防止驗證，當你有隱藏領域Codeigniter

Question

我正在做一個航空公司預訂，我有2個單選按鈕。

1）的一種方法

2）往返

，我所做的就是將事情時，我選擇了往返，所有的字段都存在（出發日期，返回和乘客人數），但我選擇單向單選按鈕時，應該隱藏返回字段。

在我的控制器中，我驗證所有字段都是必需的。問題是，每當我嘗試以單向搜索（返回字段被隱藏）時，它會給我一個「需要返回字段」的錯誤

問題：當我選擇一個時，如何防止返回驗證字段單選按鈕？

控制器

public function search() 
{ 
    $data['countries'] = $this->CrudModel->get('countries'); 
    $this->form_validation->set_error_delimiters('<div class="alert alert-danger" role="alert">', '</div>'); 
    $this->form_validation->set_rules('flight_from', 'Select depature', 'required|trim'); 
    $this->form_validation->set_rules('flight_to', 'Select Destination', 'required|trim'); 

    if ($_POST['flight_type'] == 'round_trip') 
    { 
     $this->form_validation->set_rules('depart', 'Date of flight', 'required|trim'); 
     $this->form_validation->set_rules('return', 'Date of return', 'required|trim'); 
     $this->form_validation->set_rules('no_of_passengers', 'Number of Passengers', 'required'); 
     if ($this->form_validation->run() == FALSE) 
     { 
      $this->index(); 

     } 
     else 
     { 
      $search_result = array(
       $flight_from = $_POST['flight_from'], 
       $flight_to = $_POST['flight_to'], 
       $depart = $_POST['depart'], 
       $return = $_POST['return'], 
       $no_of_passengers = $_POST['no_of_passengers']

     $this->load->view('result',$data); 
     } 

    } 
} 

我的AJAX/JS隱藏的返回字段

<script type="text/javascript"> 
$(document).on('change', 'input:radio[name=flight_type]', function(){ 
    $('div[id^="try"]').toggle(); // hide all DIVs begining with "my_radio_" 
    $('#' + $(this).attr('id') + '_text').show(); // show the current one 
}); 
</script> 

Answer 1

首先你增加價值往返：

<input type="radio" name="flight_type" value="round_trip" class="roundw" style="" checked>Round Trip 

然後做驗證條件如下圖所示：

// Global validation for this method 
if ($_POST['flight_type'] == 'round_trip') 
    { 
     $this->form_validation->set_rules('depart', 'Date of flight', 'required|trim'); 
     $this->form_validation->set_rules('return', 'Date of return', 'required|trim'); 
    } 
    else if($_POST['flight_type'] == 'one_way'){ 
     // add validation for one way trip 
    } 

Answer 2

時您必須在郵寄請求中傳遞flight_type參數。那麼你的代碼將如下所述。

$this->form_validation->set_rules('flight_from', 'Select depature', 'required|trim'); 
$this->form_validation->set_rules('depart', 'Date of flight', 'required|trim'); 

if($this->input->post('flight_type')== 'roundw'): 
    $this->form_validation->set_rules('flight_to', 'Select Destination', 'required|trim'); 
    $this->form_validation->set_rules('return', 'Date of return', 'required|trim'); 
endif:
