我在数组中有一个html重复值，我需要更新到数据库，我需要一个帮助，如何使用PHP脚本更新到staffid mataches数据库。请参阅下面的我的HTML代码

请帮助。我希望SQL更新查询看起来像

"Update payroll SET salary ='".$_POST['salary']."', tax='".$_POST['tax']."', total ='".$_POST['total']."' WHERE staffid= '".$_POST['staffid']."'"

我建议重命名输入名称以创建包含所需信息的单个数组。使用人员ID作为数组键。

<!--Staff 1-->
<tr data-id="STAFF/2016/001">
    <td>
        <input type="text" name="staff[STAFF/2016/001][id]" class="staffid" value="STAFF/2016/001" readonly="readonly">
    </td>
    <td>
        <input type="text" name="staff[STAFF/2016/001][salary]" class="salary" placeholder="salary" value="5000">
    </td>
    <td>
        <input type="text" name="staff[STAFF/2016/001][tax]" class="tax" placeholder="tax" value="500">
    </td>
    <td>
        <input type="text" name="staff[STAFF/2016/001][total]" class="total" placeholder="total" readonly="readonly" value="4500">
    </td>
</tr>

<!--Staff 2-->

<tr data-id="STAFF/2016/002">
    <td>
        <input type="text" name="staff[STAFF/2016/002][id]" class="staffid" value="STAFF/2016/002" readonly="readonly">
    </td>
    <td>
        <input type="text" name="staff[STAFF/2016/002][salary]" class="salary" placeholder="salary" value="10000">
    </td>
    <td>
        <input type="text" name="staff[STAFF/2016/002][tax]" placeholder="tax" class="tax" value="1000">
    </td>
    <td>
        <input type="text" name="staff[STAFF/2016/002][total]" placeholder="total" class="total" readonly="readonly" value="9000">
    </td>
</tr>

在PHP中，您可以迭代这个单个数组：

<?php

$db = new PDO('mysql:host=localhost;dbname=database;', 'root', '');

if (!empty($_POST['staff'])) {
    $stmt = $db->prepare('UPDATE payroll SET salary = :salary, tax = :tax, total = :total WHERE staffid = :staffid');

    foreach ((array)$_POST['staff'] as $staffId => $staffInfo) {

        $stmt->bindValue(':salary', $staffInfo['salary']);
        $stmt->bindValue(':tax', $staffInfo['tax']);
        $stmt->bindValue(':total', $staffInfo['total']);
        $stmt->bindValue(':staffid', $staffId); // you can also use $staffInfo['id'] here instead of $staffId

        $stmt->execute();
    }
}
