標籤 php 編寫自助下單系統第三方支付實例欄目 PHP 简体版

此項目是因爲本人剛剛入門php且在校代刷網課而編寫的，因爲在上課時間不方便接單，故特地寫一個自助下單系統來實現客戶自助下單。
本項目主要實現如下功能：
1.用戶下單
2.用戶支付
3.用戶經過帳號查詢訂單
4.管理員登陸查看全部訂單

設計思路：項目比較簡單，基本就是與數據庫之間的通訊，進行數據的增刪改查。支付使用的是第三方支付接口。

如下是具體代碼：
用戶提交訂單頁面

數據庫鏈接頁面

11     }

支付用的是第三方支付接口，由於本案例比較簡單（主要是本人暫時用不來api）因此直接使用了它提供的Demojava

（此處使用的是小叮噹支付）mysql

如下是Demo內容（Demo中的主頁被我合併到add.php中了，就是add.php中的html部分）：

pay.php

jquery

 6     //從網頁傳入money:支付價格， pay_type:支付渠道：43-支付寶；44-微信支付
 7     $order_no = date('Ymd') . str_pad(mt_rand(1, 99999), 5, '0', STR_PAD_LEFT);    //訂單號
 8     $subject = '商品名稱';
 9     $pay_type = $_GET["pay_type"];
10     $money = $_GET["money"];
11     $extra = "";
12     
13     $sign = md5("order_no=" . $order_no . "&subject=" . $subject . "&pay_type=" . $pay_type . "&money=" . $money . "&app_id=" . $app_id . "&extra=" . $extra . "&" . $app_secret);
14     //常常遇到有研發問爲啥sign值返回錯誤，大多數緣由：1.參數的排列順序不對；2.上面的參數少傳了，可是這裏的sign值又帶進去計算了，致使服務端sign算出來和你的不同。
15 
16     $returndata['order_no'] = $order_no;
17     $returndata['subject'] = $subject;
18     $returndata['pay_type'] = $pay_type;
