javascript - 在php中将复选框值发送到数据库

Question

我的页面中有一个表格，它的前两列来自数据库中的表格，第三列用于复选框，如果用户知道表格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，将 1 插入到表中的检查列，否则插入 0 如何获取复选框值并将其插入数据库的右行 到目前为止我有这个代码:

    <?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()，以及如何获取复选框值并将其插入数据库的右行

这应该有效:)

<?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\" name='" . $row['id'] . "' value=\"\"> ";
                    echo "</td>";
                  echo "</tr>";
                  }
         echo "</table>";
         mysql_close($con);                        
        ?>
        <button onclick="ShowMeanings()">ShowMeanings</button>
        <button onclick="feedback()">sendfeedback</button>
