如果选中复选框，则删除多行

Question

我想构建一个功能，使用户能够审核问题，类似于 WordPress 评论或典型的电子邮件审核，使用复选框一次批准/删除许多问题。

我如何修改以下代码来检查哪些问题被选中并对按下删除按钮做出反应？您可能会从下面的代码中注意到，我目前可以针对个别问题执行此操作，但我想赋予用户更多权力。

 <h2><a href="#">Moderate Questions</a></h2>
 <div>
    <button type="button" class="btn" name="delete" id="delete">Delete</button>
    <button type="button" class="btn" name="approve" id="approve">Approve</button>
  <?php

  // Select all unapproved questions in db 
  $sql = "SELECT question_id, question, DATE_FORMAT(question_date, '%e %b %Y at %H:%i') AS dateattime FROM questions WHERE question_approved='0' ORDER BY question_date DESC";
  $result = mysql_query($sql);
  $myquestions = mysql_fetch_array($result);

  if($myquestions) {
    do {
      $question_id = $myquestions["question_id"];
      $question = $myquestions["question"];
      $dateattime = $myquestions["dateattime"];
      echo "<div class='question'>";
      echo "<span value='$question_id'>";
   echo "<input name='checkbox' type='checkbox' id='checkbox' value='$question_id'>";
      echo "$question - <span class='date'>Asked $dateattime </span>";
      echo "</span>\n";
      echo "<div class='question-controls'><a href='".$_SERVER["PHP_SELF"]."?delete=$question_id' title='Delete this question' class='delete' onclick='return confirm(\"Are you sure you want to delete this question?\")'>Delete</a> | <a href='#'>Edit</a> |";
      echo " <a href='".$_SERVER["PHP_SELF"]."?approve=$question_id' title='Publish this question'>Approve</a></div>";
      echo "</div>";
    } while ($myquestions = mysql_fetch_array($result));
  } else {
    echo "<p>No one has asked a question recently.</p>";
  }
  ?>
 </div>

Answer 1

您需要修改“checkbox”元素才能创建值数组。代码：

echo "<input name='checkbox[]' type='checkbox' id='checkbox' value='$question_id'>";

之后你可以从 php 代码调用这个变量（例如使用 $_REQUEST['checkbox']），它将是数组。因此您可以迭代它并从数据库中删除这些行。
