I have one page website, on homepage(Layout/default.ctp) I have 2 forms, subscribe and contact form that are being controlled over contact controller. With $this->set('some_val', 'test'); I can set value from AppController, but not from contact controller, how can I set values from contact controller to be available in default.ctp except with sessions?
public function beforeFilter() {
parent::beforeFilter();
//pr('beforeFilter'); // i was testing is this happening or not
//exit();
$tester = 'test';
$this->set(compact('tester'));
}
and in default.ctp I just pr($this->viewVars); to make sure that I have tester value, but it is always empty.
Is this right approach how to implement several controllers in one page design?
Another question is there a place/function where I could check is current request post or not, I would like to check for each request what is it?
Thank you.
Not sure if I understand correctly, but it sounds like you might need multiple layouts:
class CarsController extends AppController
{
public function index($page)
{
/* Your logic */
if ( $page == 'other' ) {
$this->render('view', 'layout');
} else {
$this->render('view-other', 'layout-other');
}
}
}
For more information i'd suggest looking at: http://api20.cakephp.org/class/controller#method-Controllerrender
try an echo $tester; in your default, it should be available.
If the request is post, you would have data in $this->data.

I have written a plugin for CakePHP 3.4.*.
This plugin will check for Database configuration has been set or not, if not then It you move user through a GUI interface to setup database configuration just like wordpress.
The plugin is working perfectly, but it has to be loaded manually by visiting url of the plugin
http://example.com/installer/install
where installer is the plugin name which is calling InstallController class inside plugins/Installer/src/Controller/ directory
Now what I want to check it automatically and redirect user to the Installation interface if database connection couldn't be established.
For that I have written a function inside InstallController of plugin's controller
public function installationCheck() {
$db = ConnectionManager::get('default');
if(!$db->connect()) {
if(Configure::read('Database.installed') == true) {
$this->Flash->error(__("Database connection couldn't be established. Please, re-configure it to start the application"));
return $this->redirect(['action' => 'index']);
} else {
$this->Flash->error(__("Please configure your database settings for working of your application"));
return $this->redirect(['action' => 'index']);
}
}
return true;
}
Now the Question.
What is the easiest way to call this method from /app/src/Controller/AppController.php file of the main application?
Simple answer, you don't!
Shared controller logic belongs either in AppController itself, a Component or a Trait. The AppController should never being accessing methods defined in other controllers, these shouldn't be made accessible to it.
For what you're doing you probably want to do this in a component that you can load via your AppController or the relevant controller.
So your component would look something like:-
<?php
namespace Installer\Controller\Component;
use Cake\Controller\Component;
class InstallComponent extends Component
{
public function installationCheck()
{
// Method's logic
}
}
Which you would then load in the relevant controller:-
public function initialize()
{
parent::initialize();
$this->loadComponent('Installer.Install');
}
Then you can use the component's method from the controller like:-
$this->Install->installationCheck();
You should not Do that!
If you need to access another controller I recommend you to move that functionality to a Component, that are packages of logic that are shared between controllers.
Currently, I'm using the CRUD v4 plugin for Cakephp 3. For the edit function in my user controller it is important that only a user itself can alter his or her credentials. I want to make this possible by inserting the user id from the authentication component. The following controller method:
public function edit($id = null){
$this->Crud->on('beforeSave', function(\Cake\Event\Event $event) {
$event->subject()->entity->id = $this->Auth->user('id');
});
return $this->Crud->execute();
}
How can I make sure I don't need to give the id through the url? The standard implementation requires the url give like this: http://domain.com/api/users/edit/1.json through PUT request. What I want to do is that a user can just fill in http://domain.com/api/users/edit.json and send a JSON body with it.
I already tried several things under which:
$id = null when the parameter is given, like in the example above. Without giving any id in the url this will throw a 404 error which is caused by the _notFound method in the FindMethodTrait.php
Use beforeFind instead of beforeSave. This doesn't work either since this isn't the appropriate method for the edit function.
Give just a random id which doesn't exist in the database. This will through a 404 error. I think this is the most significant sign (combined with point 1) that there is something wrong. Since I try to overwrite this value, the CRUD plugin doesn't allow me to do that in a way that my inserting value is just totally ignored (overwriting the $event->subject()->entity->id).
Try to access the method with PUT through http://domain.com/api/users.json. This will try to route the action to the index method.
Just a few checks: the controllerTrait is used in my AppController and the crud edit function is not disabled.
Does anyone know what I'm doing wrong here? Is this a bug?
I personally would use the controller authorize in the Auth component to prevent anyone from updating someone else's information. That way you do not have to change up the crud code. Something like this...
Add this line to config of the Auth component (which is probably in your AppController):
'authorize' => ['Controller']
Then, inside the app controller create a function called isAuthorized:
public function isAuthorized($user) {
return true;
}
Then, inside your UsersController you can override the isAuthorized function:
public function isAuthorized($user) {
// The owner of an article can edit and delete it
if (in_array($this->request->action, ['edit'])) {
$userId = (int)$this->request->params['pass'][0];
if ($user['id'] !== $userId) {
return false;
}
}
return parent::isAuthorized($user);
}
When I click the Enroll Now button under admissions on my navigation bar, \merry_flowers\views\students\add.ctp should display.
Instead, the login page is getting displayed.
Does anyone know on what I'm doing wrong?
The following is my app_controller.php for the project:
class AppController extends Controller {
var $components=array('Auth','Session','Cookie');
function beforeFilter(){
if (isset($this->Auth)){
$this->Auth->userModel='MerryParent';
$this->Auth->loginAction=array('controller'=>'merry_parents','action'=>'login');
//var_dump($this->data);
$this->Auth->allow('*');
$this->Auth->loginRedirect=array('controller'=>'merry_parents','action'=>'report_card');
$this->Auth->logoutRedirect=array('controller'=>'merry_parents','action'=>'register');
$this->Auth->deny('report_card');
$this->Auth->authorize='controller';
}
else
$this->Session->setFlash('Auth has not been set');
}
function isAuthorized(){
return true;
}
Any help is much appreciated.
One gotcha is if your StudentsController has a beforeFilter, you'll need to call parent::beforeFilter or that Auth setup won't happen.
I'd also note the caveat for using authorize = 'controller'; "Remember that [isAuthorized] will be checked after you have already passed the basic authentication check against the user model.". Given that you have $this->Auth->allow('*'), auth should be skipped entirely, so I'd look for a more fundamental mistake such as the beforeFilter override.
Unfortunately nothing stands out in your pasted code. Auth problems usually involve facepalm solutions in my experience :)
i am new with cake but i´ve somehow managed to get through so far. After i´ve figured out that html2pdf is a convienient way to produce pdf documents out of Cakephp, i´ve installed html2ps/pdf and after some minor problems it worked. So now i am coming now to the point that if i don´t modify my controllers beforeRender function like:
function beforeFilter() {
parent::beforeFilter();
$this->Auth->allow('download','view');
}
i just see my loginpage in the pdf i´ve created. Setting within my beforeRender function the $this->Auth->allow value opens obviously erveryone the way to get a perfect pdf without being authorized. The whole controller looks like this:
<?php
class DashboardController extends AppController {
var $name = 'Dashboard';
var $uses = array('Aircrafts','Trainingplans',
'Fstds','Flights','Properties','Person');
function beforeFilter() {
parent::beforeFilter();
$this->Auth->allow('download','view');
}
function view() {
/* set layout for print */
$this->layout = 'pdf';
/* change layout for browser */
if> (!isset($this->params['named']['print']))
$this->layout = 'dashboard';
/* aircrafts */
$this->Aircrafts->recursive = 0;
$aircrafts =$this->Aircrafts->find('all');
$this->set('aircrafts',$aircrafts);
.... and so on....
$this->set('person_properties',$person_properties);
}
function download($id = null) {
$download_link = 'dashboard/view/print:1';
// Include Component
App::import('Component', 'Pdf');
// Make instance
$Pdf = new PdfComponent();
// Invoice name (output name)
$Pdf->filename = 'dashboard-' . date("M");
// You can use download or browser here
$Pdf->output = 'download';
$Pdf->init();
// Render the view
$Pdf->process(Router::url('/', true) . $download_link);
$this->render(false);
}
}
?>
So in my opinion the $Pdf->process call get´s the data by calling more or less the view, but this process is not logged in, or in other words not authorized to get the data i want to render into the pdf. So the question is now how to get it done by not opening my application to everyone.
Best regards, cdjw
Edit:
You could do something like this:
if($this->Session->check('Auth.User')) {
// do your stuff
} else {
// do something else
}
You could check for 2 things before rendering /view:
a valid session (a user is logged in)
a valid security token that you pass from your download action as a named parameter
For the security token, just make up a long random string.
As the PDF is rendered on the same server, the token will never be known in the open and provide sufficient security.
Hope this is a working idea for you.
I had this similar issue, and this is how I handled it...
I first noticed that the process call of the PdfComponent was doing a request from the same server, so I tricked CakePHP on allowing the view only for requests being made from the server itself.. like this:
public function beforeFilter() {
if ($this->request->params['action']=='view'&&$_SERVER['SERVER_ADDR']==$_SERVER['REMOTE_ADDR']) { // for PDF access
$this->Auth->allow('view');
}
}
You should put
$this->Auth->allow('download','view');
inside AppController. rather than place where are you using now.
function beforeFilter() {
$this->Auth->allow('download','view');
....
}
This question is slightly related to my old post Dealing with Alias URLs in CakePHP
After much thought, I am exploring the option of having a custom 404 script in my Cake App, that is reached when a URL does not map to any controllers/actions. This script would check $this->here and look it up in a database of redirects. If a match is found it would track a specific 'promo' code and redirect.
I'm thinking status codes. Can I make my script return a suitable status code based on certain conditions? For example:
URL matches a redirect - return a 301
URL really does not have a destination - return a 404.
Can I do this?
EDIT:
What about this? Anyone see any problems with it? I put it in app_controller.
function appError($method, $params) {
//do clever stuff here
}
This should work. Assuming you redirect 404's at a LegacyUrls::map() controller action. The code needs to be stored in app/app_error.php:
<?php
class AppError extends ErrorHandler{
function error404($params) {
$Dispatcher = new Dispatcher();
$Dispatcher->dispatch('/legacy_urls/map', array('broken-url' => '/'.$params['url']));
exit;
}
function missingController($params) {
$Dispatcher = new Dispatcher();
$Dispatcher->dispatch('/legacy_urls/map', array('broken-url' => '/'.$params['url']));
exit;
}
}
?>
Good luck!
I've always created app\views\errors\missing_action.ctp and app\views\errors\missing_controller.ctp
Cake will automatically display one of those views when a url does not map out to a controller or its methods.
Unless there is a certain need for the error codes that you did not give, this would work perfectly!
I'd like to augment felixge's answer.
This version outputs a 404 error to the browser:
class AppError extends ErrorHandler
{
function _outputMessage($template)
{
if ($template === 'error404') {
$Dispatcher = new Dispatcher();
$Dispatcher->dispatch('legacy_urls/map', array('broken-url' => '/'.$params['url']));
return;
}
parent::_outputMessage($template);
}
}
