching and force a reload of each page.
