How to use PHP to implement a simple online submission and review system

Introduction:
With the development of the Internet, more and more people are beginning to use the Internet Carry out various activities. In the academic field, the submission and review of academic papers is a very important part. This article will introduce how to use PHP to implement a simple online submission and review system, providing a convenient and fast submission and review method for the academic community.

1. System requirements analysis
Before starting implementation, we first need to clarify the system requirements.

1. User registration and login: Users need to register an account first, and then use this account to log in to the system.
2. Submission function: After logging in to the system, users can submit their own academic papers.
3. Audit function: After logging in to the system, the administrator can review papers submitted by users and give review opinions.
4. Paper management function: Both users and administrators can view their own submission and review records.
5. User rights management: Administrators can manage user roles and rights.

2. System design and implementation

1. Database design
   First, we need to design the database, including the following tables:

• User table (users): stores user login information, including user name, password, role, etc.
• Papers table (papers): stores basic information of papers, such as title, author, abstract, etc.
• Review table (reviews): stores the review information of the paper, including review opinions, review results, etc.

2. User registration and login function
   User registration and login function are the basic functions of the system. We can use MySQL to store user information.

First, create a user registration page (register.php), including input boxes for username and password, and a registration button. After the user fills in the information, click the registration button to send the information to the background for processing.

Backend code example (register.php):

<?php
  // 获取用户提交的注册信息
  $username = $_POST['username'];
  $password = $_POST['password'];

  // 将用户信息插入数据库
  $sql = "INSERT INTO users (username, password) VALUES ('$username', '$password')";
  // 执行插入操作

  // 注册成功，跳转到登录页面
  header('Location: login.php');
?>

Create a user login page (login.php), including input boxes for username and password, and a login button. After the user fills in the information, click the login button to send the information to the background for processing.

Backend code example (login.php):

<?php
  // 获取用户提交的登录信息
  $username = $_POST['username'];
  $password = $_POST['password'];

  // 检查用户名和密码是否匹配数据库中的记录
  $sql = "SELECT * FROM users WHERE username='$username' AND password='$password'";
  // 执行查询操作

  // 登录成功，将用户信息保存到session中
  session_start();
  $_SESSION['username'] = $username;

  // 跳转到投稿页面
  header('Location: submit_paper.php');
?>

3. Submission function
   After successful login, the user can enter the submission page (submit_paper.php) and fill in the basic information of the paper , and click the submit button to send the information to the background for processing.

Backend code example (submit_paper.php):

<?php
  // 获取用户提交的论文信息
  $title = $_POST['title'];
  $author = $_POST['author'];
  $abstract = $_POST['abstract'];

  // 将论文信息插入数据库
  $sql = "INSERT INTO papers (title, author, abstract) VALUES ('$title', '$author', '$abstract')";
  // 执行插入操作

  // 提交成功，跳转到论文管理页面
  header('Location: paper_management.php');
?>

4. Audit function
   After the administrator successfully logs in, he can enter the review page (review_papers.php) to view List of papers to be reviewed and review the papers.

Backend code example (review_papers.php):

<?php
  // 查询待审核的论文列表
  $sql = "SELECT * FROM papers WHERE status='待审核'";
  // 执行查询操作

  // 显示待审核的论文列表
  while ($row = $result->fetch_assoc()) {
    echo $row['title'];
    echo $row['author'];
    echo $row['abstract'];

    // 添加审核按钮
    echo "<button onclick='reviewPaper(" . $row['id'] . ")'>审核</button>";
  }
?>

The specific operation of the review can send the review results to the background for processing through AJAX requests.

5. Paper management function
   Both users and administrators can enter the paper management page (paper_management.php) to view their submission and review records.

Backend code example (paper_management.php):

<?php
  // 获取当前用户的用户名
  session_start();
  $username = $_SESSION['username'];

  // 查询当前用户的投稿和审核记录
  $sql = "SELECT * FROM papers WHERE author='$username' OR reviewer='$username'";
  // 执行查询操作

  // 显示投稿和审核记录
  while ($row = $result->fetch_assoc()) {
    echo $row['title'];
    echo $row['author'];
    echo $row['abstract'];
  }
?>

3. User rights management
In actual applications, there may be users with multiple roles, such as authors, Editors, reviewers, etc. We can implement permission management for different roles by adding a role field (role) to the user table.

When a user registers, he or she needs to select a role and save the role information to the database. Users with different roles can access different pages and functions.

4. Summary
This article introduces how to use PHP to implement a simple online submission and review system. Through the realization of functions such as registration, login, submission, review and paper management, it provides a convenient and fast method for submission and review of papers for the academic community. Readers can further improve the system's functions and interface according to their actual needs, and improve the system's usability and user experience.
