Customized 404 page in PHP Phalcon framework

Phanix

在一般狀況下其實不需要自訂404 page也不會怎麼樣,但是如果用 phalcon dev tools 做 CRUD 頁面出來,有些狀況可能是不需要 create 資料的,比方說對 log 只需要看,沒有道理從頁面上手動 create

在 app/controllers/ 下開一個 ErrorController.php

<?php /**
 * ErrorController 
 */
class ErrorController extends \Phalcon\Mvc\Controller
{
    public function show404Action()
    {
        $this->response->setStatusCode(404, 'Not Found');
        error_log("test");
        $this->view->pick('404/404');
    }
}

在 app/config/services.php 新增

$di->set(
    'dispatcher',
    function() use ($di) {

        $evManager = $di->getShared('eventsManager');

        $evManager->attach(
            "dispatch:beforeException",
            function($event, $dispatcher, $exception)
            {
                switch ($exception->getCode()) {
                    case Dispatcher::EXCEPTION_HANDLER_NOT_FOUND:
                    case Dispatcher::EXCEPTION_ACTION_NOT_FOUND:
                        error_log("testssss");
                        $dispatcher->forward(
                            array(
                                'controller' => 'Error',
                                'action'     => 'show404',
                            )
                        );
                        return false;
                }
            }
        );
        $dispatcher = new Dispatcher();
        $dispatcher->setEventsManager($evManager);
        return $dispatcher;
    },
    true
);

然後在 app/views/ 新增 404/404.volt

然後在要關掉功能的 action,例如 LogController 內關掉 newAction()

<?php use Phalcon\Mvc\Model\Criteria;
use Phalcon\Paginator\Adapter\Model as Paginator;


class LogController extends ControllerBase
{
/* skip some code */
    public function newAction()
    {
        $e = new Exception("", Phalcon\Mvc\Dispatcher::EXCEPTION_ACTION_NOT_FOUND);
        throw $e;
    }
/* skip some code */
}
