如何将表单复选框处理成mysql？

Question

我想将已处理的选定值从我的数据库中获取？怎么能实现呢？

我只是将一个结果存储到数据库中。我的目标是每个用户都可以从他们帐户下的收据编号列表中进行多项选择，然后当他们提交请求时，我想在数据库中获取所选的收据编号。

这是我的表格。

<form action="" method="post">
            <div class="modal-body">

                    <div class="row">

                    </div>



            </div>
            <div class="modal-footer">

            </div>

这是我的数据库连接：

    // New shipment Request
if (isset($_POST['submit']) && $_POST['submit'] == 'requestShipment') {
    // Validation
    if($_POST['warehouse'] == "") {
        $msgBox = alertBox($projTitleReq, "<i class='fa fa-times-circle'></i>", "danger");
    } else if($_POST['shipmentAddress'] == "") {
        $msgBox = alertBox($addressStreetWarning, "<i class='fa fa-times-circle'></i>", "danger");
    } else {
        $warehouse = $_POST['warehouse'];
        $shipmentAddress = $_POST['shipmentAddress'];
        $requestDate = date("Y-m-d H:i:s");

        $stmt = $mysqli->prepare("
                            INSERT INTO
                                shipmentrequest(
                                    clientId,
                                    warehouse,
                                    shipmentAddress,
                                    requestDate
                                ) VALUES (
                                    ?,
                                    ?,
                                    ?,
                                    ?
                                )");
        $stmt->bind_param('ssss',
            $clientId,
            $warehouse,
            $shipmentAddress,
            $requestDate
        );

    }
}
