投票选项添加操作

这里需要对已经添加的投票问题进行全部查询展示:

<?php
<select style="width:300px;" name="subject">
   <option value="" checked>请选择问题</option>
<?php
   $result = $db->query("select * from votename");
   while($row = mysqli_fetch_assoc($result)){
?>
   <option value="<?php echo $row['cid']; ?>"><?php echo $row['question_name']; ?></option>
<?php
   }
?>
</select>

全部代码:

<?php
   include('../conn.php');
   if(isset($_POST['voteoption'])?$_POST['voteoption']:''){
      $voteoption = $_POST['voteoption'];
      $subject = $_POST['subject'];
      if($subject == ""){
         echo "<script>onload = function(){document.getElementById('errortext').innerHTML='请选择问题!';}</script>";
      }else{
         $result = $db->query("insert into voteoption (optionname, upid, votenum) values ('$voteoption', '$subject', '0')");
         if($result){
            echo "<script>onload = function(){document.getElementById('errortext').innerHTML='添加选项成功';}</script>";
         }else{
            echo "<script>onload = function(){document.getElementById('errortext').innerHTML='添加选项失败';}</script>";
         }
      }
   }
?>
