Hello Reader's!, If you need a nice method to stop the form from again and again submit via refresh, PHP offers you many ways like header redriect or unset the $_POST but a pretty way is to implement a unique ID into the post and cache it in the

Lets see the examle below:-

<input type='hidden' name='post_id' value='".createPassword(64)."'>
Then in your code do this:

if( ($_SESSION['post_id'] != $_POST['post_id']) )
{
    $&_SESSION['post_d'] = $_POST['post_;id'];
    //do post stuff
} else {
    //normal display
}

function createPassword($length)
{
    $chars = "abcdefghijkmnopqrstuvwxyz023456789";
    srand((double)microtime()*1000000);
    $i = 0;
    $pass = '' ;

    while ($i <= ($length - 1)) {
        $num = rand() % 33;
        $tmp = substr($chars, $num, 1);
        $pass = $pass . $tmp;
        $i++;
    }
    return $pass;
}

Now every time a unique ID will be genrated and if it match then only you proceed
