Question

我正在使用动态选择框并获取数据库中的数据，但是我有一个大问题，我无法解决，任何人都可以告诉我或更正我在这里写的错误。因为每次我尝试提交按钮时，只有Product_id保存在数据库中，这是我的代码，我希望它们分别为Product_name，Product_quantity Product_unit，Product_price将存储在数据库中，而不是product_id。

delivery_form.php

<form class="form-horizontal" method="POST" action="deliveryformsave.php" enctype="multipart/form-data">
<tr>
<td align="right"><h3>Product:</h3></td>
</tr>
    <tr>
    <?php
    //Include database configuration file
    include('connect-db.php');

    $query = $DBcon->query("SELECT * FROM product WHERE product_status = 'available' ORDER BY product_name ASC");

    //Count total number of rows
    $rowCount = $query->num_rows;
    ?>

    <select name="item1" id="product" >
        <option value="">Select Country</option>
        <?php
        if($rowCount > 0){
            while($row = $query->fetch_assoc()){ 
                echo '<option value="'.$row['product_id'].'">'.$row['product_name'].'</option>';
            }
        }else{
            echo '<option value="">Product not available</option>';
        }
        ?>
    </select>

    <select name="quantity1" id="quantity">

            </div>
        </div>
    </form>                 

        <script type="text/javascript">
$(document).ready(function(){

        var product_id = $(this).val();
        if(product_id){

            $('#unit').html('<option value="">Select state first</option>');

这是我的ajaxdota2.php

 <?php
//Include database configuration file
include('connect-db.php');

if(isset($_POST["product_id"]) && !empty($_POST["product_id"])){
    //Get all state data

    $query = $DBcon->query("SELECT * FROM product WHERE product_id = ".$_POST['product_id']." AND product_status = 'available' ORDER BY product_quantity ASC");


    //Count total number of rows
    $rowCount = $query->num_rows;

    //Display states list
    if($rowCount > 0){
        echo '<option value="">STOCK</option>';
        while($row = $query->fetch_assoc()){ 
            echo '<option value="'.$row['product_id'].'">'.$row['product_quantity'].'</option>';
        }
    }else{
        echo '<option value="">State not available</option>';
    }
}


if(isset($_POST["product_unit"]) && !empty($_POST["product_unit"])){
    //Get all state data

    $query = $DBcon->query("SELECT * FROM product WHERE product_id = ".$_POST['product_unit']." AND product_status = 'available' ORDER BY product_unit ASC");


    //Count total number of rows
    $rowCount = $query->num_rows;

    //Display states list
    if($rowCount > 0){
        echo '<option value="">UNIT</option>';
        while($row = $query->fetch_assoc()){ 
            echo '<option value="'.$row['product_id'].'">'.$row['product_unit'].'</option>';
        }
    }else{
        echo '<option value="">State not available</option>';

if(isset($_POST["product_price"]) && !empty($_POST["product_price"])){
    //Get all city data


        $query = $DBcon->query("SELECT * FROM product WHERE product_id = ".$_POST['product_price']." ORDER BY product_price ASC");

您的问题尚不清楚，但是如果您希望在deliveryformsave.php中存储产品数据数组，则可以执行以下操作：

echo '<option value="'.$row.'">'.$row['product_name'].'</option>';

通过将整个$ row数组作为option标记的值，它将把$ row中的所有属性发送到您的deliveryformsave.php。在其中，您可以通过将$ row数组的索引设为：

$row['Product_name'];
$row['Product_quantity'];

，依此类推... 希望这会有所帮助。

**更新：查看您的deliveryformsave.php文件，您可以使用：

在$ id [item1]中使用$ row ['Product_name'] 在$ id [quantity1]中使用$ row ['Product_unit'] 以及您需要存储为值的其他字段。

在打印$ row之前，先查看数组是否包含Product_name和其他项。
