Implementing online medical appointment system using WebMan technology

Using WebMan technology to implement online medical appointment system

With the continuous development and popularization of network technology, all walks of life are actively using the Internet to provide more convenient and Efficient service. The medical industry is no exception. More and more hospitals are beginning to realize that online medical appointment systems can provide patients with a better medical experience. This article will introduce how to use WebMan technology to implement a simple online medical appointment system.

WebMan is a Web application development tool based on PHP and MySQL. It provides a series of functions and tools that make it easier for developers to build web applications. In this project, we will use WebMan to build the front-end interface of the system and store the data in a MySQL database.

First, we need to create a database to store the patient's appointment information. We can use MySQL's command line tools or graphical management tools to create databases and tables. The following is a simple SQL creation statement:

CREATE DATABASE medical_appointment;
USE medical_appointment;

CREATE TABLE appointments (
  id INT AUTO_INCREMENT PRIMARY KEY,
  name VARCHAR(50) NOT NULL,
  phone VARCHAR(15) NOT NULL,
  appointment_date DATE NOT NULL,
  time_slot TIME NOT NULL
);

Next, we need to create a WebMan application. We can place the source code of WebMan in the Web root directory of the server and create an application named "appointment". The following is the directory structure of the application:

/webroot
   ├── appointment
   │   ├── resources
   │   └── templates
   └── webman

Copy after login

In the "resources" directory, we can create a file named "index.php" as the entry point of the system.

<?php
require_once '../webman/Loader.php';
require_once '../webman/WebApp.php';

class MyApp extends WebApp {
    public function onRequest($request, $response) {
        $response->setBody($this->render('index.tpl'));
    }

    public function onSubmit($request, $response) {
        // 处理预约提交逻辑
        // ...
        $response->redirect('/');
    }
}

WebMan::instance()->init(new MyApp())->run();

Copy after login

The above code defines an application class named "MyApp" and implements the "onRequest" and "onSubmit" methods. The "onRequest" method will render the template file named "index.tpl" and set the result to the content of the response. The "onSubmit" method will handle the logic of appointment submission and redirect to the home page.

In the "templates" directory, we can create a template file named "index.tpl" to define the front-end interface of the system.

<!DOCTYPE html>
<html>
<head>
    <title>医疗预约系统</title>
</head>
<body>
    <h1>医疗预约系统</h1>
    <form action="/submit" method="POST">
        <label for="name">姓名：</label>
        <input type="text" id="name" name="name" required><br>

        <label for="phone">手机号码：</label>
        <input type="text" id="phone" name="phone" required><br>

        <label for="date">预约日期：</label>
        <input type="date" id="date" name="appointment_date" required><br>

        <label for="time">时间段：</label>
        <select id="time" name="time_slot" required>
            <option value="上午">上午</option>
            <option value="下午">下午</option>
            <option value="晚上">晚上</option>
        </select>

        <button type="submit">提交</button>
    </form>
</body>
</html>

Copy after login

The above code defines an HTML page containing form elements. Users submit reservation information by filling out a form. The "action" attribute of the form specifies the URL for data submission, and the method is POST. By setting the "required" attribute of the form element, we ensure that the user must fill in all fields. Once the user clicks the submit button, the form data will be sent to the server.

When submitting data, we can handle the logic of reservation submission in the "onSubmit" method. For example, we can verify that the mobile phone number is legitimate and save the data to the database.

Implementing a complete online medical appointment system requires more functions, such as displaying existing appointment lists, administrator login, etc. However, only the most basic scheduling features are covered in this article. I hope readers can master the basic process of building Web applications using WebMan technology through this article.

Through WebMan technology, we can quickly build a simple online medical appointment system. Using the powerful functions of PHP and MySQL, we can implement more and more complex functions. In the future, with the advancement and development of technology, we believe that online medical appointment systems will play an increasingly important role in the medical industry.
