---|
| 213 | * Routes are a way of connecting request urls to objects in your application. At their core routes |
---|
| 214 | * are a set or regular expressions that are used to match requests to destinations. |
---|
| 215 | * |
---|
| 216 | * Examples: |
---|
| 217 | * |
---|
| 218 | * `Router::connect('/:controller/:action/*');` |
---|
| 219 | * |
---|
| 220 | * The first parameter will be used as a controller name while the second is used as the action name. |
---|
| 221 | * the '/*' syntax makes this route greedy in that it will match requests like `/posts/index` as well as requests |
---|
| 222 | * like `/posts/edit/1/foo/bar`. |
---|
| 223 | * |
---|
| 224 | * `Router::connect('/home-page', array('controller' => 'pages', 'action' => 'display', 'home'));` |
---|
| 225 | * |
---|
| 226 | * The above shows the use of route parameter defaults. And providing routing parameters for a static route. |
---|
| 227 | * |
---|
| 228 | * {{{ |
---|
| 229 | * Router::connect( |
---|
| 230 | * '/:lang/:controller/:action/:id', |
---|
| 231 | * array(), |
---|
| 232 | * array('id' => '[0-9]+', 'lang' => '[a-z]{3}') |

---|

---|
| 236 | * Shows connecting a route with custom route parameters as well as providing patterns for those parameters. |
---|
| 237 | * Patterns for routing parameters do not need capturing groups, as one will be added for each route params. |
---|
| 238 | * |
---|
| 239 | * $options offers three 'special' keys. `pass`, `persist` and `routeClass` have special meaning in the $options array. |
---|
| 240 | * |
---|
| 241 | * `pass` is used to define which of the routed parameters should be shifted into the pass array. Adding a |
---|
| 242 | * parameter to pass will remove it from the regular route array. Ex. `'pass' => array('slug')` |
---|
| 243 | * |
---|
| 244 | * `persist` is used to define which route parameters should be automatically included when generating |
---|
| 245 | * new urls. You can override persistent parameters by redefining them in a url or remove them by |
---|
| 246 | * setting the parameter to `false`. Ex. `'persist' => array('lang')` |
---|
| 247 | * |
---|
| 248 | * `routeClass` is used to extend and change how individual routes parse requests and handle reverse routing, |
---|
| 249 | * via a custom routing class. Ex. `'routeClass' => 'SlugRoute'` |
---|
| 250 | * |
---|
| 251 | * @param string $route A string describing the template of the route |
---|
| 252 | * @param array $defaults An array describing the default route parameters. These parameters will be used by default |
---|
| 253 | * and can supply routing parameters that are not dynamic. See above. |
---|
| 254 | * @param array $options An array matching the named elements in the route to regular expressions which that |
---|
| 255 | * element should match. Also contains additional parameters such as which routed parameters should be |
---|
| 256 | * shifted into the passed arguments, supplying patterns for routing parameters and supplying the name of a |
