Symfony EasyAdminBundle - How to add a custom action in entity form? - php

I am using EasyAdminBundle in Symfony 3.1.9.
I managed to customize actions in lists, as well explained here:
https://github.com/javiereguiluz/EasyAdminBundle/blob/master/Resources/doc/tutorials/custom-actions.md
But I didn't found any documentation to add custom entity action in forms.
My goal is to add, near the "Save", "Delete" and "Back to list" buttons, a button which saves current entity and redirect to the current edit form (not return to list as default behavior).
entity form edit actions
Thank you in advance

I've probalby made something dirty but it works.
I've overwrited the editAction :
public function editAction()
{
$response = parent::editAction();
if ($response instanceof RedirectResponse) {
$request = Request::createFromGlobals();
return $this->redirect(urldecode($request->request->get('referer')));
}
return $response;
}
The method $this->getCurrentEntity() were unknown.
I've also overwrited the edit.html.twig to add another button next to the basic one with jQuery:
var cloned = $( "button.action-save" );
var clone = cloned.clone();
cloned.after(clone);
clone.addClass('action-save-stay')
clone.html('<i class="fa fa-save"></i>{{ 'action.save_stay'|trans }}');
$('.action-save-stay').bind('click', function(e) {
e.preventDefault();
$('input[name="referer"]').val(window.location.href);
$('form').submit();
});
It changes the hidden input named referer.
By default, easyadmin redirects to the referer contained in the query string.
Thank you so much to put me in the right direction.

Olivier If your goal is just to redirect back to edit action of same entity form instead of redirection to list action. It's quite simple like this. Let's assume You are on new action of Product entity and want back to edit after saving new product.
public function newProductAction()
{
$response = parent::newAction();
if ($response instanceof RedirectResponse) {
$entity = $this->getCurrentEntity();
return $this->redirectToRoute('admin', [
'entity' => 'Product',
'action' => 'edit',
'id' => $entity->getId()
'menuIndex' => 1
]);
}
return $response;
}
Here 2 points keep in mind menuIndex is for active menu class so, it may be changed as per your sequence. And redirect route 'admin' should be your easyadmin backend route.

Is this the correct way to handle forms in two pages?

I have an index page which contains a simple form; if the form validation fails the index page is reloaded with errors if not then the action related to the page forwards the request to another action related to page success. The success page uses the form submitted to create a list from DB. Once we are on success page we have another form similar to the first one which the user can use to modify the list on the page. Both forms have same fields.
index page action:
class DefaultController extends Controller {
/**
* #Route("/", name="homepage")
*/
public function indexAction(Request $request) {
$event = new Event();
$form = $this->createForm(EventForm::class, $event);
$form->handleRequest($request);
if($form->isSubmitted() && $form->isValid()) {
// Do some minor modification to the form data
$event->setDate($party->getDate()->modify('+12 hours'));
$cityName = strtolower($event->getPlace()['city']);
// We know the form data is valid, forward it to the action which will use it to query DB
return $this->forward('AppBundle:Frontend/Default:eventsList', array('request' => $request));
}
// If validation fails, reload the index page with the errors
return $this->render('default/frontend/index.html.twig', array('form' => $form->createView()));
}
success page action (where the form data gets forwarded)
/**
* #Route("/success", name="eventList")
*/
public function eventsListAction(Request $request) {
$event = new Party();
// Create a form in the second page and set its action to be the first page, otherwise form submition triggers the FIRST action related to page index and not the one related to page success
$form = $this->createForm(EventForm::class, $event, array('action' => $this->generateUrl('eventList')));
$form->handleRequest($request);
if($form->isSubmitted() && $form->isValid()) {
$event->setPlace($form["place"]->getData());
$event->setTitle($form["title"]->getData());
$repository = $this->getDoctrine()
->getRepository('AppBundle:Event');
// ....
// Create a list of events using the data from DB
// ....
return $this->render('default/frontend/success.html.twig',
array('events' => $events, 'form' => $form->createView())
);
}
return $this->render('default/frontend/success.html.twig', array('form' => $form->createView()));
}
Although the above implementation "works" I have a couple of issues:
When I submit the first form the url stays the same, that of the first page like:
[HOST]/app_dev.php?place=London&Date=......
But if I submit the second form the URL is correctly:
[HOST]/app_dev.php/success?place=London&date=.....
The implementation feels hacky to me, is there a cleaner way to achieve this?
When the form is submitted, then it's porcessed with the same controller and action. You have to process the submited data and then redirect to success page.
So in your example:
if($form->isSubmitted() && $form->isValid()) {
...
...
return $this->redirectToRoute('eventList');
}
And if you need to transfer posted data from one "page" to another, then you have to store it in session $this->get('session')->set('name', val); and then retrieve data from session in eventList action by $this->get('session')->get('name');

Submit form to another controller in Symfony

I have a page index.html.twig which contains a Form this form when submitted, get validated and the result is shown in a page success.html.twig. Now I have a new requirement where the page success.html.twig itself contains a Form which should contain the values which were passed by the form from index.html.twig and if the user wants the new form should also allow the user to do search directly from success.twig.html. The requirement is inspired by hostel world.
Questions:
Is there a design pattern which I could use to implement a solution
My current thinking is to create a new Action for success.html.twig and submit the form to thatAction instead of rendering success.html.twig from index.html.twig's Action. Is it correct? How can I implement it?
Code (Partial):
/**
* #Route("/", name="homepage")
*/
public function indexAction(Request $request)
{
$event = new Event();
$form = $this->createForm(MyForm::class, $event);
$form->handleRequest($request);
if($form->isSubmitted() && $form->isValid()) {
$event->setPlace($form["place"]->getData());
$event->setDate($form["date"]->getData()->modify('+12 hours'));
return $this->render('default/frontend/success.html.twig',
array('events' => $events, 'cityName' => $cityName, 'cityImage' => $cityImage)
);
}
return $this->render('default/frontend/index.html.twig', array('form' => $form->createView()));
}
It makes sense to have two different actions - at least for different request types (GET, POST, etc..)
There is just one thing as advice: $form->isValid() has already an isSubmitted() check inside. So there is no need to check whether it is submitted or not.

How to connect a form into another phtml view in Zend 2 framework

I am new at Zend2:
I have a form, and in the first stage I create a new ViewModel and return it:
return new ViewModel(array('form' => $form, 'messages' => $messages));
In the post stage when the data comes back from the browser, how can I connect this same form to a new View (which has the same elements maybe less, maybe more) or create another form and rassign it the old form's data and relate it to a new view to show?
Any help would be appreciated.
EDIT:
I tried to do the following:
$form->setAttribute('action', $this->url('auth/index/login-post.phtml'));
But still shows the old one.
When I do this:
return $this->redirect()->toRoute('auth/default', array('controller' => 'index', 'action' => 'login-post'));
I get error page: The requested controller was unable to dispatch the request.
When I get the post of the request I need to load another view, I mean how do I specify which view is connected to which form?
The forms do not themselves have any knowledge of the view. If you wish to change the view after completing the form submission; where this new view provides perhaps a different form, this is something that should be done within the controller.
A (non-working) example with a few options on how a different view could be returned.
class FooController extends AbstractActionController
{
public function getFooForm()
{
return $this->getServiceLocator()->get('Form\Foo');
}
public function getBarForm()
{
return $this->getServiceLocator()->get('Form\Bar')
}
public function fooAction()
{
$request = $this->getRequest();
$form = $this->getFooForm();
if ($request->isPost()) {
$form->setData($request->getPost());
// Is the posted form vaild
if ($form->isValid()) {
// Forms validated data
$data = $form->getData();
// Now there are a few options
// 1. Return a new view with the data
$view = new ViewModel($data);
$view->setTemplate('path/to/file');
return $view;
// OR Option 2 - Redirect
return $this->redirect()->toRoute('bar', $someRouteParams);
// Option 3 - Dispatch a new controller action
// and then return it's view model/response
// We can also pass on the posted data so the controller
// action that is dispathed will already have our POSTed data in the
// request
$request->setPost(new \Zend\Stdlib\Parameters($data));
return $this->forward()->dispatch('App\Controller\Foo', array('action' => 'bar'));
}
}
// Render default foo.phtml or use $view->setTemplate('path/to/view')
// and render the form, which will post back to itself (fooAction)
return new ViewModel(array('form' => $form));
}
public function barAction()
{
$request = $this->getRequest();
$form = $this->getBarForm();
if ($request->isPost()) {
$form->setData($request->getPost());
// ....
}
// Renders the bar.phtml view
return $this->viewModel(array('form' => $form));
}
}
From what I understand form your question, you would need to be using option 3 as the new view should populate a second form with it's already validated data.
If you are referring to something like an edit view then you just need to bind your object to the form.
$form->bind($yourObject);
http://zf2.readthedocs.org/en/latest/modules/zend.form.quick-start.html#binding-an-object
Otherwise you can make the form post to any controller action using by setting it:
$form->setAttribute('action', $this->url('contact/process'));
Maybe post what code you have and more specifics and I'm sure you will get some more detailed answers

Symfony2 - How to render a view from another controller

I have two controllers, homepage and Security.
In the homepage, I am displaying one view and in the security, I am doing some things, and one of them is the email address validation.
What I would like is that when the email validation code is not valid, display the homepage with a flash message. For that, I will have to render the indexAction of the HomepageController, from the Security controller, by giving him as parameter the flash message.
How can this be done? Can I render a route or an action from another controleller?
Thank you in advance.
I believe the checking should not be done in the Security controller. Right place in my opinion is a separate validator service or right in the entity which uses the email address.
But to your question, you can call another controller's action with $this->forward() method:
public function indexAction($name)
{
$response = $this->forward('AcmeHelloBundle:Hello:fancy', array(
'name' => $name,
'color' => 'green',
));
return $response;
}
The sample comes from symfony2 documentation on: http://symfony.com/doc/2.0/book/controller.html#forwarding
I have found the solution, simply use the forward function by specifying the controller and the action nanme:
return $this->forward('MerrinMainBundle:Homepage:Index', array('flash_message'=>$flash_message));
redirectToRoute : Just a recap with current symfony versions (as of 2016/11/25 with v2.3+)
public function genericAction(Request $request)
{
if ($this->evalSomething())
{
$request->getSession()->getFlashBag()
->add('warning', 'some.flash.message');
$response = $this->redirectToRoute('app_index', [
'flash_message' => $request->getSession()->getFlashBag(),
]);
} else {
//... other logic
}
return $response;
}

Symfony2 form submitting on page refresh

I have a form in Symfony2 framework. On successful submission of the page it renders another twig template file and returns the values by passing the parameters in an array. But after submission, if I refresh the page, again it is submitting the form and the table entry is created. Here is the code that is executed after submission in the controller,
$this->get('session')->setFlash('info', $this->get('translator')->trans('flash.marca'));
return $this->render('NewBundle:Backend:marca.html.twig', array(
'active' => 1,
'marca' => $marca,
'data' => $dataCamp,
'dataMarca' => $this->getMarcas($admin->getId()),
'admin' => $admin,
));
I want the form to be redirected to the twig files mentioned there with the parameters and the alert message mentioned above. But I don't want the form to be submitted on page refresh.
Thanks
This worked for me:
return $this->redirectToRoute("route_name");
You should save submitted data in session and redirect user. Then you will be able to refresh page as much as you want without additional submission.
Example code - your action algorithm should be similar:
...
/**
* #Route("/add" , name="acme_app_entity_add")
*/
public function addAction()
{
$entity = new Entity();
$form = $this->createForm(new EntityType(), $entity);
$session = $this->get('session');
// Check if data already was submitted and validated
if ($session->has('submittedData')) {
$submittedData = $session->get('submittedData');
// There you can remove saved data from session or not and leave it for addition request like save entity in DB
// $session->remove('submittedData');
// There your second template
return $this->render('AcmeAppBundle:Entity:preview.html.twig', array(
'submittedData' => $submittedData
// other data which you need in this template
));
}
if ($request->isMethod('POST')) {
$form->bindRequest($request);
if ($form->isValid()) {
$this->get('session')->setFlash('success', 'Provided data is valid.');
// Data is valid so save it in session for another request
$session->set('submittedData', $form->getData()); // in this point may be you need serialize saved data, depends of your requirements
// Redirect user to this action again
return $this->redirect($this->generateUrl('acme_app_entity_add'));
} else {
// provide form errors in session storage
$this->get('session')->setFlash('error', $form->getErrorsAsString());
}
}
return $this->render('AcmeAppBundle:Entity:add.html.twig', array(
'form' => $form->createView()
));
}
Redirect to same page is preventing additional data submission. So lean of this example modify your action and you will be fine.
Also instead save data in session you can pass it through redirect request. But I think this approach is more difficult.
Save your data (session/db/wherever you want it saved)
redirect to a new action, retreiving the new data in that action, and rendering the template
this way, refreshing the new action, will only refresh the template, as the saving of your data happened in the previous action
understand ?
so basically replace your
return $this->render....
by
return $this->redirect($this->generateUrl('ROUTE_TO_NEW_ACTION')));
and in this new action, you put your
return $this->render....
