我的單選按鈕沒有從foreach循環中獲取值，並且表單驗證返回'field required'，即使它被檢查了嗎？

Question

我正在使用codeigniter。 驗證錯誤一直說“主席字段必需”，盡管在元素檢查中有一個給單選按鈕的值。 所以我想問題是沒有看到單選按鈕輸入字段。

這是我的觀點：

 <form method="" action="" id="vote_results" >

 <?php if (isset($vchairman_records)) : foreach ($vchairman_records as $v_chairman_row) : ?>
 <input type="radio" id="chairman" name="chairman"  value="<?php echo $chairman_row->registration_number ?>" /> 
  <?php endforeach; ?>

     <?php else : ?>
      <p class="">No records were returned</p>
    <?php endif; ?>

 <button type="submit" class="btn btn-success btn-lg alert-info sb_button" id="vote">
  <span id="sending_btn" style="display: none">Sending....</span>
  <span class="" id="profesional-btn">Submit</span>
 </button>
 </form>


## My Controller ##
    $this->form_validation->set_rules('chairman', 'Chairman', 'required|xss_clean');

        if (!$this->form_validation->run() == FALSE) {

            $data = array(
                'success' => FALSE,
                'errors' => validation_errors()
            );


            echo json_encode($dat

您在echo $ chairman_row-> registration_number中缺少分號
