ZF2 : disable error page layout - model-view-controller

im trying to disable layout while showing error/exception page in my zf2 module
but nothing works
please help

Final Solution in my Module.php
$eventManager = $e->getApplication()->getEventManager();
$eventManager->attach(MvcEvent::EVENT_DISPATCH_ERROR, function($e) {
$result = $e->getResult();
$result->setTerminal(TRUE);
});
it works and only loads error/404 view file not the layout file
thanks andrew

If you look at the Zend Framework 2 MVC module you will see possibilities for this..
DispatchListener.php
try {
$return = $controller->dispatch($request, $response);
} catch (\Exception $ex) {
$e->setError($application::ERROR_EXCEPTION)
->setController($controllerName)
->setControllerClass(get_class($controller))
->setParam('exception', $ex);
// look here...
$results = $events->trigger(MvcEvent::EVENT_DISPATCH_ERROR, $e);
$return = $results->last();
if (! $return) {
$return = $e->getResult();
}
}
You can see they MvcEvent which is triggered when you have an exception thrown inside the controller, there's a few other processes attaching to this event.
You could attach a method to this event and do what ever you want.
As an example look at ExceptionStrategy.php
public function prepareExceptionViewModel(MvcEvent $e)
{
....
}

this is not your ans but it will help to other
in zf2
public function indexAction()
{
echo "json"
return $this->getResponse();
}

The easiest way is to use config config/autoload/local.php
return array(
'view_manager' => array(
'display_exceptions' => false
)
);
Adding this lines disables exceptions. In addition you can use your own local.php on a dev server.

API REST don't work routes

I'm using codeigniter, for make an api rest, with the library that provide the oficial web site.
The problem is: the file routes.php doesn't redirect well. When i put localhost/API/1 into my browser apear the 404 error.
Here my controller "Apicontroller":
public function __construct() { //constructor //no tocar
parent::__construct();
$this -> load -> model("Modelocontrolador");
}
public function index_get() { //get all the info
$datos_devueltos = $this->Modelocontrolador->getPrueba(NULL, "Usuarios");
if(!is_null($datos_devueltos)){
$this->response(array("response" => $datos_devueltos), 200);
}else{
$this->response(array("response" => "No date"), 200);
}
}
public function find_get($id){ //select where
$datos_devueltos = $this->Modelocontrolador->getPrueba($id, "Usuarios");
if($id != NULL){
if(!is_null($datos_devueltos)){
$this->response(array("response" => $datos_devueltos), 200);
}else{
$this->response(array("response" => "No date"), 200);
}
}else{
$this->response(array("response" => "No dates for search"), 200);
}
}
public function index_post() { //insert in la table
if(! $this -> post("dato")){
$this->response(array("response" => "No enought info"), 200);
}else{
$datoID = $this -> Modelocontrolador -> save($this -> post("dato"),"UsuariosJJ");
if(!is_null($datoID)){
$this->response(array("response" => $datoID), 200);
}else{
$this->response(array("response" => "No found it"), 200);
}
}
}
public function index_put($id) { //"update"
if(! $this -> post("dato") || ! $id){
$this->response(array("response" => "No ha mandado informacion correcta para el update"), 200);
}else{
$datoID = $this -> Modelocontrolador -> update("Uid",$id,$this -> post("dato"),"UsuariosJJ");
if(!is_null($datoID)){
$this->response(array("response" => "Dato actualizado"), 200);
}else{
$this->response(array("response" => "Error modify"), 200);
}
}
}
public function index_delete($id) {
if(! $id){
$this->response(array("response" => "Not enought info"), 200);
}else{
$delete = $this-> Modelocontrolador -> delete("Uid",$id,"UsuariosJJ");
}
if(!is_null($delete)){
$this->response(array("response" => "Date delete"), 200);
}else{
$this->response(array("response" => "Error delete"), 200);
}
}}
And my routes file:
$route['default_controller'] = 'Apicontroller';
$route['404_override'] = '';
$route['translate_uri_dashes'] = FALSE;
/*sub-rutas*/
/*---------*/
$route["Apicontroller"]["get"] = "Apicontroller/index"; //basico
$route["Apicontroller/(:num)"]["get"] = "Apicontroller/find"; //select
$route["Apicontroller"]["post"] = "Apicontroller/index"; //insert
$route["Apicontroller/(:num)"]["put"] = "Apicontroller/index/$1"; //update
$route["Apicontroller/(:num)"]["delete"] = "Apicontroller/index/$1"; //delete
If the browser request literally uses /API then routing needs to 'see' exactly that. Also, the route rules must be explicit with the method to be called. (Hopefully the code shown reflects the mapping you had in mind.)
/*sub-rutas*/
/*---------*/
$route["API"]["get"] = "Apicontroller/index_get"; //basico
$route["API/(:num)"]["get"] = "Apicontroller/find_get/$1"; //select
$route["API"]["post"] = "Apicontroller/index_post"; //insert
$route["API/(:num)"]["put"] = "Apicontroller/index_put/$1"; //update
$route["API/(:num)"]["delete"] = "Apicontroller/index_delete/$1"; //delete
Using the above routes I created some test code. Here are those files.
The much simplified Apicontroller.
class Apicontroller extends CI_Controller
{
function __construct()
{
parent::__construct();
}
function index_get()
{
echo "API index";
}
public function find_get($id)
{ //select where
echo "API find_get $id";
}
public function index_post()
{
echo 'API index_post';
}
public function index_put($id)
{ //"update"
echo "API put $id";
}
}
I don't believe that because your Apicontroller is extending a different Class the results would change. That may be a drastic assumption.
In order to test POST calls I used these two files.
First a Testpost.php controller
class Testpost extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->load->helper('form');
}
public function index()
{
$this->load->view("test");
}
}
The very simple view (test.php) loaded by the above.
<?php
echo form_open("API");
echo form_submit('mysubmit', 'Submit Post!');
echo form_close();
Directing the browser to localhost/testpost shows a page with a single submit button. Pressing the button results in a screen with the text "API index_post".
Sending the browser to localhost/API/3 produces a screen with the text "API find_get 3".
localhost/API produces "API index".
Now the interesting thing (not related to your problem, but interesting).
Given the default
$route['default_controller'] = 'Apicontroller';
and the route
$route["API"]["get"] = "Apicontroller/index_get";
I expected that directing the browser to the home page localhost would produce "API index". But it doesn't. It results in a 404. Due to that behavior it might be wise to be more explicit with default_controller
$route['default_controller'] = 'Apicontroller/index_get';
Or add an index() function to Apicontroller that calls $this->index_get().
I did not test PUT or DELETE as my server isn't setup to handle them. But as GET and POST seem to function, in a righteous world, they will work.
seems like you are using PHil's REST_Controller library with CI 2.x, correct ?
If so, I would recommend you to use what I like to call an "index gateway" because you can't do per-Method routing with CI2:
class Apicontroller extends REST_Controller
{
function index_gateway_get($id){
$this->get_get($id);
}
function index_gateway_put($id){
$this->put_put($id);
}
// This is not a "gateway" method because POST doesn't require an ID
function index_post(){
$this->post_post();
}
function get_get($id = null){
if(!isset($id)){
// Get all rows
}else{
// Get specific row
}
}
function put_put($id = null){
if(!isset($id)){
// a PUT withtout an ID is a POST
$this->post_post();
}else{
// PUT method
}
}
function post_post(){
// POST method
}
}
The routing to make this work is really easy:
$route["API/(:num)"] = "Apicontroller/index_gateway/$1";
That's all you need. Phil's REST Library will redirect to the correct index_gateway_HTTPMETHOD depending on which method is used.
Each index_gateway_HTTPMETHOD will then redirect to the correct method.
As far as I know, this trick is the only way to have CI2 use a single /API/ entry point that works for all HTTP Methods.

How to change existing tag information in Magento

I am trying to update the popularity count of Magento's Tag module by interacting with this core function in Mage_Tag_Model_API
public function update($tagId, $data, $store)
{
$data = $this->_prepareDataForUpdate($data);
$storeId = $this->_getStoreId($store);
/** #var $tag Mage_Tag_Model_Tag */
$tag = Mage::getModel('tag/tag')->setStoreId($storeId)->setAddBasePopularity()->load($tagId);
if (!$tag->getId()) {
$this->_fault('tag_not_exists');
}
// store should be set for 'base_popularity' to be saved in Mage_Tag_Model_Resource_Tag::_afterSave()
$tag->setStore($storeId);
if (isset($data['base_popularity'])) {
$tag->setBasePopularity($data['base_popularity']);
}
if (isset($data['name'])) {
$tag->setName(trim($data['name']));
}
if (isset($data['status'])) {
// validate tag status
if (!in_array($data['status'], array(
$tag->getApprovedStatus(), $tag->getPendingStatus(), $tag->getDisabledStatus()))) {
$this->_fault('invalid_data');
}
$tag->setStatus($data['status']);
}
try {
$tag->save();
} catch (Mage_Core_Exception $e) {
$this->_fault('save_error', $e->getMessage());
}
return true;
}
In my controller I have this :
public function clickAction()
{
$tagString = $this->getRequest()->getParam('tag');
$tagByName = Mage::getModel('tag/tag')->loadByName($tagString);
$tagId = $tagByName->getTagId();
$basePopularity = ['base_popularity' => '13']; // hard coding while testing
Mage::getModel('tag/api')->update($tagId, $basePopularity, 1);
}
If I put a log statement in this part of the update function :
try {
// log stuff
$tag->save();
}
I can see it makes it to that try but there is no change in the data. What did I screw up? Any other ideas on how I can update the popularity of a tag through a controller? Using this same method and adding 'name' => 'blah' to that $data array parameter works fine..
I also found in Mage_Tag_Model_Indexer_Summary.php this method defined in the PHPdoc * #method Mage_Tag_Model_Indexer_Summary setPopularity(int $value) Maybe that is what I need... can someone provide an example showing how I could use that magic setter?
Try adding Mage::app()->setCurrentStore(Mage_Core_Model_App::ADMIN_STORE_ID); at the start of your clickAction function. base_popularity can only be updated from admin store.

Validating POPO's with Symfony2

I am trying to validate parameters with Json-RPC. With Symfony2 validation I can do this:
$expense = new Expense;
$expense->setAmount(1);
$validator = $this->get('validator');
$errors = $validator->validate($expense);
But I do not want to manually specify each parameter with the setFoo() method. Is there anyway to bind the data similar to how the Symfony Form library works?
If I understand your question, $errors = $validator->validate($user) will do the job. See using the validator service documentation.
Turns out this is not possible with Symfony2. You will have to bind the data yourself. I created a bind method similar to this:
$params = array('amount' => 1);
foreach($params as $key => $value) {
try {
$path = new PropertyPath($key);
$path->setValue($obj, $value);
} catch (\Exception $e) {
// parameter does not exist in POPO
}
}
After you bind your parameters to the POPO object, you can validate it normally.

How to disable render view in zend framework 2?

I want to use some ajax, but I don't know how to use function as the same as setNoRender() in zend framework 2 to disable for render view.
How to disable rendering view in zend framework 2?
To disable your view :
public function myactionAction()
{
// your code here ...
return false;
}
"return false" disables the view and not the layout! why? because the accepted types are:
ViewModel
array
null
so "false" disable the view.
To disable layout and view, return a response object:
public function myactionAction()
{
// your code here ...
return $this->response;
}
To disable layout:
public function myactionAction()
{
// your code here ...
$view = new ViewModel();
$view->setTerminal(true);
return $view;
}
If you're using JSON, then look at the view's JsonStrategy and return a JsonModel from you controller. See this article.
Alternatively, you can return an Response from your controller and the whole view layer is skipped:
public function testAction()
{
$response = $this->getResponse();
$response->setStatusCode(200);
$response->setContent('foo');
return $response;
}
Proper and simple solution to do this
public function testAction()
{
$data = array(
'result' => true,
'data' => array()
);
return $this->getResponse()->setContent(Json::encode($data));
}
Details: http://cmyker.blogspot.com/2012/11/zend-framework-2-ajax-return-json.html
I found some answer.
Though $this->layout()->getLayout() returns the name/path of the newly selected layout... The layout does not change with any of the following commands...
within a controller
$this->getLocator()->get('view')->layout()->setLayout('layouts/ajax.phtml');
$this->getLocator()->get('view')->layout()->setLayout('ajax');
$this->getLocator()->get('view')->layout()->disableLayout();
within a view PHTML file
$this->layout()->setLayout('layouts/ajax.phtml');
$this->layout()->setLayout('ajax');
$this->layout()->disableLayout();
$view = new ViewModel();
$view->setTerminate(true);
...
use Zend\View\Model\JsonModel;
public function myAction() {
...
$view = new JsonModel($myArray);
$view->setTerminal(true);
return $view;
}

codeigniter validate

Hello I have a forum and when a user creates a comment, I want that if he didn't type anything I want to show him an error that he must type something in :) but I dont know how to put him the the thread he is in.
I have this
if($this->_submit_validate_comment() == false) {
$this->post(); return;
}
function _submit_validate_comment() {
$this->form_validation->set_rules('kommentar', 'kommentar', 'required|min_length[4]');
return $this->form_validation->run();
}
You could do this with jquery but if that is not an option you could get the forum or topic id from the url (assuming your are using the url this way).
For example:
http://yoursite.com/forum/topic/12
if($this->_submit_validate_comment() == false)
{
$topic_id = $this->uri->segment(3);
redirect('/forum/topic/'. $topic_id);
}
Or
if($this->_submit_validate_comment() == false)
{
$topic_id = $this->uri->segment(3);
$this->topic($topic_id);
}
Hope this helps.
Thanks for helping i can see what you mean but it just dont work :b,
i have this
$topic_id = $this->uri->segment(3);
$this->post($topic_id);
return;
and my url is
localhost:8888/ci/index.php/forum/create_comment
it looks like it cant find the ID
my URL to the forum is
localhost:8888/ci/index.php/forum/post/33
this is my functions
function create_comment() {
if($this->_submit_validate_comment()
== false) { $id = $this->uri->segment(3);
$this->post($id); return;
//echo "validate fejl, kontakt lige
en admin!"; } else { $data =
array( 'fk_forum_traad' =>
$this->input->post('id'),
'brugernavn' =>
$this->session->userdata('username'),
'indhold' =>
$this->input->post('kommentar'),
'dato' => 'fejl' );
$this->load->model('forum_model');
$this->forum_model->create_comment($data);
redirect('/forum/post/'.
$this->input->post('id').'',
'refresh'); }
}
function post($id) {
$this->load->model('forum_model');
$data['query'] =
$this->forum_model->posts($this->uri->segment(3));
$this->load->model('forum_model');
$data['comments'] =
$this->forum_model->comments($this->uri->segment(3));
$data['content'] = 'forum_post_view';
$this->load->view('includes/template',
$data); }
Why not pass in the return uri in the form submission using a hidden input field? No additional work will be needed by the controller other than validation of the return uri before performing a redirect.
Place the validation error string in session class's flashdata for echoing out in the form, along with any other data used to pre-populate your form)
