试图从选中的复选框中获取POST，并将用户id对应的用户数据加载到Modal中

我正在尝试制作一个支持票系统。https://gyazo.com/f87fde8cfacf2165a373f409954cf653。

当一个复选框被选中时，它选择用户ID(工作)。但我想做到这一点，当绿色回复按钮被点击时，他们有一个用户选择，抓住他们的信息对应于他们的用户id，这样我就可以显示所有的支持票，他们已经打开。所以我可以通过模态添加另一个回复。像这样:https://gyazo.com/6fb77589606b1e24160c52885b987624。但在本例中，我使用的是静态用户名获取。如……FROM support WHERE postd_by = 'Chowderrunnah'。Chowderrunnah是用户名

我希望它通过选中的复选框(工作)获得用户id，并使其抓住他们打开的所有支持票。

这是我的phpmyadmin数据库:https://gyazo.com/f9eb86e2877979182f6a2a35cb6ed5df

下面是我的代码，我(试图)做什么，但不工作

页顶在php标记

function grab_selected_users_support() {
global $con;
global $user_reply_id;
    $username           = $_SESSION['username'];
    $users_support_sql   = "SELECT id, message, posted_by, last_post_by, date_posted, status FROM support WHERE posted_by = 'Chowderrunnah' ORDER BY id DESC";
    $result             = $con->query($users_support_sql) or die("Error");
        while ($row = mysqli_fetch_assoc($result)) {
            $usersSupport_id            = $row['id'];
            $usersSupport_message       = $row['message'];
            $usersSupport_posted_by     = $row['posted_by'];
            $usersSupport_last_post_by  = $row['last_post_by'];
            $usersSupport_date_posted   = $row['date_posted'];
            $usersSupport_status        = $row['status'];
            ?>
                <div class="well well-sm col-lg-12 pull-left">
                    <span><strong><?php echo $usersSupport_last_post_by ?></strong>: <?php echo $usersSupport_message; ?><br><br><?php echo $usersSupport_status == 'Open' ? '<span class="label label-success">Open</span>' : '<span class="label label-danger">Closed</span>' ?></b><hr><i><?php echo $usersSupport_date_posted; ?></i></span>
                </div>
                <?php ;
        }
}

My PHP检查

<?php 
if(isset($_POST['bulk_delete_submit'])) {
    if(!empty($_POST['checked_id'])) {
        $idArr = $_POST['checked_id'];
        $username = $_SESSION['username'];
        foreach($idArr as $id) {
            mysqli_query($con, "DELETE FROM support WHERE id = '$id'");
            echo "<p>".$id ."</p>";
        }
        $_SESSION['success_msg'] = 'Support Ticket have been deleted successfully.';
        header("Location: admin_support.php");
    }
    else { 
        echo '<div class="row" style="color: red; text-align: center; padding-bottom: 20px;"><i class="fa fa-spin fa-spinner"></i> You must select atleast one support ticket to delete <i class="fa fa-spin fa-spinner"></i></div>';
    }
}
if(isset($_POST['add_reply_submit'])) {
    if(!empty($_POST['checked_id'])) {
        $idArrr = $_POST['checked_id'];
        $username = $_SESSION['username'];
        foreach($idArrr as $idd) {
            $user_reply_id = mysqli_query($con, "SELECT posted_by FROM support WHERE id = '$idd'");
        }
    }
    else { 
        echo '<div class="row" style="color: red; text-align: center; padding-bottom: 20px;"><i class="fa fa-spin fa-spinner"></i> You must select atleast one support ticket to reply to <i class="fa fa-spin fa-spinner"></i></div>';
    }
}
