TYPO3: Saving foreign mm table in new action - php

Question

I have two entities: Request and Event.
So when creating a Request in the Frontend, the user may select the Events (multiple checkboxes) which are affected by his request. Obviously, it's a MM-relation.
I managed to display every Event inside the FormFields.html partial of the Request. Following code is used:
RequestController.php (only the new action)
/**
* action new
*
* #param \Vendor\ExtName\Domain\Model\Request $newRequest
* #ignorevalidation $newRequest
* #return void
*/
public function newAction(\Vendor\ExtName\Domain\Model\Request $newRequest = NULL) {
$events = $this->eventRepository->findAll();
$this->view->assign('events', $events);
$this->view->assign('newRequest', $newRequest);
}
...passed all arguments inside the New.html into the FormField.html
<f:render partial="Request/FormFields" arguments="{_all}"/>
and have a checkbox rendered for each {events}
<f:for each="{events}" as="event">
<f:form.checkbox value="{event.uid}" name="events" id="event{event.uid}"/>
<label for="event{event.uid}">{event.namede}</label><br/>
</f:for>
TCA:
'events' => array(
'exclude' => 1,
'label' => 'LLL:EXT:extname/Resources/Private/Language/locallang_db.xlf:tx_extname_domain_model_request.events',
'config' => array(
'type' => 'select',
'foreign_table' => 'tx_extname_domain_model_event',
'MM' => 'tx_extname_request_event_mm',
'size' => 10,
'autoSizeMax' => 30,
'maxitems' => 9999,
'multiple' => 0,
'wizards' => array(
'_PADDING' => 1,
'_VERTICAL' => 1,
'edit' => array(
'type' => 'popup',
'title' => 'Edit',
'script' => 'wizard_edit.php',
'icon' => 'edit2.gif',
'popup_onlyOpenIfSelected' => 1,
'JSopenParams' => 'height=350,width=580,status=0,menubar=0,scrollbars=1',
),
'add' => Array(
'type' => 'script',
'title' => 'Create new',
'icon' => 'add.gif',
'params' => array(
'table' => 'tx_extname_domain_model_event',
'pid' => '###CURRENT_PID###',
'setValue' => 'prepend'
),
'script' => 'wizard_add.php',
),
),
),
),
But I have no idea how to save the values of the selected events into the DB. Can anyone help?

Answer 1

Instead name="events" use property="nameOfPropertyInYourModel"
<f:form.checkbox value="{event.uid}" name="events" id="event{event.uid}"/>
Lije this:
<f:form.checkbox value="{event.uid}" property="events" id="event{event.uid}"/>
And Extbase will figure out connection itself. I would suggest to use property instead name for all properties you want to store in model.
