TYPO3: Render a plugin via Typoscript or ViewHelper and change settings - typo3

Question

I would like to load a plugin dynamically according to some data. First I tried to do it with Typoscript, but after some research I figured out, that it is not possible to change the settings of the plugin (see old forum entry).
I need to change settings.simplepoll.uid according to the passed data:
This is the Typoscript I tried:
lib.loadSimplepoll = USER
lib.loadSimplepoll {
userFunc = TYPO3\CMS\Extbase\Core\Bootstrap->run
extensionName = Simplepoll
pluginName = Polllisting
vendorName = Pixelink
switchableControllerActions {
SimplePoll {
1 = list
}
}
settings < plugin.tx_simplepoll.settings
settings {
simplepoll {
uid.current = 1
}
}
}
The call in the template looks like that:
<f:cObject typoscriptObjectPath="lib.loadSimplepoll">{newsItem.simplepoll}</f:cObject>
After figuring out, that changing the settings is not possible, I tried a viewhelper:
<?php
namespace Vendor\Extension\ViewHelpers;
use TYPO3\CMS\Core\Utility\GeneralUtility;
class LoadSimplepollViewHelper extends \TYPO3\CMS\Fluid\Core\ViewHelper\AbstractViewHelper
{
/**
* #param int $uid Uid of poll
* #return string
*/
public function render($uid) {
$cObj = GeneralUtility::makeInstance('TYPO3\CMS\Frontend\ContentObject\ContentObjectRenderer');
$configurationManager = GeneralUtility::makeInstance('TYPO3\\CMS\\Extbase\\Configuration\\ConfigurationManager');
$simplepollTs = $configurationManager->getConfiguration(
\TYPO3\CMS\Extbase\Configuration\ConfigurationManagerInterface::CONFIGURATION_TYPE_SETTINGS,
'simplepoll',
'Polllisting'
);
$ttContentConfig = array(
'tables' => 'tt_content',
'source' => 1030,
'dontCheckPid' => 1
);
// returning this works perfectly!
// but I need to change the "settings.simplepoll.uid"
$data = $cObj->RECORDS($ttContentConfig);
$cObj->start($data, 'tx_simplepoll_domain_model_simplepoll');
$renderObjName = '<tt_content.list.20.simplepoll_polllisting';
$renderObjConf = $GLOBALS['TSFE']->tmpl->setup['tt_content.']['list.']['20.']['simplepoll_polllisting.'];
$renderObjConf['persistence']['storagePid'] = 394; // This does not work!
$renderObjConf['settings'] = $simplepollTs;
$renderObjConf['settings']['simplepoll']['uid'] = $uid;
return $cObj->cObjGetSingle($renderObjName, $renderObjConf);
}
}
The viehelper is called like this:
{vh:LoadSimplepoll(uid: '{newsItem.simplepoll}')}
Now I am able to change the uid of the poll with this line:
$renderObjConf['settings']['simplepoll']['uid'] = $uid;
My problem is now, that it loads the poll, but not the answers. I tracked this down to the fact, that the plugin somehow does not know the Record Storage Page anymore. The line $renderObjConf['persistence']['storagePid'] = 394; does not help.
How can I tell the plugin the Storage Pid?
Or is there another/better way to load a plugin with changing data?

Why shouldn't it be possible to modify settings.simplepoll.uid in typoscript?
because the extension simplepoll does not handle any stdWrap functionality to its typoscript settings.
Have a look into the code:
this special setting is used here:
$simplePoll = $this->simplePollRepository->findByUid($this->settings['simplepoll']['uid']);
no stdWrap, just plain usage.
compare it to ext:news:
before any settings is used it is processed. A dedicated join of typoscript settings with the settings in the plugin. And if necessary there is a stdWrap possible: here
$this->originalSettings = $originalSettings;
// Use stdWrap for given defined settings
if (isset($originalSettings['useStdWrap']) && !empty($originalSettings['useStdWrap'])) {
$typoScriptService = GeneralUtility::makeInstance(TypoScriptService::class);
$typoScriptArray = $typoScriptService->convertPlainArrayToTypoScriptArray($originalSettings);
$stdWrapProperties = GeneralUtility::trimExplode(',', $originalSettings['useStdWrap'], true);
foreach ($stdWrapProperties as $key) {
if (is_array($typoScriptArray[$key . '.'])) {
$originalSettings[$key] = $this->configurationManager->getContentObject()->stdWrap(
$typoScriptArray[$key],
$typoScriptArray[$key . '.']
);
}
}
}
As you can see:
extbase does not support you with typoscript stdWrap functionality.
You (and every extension author) need to do it by hand. But that was so even before extbase.
In this way: as you can not configure your value you only can trick TYPO3 (and the plugin):
if you have a small number of uids you can have one variant for each uid
lib.loadSimplepoll123 < lib.loadSimplepoll
lib.loadSimplepoll123.settings.simplepoll.uid = 123
lib.loadSimplepoll234 < lib.loadSimplepoll
lib.loadSimplepoll234.settings.simplepoll.uid = 234
lib.loadSimplepoll345 < lib.loadSimplepoll
lib.loadSimplepoll345.settings.simplepoll.uid = 345
lib.loadSimplepoll456 < lib.loadSimplepoll
lib.loadSimplepoll456.settings.simplepoll.uid = 456
and call it like
<f:cObject typoscriptObjectPath="lib.loadSimplepoll{newsItem.simplepoll}" />
or you build a pull request implementing the stdWrap functionality and send it to the extension author.

Why shouldn't it be possible to modify settings.simplepoll.uid in typoscript?
you just need the correct construction to modify it.
For a single value you can use current, but use it properly. It is a stdWrap function which needs to be evaluated.
If there is no stdWrap evaluation by default it might work with a cObject of type TEXT
settings.simplepoll.uid.cObject = TEXT
settings.simplepoll.uid.cObject.current = 1
or to indicate a stdWrap you need to use stdWrap literally:
settings.simplepoll.uid.stdWrap.current = 1
another variant of data transfer are named parameters. Just build an associative array as data parameter and access the values individual:
fluid:
<f:cObject typoscriptObjectPath="lib.arraytest" data="{a:'abc',b:'xyz'}" >
inside text
</f:cObject>
and the typoscript:
lib.arraytest = COA
lib.arraytest {
10 = TEXT
10.field = a
10.wrap = /|/
20 = TEXT
20.field = b
20.wrap = \|\
}
which results in an output of /abc/\xyz\. Be aware: the inner text of the f:cobject tag will be lost as the data parameter has priority about inner children.

In the meantime I got the Viewhelpter to work:
Viewhelper:
<?php
namespace Vendor\Extension\ViewHelpers;
use TYPO3\CMS\Core\Utility\GeneralUtility;
class LoadSimplepollViewHelper extends \TYPO3\CMS\Fluid\Core\ViewHelper\AbstractViewHelper
{
/**
* #return void
*/
public function initializeArguments()
{
parent::initializeArguments();
$this->registerArgument('simplepollUid', 'int', 'Uid of simplepoll', false);
}
/**
* #return string
*/
public function render()
{
$configurationManager = GeneralUtility::makeInstance('TYPO3\\CMS\\Extbase\\Configuration\\ConfigurationManager');
$simplepollTs = $configurationManager->getConfiguration(
\TYPO3\CMS\Extbase\Configuration\ConfigurationManagerInterface::CONFIGURATION_TYPE_SETTINGS,
'simplepoll',
'Polllisting');
$cObj = GeneralUtility::makeInstance('TYPO3\CMS\Frontend\ContentObject\ContentObjectRenderer');
$renderObjName = '<tt_content.list.20.simplepoll_polllisting';
$renderObjConf = $GLOBALS['TSFE']->tmpl->setup['tt_content.']['list.']['20.']['simplepoll_polllisting.'];
$renderObjConf['settings'] = $simplepollTs;
$renderObjConf['settings']['simplepoll']['uid'] = (int)$this->arguments['simplepollUid'];
return $cObj->cObjGetSingle($renderObjName, $renderObjConf);
}
}
Call the viewhelper in the template (don't forget to register the namespace):
{vh:LoadSimplepoll(simplepollUid: '{newsItem.ipgSimplepoll}')}
That's it.
