如果在 html 表中选中复选框，那么我想在按下更新按钮时更新该行的值

Question

这是我提取的表格，我已经为每一行添加了复选框，现在我想更新此表格，如果特定字段被选中，请建议我一些东西`while($record=mysql_fetch_array($res)){

echo "<tr align='center'>";
echo "<td>".$record['YourName']."</td>";
echo "<td>".$record['FatherName']."</td>";
echo "<td>".$record['RegNum']."</td>";
echo "<td>".$record['Gender']."</td>";
echo "<td name='$i' >".$record['MobileNumber']."</td>";

echo "<td>".$record['Password']."</td>";
echo "<td>".$record['specialist']."</td>";
echo "<td>".$record['area']."</td>";
echo "<td>".$record['building']."</td>";
echo "<td>".$record['room']."</td>";
echo "<td><input type='checkbox' name='$i' value='Bike' align='center'></td>";
echo "</tr>";

$i++;

这是获取的数据和复选框。

Answer 1

你的设计需要改变，做类似的事情

echo "<tr align='center'>";
echo "<td>".$record['YourName']."</td>";
echo "<td>".$record['FatherName']."</td>";
echo "<td>".$record['RegNum']."</td>";
echo "<td>".$record['Gender']."</td>";
echo "<td name='$i' >".$record['MobileNumber']."</td>";

echo "<td>".$record['Password']."</td>";
echo "<td>".$record['specialist']."</td>";
echo "<td>".$record['area']."</td>";
echo "<td>".$record['building']."</td>";
echo "<td>".$record['room']."</td>";
echo "<td><a href='edit.php?id={you id for record}'>Edit</a></td>";
echo "</tr>";

它看起来像

Answer 2

jQuery 是您的解决方案。 看看这个页面

你可以像在这里一样实现它

$(document).ready(function() { //set initial state. $('#textbox1').val($(this).is(':checked')); $('#checkbox1').change(function() { if($(this).is(":checked")) { var returnVal = confirm("Are you sure?"); $(this).attr("checked", returnVal); } $('#textbox1').val($(this).is(':checked')); }); });

Answer 3

因为，没有提供数据库表结构。 我假设：主键和自动递增列名称为user_id 。 （更改它，如果您有其他列名）。

<form method='POST' action='approve.php'>
    <table>
        <?
        $i=1;
        while($record=mysql_fetch_array($res)){
            echo "<tr align='center'>";
                echo "<td>".$record['YourName']."</td>";
                echo "<td>".$record['FatherName']."</td>";
                echo "<td>".$record['RegNum']."</td>";
                echo "<td>".$record['Gender']."</td>";
                echo "<td name='$i' >".$record['MobileNumber']."</td>";

                echo "<td>".$record['Password']."</td>";
                echo "<td>".$record['specialist']."</td>";
                echo "<td>".$record['area']."</td>";
                echo "<td>".$record['building']."</td>";
                echo "<td>".$record['room']."</td>";
                // Pay Attention Here in this checkbox. 
                echo "<td><input type='checkbox' name='Approve[]' value='".$record['user_id']."' align='center'></td>";
            echo "</tr>";
        $i++;
        }?>
    </table>
</form>

批准.php

<?php
$countApprovedCheckbox = sizeof($_POST['Approve']);

for($i=0;$i<$countApprovedCheckbox;$i++) {

    $userID = $Approve[$i];

    $query = "UPDATE TableName SET ApproveColumnName='Approve' WHERE user_id='$userID'";
    //Execute Your Query Here.

}
?>
