聲明！

最近幾個月，不斷地有站友向我索要完整的代碼，其實之前我是全部粘貼到博客里供大家參考交流的。之所以刪掉一部分，是因為有一些網站全盤照抄并標明為原創，以抄襲獲取流量甚至盈利，違背了我的初衷。

感謝各位不嫌棄我的代碼粗陋。如果還有站友想要源代碼，請在這篇博客下留下自己的聯系方式。但是再次聲明，之前和今后私下從我這里以任何方式要走的代碼，都不能用作商業用途！

請勿轉載！

謝謝！

這是我在研究生期間，老師要求做的一個類似原始淘寶網的購物網站，
因為不會PHP，為了寫這個作業而新學的。
做這個網站用了兩周時間，在此把這個小項目做一個總結。

這個小項目做的時間非常趕，一共兩周，實際有效時間只有10天，中間還在忙其他的事。所以有很多不足之處。
有些代碼原本可以寫的更精簡，合并在一起。
連接數據庫和其他的一些執行sql語句的操作，可以封裝在單獨的文件里面調用，這里也都比較簡單的哪里用到就在哪里處理了。
數據庫的鏈接方式用了兩種，沒有統一。

還是有很多值得改進的地方。

功能：

DONE. 用戶權限管理。包括管理員和普通用戶。管理員有所有權限，包括更新網站狀態
登錄的其他值為用戶名和密碼，用戶名和密碼正確，跳轉到下一頁。
ADMIN具有添加，刪除，更新等權限。用戶只能查看手機，只能添加到購物車中的手機等。

DONE.新用戶：此模塊適用于沒有帳戶的用戶。這里用戶可以創建一個帳戶來登錄。賬戶的創建是通過填寫注冊表單和用戶的詳細信息，如姓名，電話，電子郵件等來完成的。

DONE.產品管理和展示：該模塊展示手機產品信息，如產品編號，項目，名稱，類別，產品圖像，說明，功能和產品限制等。所有這些都將輸入到數據庫，因此可以在網站上找到。

DONE.搜索：該模塊可幫助客戶根據自己的預算或興趣來放松搜索。搜索可以在不同的類別上完成，如品牌，型號名稱，型號，顏色或價格等。

DONE:交易：在此模塊中，購物車的管理已完成。此模塊購物者可以選擇任意數量的物品（手機，配件）并將它們添加到購物車，在從購物車購買物品后，所有要購買的物品都可以再次查看。如果他以后不喜歡，購物者也可以從購物車中取出。購物者還可以逐一檢查購物車中保存的產品。由于產品從購物車中檢出，總價格將相加。

DONE:裝運：在這個模塊中，購物者可以選擇合適的裝運選項。購物者可以使用不同服務提供商提供的各種運送選項。

DONE:付款：該模塊描述了客戶完成的付款。購物者可以選擇不同的支付方式，并根據所選的支付方式的要求提供機密的支付信息。付款信息還可能包括購買型號，數量和供應商名稱等信息。

DONE:報告：在此模塊中，將生成所有報告。無論何時出售物品或客戶訂購產品，都應立即通過電子郵件向其供應商發送警報，以便他可以盡快裝運該物品。該模塊有3個子模塊;股票報告，訂單報告和交付報告。

• 股票報告將生成可用產品數量和產品狀態的報告。
• 訂單報告將列出訂購的產品清單以及購買該產品的客戶詳細信息，這些信息未送達。
• 交付報告將生成已售出產品清單及其交付狀態。

###1.數據庫表設計
下面是對數據庫設計的一個說明，交作業用的。

Design ideas of relational schema:
Since the website will not be too complex, so I just design basic fields of the whole website logic. As for the tables “order_info” and “orderDetailRecord_info”, I separate order information into two tables to solve the problem that one order may have two types of products. Plus, the “p_image_url” field in the table “product_info”, will be used for analyzing url of images of products. Plus plus: actually an order may conclude many products, every products may choose different delivery method, but here we simplify it and assume that an order only have one delivery method.

另外需要說明的是，
delivery_info表和payment_info表中分別加入了一個random字段，是因為在寫php處理的過程中，產生了相應的需要，具體處理請看代碼。

下面是具體的表名和字段：

附上剛開始創建數據表的mysql代碼，后期自此基礎上有一些修改

`admin_info(admin_id,admin_name,admin_pwd)` CREATE TABLE IF NOT EXISTS admin_info(admin_id int(10) NOT NULL AUTO_INCREMENT,admin_name varchar(50) NOT NULL,admin_pwd varchar(50) NOT NULL,PRIMARY KEY(admin_id) );`user_info(u_id,u_name,u_pwd,u_phone,u_email)` CREATE TABLE IF NOT EXISTS user_info(u_id int(10) NOT NULL AUTO_INCREMENT,u_name varchar(50) NOT NULL,u_pwd varchar(50) NOT NULL,u_phone int(50) NOT NULL,u_email varchar(50) NOT NULL,PRIMARY KEY(u_id) );`product_info(p_id, p_name,p_brand, p_type,p_price,p_inventory,p_descr,p_color,p_image_url)` CREATE TABLE IF NOT EXISTS product_info(p_id int(10) NOT NULL AUTO_INCREMENT,p_name varchar(50) NOT NULL,p_brand varchar(50) NOT NULL,p_type int(50) NOT NULL,p_price varchar(50) NOT NULL,p_inventory varchar(50) NOT NULL,p_descr varchar(100) NOT NULL,p_color varchar(50) NOT NULL,p_image_url varchar(200) NOT NULL,PRIMARY KEY(p_id) );`payment_info(pay_id,pay_user,receive_user,pay_account,receive_account,pay_status)` CREATE TABLE IF NOT EXISTS payment_info(pay_id int(10) NOT NULL AUTO_INCREMENT,pay_user varchar(50) NOT NULL,receive_user varchar(50) NOT NULL,pay_account int(50) NOT NULL,receive_account int(50) NOT NULL,pay_status boolean NOT NULL,PRIMARY KEY(pay_id) );`delivery_info(d_id,d_company,d_init_add,d_trgt_add,d_price)` CREATE TABLE IF NOT EXISTS delivery_info(d_id int(10) NOT NULL AUTO_INCREMENT,d_company varchar(50) NOT NULL,d_init_add varchar(50) NOT NULL,d_trgt_add varchar(50) NOT NULL,d_price varchar(50) NOT NULL,PRIMARY KEY(d_id) );`order_info(o_id,u_id,d_id,o_date,pay_id)` CREATE TABLE IF NOT EXISTS order_info(o_id int(10) NOT NULL AUTO_INCREMENT,u_id int NOT NULL,d_id int NOT NULL,o_date int(50) NOT NULL,pay_id int NOT NULL,PRIMARY KEY(o_id),FOREIGN KEY (u_id) REFERENCES user_info(u_id),FOREIGN KEY (d_id) REFERENCES delivery_info(d_id),FOREIGN KEY (pay_id) REFERENCES payment_info(pay_id) );`orderDetailRecord_info(r_id,o_id,p_id,p_num)` CREATE TABLE IF NOT EXISTS orderDetailRecord_info(r_id int(10) NOT NULL AUTO_INCREMENT,o_id int NOT NULL,p_id int NOT NULL,p_num int(50) NOT NULL,PRIMARY KEY(r_id),FOREIGN KEY (o_id) REFERENCES order_info(o_id),FOREIGN KEY (p_id) REFERENCES product_info(p_id) );`stock_info(s_id,p_id,p_inventory)` CREATE TABLE IF NOT EXISTS stock_info(s_id int(10) NOT NULL AUTO_INCREMENT,p_id int(10),p_inventory int(50),PRIMARY KEY(s_id),FOREIGN KEY(p_id) REFERENCES product_info(p_id) );

下面是以上功能的代碼以及一些相關的解釋：
最簡單的主界面：
index.html
//只放了一個注冊一個登錄的鏈接

<html> <head> <meta charset="utf-8"> <title>Phones on saling</title> </head> <h1>Phones on saling!</h1><a href="chooseCharactor.html" target="_blank">Sign in the website.</a><br><br><a href="login.php" target="_blank">Login into the website.</a> </html>

###1.注冊功能：
首先要選擇角色類型：（這個功能是剛開始練習做的，其實應該把角色選擇和注冊功能都放在一個頁面里，現在分為了三個，分別是選擇，管理員注冊和用戶注冊，比較麻煩。后來時間緊，就沒有再改了，實際可以合并為一個。）

chooseCharacter.html

<html> <head><meta charset="utf-8"><title>Sign in to phone website</title> </head> <h1>Choose your charactor</h1>Please choose which kind of charactor you want to sign in?<form action="chooseCharactor.php" method="get"><select name="q"><option value="">Choose charactor</option><option value="admin">Admin</option><option value="user">User</option></select><br><input type="submit" value="Submit"></form> </html>

chooseCharacter.php
//選擇相應的角色后，會跳轉到不同角色的注冊界面

<!DOCTYPE html> <html> <head><title>Choose charactor</title> </head> <body><?php$q = isset($_GET['q'])? htmlspecialchars($_GET['q']) : '';if($q == "") {echo "You must choose a charactor!";}else if($q != ""){if($q =='admin') {header('Location: adminSign.html');} else if($q =='user') {header('Location: sign.html');}}?> </body> </html>

1）管理員注冊：
adminSign.html
//管理員注冊的界面。管理員注冊需要拿到內部的Invitation number(邀請碼)，注冊方可進行。如果已經注冊，可以點擊下方的login鏈接，直接登錄，將跳轉到login.php界面。

<html> <head><meta charset="utf-8"><title>Sign in to phone website as admin user</title> </head> <h1>Sign in</h1><form action="adminSign.php" method="post">User name:<input type="text" name="username"><br>User password:<input type="password" name="psw"><br>Confirm user password:<input type="password" name="cofpsw"><br>Invitation number:<input type="text" name="invtnum"><br><input type="submit" name="submit"></form>If you have already signed in, please click here to login.<br><a href="login.html" target="_blank">Login into the website.</a> </html>

adminSign.php
//處理管理員注冊請求

<!DOCTYPE html> <html> <head><title>Sign in the phone web as admin user, success!</title> </head> <body><?phpinclude 'executeSql.php';$userName = $_POST["username"];$pwd = $_POST["psw"];$cofPsw = $_POST["cofpsw"];$invtNum = $_POST["invtnum"];if($userName == ""||$pwd == ""||$cofPsw == ""|| $invtNum == ""){echo "None of the value can be empty!";}else if($pwd != $cofPsw){echo "The password entered for two time is not same!";}else if($invtNum != "SN90IE58KP"){echo "The invitation number is wrong!"; }else{echo "All values are right, your have sucessfully sign in as admin user!";$sql = "INSERT INTO admin_info (admin_name,admin_pwd) VALUES('" . $userName . "','" . $pwd . "');";//$sql = "INSERT INTO admin_info (admin_name,admin_pwd) VALUES('superadmin','admin123');";//echo $sql;executeSql($sql);}?> </body> </html>

2）用戶注冊
sign.html
//用戶注冊界面

<html> <head> <meta charset="utf-8"> <title>Sign in to phone website</title> </head> <h1>Sign in</h1> <form action="sign.php" method="post">User name:<input type="text" name="username"><br>User password:<input type="password" name="psw"><br>Confirm user password:<input type="password" name="cofpsw"><br>Phone:<input type="text" name="phone"><br>Email:<input type="email" name="email"><br><input type="submit" name="submit"> </form> </html>

sign.php
//處理用戶注冊請求，收集基本信息并加入到數據庫。如果存在數據缺失，則不能注冊，對兩次輸入的密碼做了基本的檢測，并檢測郵箱格式的正確性。
//注冊后會跳轉到login.php界面，但是因為普通用戶注冊后，會自動為當前用戶登錄，并在當前的cookie中存儲用戶登錄的狀態，因此不需要再登錄一次，可以直接由網頁鏈接跳轉到手機購買界面。

<!DOCTYPE html> <html> <head><meta charset="utf-8"><title>Sign in sucess!</title><style>.button {background-color: #4CAF50;border: none;color: white;padding: 15px 32px;text-align: center;text-decoration: none;display: inline-block;font-size: 16px;margin: 4px 2px;cursor: pointer;}.table{border-style:solid;border-color:#98bf21;align-self: center;align-items: center;}/*.divcss5-right{width:320px; height:120px;border:1px solid #F00;float:right} */.divcss5-right{float:right;} /* css注釋：對divcss5-right設置float:right即可讓對象靠右浮動 */</style> </head> <body><?phpfunction executeSql($sql){$flag = false;$feedback = array();if($sql == ""){echo "Error!

"','" . $email . "');";$result = executeSql($sql);if($result){$select_sql = "SELECT u_id FROM user_info WHERE u_name = '".$userName."';";$result = executeSql($select_sql);if($result[0]){setcookie('login_status',true);while($row = mysqli_fetch_assoc($result[1])){$u_id=$row["u_id"];setcookie('u_id',$u_id);}header("location:login.php");}}}?> </body> </html>

###2.登錄功能：
login.php
//用戶登錄的界面，可以選擇管理員用戶登錄和普通用戶登錄。
作為管理員用戶登錄后，跳轉到產品管理界面。作為普通用戶登錄后，跳轉到網站主頁，即手機購買界面。

<html> <head> <meta charset="utf-8"> <title>Login in to phone website</title> <style>.button {background-color: #4CAF50;border: none;color: white;padding: 15px 32px;text-align: center;text-decoration: none;display: inline-block;font-size: 16px;margin: 4px 2px;cursor: pointer;align-self:right;float: left;}.body{font-family:Arial,Helvetica,sans-serif;font-size:20px;}</style> <h2>User Login</h2> </head><body class = "body"><?phpif(isset($_COOKIE['login_status'])){echo "Login already.";?><br><br><a href='showPhones.php'>Click here to buy phones.</a><?php}else{?><form action="process_login.php" method="post"><select name="character"><option value="">Choose your character</option><option value="admin">admin</option><option value="user">user</option></select><br>User name:<input type="text" name="username"><br>User password:<input type="password" name="psw"><br><input type="submit" class = "button" name="submit" value="Choose"></form><?php}?></body> </html>

###3.手機產品管理（管理員）：
1)增加新的手機：
add_product.html
//增加新的手機庫存

<html> <head><title>Add new product</title><style>.button {background-color: #4CAF50;border: none;color: white;padding: 15px 32px;text-align: center;text-decoration: none;display: inline-block;font-size: 16px;margin: 4px 2px;cursor: pointer;align-self:right;float: right;}.table{border-style:solid;border-color:#98bf21;align-self: center;align-items: center;width: "12%";height: "20%";}</style> </head> <h1 align="center">Hello admin user, you can add a new product into database!</h1> <body><form action="add_product.php" method="post"><table align="center" class = "table" border="1"><th>Product Name</th><th>Product Brand</th><th>Product Type</th><th>Product Price</th><th>Product Inventory</th><th>Product Description</th><th>Product Color</th><th>Product Url</th><tr><td><input type="text" name="name"></td><td><input type="text" name="brand"></td><td><input type="text" name="type"></td><td><input type="text" name="price"></td><td><input type="text" name="inventory"></td><td><input type="text" name="descr"></td><td><input type="text" name="color"></td><td><input type="text" name="url"></td></tr></table><input type="submit" class = "button" name="submit" value="Submit"></form> </body> </html>

界面如圖所示（縮小版的界面）

4.用戶購買手機

手機展示界面，并可實現增加產品到購物車，沒有實現批量添加，每點擊一次手機產品對應的添加按鈕，則購物車中增加一條該產品的記錄。
添加后會在購物車功能模塊處理，如果已經添加夠了，也可以直接點擊頁面最下方的鏈接，查看購物車。

showPhones.php

###10.搜索功能
做了一個分類搜索的功能，用的就是數據庫的模糊查詢，很簡單
1）search.html
//頁面

<html> <head> <meta charset="utf-8"> <title>Search phones</title> </head> <h1>Search what you want</h1><form action="search.php" method="post"><select name="select_condition"><option value="">Choose a condition</option><option value="brand">Brand</option><option value="name">Product Name</option><option value="type">Type</option><option value="color">Color</option><option value="price">Price</option></select><br><br>Enter your condition here:<br><input type="text" name="value"><br><br>If you choose price, please enter the price range here:<br>Low range:<input type="text" name="low_range"><br>High range:<input type="text" name="high_range"><br><input type="submit" name="submit" value="Submit"></form> </html>

2）search.php
//處理查詢請求

<!DOCTYPE html> <html> <body> <?phpif(isset($_POST["submit"])){$selected_Condition = $_POST["select_condition"];}else{echo "No condition selected!";echo "<br>";}if($selected_Condition == "brand"){$value = $_POST["value"];if($value ==""){echo "The value can't be empty!";echo "<br>";}else{$sql = "SELECT * FROM product_info WHERE p_brand LIKE '%".$value."%';";showResult($sql);}}else if($selected_Condition == "name"){$value = $_POST["value"];if($value ==""){echo "The value can't be empty!";echo "<br>";}else{$sql = "SELECT * FROM product_info WHERE p_name LIKE '%".$value."%';";showResult($sql);}}else if($selected_Condition == "type"){$value = $_POST["value"];if($value ==""){echo "The value can't be empty!";echo "<br>";}else{$sql = "SELECT * FROM product_info WHERE p_type LIKE '%".$value."%';";showResult($sql);}}else if($selected_Condition == "color"){$value = $_POST["value"];if($value ==""){echo "The value can't be empty!";echo "<br>";}else{$sql = "SELECT * FROM product_info WHERE p_color LIKE '%".$value."%';";showResult($sql);}}else if($selected_Condition == "price"){$low_range = $_POST["low_range"];$high_range = $_POST["high_range"];if($low_range ==""||$high_range == ""){echo "The range can't be empty!";echo "<br>";}else{$sql = "SELECT * FROM product_info WHERE p_price BETWEEN ".$low_range." AND ".$high_range.";";showResult($sql);}}function showResult($sql){$servername = "localhost";$username = "root";$password = "";$dbname = "hw";$conn = mysqli_connect($servername, $username, $password, $dbname);// Check connectionif (mysqli_connect_errno()){echo "Failed to connect to MySQL: " . mysqli_connect_error();}$result=mysqli_query($conn,$sql);//result is a PHP array$num_rows=mysqli_num_rows($result);mysqli_close($conn);if($num_rows == 0){echo "There is no meeted results.";}else{echo '<table border="1">';echo "<tr>";echo "<th>Product Name</th>";echo "<th>Product Brand</th>";echo "<th>Product Type</th>";echo "<th>Product Price</th>";echo "<th>Product Description</th>";echo "<th>Product Color</th>";echo "<th>Product Image</th>";echo "</tr>";$i=0;while ($row = mysqli_fetch_assoc($result)){$p_name=$row["p_name"];$p_brand=$row["p_brand"];$p_type=$row["p_type"];$p_price=$row["p_price"];$p_descr=$row["p_descr"];$p_color=$row["p_color"];$p_image_url = $row["p_image_url"];echo "<tr>";echo "<td>".$p_name."</td>";echo "<td>".$p_brand."</td>";echo "<td>".$p_type."</td>";echo "<td>".$p_price."</td>";echo "<td>".$p_descr."</td>";echo "<td>".$p_color."</td>";$imageData = base64_encode(file_get_contents($p_image_url));echo '<td>[外鏈圖片轉存失敗(img-CAzDYQv5-1562059529498)(data:image/jpeg;base64,'.$imageData.')]</td>';echo "</tr>";$i++;}echo "</table>";}}?></body> </html>

####特別說明：
1）購物車用session實現
2）其他各種用戶登錄狀態，產品id等信息，均存儲在cookie數組中
3）當某種產品賣出后，會從數據庫中將該產品的庫存減去訂單中相應的數量。
