在php中向数据库发送复选框值

标签: javascript php mysql checkbox

我的页面中有一个表,它的前两列来自数据库中的表,第三列是复选框,如果用户知道表中显示的单词的含义,请检查它们 我想以这种方式更新数据库中的表:对于选中的复选框,插入1以检查表中的列,否则插入0  如何获取复选框值并将其插入数据库中的右侧行 我现在有这个代码:

    <?php
        $con = mysql_connect("localhost", "root", "")
        or die(mysql_error());   
        if (!$con) { 
            die('Could not connect to MySQL: ' . mysql_error()); 
        } 
        mysql_select_db("project", $con)
        or die(mysql_error());
        $result = mysql_query("select * from words");
        echo "<table border='1'>
           <tr>
              <th>word</th>
              <th>meaning</th>
              <th>checking</th>
            </tr>";
            while($row = mysql_fetch_array($result)) {
                  echo "<tr>";
                    echo "<td>" . $row['word'] . "</td>";
                    echo "<td>". "<div class='hiding' style='display:none'>".$row['meaning']."</div>"."</td>";
                    echo "<td>";
                     echo "<input name=\"fahimeh\" type=\"checkbox\" value=\"\"> ";
                    echo "</td>";
                  echo "</tr>";
                  }
         echo "</table>";
         mysql_close($con);                        
        ?>
        <button onclick="ShowMeanings()">ShowMeanings</button>
        <button onclick="feedback()">sendfeedback</button>  

这是我的javascript代码:

   <script type="text/javascript">
        function ShowMeanings(){
        var hidings = document.getElementsByClassName('hiding');
        for (var i=0; i<hidings.length; i++){
        hidings[i].style.display = 'block';
        }

        }
    </script>

我不知道如何编写反馈(),如何获取复选框值并将其插入数据库中的右行
