Question

I have the following PHP script, But it seems to be always checking for the session and therefore echos out “please enter the correct code before the user has even entered a code.

I would like to at a click event before the code actually fires and does the check for the session and post of the form. How can this be done in PHP?

here is my code:

<?php

session_start();
    if (md5($_POST['norobot']) == $_SESSION['randomnr2'])   
    { 
        // here you  place code to be executed if the captcha test passes
            echo "Code correct - email should send now";

}   

else {  
        // here you  place code to be executed if the captcha test fails
            echo "Code incorect please try again";
    }

?> 

my submit buttons looks like this:

<input type="submit" id="submit_btn" class="button" value="Submit" />

<?php
    session_start();
    if (isset($_POST['norobot'])) {
        if (md5($_POST['norobot']) == $_SESSION['randomnr2']) {
            // here you  place code to be executed if the captcha test passes
            echo "Code correct - email should send now";
        }
        else {
            // here you  place code to be executed if the captcha test fails
            echo "Code incorect please try again";
        }
    }
?>
