想要将空文本域问题输入到数据库中

我有一个php questionare页面，可以从数据库中生成多个问题。所有的问题都是错误的，但也有一些问题有补充文本字段（见图）。如果填写文本字段（＆＃39; fill_in_quest_text＆＃39;）中包含文本，则响应和文本将保存到msyslq数据库中。但是，如果问题的文本框中没有文字，我不希望回复提供随附的问题编号。我认为有一个简单的解决方案，但我对php的了解不足以了解如何做到这一点 - 即只在文本框中有文本时才将响应插入数据库。

这里提出的问题和填写问题如下：

以下是相关代码，它接收来自_POST变量的响应并将它们放入＆＃34;响应＆＃34;表

foreach( $_POST['question'] as $key => $questionToInsert ) 
{
 $follow = ( isset($_POST['follow'][$key]) ) ? $_POST['follow'][$key] : '';
 $fill_in_quest_text = ( isset($_POST['fill_in_quest_text'][$key]) ) ?
    $_POST['fill_in_quest_text'][$key] : '';
 $q = ( isset($_POST['q'][$key]) ) ? $_POST['q'][$key] : '';

 $query = "insert into responses(userid,question_id,response_main,
    response_followup,category,response_time,unique_session,fill_in_quest_text)
    values('".$_SESSION['userid']."','".$_POST['question'][$key]."', '".$q."',
    '".$follow."','".$_POST["category"]."','".date("Y-m-d")."',
   '".$_SESSION['unique_session']."','".$fill_in_quest_text."')";

 mysql_query($query);
}

以下是浏览器中与上面的屏幕截图对应的html。 （抱歉这个烂摊子）

如果我需要提供更多细节，请告诉我。我认为它也可以用JavaScript来完成，但也无法解决这个问题。

感谢。

您应该能够简单地检查输入的“真实性”。这将消除空字符串""之类的响应，这是您可能从空输入中获得的。

尝试按如下方式修改代码：

$q = ( isset($_POST['q'][$key]) ) ? $_POST['q'][$key] : '';

// Don't store "falsy" $q
if ($q)
{
  $query = "insert into responses(userid, question_id, response_main, response_followup, category, response_time, unique_session, fill_in_quest_text) values ('".$_SESSION['userid']."','".$_POST['question'][$key]."', '".$q."', '".$follow."','".$_POST["category"]."','".date("Y-m-d")."', '".$_SESSION['unique_session']."','".$fill_in_quest_text."')";

  mysql_query($query);
}

更新

根据OP的评论，如果你想保存某些可能为空的字段，你需要以某种方式通知PHP。默认情况下，PHP无法知道数据来自何种类型的输入。实现这一目标的一种方法可能如下：

<input type="text" name="no_save">

<input type="checkbox" name="yes_save" value="1">
<input type="hidden" name="force_save[]" value="yes_save">

<input type="checkbox" name="yes_save2" value="1">
<input type="hidden" name="force_save[]" value="yes_save2">

这里的想法是构建一个我们想要强制存储在DB中的输入数组。然后我们只检查输入键是否在force_save数组中：

// this line:
if ($q) {}
// becomes:
if ($q || in_array($key, $_POST['force_save'])) {}

我认为应该这样做：）

     foreach( $_POST['question'] as $key => $questionToInsert ) 
        {
         $follow = ( isset($_POST['follow'][$key]) ) ? $_POST['follow'][$key] : '';
         $fill_in_quest_text = ( isset($_POST['fill_in_quest_text'][$key]) ) ?
            $_POST['fill_in_quest_text'][$key] : '';
         $q = ( isset($_POST['q'][$key]) ) ? $_POST['q'][$key] : '';

        if($q){
          if(isset($_POST['fill_in_quest_text'][$key]) && $_POST['fill_in_quest_text'][$key]==''){
          //skip
          }else{
            echo 'do'.$_POST['question'][$key].'<br/>'; //for debug purpose
           $query = "insert into responses(userid,question_id,response_main,
              response_followup,category,response_time,unique_session,fill_in_quest_text)
              values('".$_SESSION['userid']."','".$_POST['question'][$key]."', '".$q."',
              '".$follow."','".$_POST["category"]."','".date("Y-m-d")."',
             '".$_SESSION['unique_session']."','".$fill_in_quest_text."')";

          mysql_query($query);
          }
      }

        }
