TYPO3: name of submit button in extbase - typo3

Question

I have a form with submit buttons save, save and close, save and view, and save and add, as usual in TYPO3. Each button is a <input type='image'> item, and the only difference is the name argument of the input. In my controller, how can I determine which submit button was clicked, in order to redirect to the right action?

Answer 1

You should not redirect to actions from the controller. It's better to call the correct action when a certain button is clicked. To keep the logic clear, you could use the f:link.action viewhelper for instance. Here is a good documentation about the viewhelpers: ViewHelper Reference. You can set an action and a controller attribute to this viewhelper. So no need to decide which button was clicked in the controller. To keep and pass your form data you should use the f:form ViewHelpers and write the form data onto an object.

Answer 2

The first problem I had was the name of the <input> that wasn't right. In order to get the right name, I have to build the tag using a ViewHelper derived from AbstractFormFieldViewHelper.
Now that the <input> tag is rendered the right way, I can see the name of the clicked <input> into $this->request->arguments.
For completeness, here is the code of the ViewHelper I used:
class IconSubmitViewHelper extends \TYPO3\CMS\Fluid\ViewHelpers\Form\AbstractFormFieldViewHelper {
/**
* #var string
*/
protected $tagName = 'input';
/**
* Initialize the arguments.
*
* #return void
* #api
*/
public function initializeArguments() {
parent::initializeArguments();
$this->registerArgument('icon', 'string', 'Icon name', true, 'actions-document-close');
$this->registerTagAttribute('src', 'string', 'Image source', false, 'clear.gif');
$this->registerUniversalTagAttributes();
}
/**
* Renders an icon link as known from the TYPO3 backend
*
* #return string the rendered icon link
*/
public function render() {
$name = $this->getName();
$this->registerFieldNameForFormTokenGeneration($name);
$this->tag->addAttribute('type', 'image');
$this->tag->addAttribute('name', $name);
$this->tag->addAttribute('class', 'c-inputButton');
return \TYPO3\CMS\Backend\Utility\IconUtility::getSpriteIcon($this->arguments['icon'], array('title' => $this->arguments['title'], 'html' => $this->tag->render()));
}
}
And here is the code in the Controller that redirect to the right page:
private function submitRedirect($myobject) {
if ($this->request->hasArgument('_savedok')) {
$this->redirect('edit', NULL, NULL, array('myobject'=>$myobject));
}
if ($this->request->hasArgument('_savedokclose')) {
$this->redirect('list');
}
if ($this->request->hasArgument('_savedoknew')) {
$this->redirect('new');
}
}
