I have some custom place holders in layout file, like [Region_Contents]
now I want to replace these placeholders with my custom html as layout is rendered
like instead of displaying [Region_Contents] it may show Hello this is test block
is there any way to do this?
You can use view filters for this. First we have to implement the Zend_Filter_Interface like so:
class My_View_Filter_PlaceholderReplacer implements Zend_Filter_Interface
{
public function filter($value)
{
return str_replace('[Region_Contents]', 'Hello this is test block', $value);
}
}
In the code above, $value contains the string representation of the view just before it is displayed. Whatever is returned by the function above will be used by ZF when rendering the view. Note that we're using str_replace over preg_replace for performance reasons.
Next, we need to tell ZF to use the filter we just made. You can do this in the bootstrap.
class Bootstrap extends Zend_Application_Bootstrap_Bootstrap
{
protected function _initViewSettings()
{
$this->bootstrap('view');
$view = $this->getResource('view');
$view->addFilterPath('My/View/Filter', 'My_View_Filter');
$view->setFilter('PlaceholderReplacer');
...
}
...
}
For more info, please refer to the following links:
Zend Manual
Zend Framework and Translation
If it's not necessary to keep the same syntax you describe above, you might just use the standard Zend_View placeholder view helpers: http://framework.zend.com/manual/en/zend.view.helpers.html#zend.view.helpers.initial.placeholder
Hope that helps,

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,
]);
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.
Zend Framework 1.12
I have written my own view helper and need to call a Zend view helper from within it.
In my view file, I can call
$this->formSelect (...) to get a select dropdown
however in my own view helper file
$this->view->formSelect (...)
causes an error
Call to undefined method Zend_View_Helper_MilestoneList::formSelect()
How can I access Zend Framework view helpers from within there?
It is very simple to call another View Helper.
Your view helper extends must be extend Zend_View_Helper_Abstract, so that it has access to the $view. Then you may simply call helpers as you would from a view, i.e.
$this->view->generalFunctions()->progressMeter();
For example you can access it in to your view:
<?php
class Zend_View_Helper_FormVars extends Zend_View_Helper_Abstract {
/* ... */
public function mkCategoryCodeSelectGroup($codeTypeArr=array(),
$codesArr=array()) {
$html='';
$html. $this->view->generalFunctions()->progressMeter();
return $html;
}
}
Please set class name as per your need. and just try it.
let me know if i can help you
I found that
$selectFormHelper = $this->view->getHelper('FormSelect');
$selectFormHelper->formSelect(...)
works, but
$this->view->formSelect(...)
does not.
I'm not sure why that is, but happy to live with it for now.
I wish to build a form that does not create/update any active records. An example of such a form would be a search filter using check boxes for the user to select which categories to apply to the search.
Everything I read about forms in Yii is centred around the CActiveForm class. What is the Yii way to build forms that don't use active records?
If you want to embrace Yii's convenient form handling, you should use CActiveForm. It does not require CActiveRecord. But it always requires a model for your form data - which is a good thing, because this will keep the validation rules out of your view files. Instead of a CActiveRecord you could also build a simple model class from CFormModel.
class SomeForm extends CFormModel
{
public $name;
public $email;
public function rules()
{
return array(
array('name,email','required'),
array('email','email'),
);
}
}
Check the docs of the CHtml class. While it contains all the active* method, there are plain form methods in there as well, such as checkBox() or checkBoxList() that sound like what you're looking for.
I want to add some javacsript to a Zend_Form_Element_Text .
At first I thought a decorator would be the best way to do it, but since it is just a script (the markup doesn't change) then maybe a view helper is better? or a view script?
It seems like they are all for the same purpose (regarding a form element).
The javascript I want to add is not an event (e.g. change, click, etc.). I can add it easily with headScript() but I want to make it re-usable , that's why I thought about a decorator/view helper. I'm just not clear about the difference between them.
What is the best practice in this case? advantages?
UPDATE: Seems like the best practice is to use view helpers from view scripts , so decorators would be a better fit?
Thanks.
You could create your own decorator by extending Zend_From_Decorator_Abstract and generate your snippet in it's render() method :
class My_Decorator_FieldInitializer extends Zend_Form_Decorator_Abstract {
public function render($content){
$separator = $this->getSeparator();
$element = $this->getElement();
$output = '<script>'.
//you write your js snippet here, using
//the data you have in $element if you need
.'</script>';
return $content . $separator . $output;
}
}
If you need more details, ask for it in a comment, i'll edit this answer. And I didn't test this code.
Use setAttrib function.
eg:-
$element = new Zend_Form_Element_Text('test');
$element->setAttrib('onclick', 'alert("Test")');
I'm not actually seeing where this needs to be a decorator or a view-helper or a view-script.
If I wanted to attach some client-side behavior to a form element, I'd probably set an attribute with $elt->setAttrib('class', 'someClass') or $elt->setAttrib('id', 'someId'), some hook onto which my script can attach. Then I'd add listeners/handlers to those targeted elements.
For example, for a click handler using jQuery , it would be something like:
(function($){
$(document).ready(function(){
$('.someClass').click(function(e){
// handle the event here
});
});
})(jQuery);
The benefit is that it is unobtrusive, so the markup remains clean. Hopefully, the javascript is an enhancement- not a critical part of the functionality - so it degrades gracefully.
Perhaps you mean that this javascript segment itself needs to be reusable across different element identifiers - someClass, in this example. In this case, you could simply write a view-helper that accepts the CSS class name as the parameter.
"the markup doesn't change", Yap,
but I like to add some javascript function throw ZendForm Element:
$text_f = new Zend_Form_Element_Text("text_id");
$text_f->setAttrib('OnChange', 'someFunction($(this));');
The best way is if you are working with a team, where all of you should use same code standard. For me and my team this is the code above.
