Re: Update div with Selectbox

Hi all,
i have solved my problem by myself, but I am now once again facing another problem-where you can possibly help me.

First of all, my code

EventsController.php
public function edit($id = null) {
    $this->Event->id = $id;
    if (!$this->Event->exists()) {
        throw new NotFoundException('Ungültige Veranstaltung','error');
    }
    if ($this->request->is('post') || $this->request->is('put')) {
        if ($this->Event->save($this->request->data)) {
            $this->Session->setFlash('Die Veranstaltung wurde geändert !', 'success');
            $this->redirect(array('action' => 'index'));
        } else {
            $this->Session->setFlash('Die Veranstaltung konnte nicht geändert werden','error');
        }
    } else {
        $this->request->data = $this->Event->read(null, $id);
    }
    
    $variables = $this->Event->User->find('all', array('conditions'=>array('User.typ'=> array('einsatzleiter', 'fahrdienstleiter'))));
    $this->set(compact('variables'));

    $ansprechpartner = $this->Event->Passanger->find('all', array('conditions'=>array('Passanger.ansprechpartner'=> array('ja'))));
    $this->set(compact('ansprechpartner'));

    $events = $this->Event->find('all');
    $this->set('events', $events);
    $this->set('locations', $this->Event->Location->find('list'));
    
    $places = $this->Event->Place->find('all');
    $this->set(compact('places'));
}

public function data_interface($place_id) {
    $locations = $this->Event->Location->findAllByPlaceId($place_id);
    $this->set('locations', $locations);
}

public function save_data() {
    if(!empty($this->data)) {
        $this->Event->create($this->data);
        if($this->Event->saveAll()) {
            $this->Session->setFlash('Die Veranstaltung wurde geändert !', 'success');
            $this->redirect(array('action' => 'index'));
        } else {
            $this->Session->setFlash('Die Veranstaltung konnte nicht gespeichert !','error');
        }
        $this->autoRender = false;
    }
}

edit.ctp
<?php echo $this->Form->create('Event', array('type' => 'file',array('controller'=>'events', 'action' => 'save_data')));?>
<?php echo $this->Form->input('id'); ?>
.....
<tr>
    <th scope="row">Veranstaltungsort</th>
    <td>
        <?php
            $select_value = array();
            $select_value[null] = '-- Keine Auswahl --';
            foreach($places as $place) {
                $key     = $place['Place']['id'];
                $value   = $place['Place']['stadt'];
                $select_value[$key]    = $value;
            }
            $mydata = $this->data;
            if (  $mydata['Event']['place_id'] != null ) {
                foreach ( $select_value as $k => $v ) {
                    if ( $mydata['Event']['place_id'] == $k ) {
                        $this_is_selected =  $k;
                    }
                }
            } else {
                $this_is_selected = 0;    
            }
            echo $this->Js->Form->select('place_id', $select_value);
            echo $this->Js->writeBuffer();
        ?>    
    </td>
</tr>

<tr>
    <th scope="row">Locations</th>
    <td>
         <?php
            echo $this->Html->div(null, '', array('id' => 'target-div'));
        ?>
    </td>
</tr>
.....
<?php
    echo $this->Js->submit('Speichern', array(
        'url' => array(
            'controller' => 'events',
            'action' => 'save_data'
        )));
    echo $this->Js->writeBuffer();
    echo $this->Form->end();
?>

data_interface.ctp
<?php
    $select_value = array();        
        foreach($locations as $location) {
            $key    = $location['Location']['id'];
            $value    = $location['Location']['name'];
            $select_value[$key]    = $value;
        }
    echo $this->Form->select('location_id', $select_value, array('label'=> false, 'multiple' => 'checkbox'));
?>


The problem before I stand now is that I like to put the values ​​that are given to me as checkboxes from my ajax request also would like to save to the events controller. Unfortunately, this does not work and cake saves me no matter which checkbox i set, the value "1" to the database
.
Any ideas how I can solve this problem now?

Looking forward to help.
