基于php医院预约挂号系统
要实现一个基于PHP的医院预约挂号系统,你需要设计数据库、创建Web表单以及处理逻辑。以下是一个非常简单的例子,仅包含核心功能。
- 设计数据库:
CREATE TABLE `hospitals` (
`id` INT(11) NOT NULL AUTO_INCREMENT,
`name` VARCHAR(255) NOT NULL,
PRIMARY KEY (`id`)
);
CREATE TABLE `departments` (
`id` INT(11) NOT NULL AUTO_INCREMENT,
`hospital_id` INT(11) NOT NULL,
`name` VARCHAR(255) NOT NULL,
PRIMARY KEY (`id`),
FOREIGN KEY (`hospital_id`) REFERENCES `hospitals` (`id`)
);
CREATE TABLE `doctors` (
`id` INT(11) NOT NULL AUTO_INCREMENT,
`department_id` INT(11) NOT NULL,
`name` VARCHAR(255) NOT NULL,
PRIMARY KEY (`id`),
FOREIGN KEY (`department_id`) REFERENCES `departments` (`id`)
);
CREATE TABLE `appointments` (
`id` INT(11) NOT NULL AUTO_INCREMENT,
`doctor_id` INT(11) NOT NULL,
`date` DATE NOT NULL,
`time` TIME NOT NULL,
PRIMARY KEY (`id`),
FOREIGN KEY (`doctor_id`) REFERENCES `doctors` (`id`)
);
- 创建Web表单(HTML + PHP):
<?php
// 连接数据库...
// 获取输入
$doctorId = $_POST['doctor_id'];
$appointmentDate = $_POST['appointment_date'];
$appointmentTime = $_POST['appointment_time'];
// 插入数据库
$stmt = $pdo->prepare("INSERT INTO appointments (doctor_id, date, time) VALUES (?, ?, ?)");
$stmt->execute([$doctorId, $appointmentDate, $appointmentTime]);
echo "预约成功!";
?>
<form action="" method="post">
<label for="doctor_id">选择医生:</label>
<select name="doctor_id" id="doctor_id">
<!-- PHP代码生成医生列表 -->
</select>
<label for="appointment_date">选择日期:</label>
<input type="date" name="appointment_date" id="appointment_date">
<label for="appointment_time">选择时间:</label>
<input type="time" name="appointment_time" id="appointment_time">
<button type="submit">提交</button>
</form>
这个简单的例子展示了如何创建一个Web表单来接收用户的预约信息,并将这些信息保存到数据库中。在实际应用中,你需要为每个步骤添加更多的功能,例如身份验证、错误处理、日历集成等。
