I'm a new user of typo3 and I made a plugin to display users with a searchbar to filter them, but I have this error when I want to display my page :

(1/1) #1476107295 TYPO3\CMS\Core\Error\Exception
PHP Warning: Undefined array key "word" in MyPath/Controller/UserlistController.php line 44

In my controller, I try to get arguments to use it in my filter like this :

   public function listAction(int $currentPage = 1)
{
   $arguments = $this->request->getArguments();
   $users = $this->userlistRepository->findBySearch($arguments['word'] ? $arguments['word'] : '');

somecode ...

}

I tried a dump of $arguments, but it's empty

there is a part of my repository :

/**
     * @param string $word
     * @return object[]|\TYPO3\CMS\Extbase\Persistence\QueryResultInterface
     * @throws \TYPO3\CMS\Extbase\Persistence\Exception\InvalidQueryException
     */
    public function findBySearch(string $word) {
        $query = $this->persistenceManager->createQueryForType(\TYPO3\CMS\Extbase\Domain\Model\FrontendUser::class);
        $querySettings = $query->getQuerySettings();
        $querySettings->setStoragePageIds([26]);
        $query->setQuerySettings($querySettings);

        $query->setOrderings([
            'lastName' => QueryInterface::ORDER_ASCENDING
        ]);

Someone know why I can't get arguments ? thanks

If you need more part of code, please tell me

CodePudding user response：

If you just call the List action without sending the filter form the arguments are empty.

You should test each expected argument before accessing it like this:

if($this->request->hasArgument('word')) {
        $searchOption = $this->request->getArgument('word'));
}

CodePudding user response：

You could try using the null coalescencing operator here:

$users = $this->userlistRepository->findBySearch($arguments['word'] ?? '');

If that doesn't do the trick, you check if the value is set before (see the answer of Tobias Gaertner). Also keep in mind that

$this->request->getArguments();

only gets the arguments in your current plugin context, so any parameters looking like tx_yourplugin_p1[argument]. You have to make sure you properly pass this parameter. If you have to use the general GET parameters, you can use

\TYPO3\CMS\Core\Utility\GeneralUtility::_GET();

CodePudding user response：

While the handling of the 'word' variable is one issue, I consider that if no search word is sent, perhaps another Repository-Method should be called. Below I entered $this->userlistRepository->findAll() but it could also show something else, perhaps just a template that states that a choice is required.

public function listAction(int $currentPage = 1)
{
   $arguments = $this->request->getArguments();
   if($this->request->hasArgument('word')) {
       $searchOption = $this->request->getArgument('word');
       $users = $this->userlistRepository->findBySearch($searchOption);
   }
   else {
      $users = $this->userlistRepository->findAll();
      somecode ...
   }
}
