in my extension i'm using a custom PageTitleProvider for my detail view. It only works when the page is not cached. So i clear the cache then the title will be the name of the record when i reload the page i get the page title. I can't set the action to uncached because of the loading times.
My PageTitleProvider looks like this:
use TYPO3\CMS\Core\PageTitle\AbstractPageTitleProvider;
class CatalogPageTitleProvider extends AbstractPageTitleProvider
{
/**
* #param string $title
*/
public function setTitle(string $title)
{
$this->title = (string)$title.' | '.$GLOBALS['TSFE']->rootLine[0]['title'] ;
}
}
in the Controller i set the title like this:
$search = ['&npsp;', '' ];
$titleProvider = GeneralUtility::makeInstance(CatalogPageTitleProvider::class);
$titleProvider->setTitle( strip_tags(str_replace( $search, '', $service->getName())));
Anyone know if there is something missing or is this a know bug?
Best regards

There was a bugfix about a year ago with the aim to remove the seperate caches for meta tags and page titles: https://git.higidi.com/TYPO3/TYPO3.CMS/commit/44fe4992172ec0e18b28bc4a24c57a5c93b74121
From the bugfix description:
By concept for frontend rendering the page title and meta tags are not
meant to be stored in page cache in order to allow non cachable
plugins to modify those.
Currently both page title and meta tags are stored in separate cache
entries, which violates the concept above and unnecessarily tightly
couples those code parts to the TypoScriptFrontendController and
internal logic of it.
This patch removes these caches.
This fix was introduced in v 9.5.8.
I reverted the script to version 9.5.7 in my project and the page titles are correct again: https://github.com/TYPO3/TYPO3.CMS/blob/v9.5.7/typo3/sysext/core/Classes/PageTitle/PageTitleProviderManager.php
There must be a cleaner way to do this though, but I haven't found one yet.

I tried to implement a form with form framework in the news detail view. The basic way is explained here:
https://docs.typo3.org/c/typo3/cms-form/10.4/en-us/I/Concepts/FrontendRendering/Index.html#render-within-your-own-extbase-extension
Viewhelper:
<formvh:render persistenceIdentifier="EXT:myext/Resources/Private/Forms/myforms.form.yaml"/>
Form definition:
renderingOptions:
controllerAction: detailAction
addQueryString: true
submitButtonLabel: Absenden
fluidAdditionalAttributes:
class: ''
identifier: myForm
label: 'myLabel'
type: Form
prototypeName: myPrototype
The form is displayed. When I submit the form the news detail view is shown again including the form, but it's empty. The form is not processed. Something is missing, but I cannot find it in the manual.
Thanks!
I think the important part is written in the note below the linked paragraph:
In general, you can override each and every form definition with the help of TypoScript (see ‘TypoScript overrides’). This feature is not supported when you are rendering forms via the RenderViewHelper.
Luckily, there is a solution for your problem: use the ‘overrideConfiguration’ parameter instead. This way, you can override the form definition within your template. Provide an according array as shown in the example below.
<formvh:render persistenceIdentifier="EXT:my_site_package/Resources/Private/Forms/MyForm.yaml" overrideConfiguration="{renderables: {0: {renderables: {0: {label: 'My shiny new label'}}}}}"/>
That means you can check for post-variables by TypoScript conditions and adjust the controllerAction (and view) accordingly. The show / detail action is not processing the form usually, so it's logical that another action has to be assigned. I'm not sure in the moment if it does matter if double opt-in or a confirmation page shall be shown, that might depend on the form-extension.
After some hours of experimenting i was able to solve the problem. It ist simply a matter of caching ...
Georg has implemented in news a special caching engine which ignores the config.no_cache = 1 definition in setup. So the detail view of news is always cached even when the whole installation ist set to config.no_cache = 1. So this combination seems to work:
Viewhelper in Detail.html:
<formvh:render persistenceIdentifier="EXT:myext/Resources/Private/Forms/myforms.form.yaml"/>
And this definitions in the yaml file of the form:
renderingOptions:
controllerAction: detail
addQueryString: true
submitButtonLabel: Absenden
additionalParams:
no_cache: 1
identifier: myForm
label: 'myLabel'
type: Form
prototypeName: myPrototype
This renders the whole page without cache which is not optimal. It would be better when only the news entry is rendered without cache. and there is the problem, that in many installations the parameter 'disableNoCacheParameter' is set in the localconfiguration file which disallowes no_cache=1 in urls.
So i looked for an other - better - possibility to work around this problem.
First make a new fluid template anywhere in your resources folder with the modified viewhelper from above:
<formvh:render persistenceIdentifier="{settings.persistenceIdentifier}"/>
Then write a typoscript like this:
lib.embeddedForm = COA_INT
lib.embeddedForm {
10 = FLUIDTEMPLATE
10 {
file = EXT:myext/Resources/Private/Forms/myForm.html
settings {
EXT:myext/Resources/Private/Forms/myforms.form.yaml
}
extbase {
pluginName = Formframework
controllerExtensionName = Form
controllerName = FormFrontend
controllerActionName = perform
}
}
}
And final you can embed the form with
<f:cObject typoscriptObjectPath="lib.embeddedForm" />
as COA_INT in the news template. This disables the caching of the form.
Perhaps it helps ...
I'm using TYPO3 v8, how can I get the id of the current page that I'm editing in the backend?
You can get current PageId like this.
in Controller file.
$currentPid = $GLOBALS['TSFE']->id
Using Typoscript.
temp.page_uid = TEXT
temp.page_uid.field = uid
Example: In your controller:
$id = (int)\TYPO3\CMS\Core\Utility\GeneralUtility::_GP('id');
This depends on context, examples:
If you are extending FormEngine (editing records), the parent page record is in the data array, prepared by some rather early data provider.
If you are adding a feature to the 'info' module, the page id is a GET parameter, you should be able to access this in your controller.
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.
I don't really know how to word the title well, but here's my issue. I decided instead of having 25 controllers to handle pages, I have one PageController with a viewAction that takes in a :page parameter - for example, http://localhost/website/page/about-us would direct to PageController::viewAction() with a parameter of page = about-us. All of the pages are stored in a templates folder, so the viewrenderer is set to render application\templates\default\about-us.phtml.
I did this so I can consolidate and it seemed like a better approach. My question is the following: lets say when the page request is contact-us, I would need a Zend_Form to be used within the contact page. So, I would need a way within PageController::viewAction() to recognize that the page needs to have a form built, build the form, and also upon submission the need to process it (maybe this should be handled in an abstract process method - not sure).
I have no idea how to implement this. I thought maybe I can store a column with the name of a form and a connecting page identifier. Even better, create a one-to-many page to forms, and then in the submission loop through the forms and check if submitted and if so then process it (maybe there is a isSubmitted() method within zend_form. I really don't know how to handle this, and am looking for any help i can get.
Thanks!
Here is something that came to mind that may work or help point you in a direction that works for you.
This may only work well assuming you were to have no more than one form per page, if you need more than one form on a page, you would have to do something beyond this automatic form handling.
Create a standard location for forms that are attached to pages (e.g. application/forms/page). This is where the automatic forms associated with pages will be kept.
In your viewAction, you could take advantage of the autoloader to see if a form for that page exists. For example:
$page = $this->getParam('page');
$page = ucfirst(preg_replace('/-(\w)/ie', "strtoupper('$1')", $page)); // contact-us -> ContactUs
$class = 'Application_Form_Page_' . $page;
// class_exists will invoke the autoloader to map a class to a file
if (class_exists($class)) {
// a form is defined for this page
$form = new $class();
// check if form was posted
if ($this->getRequest()->isPost()) {
if ($form->isValid($this->getRequest()->getPost()) {
// form is valid - determine how to process it
}
}
// assign the form to the view
$this->view->pageForm = $form;
}
All this really leaves out is the action you take to process a specific form. Since the contact form will likely generate an email, and another form may insert data into a database, you will need some sort of callback system or perhaps another class that can be mapped automatically which contains the form processor code.
Anyway something along those lines is what came to mind first, I hope that helps give you some more ideas.
I am currently working on a project developed using Zend Framework, based on the structure of my web page design I have reached a point where I have to pass a small number of variables to my layout from each Controller/Action. These variables are:
<?php Zend_Layout::getMvcInstance()->assign('pageId', 'page1'); ?>
<?php Zend_Layout::getMvcInstance()->assign('headerType', '<header id="index">'); ?>
The reason for passing this information is firstly, I pass the page id as the multi column layout may change depending on the content being displayed, thus the page id within the body tag links the appropriate CSS to how the page should be displayed. Secondly I display a promotional jQuery slider only on the index page, but I need the flexibility to have it displayed on potentially multiple pages in case the wind changes and the client changes their mind.
My actual question: Is there a more appropriate method of passing this information to the Layout that I am overlooking?
I am not really questioning whether the information has to be sent, rather is there some Zend Framework feature that I have, in my haste, overlooked which would reduce the amount of repetitive redundant code which may very well be repeated in multiple Actions within the same controller?
You could turn that logic into an action helper than you can call from your controllers in a more direct way. You could also make a view helper to accomplish the same thing but view helpers usually generate data for the view rather than set properties.
// library/PageId.php
class Lib_PageId extends Zend_Controller_Action_Helper_Abstract
{
public function direct($title, $pageId, $headerType)
{
$view = $this->getActionController()->view;
$view->headTitle()->append($title);
$view->pageId = $pageId;
$view->headerType = $headerType;
}
}
In your controller actions you can now do this:
$this->_helper->PageId('Homepage', 'page1', 'index');
// now pageId and headerType are available in the view and
// Homepage has been appended to the title
You will also need to register the helper path in your Bootstrap like this:
protected function _initActionHelpers()
{
Zend_Controller_Action_HelperBroker::addPrefix('Lib');
}
Doing it like that can reduce the amount of repetitive code and remove needing to assign the values from the view. You can do it in the controller very quickly. You can also have default values in the case that the helper hasn't been called.
You shoudn't really be passing anything from the view to the layout, for a start the view should be included IN the layout, not the other way around.
So, setting your page title should be done using similar code to what you have, but inside the controller action being called:
$this->view->headTitle()->append('Homepage');
And the other two issues - you need to rethink as I stated to begin with. Maybe you're misunderstanding the layout/view principle? If you include the different views per action, then you simply change the div id when needed, and include the header for your banner only in the index.phtml file.
