}
this is my script and my problem is that I have a categoryList array, its is only getting in edit view. I want to use that category list on newaction. When I tried to foreach that array in new action view file it is getting empty. and i can get it after saving the postObject. Any idea about this particular problem? and variable test from newaction also not visible in the newAction Template file.
Am using Typo3 7.6.11
Declare arguments you want to receive, as arguments for your controller action. Reference this argument name correctly in Fluid templates when you build links to your controller action. Do not access arguments from the Request directly. Add correct PDPdoc comments for it, too.
Basically: do the correct thing with your arguments instead of bypassing the framework. This advise applies to anything you do in Extbase.
NB: New and Edit actions should never, ever share the same template (this further indicates you bypass the framework's expected behavior). Create and New, yes. But not New and Edit. If necessary, put the form fields in a partial and the form itself in separate templates so you can control the action building and object/object-name setup correctly.
If a $this->***Repository method returns NULL, it may be that the repository had no StoragePid defined.
Make sure both newAction and editAction have the same storagePid defined in TypoScript or your Backend Plugin Settings (Flexform).
The TypoScript for this would look something like this:
plugin.tx_extension.persistence.storagePid = 100

I want to use the view template of the list action for my listByYear action. I tried setTemplatePathAndFilename without success. It still cannot find the template.
Sorry, the requested view was not found.
The technical reason is: No template was found. View could not be
resolved for action "listByYear" in class
"XXX\YYY\Controller\EventController".
/**
* action listByYear
* #param \XXX\YYY\Domain\Model\Event $event
*
* #return void
*/
public function listByYearAction(\XXX\YYY\Domain\Model\Event $event)
{
$date = $event->getStart();
$events = $this->eventRepository->findByYear($date->format('Y'));
$this->view->setTemplatePathAndFilename(
'typo3conf/ext/' .
$this->request->getControllerExtensionKey() .
'/Resources/Private/Templates/Event/List.html'
);
debug('typo3conf/ext/' .
$this->request->getControllerExtensionKey() .
'/Resources/Private/Templates/Event/List.html');
$this->view->assign('events', $events);
}
How do I make it use the template for the list?
The very short answer is, you can't. The view will already have been initialised and asked to resolve a template well before your action fires, indeed well before any point where you can affect the template filename that it would look for.
The template file that by convention would be resolved must always exist. This is what allows your controller action to render. You can then, but I would not recommend that you do, override the template file by setting the template name (the action).
Overall recommendation: use the default template naming logic. If you need to re-use templates, consider refactoring the template parts you need to reuse, placing them in partial templates.
// Do not forget the use in the header ...,
// or write fully qualified class path..
use TYPO3\CMS\Core\Utility\GeneralUtility;
use TYPO3\CMS\Fluid\View\StandaloneView;
// then add something like this in your action before the assign...
// or maybe create a Standalone view: search the web for "Extbase Standaloneview"
// have a look at: /typo3/sysext/about/Classes/Controller/AboutController.php
$this->view = GeneralUtility::makeInstance(StandaloneView::class);
$this->view->setTemplate('ActionName');
$this->view->setTemplateRootPaths(['EXT:your_ext/Resources/Private/Templates']);
$this->view->setPartialRootPaths(['EXT:your_ext/Resources/Private/Partials']);
$this->view->setLayoutRootPaths(['EXT:your_ext/Resources/Private/Layouts']);
$this->view->assignMultiple([
'whatever' => $whatever,
'youLike' => $youLike,
]);
I wrote a very simple extension in typo3 v7.6.11 with the extension builder where a visitor can ask for a taxi-ride.
everything works, only that I need to make the request more appealing by asking the pick-up point and the drop-off point ... that request goes to the actual form like this in the template (requestPid is the id of the page with the form):
<f:form pageUid="{settings.additional.requestPid}" action="form" name="request" object="{Request}">
<f:render partial="Ticket/RequestNewFields" />
<f:form.submit value="{f:translate(key: 'tx_wmnltickets_domain_model_ticket.admin.continue')}" />
</f:form>
but the formAction in the controler doesn't actually ask anything from the model (getArguments() I tried);
/**
* action form
*
* #return void
*/
public function formAction() {
$this->request->getArguments();
}
the request does send the $_POST but I see no way to get it into the form ...
if you'd like to see more code to understand, just ask, I don't know what you'd be looking for ...
Your form action should has the request parameter from you form:
/**
* action form
*
* #param array $request
*
* #return void
*/
public function formAction($request) {
}
Then you can access the data with $request['origin']
I'm not sure if the variable $request is allowed as argument. Maybe you must rename it in the function and in your fluid template if it doesn't work.
Did you create the extension with the builder? The easiest way is to create the fields (pickup-point, dropoff-point) in the builder, then create a createAction or newAction (not sure how it is called in the builder). It will create the template for the createAction where you can just copy/paste the <f:form...
There is a way to access directly POST/GET parameters (It is not recomended to use it directly when you can make it with the clean extbase way):
$myVar = \TYPO3\CMS\Core\Utility\GeneralUtility::_GP('myVar');
Using the infos in this link:
https://docs.typo3.org/typo3cms/ExtbaseFluidBook/8-Fluid/9-using-php-based-views.html
I try to create an action to output a JSON.
I have a normal controller with the list action:
public function listAction()
{
$storelocators = $this->storelocatorRepository->findAll();
$this->view->assign('storelocators', $storelocators);
}
And in ext/my_storelocator/Classes/View/Storelocator I have a class List.php:
<?
class Tx_MyStorelocator_View_Storelocator_List extends Tx_Extbase_MVC_View_AbstractView {
public function render() {
return 'Hello World';
}
}
All I get is:
Sorry, the requested view was not found.
The technical reason is: No template was found. View could not be resolved for action "list" in class "My\MyStorelocator\Controller\StorelocatorController".
So I guess there is something wrong with the paths. Or where is the Problem?
Edit: Extensioninfos
Vendor: My
key: my_storelocator
controller: NOT SURE (I created it with the extension_builder so I guess my controllers name is Storelocator)
action: list
From my understanding a classname like Tx_MyStorelocator_View_Storelocator_List should be correct. But its not working
You will need to create an empty file for the HTML view for your controller, e.g. Resources/Private/Template/Storelocator/List.html, even if you do not plan to use the HTML view or if you just return the content yourself (which is perfectly fine).
The reason for this is simply technical limitation.
First of all, TYPO3 now has a built-in JSON view, described thoroughly here: https://usetypo3.com/json-view.html. It lets you easily define which properties you'd like to render.
The error message means that your Controller is still pointing to the TemplateView - because thats the error the TemplateView throws if it can't find the defined template file.
You can specify which view to use to render within your controller. You can either set a default view via the $defaultViewObjectName property, like so:
/**
* #var string
*/
protected $defaultViewObjectName = '\TYPO3\CMS\Fluid\View\TemplateView';
You can also set it from within the Controller inside initialization actions like so:
public function initializeExportPDFAction(){
$this->defaultViewObjectName = 'Vendor\Extension\View\FileTransferView';
}
(I have, however, not yet found a way to define the template from within actions, any tips in the comments would be appreciated)
Your path syntax is probably out of date. Instead of writing a render() function in Classes/View/Storelocator/List.php, try writing a listAction() function in a Classes/Controller/StorelocatorController.php file. Extension Builder should have created this file for you, if you made an aggregate model with the usual "list, create, edit ..." and such actions.
Review A journey through the Blog Example and the following chapter, Creating a first extension, for tips.
Keep in mind that there is a mismatch between the documentation and the Extension Builder generated PHP code files. Developing TYPO3 Extensions with Extbase and Fluid has some parts up to date, and other parts still using old syntax.
When I render a form, form Filed Name is given as an array. For example: search[item], search[keyword] etc. where search is name of the form.
I'm not great on working with forms but I think, the name should be rendered as simply, name="item" or name="keyword".
I've looked at all the documentation, customizing form rendering topic etc. but I can't find any way to change the default behaviour of Symfony form to render form filed name from 'search[item]' to 'item'.
This way, when I ask for the POST data, I can ask simply $this->getRequest()->request->get('item'), as I have to deal with lots of individual parameters.
Help would be great i) To figure out how to achieve what I want. ii) to let me know, why the name is rendered this way. is this the good practice?
Rather than accessing parameters from the Request object, you can bind the Request object to the form.
For example, in your controller method that you post your form to:
namespace Acme\Controller;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Acme\Form\MyFormClass;
class MyFormController extends Controller
{
receiveFormAction(Request $request)
{
$form = new MyFormClass();
// you can specify that a route only accepts a post
// request in the routing definition
if ($request->isMethod('POST')) {
// this populates the form object with the data
// from the form submission
$form->bind($request);
if ( ! $form->isValid()) {
throw new \Exception('Invalid form');
}
// an array of the data the format you require
$data = $form->getData();
$data['item'];
$data['keyword'];
// etc.
}
}
}
The above is the way you should be handling forms in Symfony 2, and is how you can leverage the power that the forms component gives you, with validation etc.
Symfony supports multiple forms on a page. They might be instances of the same form or have similar field names. Having the fields for each form all together in an array makes this easy to do.
So, I have a form for editing blog articles.
Among other things I need to be able to edit article tags. They are stored as ArrayCollection inside my Blog entity. (ManyToMany cascade: persist,remove)
Now, Simfony handles this type of data with <select> tag and it works just fine for selecting, but I want to be able to remove and add tags too.
This is also possible and is very well explained in this Cookbook article: How to Embed a Collection of Forms
However, result of this tutorial is still not very elegant and I would love to have input box similar to StackOverflow tag box.
Since there are many already done solutions under free licences I decided to just use one of them, for example jQuery Tags Input.
Basically, all I need to do is run $('#tags_input_box').tagsInput() and it transforms it into SO-like tag box.
Now, I'm searching for the easiest way to bind some custom made input to my form and submit it back together with the rest of 'genuine' fields in a shape that will be understood by Symfony2.
Could anyone refer me to some document or give me some starting info where I should begin my research on this matter ?
It appears that plugin sends it in as a comma-separated string value.
Probably the easiest way would be to simply treat it as a single input in your form, and then split it up when you process the form.
// Entity to hold it in string form.
namespace Some\Entity;
class TagStringEntity {
protected $tagString;
// getTagString and setTagString
}
// Custom form type.
// Use this AbstractType in your form.
namespace Some\Form;
Symfony\Component\Form\AbstractType;
class TagType extends AbstractType {
public buildForm(FormBuilder $builder, array $options) {
$builder->add('tagString'); // will default to text field.
}
}
// In Controller
public function displayFormAction() {
// Join the tags into a single string.
$tagString = implode(',', $article->getTags()); // assuming it returns an array of strings.
$tagStringType = new TagStringType();
$tagStringType->setTagString($tagString);
// build form, etc...
}
public function checkFormAction() {
// ...
if ($form->isValid()) {
// Get the tag string, split it, and manually create your separated tag objects to store.
}
}
That's probably the cleanest and simplest way to do it using that jQuery plugin. Takes a bit of working around since you are turning multiple items into many and vice versa, but not too bad.
