Question

I’d like to create a simple password form or script that redirects the visitor to another page after the correct password has been entered.

The only security requirement is some sort of password scrambling / hashing (if the password is visible in source code).

The password ain’t protecting anything valuable but it would be used in a web-based competition, and that’s why it’s important to minimize the obvious cheating options 🙂

I cannot code much myself (beyond HTML/CSS) so any help is greatly appreciated. I think this kind of script would be useful for other coding newbies also.

If you have any further questions, fire away!

Answer 1

HTML form with method post and href to ‘auth.php’;

<form action="/auth.php" method="POST"><input type="text" name="password"><input type="submit" value="Submit"></form>

source of auth.php:

<?php
if(!empty($_POST['password'])) { 
    if(md5('blah@#$'.sha1('3NhNj8&'.$_POST['password']) ) =='MD5 value of your password' ) {
    header("Location: http://www.nextpage.com"); /* Redirect here if the password is correct */
    }
    else {
        header("Location: http://www.pagewheretheformis.com"); /* Return here if the password ain't correct */
    }   
}
else {
    header("Location: http://www.pagewheretheformis.com"); /* Return here if the field is empty */
}
?>

So you just need to run one time:

<?php echo md5('blah@#$'.sha1('3NhNj8&'."yourpassword")); ?>

and insert it into code above 🙂
