Question

我有一个网页，其目的是编辑数据库中的条目。它使用PHP填充，但我需要用户能够更改这些值并使用新值更新数据库。

我遇到的问题是当我将数据从表单发送回数据库时，不使用新信息，而是使用PHP。我该如何解决这个问题？

使用php：

从文本框中填充每个下拉列表，文本框和文本字段

<div class="col-lg-6">
<div class="form-group">
    <label>Version</label>
    <input type="text" class="form-control" name="forensic_tool_version" placeholder="Version" value="<?php
                $session_name = $_SESSION['first_name']." ".$_SESSION['surname'];
                $sql_query = "SELECT fi_forensic_tool_ver FROM asset_tracker WHERE asset_id = ? LIMIT 1";
                $db_field = "fi_forensic_tool_ver";
                $asset_id = $_GET['assetid'];

                get_db_field($mysqli, $sql_query, $db_field, $asset_id, $session_name);
        ?>"/>
</div>

get_db_field只获取数据并将其回显到屏幕。一切正常。

然后，用户将更改一个或多个字段，然后单击“提交”，将进行以下更新：

                <!-- DATABASE INPUT - Input form elements into database -->
                <?php
                    if(!empty($_GET['requestor']) ){



                        $asset_id = $_GET['assetid'];
                        $add_requestor = $_GET['requestor'];
                        $add_kc_number = $_GET['kc_number'];
                        $add_project_name = $_GET['project_name'];
                        $add_custodian = $_GET['custodian'];
                        $add_business_area = $_GET['business_area'];
                        $add_task = $_GET['task'];
                        $add_utl_reference = $_GET['utl_reference'];
                        $add_purchase_price_value = $_GET['purchase_price_value'];
                        $add_request_date = $_GET['request_date'];
                        $add_return_date = $_GET['return_date'];

                        $add_device_type = $_GET['device_type'];
                        $add_manufacturer = $_GET['manufacturer'];
                        $add_username = $_GET['username'];
                        $add_model = $_GET['model'];
                        $add_pinOrPassword = $_GET['pinOrPassword'];
                        $add_vf_asset_num = $_GET['vf_asset_num'];
                        $add_serial_num = $_GET['serial_num'];
                        $add_imei = $_GET['imei'];

                        $add_forensic_tool = $_GET['forensic_tool'];
                        $add_forensic_tool_version = $_GET['forensic_tool_version'];
                        $add_bitlocker_key = $_GET['bitlocker_key'];
                        $add_image_verified = $_GET['image_verified'];

                        $add_case_notes = $_GET['case_notes'];
                        $add_case_photos = $_GET['case_photos'];

                        if($query = $mysqli->prepare("UPDATE asset_tracker SET ci_requesting_employee=?, ci_kc=?, ci_project_name=?, ci_custodian=?, ci_business_area=?, ci_task=?, ci_utl_reference=?, ci_purchase_price_value=?, ci_date_requested=?, ci_date_returned=?, di_type=?, di_manufacturer=?, di_model=?, di_username=?, di_password=?, di_vf_asset=?, di_serial=?, di_imei=?, fi_forensic_tool=?, fi_forensic_tool_ver=?, fi_bitlocker_key=?, fi_image_verified=?, cn_notes=?, cn_photos=? WHERE asset_id = ? LIMIT 1")){
                            $query->bind_param('ssssssssssssssssssssssssi', $add_requestor, $add_kc_number, $add_project_name, $add_custodian, $add_business_area, $add_task, $add_utl_reference, $add_purchase_price_value, $add_request_date, $add_return_date, $add_device_type, $add_manufacturer, $add_username, $add_model, $add_pinOrPassword, $add_vf_asset_num, $add_serial_num, $add_imei, $add_forensic_tool, $add_forensic_tool_version, $add_bitlocker_key, $add_image_verified, $add_case_notes, $add_case_photos, $asset_id);
                            $query->execute();
                            $query->close();
                            echo "<script type='text/javascript'>alert('Asset updated Successfully');</script>";
                        }else{
                            echo "<script type='text/javascript'>alert('Cannot access database');</script>";
                        }
                    }else{
                        //echo "<script type='text/javascript'>alert('Post not set');</script>";
                    }
                ?>

对此的任何帮助将不胜感激！谢谢！
