PHP Saving Session Variable

Question

I am trying a new CAPTCHA Script from here. To call the CAPTCHA code you use: $_SESSION['captcha']['code']

Well that works when I echo it out on the main form, but when I echo it after the form has been submitted, it displays a new code so I can never find out what the old code was when they submitted the form.

if($_POST['submit']) {
    echo $_SESSION['captcha']['code'];
}

How can I save that session data and not make it change any more?

You need verify if your captcha code is rewrite the session variable when the page reload. Probably you'll need make changes on this code. — GodFather

You should store it in your own SESSION variable:

$_SESSION['old_captcha'] = $_SESSION['captcha'];

Then, when the form is submitted, use you own variable:

if($_POST['submit']) {
    echo $_SESSION['old_captcha']['code'];
}

Put that BEFORE you include the captcha.php again on the next step.

My guess is that it displays a new code because you come back to the page that displays it. Try submitting to a different page, or maybe not executing the captcha creation code if the session variable is already set.
