处理$ _POST元素以进行AJAX调用以更新MYSQL表

Question

我有一个表单，它从MySQL表中获取输入以显示值，并使用某些操作项更新它。

现在，我正在尝试使用“更新”功能，这样我就可以将表单上的“注释”和“状态”字段更新为最新更改。但是，我的代码有问题。首先，它似乎没有调用“ajax_updateBugStats.php”文件。

结果是它没有在MySQL表中更新。 这是表格：

<form id = "bugStats">
                            <tr>
                                <th>
                                    ID
                                </th>
                                <th>
                                    ISSUE
                                </th>
                                <th>
                                    REFERER
                                </th>
                                <th>
                                    URI

                                </th>
                                <th>

                                </th>

                                </td>
                                <td>
                                    <!-- <input id = "sub" type= "submit" name= "sub" value="UPDATE"/> -->
                                    <input form = "bugStats" type="checkbox" name="action_checkbox['.$id.']" value="'.$id.'"><br>
                                </td>
                            </tr>';

}

这是处理它的ajax调用：

<script>

$("#bugStats").submit(function(event)
{
    var checked = $("#bugStats").serializeArray();
    alert("success");
    $.ajax({
        type: 'POST',
        url: '/ajax_updateBugStats.php',

        data: { checked: checked },
        success: function(server_response)
        {
            if(server_response == "1")
                alert("yes");
            else if (server_response == "0")
                alert("no");
            else
                alert("gro");
        }
        // error: AjaxFailed
    });
});
alert("nice");
</script>

这是ajax调用使用的php文件（ajax_updateBugStats.php）：

<?php
require_once 'wp-config.php';
require_once 'dbinclude.php';

$comments = array();
$status = array();

if (isset($_POST))
{

foreach($_POST['action_checkbox'] as $key => $value)
{
    $id[] = $_POST['bugID'][$key];
    $status[] = $_POST['status'][$key];
    $comments[] = $_POST['comments'][$key];
}
}

$count = count($_POST['action_checkbox']);
for ($x = 0; $x < $count; $x++)
{
$sqlstringWPUsers = "UPDATE bugtracker SET status = '{$status[$x]}', comments = '{$comments[$x]}' WHERE id = '{$id[$x]}'";
$resultWPUsers = mysqli_query($mysqlconn, $sqlstringWPUsers);

}
mysqli_close($con);
