Question

如果我有一个输入字段，其中包含有关'customer_id'的多个选项，则生成的数据请求为

$ request-＆gt;包含数组的数据（CompanysCustomer =＆gt; array（'id'=＆gt;'1'，'uid'=＆gt;'fhs32hrqwr8wfsdiof'，'customer_id'=＆gt;数组（'0'= ＆gt;'5'，'1'=＆gt;'8'，'2'=＆gt;'9'））。

我不知道如何使用或使用这个数组。当我不使用多个时，它运行良好，因为那时我没有在'customer_id'获得数组。我有一个想法来操纵数组并将它们列出来执行save pr foreach，但这看起来效率不高，它必须是其他方式吗？

我无法将此保存到数据库。当我有一个单独的记录保存时，我设法做到了。我不能一次保存很多记录。

版本2.4.1

public function add($id) {
  if ($this->request->is('post')) {
    $this->CompanysCustomer->create();
    if ($this->CompanysCustomer->save($this->request->data)){
      $this->Session->setFlash(__('The Companys Customer has been saved.'));
      return $this->redirect(array('action' => 'index'));
    }
  else{
    $this->Session->setFlash(__('The Companys Customer could not be saved. Please, try    again.'));}
  }

  $customers = $this->CompanysCustomer->Customer->find('list');
  $this->set(compact('customers'));
  }

Model CompanysCustomer

  <?php
  App::uses('AppModel', 'Model');
  /**
  * CompanysCustomer Model

  */
  class CompanysCustomer extends AppModel {
    //The Associations below have been created with all possible keys, those that are not needed can be removed

    /**
    * belongsTo associations
    *
    * @var array
    */
    public $belongsTo = array(
        'Company' => array(
            'className' => 'Company',
            'foreignKey' => 'company_id',
            'conditions' => '',
            'fields' => '',
            'order' => ''
        ),
        'Customer' => array(
            'className' => 'Customer',
            'foreignKey' => 'customer_id',
            'conditions' => '',
            'fields' => '',
            'order' => ''
        )
    );
}

查看：CompanyCustomer \ add.ctp

<div class="companysCustomers form">
    <?php echo $this->Form->create('CompanysCustomer'); ?>
    <fieldset>
        <legend><?php echo __('Add Companys Customer'); ?></legend>
        <?php
        $company_id = $id;
        echo $this->Form->input('company_id', array(
            'type' => 'hidden',
            'value' => $id,
        ));
        $uid = uniqid("", $more_entropy = true);
        echo $this->Form->input('uid', array(
            'type' => 'hidden',
            'value' => $uid,
        ));
        //echo $this->Form->input('company_id');
        echo $this->Form->input('customer_id',array('type' => 'select', 'multiple' => 'checkbox','size' => '20'));

        ?>
    </fieldset>
    <?php echo $this->Form->end(__('Submit')); ?>
</div>
