  • Passing Email Addresses in URLs With CodeIgniter

    #PHP #configuration #security #CodeIgniter

    CodeIgniter has some handy security features that sometimes get in the way. One such feature is URI scrubbing for disallowed characters. There are probably more secure ways to tell a script what email address to use than to pass it directly via URI. I'm using this for a simple intranet application to manage email recipients for a UPS & FedEx tracking emailer. So it is not important to cloak the email address being passed. Make sure this method is right for your project before you use it. It can expose email addresses to being indexed by spam bots or intercepted by hackers. Note: Ian Huet has provided a great solution using jQuery's AJAX functionality to pass the email in a POST request which bypasses the issue covered in this article entirely. Find it in the comments.

So, 'a' becomes 'z', 'b' becomes 'a', 'c' becomes 'b', and so on. First, we'll need a script to encrypt the message. We'll also need a script to decrypt the message just for good measure. So I give you, shift.php and unshift.php.

All we have to do is set up the ak_twitter table in the database. Keep reading for the how-to.
