这篇文章介绍的内容是关于PHP实现购物网站 ，有着一定的参考价值，现在分享给大家，有需要的朋友可以参考一下
这是我在研究生期间，老师要求做的一个类似原始淘宝网的购物网站，因为不会PHP，为了写这个作业而新学的。做这个网站用了两周时间，在此把这个小项目做一个总结。
功能：
DONE. 用户权限管理。包括管理员和普通用户。管理员有所有权限，包括更新网站状态
登录的其他值为用户名和密码，用户名和密码正确，跳转到下一页。
ADMIN具有添加，删除，更新等权限。用户只能查看手机，只能添加到购物车中的手机等。
DONE.新用户：此模块适用于没有帐户的用户。这里用户可以创建一个帐户来登录。账户的创建是通过填写注册表单和用户的详细信息，如姓名，电话，电子邮件等来完成的。
DONE.产品管理和展示：该模块展示手机产品信息，如产品编号，项目，名称，类别，产品图像，说明，功能和产品限制等。所有这些都将输入到数据库，因此可以在网站上找到。
DONE.搜索：该模块可帮助客户根据自己的预算或兴趣来放松搜索。搜索可以在不同的类别上完成，如品牌，型号名称，型号，颜色或价格等。
DONE:交易：在此模块中，购物车的管理已完成。此模块购物者可以选择任意数量的物品（手机，配件）并将它们添加到购物车，在从购物车购买物品后，所有要购买的物品都可以再次查看。如果他以后不喜欢，购物者也可以从购物车中取出。购物者还可以逐一检查购物车中保存的产品。由于产品从购物车中检出，总价格将相加。
DONE:装运：在这个模块中，购物者可以选择合适的装运选项。购物者可以使用不同服务提供商提供的各种运送选项。
DONE:付款：该模块描述了客户完成的付款。购物者可以选择不同的支付方式，并根据所选的支付方式的要求提供机密的支付信息。付款信息还可能包括购买型号，数量和供应商名称等信息。
DONE:报告：在此模块中，将生成所有报告。无论何时出售物品或客户订购产品，都应立即通过电子邮件向其供应商发送警报，以便他可以尽快装运该物品。该模块有3个子模块;股票报告，订单报告和交付报告。
股票报告将生成可用产品数量和产品状态的报告。
订单报告将列出订购的产品清单以及购买该产品的客户详细信息，这些信息未送达。
交付报告将生成已售出产品清单及其交付状态。
下面是以上功能的代码以及一些相关的解释：
最简单的主界面：
index.html
//只放了一个注册一个登录的链接
<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.注册功能：
首先要选择角色类型：（这个功能是刚开始练习做的，其实应该把角色选择和注册功能都放在一个页面里，现在分为了三个，分别是选择，管理员注册和用户注册，比较麻烦。后来时间紧，就没有再改了，实际可以合并为一个。）
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
//选择相应的角色后，会跳转到不同角色的注册界面
<!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）管理员注册：
adminSign.html
//管理员注册的界面。管理员注册需要拿到内部的Invitation number(邀请码)，注册方可进行。如果已经注册，可以点击下方的login链接，直接登录，将跳转到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
//处理管理员注册请求
<!DOCTYPE html><html><head>
<title>Sign in the phone web as admin user, success!</title></head><body>
<?php
include '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）用户注册
sign.html
//用户注册界面
<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
//处理用户注册请求，收集基本信息并加入到数据库。如果存在数据缺失，则不能注册，对两次输入的密码做了基本的检测，并检测邮箱格式的正确性。
//注册后会跳转到login.php界面，但是因为普通用户注册后，会自动为当前用户登录，并在当前的cookie中存储用户登录的状态，因此不需要再登录一次，可以直接由网页链接跳转到手机购买界面。

</html>10.搜索功能
做了一个分类搜索的功能，用的就是数据库的模糊查询，很简单
1）search.html
//页面
<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
//处理查询请求
<!DOCTYPE html>
<html>
<body><?php
if(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 connection
if (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><img src="data:image/jpeg;base64,'.$imageData.'"></td>'; echo "</tr>"; $i++;
} echo "</table>";
}
}?></body>
</html>特别说明：
1）购物车用session实现
2）其他各种用户登录状态，产品id等信息，均存储在cookie数组中
3）当某种产品卖出后，会从数据库中将该产品的库存减去订单中相应的数量。
11.数据库表设计
下面是对数据库设计的一个说明，交作业用的。
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.
另外需要说明的是，
delivery_info表和payment_info表中分别加入了一个random字段，是因为在写php处理的过程中，产生了相应的需要，具体处理请看代码。
下面是具体的表名和字段： 
12. 局限和反思
这个小项目做的时间非常赶，一共两周，实际有效时间只有10天，中间还在忙其他的事。所以有很多不足之处。
有些代码原本可以写的更精简，合并在一起。
连接数据库和其他的一些执行sql语句的操作，可以封装在单独的文件里面调用，这里也都比较简单的哪里用到就在哪里处理了。
数据库的链接方式用了两种，没有统一。
还是有很多值得改进的地方。
