How is the frequency variable written to the database?

Question

CakePHP

Good afternoon!
Help me understand how the variable "frequency" gets into the database. The site is written in CakePHP

Here is the editing template:

<div class="content-up">
  <span class="content-up__heading">Редактирование материала</span>
</div>
<div class="add-part">
  <?php 
    echo $this->Form->create('Imap', array('type' => 'file'));
  ?>
  <div class="edit_bot">

    <div class="bot_r">
    <?php
    echo $this->Form->input('region_id', array('label' => 'Область:', 'class' => 'region_list'));?>
<select id="districts" name="data[Imap][district_id]">
    <option value="0">Выберите район</option>
  <?php foreach($districts as $key => $value): ?>
    <option value="<?=$key?>" <?=($key == $data['Imap']['district_id']) ? 'selected' : ''?>><?=$value?></option>
  <?php endforeach ?>
</select>
<select class="towns" name="data[Imap][town_id]">
<option value="0">Выберите населенный пункт</option>
  <?php foreach($towns as $key => $value): ?>
    <option value="<?=$key?>" <?=($key == $data['Imap']['town_id']) ? 'selected' : ''?>><?=$value?></option>
  <?php endforeach ?>
</select>
<?php
echo $this->Form->input('title', array('label' => 'Наименование:'));
echo $this->Form->input('dates', array('label' => 'Дата ввода:'));
echo $this->Form->input('frequency', array('label' => 'Частота сигнала:'));
echo $this->Form->input('latitude', array('label' => 'Широта:'));
echo $this->Form->input('longitude', array('label' => 'Долгота:'));
echo $this->Form->input('diameter', array('label' => 'Диаметр:'));
    echo $this->Form->end('Редактировать');
    ?>
    </div>
  </div>
  <script type="text/javascript">
     //CKEDITOR.replace( 'editor' );
  </script>
</div>

And here is the controller that is responsible for this template

<?php

class ImapsController extends AppController{
  public function beforeFilter(){
    parent::beforeFilter();
  }
  // public $uses = array('Imap', 'Region');


  public function admin_index(){
    $data = $this->Imap->find('all');
    $this->set(compact('data'));
  }

  public function admin_add(){
    if($this->request->is('post')){
      $this->Imap->create();
      $data = $this->request->data['Imap'];
      if($this->Imap->save($data)){
        $this->Session->setFlash('Сохранено', 'default', array(), 'good');
        return $this->redirect($this->referer());
      }else{
        $this->Session->setFlash('Ошибка', 'default', array(), 'bad');
      }
    }
    $this->Imap->Region->locale = 'ru';
    $regions = $this->Imap->Region->find('list');
    $this->set(compact('title_for_layout', 'regions'));
  }

  public function admin_edit($id){

    if(is_null($id) || !(int)$id || !$this->Imap->exists($id)){
      throw new NotFoundException('Такой страницы нет...');
    }

    $data = $this->Imap->findById($id);

    if(!$id){
      throw new NotFoundException('Такой страницы нет...');
    }
    if($this->request->is(array('post', 'put'))){
      $this->Imap->id = $id;
      $data1 = $this->request->data['Imap'];
      $data1['id'] = $id;
      if($this->Imap->save($data1)){
        $this->Session->setFlash('Сохранено', 'default', array(), 'good');
        return $this->redirect($this->referer());
      }else{
        $this->Session->setFlash('Ошибка', 'default', array(), 'bad');
      }
    }
    //Заполняем данные в форме
    if($this->request->is('post')){
      $this->request->data = $data1;
      $data = $data1;
    }else{
      $data = $this->request->data = $this->Imap->read(null, $id);
    }
    $this->Imap->Region->locale = 'ru';
    $this->Imap->District->locale = 'ru';
    $this->Imap->Town->locale = 'ru';
    $regions = $this->Imap->Region->find('list');
    $districts = $this->Imap->District->find('list');
    $towns = $this->Imap->Town->find('list');
    $this->set(compact('id', 'data', 'regions','districts', 'dates', 'towns'));
  }

  public function admin_delete($id){
    if (!$this->Imap->exists($id)) {
      throw new NotFounddException('Такой статьи нет');
    }
    if($this->Imap->delete($id)){
      $this->Session->setFlash('Удалено', 'default', array(), 'good');
    }else{
      $this->Session->setFlash('Ошибка', 'default', array(), 'bad');
    }
    return $this->redirect($this->referer());
  }

}

The model also does not have this variable, but when editing in the database, its value is recorded. Do not tell me where to dig?

Answer 1

$this->Form->create('Imap', array('type' => 'file'));
//...
$data = $this->request->data['Imap'];

accordingly, $data will contain data from all form fields
