cakephp检查删除后的数字

Question

我想检查市场的数量，如果是真的数量然后删除并重定向索引，否则重定向错误

控制器中的

：

public function admin_verif_num() {

        $this->set('title_for_layout', __('verification'));
        $this->Market->recursive = 2;

        $markets = $this->Market->find('list', array(
        'fields' => array('Market.num_mark')
        ));
        if (!empty($this->request->data)) {
        $num= $this->request->data['Market']['num_mark'];
        foreach ($markets as $nums) {
            if ($nums == $num) {
                $id= $this->request->id;
          $this->Session->setFlash(__('good'), 'default', array('class' => 'success'));

         $this->redirect(array('action' => 'delete',$id,true), null, __('Are you sure?'));
             } else{
         $this->Session->setFlash(__('error'), 'default', array('class' => 'success'));
          $this->redirect(array('action' => 'admin_verif_delete_num'));

             }   
        }
       }       
      $this->set('markets', $markets);
   }

在视图中：

<?php
                echo $this->Form->label('num_mark', '  : طلب الع'); ?>

                 <?php echo $this->Form->input('num_mark',array('label' => false )); 

                 ?>

结果为http://localhost/bib/admin/markets/delete/1 但不删除什么是真正的代码？
