title: Delete multiple rows if checkbox is checked
body: <p>I want to build a feature that enables the user to moderate questions and is similar to wordpress comment or typical email moderation that uses a checkbox to approve/delete many questions at once.</p>
  
  <p>How would I modify the following code to check which the questions are checked and react to the delete buttons when pressed? You may notice from the below code that I can currently do this with individual questions but I want to give the user more power.</p>
  
  <pre><code> &lt;h2&gt;&lt;a href="#"&gt;Moderate Questions&lt;/a&gt;&lt;/h2&gt;
   &lt;div&gt;
      &lt;button type="button" class="btn" name="delete" id="delete"&gt;Delete&lt;/button&gt;
      &lt;button type="button" class="btn" name="approve" id="approve"&gt;Approve&lt;/button&gt;
    &lt;?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 = $myquestions["dateattime"];
        echo "&lt;div class='question'&gt;";
        echo "&lt;span value='$question_id'&gt;";
     echo "&lt;input name='checkbox' type='checkbox' id='checkbox' value='$question_id'&gt;";
        echo "$question - &lt;span class='date'&gt;Asked $dateattime &lt;/span&gt;";
        echo "&lt;/span&gt;\n";
        echo "&lt;div class='question-controls'&gt;&lt;a href='".$_SERVER["PHP_SELF"]."?delete=$question_id' title='Delete this question' class='delete' onclick='return confirm(\"Are you sure you want to delete this question?\")'&gt;Delete&lt;/a&gt; | &lt;a href='#'&gt;Edit&lt;/a&gt; |";
        echo " &lt;a href='".$_SERVER["PHP_SELF"]."?approve=$question_id' title='Publish this question'&gt;Approve&lt;/a&gt;&lt;/div&gt;";
        echo "&lt;/div&gt;";
      } while ($myquestions = mysql_fetch_array($result));
    } else {
      echo "&lt;p&gt;No one has asked a question recently.&lt;/p&gt;";
    }
    ?&gt;
   &lt;/div&gt;
