Question

I am new to PHP so as I am learning I just discovered that you can go directly to a page like domain.com/process.php and the page would still run.

How can I prevent a user from directly accessing the page and make sure they got to the process.php after they have submitted the form?

Answer 1

Simply, use this code :

<?php
if(!isset($_POST['submit']))
{
echo 'Try accessing this page by pressing submit button'. '<br />';
echo "<a href='form.html'>Goto Form Page</a>";
exit();
}
?>

// here 'submit' is the name attribute within your input tag for submit button
/*
It simply means if submit button is not pressed, echo the following message and 
exit don't run anything else. You can also use die('Your message here') 
instead of exit();
*/
