I have created a view helper in TPYO3 11.
<?php
namespace DN\RisaProjects\Viewhelpers;
use TYPO3Fluid\Fluid\Core\Rendering\RenderingContextInterface;
use TYPO3Fluid\Fluid\Core\ViewHelper\AbstractViewHelper;
use TYPO3Fluid\Fluid\Core\ViewHelper\Traits\CompileWithRenderStatic;
class TestViewHelper extends AbstractViewHelper
{
use CompileWithRenderStatic;
protected $escapeOutput = false;
public function initializeArguments()
{
// registerArgument($name, $type, $description, $required, $defaultValue, $escape)
$this->registerArgument('test', 'string', 'test', true);
}
public static function renderStatic(
array $arguments,
\Closure $renderChildrenClosure,
RenderingContextInterface $renderingContext
)
{
return $arguments['test'];
}
}
The namespace is registered in ext_localconf.php
$GLOBALS['TYPO3_CONF_VARS']['SYS']['fluid']['namespaces']['rp'] = [
'DN\RisaProjects\ViewHelpers',
];
In the Fluid template I use it like this
<rp:test test="hallo" />
As far as how I have always done it so far. The first call also works. But when the page is loaded from the cache, the viewhelper class is no longer found.
Fluidcache File:
$output0 .= DN\RisaProjects\Viewhelpers\TestViewHelper::renderStatic($arguments36, $renderChildrenClosure37, $renderingContext);
Class "DN\RisaProjects\Viewhelpers\TestViewHelper" not found
What could be the reason for that? I have checked the syntax several times and the autoload files are also correct. The first call also works.

In order to use the "Klaro! Consent Manager" I need to modify the iframe-tag a little bit, which is automatically generated by TYPO3 when you embed a YouTube video with a textmedia element.
It is generated in /typo3/sysext/core/Classes/Resource/Rendering/YouTubeRenderer.php
public function render(FileInterface $file, $width, $height, array $options = [], $usedPathsRelativeToCurrentScript = false)
{
$options = $this->collectOptions($options, $file);
$src = $this->createYouTubeUrl($options, $file);
$attributes = $this->collectIframeAttributes($width, $height, $options);
return sprintf(
'<iframe src="%s"%s></iframe>',
htmlspecialchars($src, ENT_QUOTES | ENT_HTML5),
empty($attributes) ? '' : ' ' . $this->implodeAttributes($attributes)
);
}
I already have a user_site extension to configure the system and edit the templates, but without any php classes. It looks like I can't just overwrite a fluid template here. I'm an integrator, not an extension developer, and i wonder how i can overwrite or extend this function accordingly, without changing or duplicating too much of the core functions.
How can I replace <iframe src= with <iframe data-name="youtube" data-src=?
Thanks to the comment from nstungcom I have found good samples in the extension media2click and was able to modify the iFrame tag with fragments of this. Since I am not an extension developer, this solution should be used with caution until it is confirmed by a developer. Suggestions for improvement are very appreciated.
I made the following changes / additions to my sitepackage ("user_site" extension):
/ext/user_site/Classes/Resource/Rendering/YouTubeRenderer.php
<?php
namespace MyVendorName\UserSite\Resource\Rendering;
use TYPO3\CMS\Core\Core\Environment;
use TYPO3\CMS\Core\Resource\FileInterface;
use TYPO3\CMS\Core\Resource\FileReference;
use TYPO3\CMS\Core\Utility\GeneralUtility;
use TYPO3\CMS\Frontend\ContentObject\ContentObjectRenderer;
class YouTubeRenderer extends \TYPO3\CMS\Core\Resource\Rendering\YouTubeRenderer
{
public function getPriority()
{
return 25;
}
public function render(FileInterface $file, $width, $height, array $options = [], $usedPathsRelativeToCurrentScript = false)
{
$options = $this->collectOptions($options, $file);
$iframe = str_replace(' src="', ' src="" data-name="youtube" data-src="', parent::render($file, $width, $height, $options, $usedPathsRelativeToCurrentScript));
return $iframe;
}
}
I'm uncertain if all of those use statements and the getPriority function are really necessary.
/ext/user_site/ext_localconf.php
<?php
defined('TYPO3_MODE') or die();
call_user_func(function () {
$rendererRegistry = \TYPO3\CMS\Core\Resource\Rendering\RendererRegistry::getInstance();
$rendererRegistry->registerRendererClass(\MyVendorName\UserSite\Resource\Rendering\YouTubeRenderer::class);
});
I do not know if this is a so-called XCLASS. The syntax looks different from what I found as an example in the Api.
/ext/user_site/ext_emconf.php
<?php
$EM_CONF[$_EXTKEY] = [
'title' => 'Project specific configuration and templates',
// [...]
'autoload' => [
'psr-4' => [
'MyVendorName\\UserSite\\' => 'Classes',
],
],
];
Apparently it needed this autoload, whatever that's for.
In indexAction() method of IndexController I have called the method of model which returns the list of employees(employeeList) from database.And then add this this employeeList to $view and then call $view->render('index.phtml') and index .phtml shows the employeeList.The code is ad follows:
IndexController.php
<?php
require_once('../Zend/Controller/Action.php');
require_once('../models/HRModel.php');
require_once('../Zend/View.php');
class IndexController extends Zend_Controller_Action
{
protected $hrModel;
public function init()
{
$this->hrModel = new Application_Model_HRModel();
}
public function indexAction()
{
$view = new Zend_View(array('scriptPath' =>'../views'));
$view->employeeList = $this->hrModel->queryAllEmployees();
echo $view->render('index.phtml');
}
}
Application_model_HRModel.php
<?php
require_once('Zend/Db.php');
require_once('Zend/Config/Ini.php');
class Application_Model_HRModel
{
protected $db=null;
public function queryAllEmployees() {
return $this->db->fetchAssoc("select comment from guestbook");
}
}
index.phtml
foreach ($this->employeeList as $emp):
extract($emp);
echo '$EMPLOYEE_ID';
echo $comment;
endforeach
Now I want to start the execution from indexAction() method.But how to do this?What should be the url to be entered in browser?In request parameter the controller will be IndexController and action will be indexAction.So Kindly help me in resolving this issue.
To execute this action, you need to call the Index Controller with index Action. So you use www.foo.bar/index/index or simple www.foo.bar.
If this dont work, you have maybe a error in your confoguration.
Or did i mistake your question?
How did you configure your PHP Error handling? Maybe you have a PHP error that is not displayed.
I'm trying to build a query string as following:
Next Page
I want to add an array to query string. For example, array('find_loc'=>'New+York', 'find_name'=>'starbucks')
I expect to get url that looks like http://example.com/1/?find_loc=New+York&find_name=starbucks
What's the best way to do this? I found a similar question that suggested appending the string to the url. Is there a helper for query string?
Simple answer to your question is no.
Here is the class description:
/**
* Helper for making easy links and getting urls that depend on the routes and router
*
* #package Zend_View
* #subpackage Helper
* #copyright Copyright (c) 2005-2011 Zend Technologies USA Inc. (http://www.zend.com)
* #license http://framework.zend.com/license/new-bsd New BSD License
*/
Helper for making easy links and getting urls that depend on the routes and router
I think the description is clear in it's purpose. Use it for making URLs that depend on the routes and router. So, just append your query strings as recommend in the link you posted in your question.
The following should work for you:
Next Page
The ZF-Router will map the values to the Request object.
In your controller you can access these params with the Response-Object:
$loc = $this->getRequest()->getParam('find_loc');
$name = $this->getRequest()->getParam('find_name);
You can make custom helper:
class My_View_Helper_UrlHttpQuery extends Zend_View_Helper_Abstract
{
public function urlHttpQuery($query)
{
$urlHelper = $this->view->getHelper('url');
$params = func_get_args();
array_shift($params);//removing first argument
$url = call_user_func_array(($urlHelper, 'url'), $params);
if(!is_string($query)) { //allow raw query string
$query = array($query);
$query = http_build_query($query);
}
if(!empty($query) {
$url .= '?' . ltrim('?', $query);
}
return $url;
}
}
After you register this helper with view, you can use it like this Next Page
Working code
/**
* Class Wp_View_Helper_UrlHttpQuery
*/
class Wp_View_Helper_UrlHttpQuery extends Zend_View_Helper_Abstract
{
public function urlHttpQuery($query = array())
{
$urlHelper = $this->view->getHelper('url');
$params = func_get_args();
//removing first argument
array_shift($params);
$url = call_user_func_array(array($urlHelper, 'url'), $params);
if (is_array($query) || is_object($query)) {
$query = http_build_query($query);
}
if (!empty($query)) {
$url .= '?' . ltrim($query, '?');
}
return $url;
}
}
since the upstream code doesn't work
i have a got a helpers folder in my views folder with a helper called Log.php
/views/helpers/log.php
which contains:
class Zend_View_Helper_Log extends Zend_View_Helper_Abstract
{
public function loggedAs ()
{
$auth = Zend_Auth::getInstance();
if ($auth->hasIdentity()) {
$username = $auth->getIdentity()->uname;
$logoutUrl = $this->view->url(array('controller'=>'auth', 'action'=>'logout'), null, true);
return 'Hello' . $username . '. Logout?';
}
}
}
how can i call this from layouts? or views? i tried $this->_helpers->log->loggedAs();
but doesnt display anything, just an error:Fatal error: Call to a member function loggedAs() on a non-object in ...
I have a little experience in ZF. Yesterday I have the same problem and I decided its with the following code.
In the main Bootstrap.php I defined helper Path and Prefix
protected function _initDoctype()
{
$this->bootstrap('view');
$view = $this->getResource('view');
$view->doctype('XHTML1_STRICT');
$view->addHelperPath(APPLICATION_PATH . "/../library/My/Helper/View", "My_Helper_View");
}
After that in view file I used next syntax
$this->getPhoneString($value['per_telephone_number']);
where getPhoneString method in my Helper Class My_Helper_View_GetPhoneString
Hope this example will be useful for you :)
Your helper class should have a method that matches the name of the helper, and this is what you call. So if you want to call loggedAs() from your templates then this is what you should name your helper:
class Zend_View_Helper_LoggedAs extends Zend_View_Helper_Abstract
{
public function loggedAs()
{
$auth = Zend_Auth::getInstance();
if ($auth->hasIdentity()) {
$username = $auth->getIdentity()->uname;
$logoutUrl = $this->view->url(array('controller'=>'auth', 'action'=>'logout'), null, true);
return 'Hello' . $username . '. Logout?';
}
}
}
this should then live in a file at application/views/helpers/LoggedAs.php, and you'd call it from within your templates like this:
<?=$this->loggedAs()?>
I'd also recommend using your own namespace instead of Zend in the class name, but the way you've done it should work as well.
i need advice on how i can implement this action helper. currently, i have something like
class Application_Controller_Action_Helper_AppendParamsToUrl extends Zend_Controller_Action_Helper_Abstract {
function appendParamsToUrl($params = array()) {
$router = Zend_Controller_Front::getInstance()->getRouter();
$url = $router->assemble($params);
if (!empty($_SERVER['QUERY_STRING'])) {
$url .= $_SERVER['QUERY_STRING'];
}
return $url;
}
}
but as you can see, i think the function should be a static function? but how will that find into this Zend_Controller_Action_Helper thingy?
Make the function public and in your BootStrap.php ensure the controller helper can be autoloaded
// add paths to controller helpers
Zend_Controller_Action_HelperBroker::addPath( APPLICATION_PATH .'/controllers/helpers');
You should then be able to call the helper from your controller via
$this->_helper->appendParamsToUrl->appendParamsToUrl();
You can also rename appendParamsToUrl() function to direct()
function direct( $params = array() ) {...}
In this case, you'll be able to access it from controller with
$this->_helper->appendParamsToUrl( $params );
