The Bakery Everything CakePHP

Overview

Use this model to create tickets or tokens so you can match a url link in an email to reset a users password, activate an account, moderate content or anything else you can think of.

I saw there were a few alternatives but using components. This is a cleaned up and more basic version. Thanks to mndeaves for a starting block :)

You're welcome to alter the code to your needs. You may want to destroy a ticket after it's been checked.

Installation

• Create the table
• Save this script below into your models directory
• Add to your $uses controller variable, public $uses = array('Ticket')

Usage

• $this->Ticket->generate([$data]); // Create ticket, returns created ticket record
• $this->Ticket->check([$hash]); // Check a hash exists, returns boolean
• $this->Ticket->void([$hash]); // Delete ticket
