仅在重定向但不使用php键入url时显示页面

Question

I am trying to show a page only when its redirected through submit button.For example.
If the main url is http://www.example.com

 Am having form in `http://wwww.example.com/form.php` and when its submitted its         
 redirected to http://wwww.example.com/success.php

but if the user types http://wwww.example.com/success.php in the browser URL how can I redirect it to form.php if the form is not submitted.

Answer 1

Please create a SESSION variable on form.php just before redirecting to success.php & check that SESSION variable on success.php. Just like this:

On form.php

<?php
session_start();
$SESSION['user'] = '$user_name';    //Put your username in this or any value which you want to check on success.php page
header("Location : http://wwww.example.com/success.php");
?>

And now on success.php

<?php session_start();
if(!isset($SESSION['user'])){
   header("Location : http://wwww.example.com/form.php");
}

//Now your success.php code & content
?>

Hope, this may be helpful for you.
