在php中返回数组的空值

Question

我想从下拉列表中获取多个输入，但它返回一个没有值。附后是代码： 控制器： -

public function mark_error($id = null, $email=null) 
{ 
    if($this->userlib->isLoggedIn()) 
    { 
     if($this->userlib->isAdmin()) 
     { 
      $seller_error = $this->input->post('seller_error'); 
      if(is_null($seller_error)) 
      { 
       $seller_error = array(); 
      } 
      $marked_error_seller = implode(',', $seller_error); 

      $bank_error = $this->input->post('bank_error'); 
      if(is_null($bank_error)) 
      { 
       $bank_error = array(); 
      } 
      $marked_error_bank = implode(',', $bank_error); 

      $store_error = $this->input->post('store_error'); 
      if(is_null($store_error)) 
      { 
       $store_error = array(); 
      } 
      $marked_error_store = implode(',', $store_error); 

      $id2 = $this->userlib->getId(); 
      $data['admin_data'] = $this->admin_panel_model->admin_data($id2); 

      $data['marked_error_seller']=$marked_error_seller; 
      $data['marked_error_store']=$marked_error_store; 
      $data['marked_error_bank']=$marked_error_bank; 
      $data['email']=$email; 

      $this->admin_panel_model->mark_error_seller($id, $marked_error_seller); 
      $this->admin_panel_model->mark_error_bank($id, $marked_error_bank); 
      $this->admin_panel_model->mark_error_store($id, $marked_error_store);        
      $this->load->view('send_mail', $data); 
     } 
     else 
     { 
      echo "User not Allowed"; 
     } 
    } 
    else 
    { 
     echo "User not Logged In"; 
    } 
} 

模型： -

public function mark_error_seller($id, $marked_error_seller) 
{ 
    $data = array('marked_error_seller'=>$marked_error_seller, 'seller_status'=>2); 
    $this->db->update($this->seller_table, $data, array('id'=>$id)); 
    $status = array('error_status'=>1, 'admin_check'=>8); 
    $this->db->update($this->table, $status, array('id'=>$id)); 
} 

public function mark_error_bank($id, $marked_error_bank) 
{ 
    $data1 = array('marked_error_bank'=>$marked_error_bank, 'bank_status'=>2); 
    $this->db->update($this->bank_table, $data1, array('id'=>$id)); 
    $status = array('error_status'=>1, 'admin_check'=>8); 
    $this->db->update($this->table, $status, array('id'=>$id)); 
} 

public function mark_error_store($id, $marked_error_store) 
{ 
    $data2 = array('marked_error_store'=>$marked_error_store, 'store_status'=>2); 
    $this->db->update($this->store_table, $data2, array('id'=>$id)); 
    $status = array('error_status'=>1, 'admin_check'=>8); 
    $this->db->update($this->table, $status, array('id'=>$id)); 
} 

视图： -

<form action= "<?=site_url('admin_panel/mark_error/'.$id.'/'.$email)?>" method="post" enctype="multipart/form-data"> 
          <div class="box-body">

         </form> 

阐述，状态在数据库中，但成功更改来自三个下拉列表的输入没有被更新，请帮助。

试试这个

在控制器

public function mark_error($id = null, $email=null) 
{ 
    if($this->userlib->isLoggedIn()) 
    { 
     if($this->userlib->isAdmin()) 
     { 

      $seller  = $this->input->post('seller_error'); 
      $bank = $this->input->post('bank_error'); 
      $store = $this->input->post('store_error'); 

      if (empty($seller) || empty($bank) || empty($store)) { 
       echo "Field(s) is(are) Empty"; 
      } 
      else 
      { 
       $id2 = $this->userlib->getId(); 
       if (empty($id2)) { 
        echo "ID Field is empty"; 
       } 
       else 
       { 
        $this->admin_panel_model->mark_error_seller($id, $seller); 
        $this->admin_panel_model->mark_error_bank($id, $bank); 
        $this->admin_panel_model->mark_error_store($id, $store); 

        $data['admin_data'] = $this->admin_panel_model->admin_data($id2); 

        $this->load->view('send_mail', $data);     
       } 
      } 
     } 
     else 
     { 
      echo "User not Allowed"; 
     } 
    } 
    else 
    { 
     echo "User not Logged In"; 
    } 
} 

在型号

public function mark_error_seller($id, $seller) 
{ 
    $data = array(
     'marked_error_seller' => $seller, 
     'seller_status' => '2', 
     'error_status' => '1', 
     'admin_check' => '8' 
    ); 
    $this->db->where('id', $id); 
    $this->db->update('seller', $data); # I assume tabe name is seller 
} 

public function mark_error_bank($id, $bank) 
{ 
    $data = array(
     'marked_error_bank' => $bank, 
     'bank_status' => '2', 
     'error_status' => '1', 
     'admin_check' => '8' 
    ); 
    $this->db->where('id', $id); 
    $this->db->update('bank', $data); # I assume tabe name is bank 
} 

public function mark_error_store($id, $store) 
{ 
    $data = array(
     'marked_error_store' => $store, 
     'store_status' => '2', 
     'error_status' => '1', 
     'admin_check' => '8' 
    ); 
    $this->db->where('id', $id); 
    $this->db->update('store', $data); # I assume tabe name is store 
}
