Route Component for CakePHP 1.2.*

January 24th, 2009 | Tags: ,

I wrote this component for a simple content management system that I was building for a customer that I will go over in another upcoming post. It can be used to create and remove routes on the fly.

/app/controllers/components/route.php

<?php
class RouteComponent extends Object {
    var $route_file = '../config/routes.php';
   
    function initialize() {
        if (!is_file($this->route_file)) {
            die('The path to your route file is wrong. Edit /app/controllers/components/route.php and fix the problem.');
        }
    }
   
    function add($route) {
        $route = $route."\n";
        if (is_writable($this->route_file)) {
            $routes = file($this->route_file);
            $new_routes = '';
            foreach ($routes as $i) {

Usage

If you paste this into a new document be sure and check for spaces before and after your php tags. That is something I catch a lot and if you don’t know to look for them it can be a pain to debug. After you have uploaded the route file you will need to enable it inside your controller.

var $components = array('Route');

Then it can be used by passing the full route to either the add or remove methods. I might rewrite this later to accept $origin and $destination instead of passing the full route. For now it just seemed like a lot of unnecessary work. Let me know what you think.

# To create a route
$this->Route->add("Router::connect('/foo', array('controller' => 'pages', 'action' => 'display', 'foo'));");
# To remove a route
$this->Route->remove("Router::connect('/foo', array('controller' => 'pages', 'action' => 'display', 'foo'));");
