The second-hand recycling website developed by PHP provides the background review function of product release
As people pay more and more attention to sustainable development and environmental protection, second-hand recycling is gradually becoming a popular consumer trend. In order to meet users' trading needs for second-hand items, many second-hand recycling websites have emerged. This article will introduce a second-hand recycling website developed based on PHP, which provides a background review function for posted goods to ensure the safety and accuracy of transactions.
First, we need to create a database table to store product information published by users. The following is a simple MySQL table structure example:
CREATE TABLE `goods` ( `id` int(11) NOT NULL AUTO_INCREMENT, `user_id` int(11) NOT NULL, `title` varchar(255) NOT NULL, `description` text, `price` decimal(10,2) NOT NULL, `status` enum('pending','approved','rejected') NOT NULL DEFAULT 'pending', PRIMARY KEY (`id`) );
The above table structure includes the product ID, user ID, title, description, price and status. The status field is used to mark the review status of the product, including pending review, approved, and rejected.
Next, we need to create a backend management page to review and manage the products posted by users. The following is a simplified sample code:
<?php // 连接数据库 $servername = "localhost"; $username = "username"; $password = "password"; $dbname = "database"; $conn = new mysqli($servername, $username, $password, $dbname); if ($conn->connect_error) { die("连接失败: " . $conn->connect_error); } // 获取待审查商品列表 $sql = "SELECT * FROM goods WHERE status = 'pending'"; $result = $conn->query($sql); if ($result->num_rows > 0) { while($row = $result->fetch_assoc()) { echo "商品标题: " . $row["title"]. " - 价格: " . $row["price"]. "<br>"; echo "描述: " . $row["description"]. "<br>"; echo "<button onclick='approveProduct(" . $row["id"]. ")'>批准</button>"; echo "<button onclick='rejectProduct(" . $row["id"]. ")'>拒绝</button>"; echo "<hr>"; } } else { echo "暂无待审查商品"; } // 批准商品 function approveProduct($productId) { // 更新商品状态为已批准 $sql = "UPDATE goods SET status = 'approved' WHERE id = $productId"; if ($conn->query($sql) === TRUE) { echo "商品已批准"; } else { echo "更新商品状态失败: " . $conn->error; } } // 拒绝商品 function rejectProduct($productId) { // 更新商品状态为已拒绝 $sql = "UPDATE goods SET status = 'rejected' WHERE id = $productId"; if ($conn->query($sql) === TRUE) { echo "商品已拒绝"; } else { echo "更新商品状态失败: " . $conn->error; } } $conn->close(); ?>
The above code demonstrates how to obtain a list of items to be reviewed from the database and provides the functionality to approve and reject items. By clicking the corresponding button, the item status in the database can be updated.
The product information submitted by the user will be stored in the database and reviewed in the background management page. Administrators may approve or reject an item based on its accuracy, completeness, and legality.
By implementing this background review function for product release, second-hand recycling websites can ensure the safety and accuracy of transactions. At the same time, administrators can also manage and handle illegal products to improve the user experience.
To sum up, the second-hand recycling website developed by PHP provides a background review function for product release, which can ensure the safety and accuracy of transactions. Through the reasonable use of database and backend management page technology, the review and management of products released by users are realized. This function will effectively improve the credibility and user satisfaction of the website and promote the prosperity of second-hand transactions.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
