如何以單一順序添加更多商品

我有一個頁面book_order.php ...當我填寫詳細信息並提交後，所有詳細信息都保存在一個表order_management中。我想要的是提交後一次，我需要一個彈出窗口詢問「你想添加/預訂更多產品嗎？」如果按是...那個order_id被記住，並且下一次預訂必須在同一個order_id上完成...我怎麼能這樣做....？如何以單一順序添加更多商品

我將數據保存在表「order_management」中，其中我將order_id定義爲自動遞增的字段..我的問題是在我記住下一個事務的order_id之後的一次......我如何將它插入表中？

<?php 

if(isset($_POST['submit'])) 
{ 
extract($_POST); 

$order_date=date("Y-m-d"); 

$sql=mysql_query("select sku,quantity_in_stock,sold_quantity,crdate from stock_info where product_name = '$prod'"); 
$array=mysql_fetch_array($sql); 
$sku = $array[0]; 
$qis = $array[1]; 
$sold_quan = $array[2]; 
$crdate = $array[3]; 

$sql2=mysql_query("INSERT INTO order_management(order_date,brand,product,price,customer_name,phone_number,email,address,quantity,channel,courier,order_status,sku) 
VALUES 
('$order_date','$brand','$prod','$pri','$customername','$phonenumber', '$email','$address','$quantity','$channel','$courier','booked','$sku')"); 



if($sql2) 
{ 
echo "<div class='da-message success'>Successfully Booked Your Order</div>"; 

} 
else 
{ 
die(mysql_error()); 
} 


$quantity_left = $qis - $quantity; 
$sold_quan = $sold_quan + $quantity; 

$diff_in_days = (strtotime($order_date) - strtotime($crdate))/(60 * 60 * 24); 
$expctd_stock=round((7*$quantity_left)/$diff_in_days); 
//echo $expctd_stock; 



$sql3 =mysql_query("UPDATE stock_info SET quantity_in_stock = '$quantity_left',last_sold_date='$order_date', sold_quantity='$sold_quan', expected_stock='$expctd_stock' WHERE sku='$sku'"); 
/*$sql3 = mysql_query("update order_management set sku='$sku' where order_date=''");*/ 

}

你有試過什麼嗎？最好的辦法是用ajax請求提交你的訂單，如果訂單被正確插入，你就會有一個ajax事件在ajax請求成功完成後觸發。在那個事件中你實際上會觸發你的對話框 –

，問題是更新order_id – sashh

HTML

<input type="button" id="btn" name="btn" onclick='return add_data()'/>

<script type="text/javascript"> 
function add_data() 
{ 
    var ans = confirm("Want to add more?"); 
    if(ans) 
    { return true; // ur code for add new data again } 
    else 
    { return false; } 
} 
</script>

你應該使用：

//Retrieve last order ID inserted 
$id = mysql_insert_id();

並將其存儲在$ _SESSION或$ _COOKIE中

您可以將order_id保存在php $_SESSION變量中，並檢查它是否存在。然後在下一個訂單中使用該$orderId。我也建議重構你的代碼，併爲前端添加jQuery，也許把你的代碼放到一個php類中。

更新表中的order_id是最大的問題，因爲它是自動遞增的fied – sashh

從你的描述中讀取，'single booking'是一個訂單獨特的'order_id'和一些數據（產品等）。當你想添加另一個訂單或預訂時，你想保持相同的'order_id'正確嗎？如果以上所有內容都是正確的，那麼您需要修改數據庫表結構以爲獨特的'order_id'提供一個單獨的列，並且可能會添加一個名爲'booking_id'的列？ – Patryk

我創建了一個具有相同結構的新表，其中order_id不是唯一的，並且正在插入它 – sashh
