Question

有人可以帮我解决CodeIgniter中的条件字段验证吗？

尝试收集一些客户数据，如果用户在邮件单选按钮中选择“是”，则某些字段（如地址，城市，邮政编码等）将成为必填字段。

我在config / form_Validation.php中有CodeIgniter表单验证码，如下所示：

$config = array ( 'customer/new_customer' => array 
(
   array ( 'field' => 'firstName', 'label' => 'First Name', 'rules' => 'required' ),
   array ( 'field' => 'lastName', 'label' => 'Last Name', 'rules' => 'required'),
   array ('field' => 'mail', 'label' => 'Mail', 'rules' => 'required' ),
   array ('field' => 'address', 'label' => 'Address','rules' => ''),
   //other fields here
)

）;

我在控制器中有以下代码来添加/编辑客户：

function new_customer()
{
$customer_id = $this->input->post('customer_id');
if ($this->form_validation->run() == FALSE)
{
  if(($customer_id != "X") && ($customer_id != "")){
    $data['add_or_edit'] = "add";
    return $this->edit_customer($customer_id, 'add');
  }else {
    $data['title'] = "New Customer";
    $data['add_or_edit'] = 'add';
    $this->load->view('customer_form_view',$data);
  }

}else{
   $data['firstName'] = $this->input->post('firstName');
   $data['lastName'] = $this->input->post('lastName');
   if($this->input->post('mail') == "Yes")
   {
     $data['address'] = $this->input->post('address');
     $data['city'] = $this->input->post('city');
      //other fields
   }
   if(($customer_id == 'X') || ($customer_id == ''))
   {
     //add new customer
     $customer_id =   $this->customers_model->insertCustomer($data);
     redirect("/customer/customerList");
   }else{
     //edit the customer matching the customerID
     $this->customers_model->editCustomer($customer_id, $data);
     redirect("/customer/customerlist");
   }            
}//end validation if 
}//end function

如果用户在邮件选项中选择“是”，我不确定如何将地址，邮政编码和其他字段设为“必需”。

如果有人可以帮助我，那就太好了。

非常感谢

您可以使用回调函数，作为邮件选项验证规则...类似

$this->form_validation->set_rules('mail', 'Mail', 'callback_mail_check');

然后在回调函数中，您可能会有类似

的内容

function mail_check($str)
{
    if ($str == 'YES')
    {
        $this->form_validation->set_message('mail_check', 'You need to fill other fields.');
        return FALSE;
    }
    else
    {
        return TRUE;
    }
}
