Implementation method of delivery time selection function of food shopping system developed in PHP

How to implement the delivery time selection function of PHP development of grocery shopping system

With the improvement of people's living standards and changes in consumption concepts, more and more people are beginning to Choose to buy fresh ingredients online instead of going to the traditional market. Therefore, it is very important to develop a set of functions that facilitate users to choose delivery time. This article will introduce how to use PHP to implement the delivery time selection function of a grocery shopping system.

1. Requirements Analysis

Before development, we first need to clarify the functional requirements so that subsequent development work can be carried out in a targeted manner. In the grocery shopping system, users need to be able to choose the appropriate delivery time according to their own needs. Generally speaking, the delivery time selection function of the grocery shopping system should have the following functions:

  1. Provide multiple time periods for users to choose, such as morning, noon, afternoon, evening, etc.
  2. Dynamic display of selectable delivery dates based on the time period selected by the user.
  3. Users can select a specific delivery date by clicking on the date.
  4. Users can reserve multiple different delivery dates and times.

2. Database design

In order to store the delivery time and date selected by the user, we need to design a database table to store this information. Assume that our database is named delivery_time and the table is named delivery_slots. This table can be created through the following SQL statement: 

CREATE TABLE `delivery_slots` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `slot` varchar(50) NOT NULL,
  `date` date NOT NULL,
  PRIMARY KEY (`id`)
);

In this table, ## The #slot column is used to store the time period, and the date column is used to store the specific date.

3. Page design and implementation

In terms of page design and implementation, we can use HTML and PHP to complete it. First, we need to create a page to display the delivery time selection function. The following is a simple example: 

<!DOCTYPE html>
<html>
<head>
    <title>买菜系统 - 配送时间选择</title>
</head>
<body>
    <h1>请选择配送时间</h1>
    <form action="submit.php" method="post">
        <label for="slot">时间段：</label>
        <select name="slot" id="slot">
            <option value="morning">早上</option>
            <option value="noon">中午</option>
            <option value="afternoon">下午</option>
            <option value="evening">晚上</option>
        </select>
        <label for="date">日期：</label>
        <input type="date" name="date" id="date">
        <input type="submit" value="预约">
    </form>
</body>
</html>

In this page, we use a

element to package each form item for delivery time selection. Users can select a time period through the drop-down menu, select a specific date through the date selector, and complete the delivery time selection by clicking the submit button. 4. Background data processing

Next, we need to create a

submit.php file to process the delivery time selected by the user on the front page and insert the data into in the database. 

<?php
// 连接数据库
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "delivery_time";

$conn = new mysqli($servername, $username, $password, $dbname);

// 处理用户选择的配送时间
$slot = $_POST['slot'];
$date = $_POST['date'];

// 将数据插入数据库
$sql = "INSERT INTO delivery_slots (slot, date) VALUES ('$slot', '$date')";
$result = $conn->query($sql);

// 提示用户预约成功
if ($result) {
    echo "预约成功！";
} else {
    echo "预约失败，请稍后再试。";
}

// 关闭数据库连接
$conn->close();
?>

In this file, we first establish a database connection and obtain the delivery time selected by the user on the front page. Then, use the

INSERT INTO statement to insert this data into the delivery_slots table of the database. Finally, corresponding prompts are provided based on the insertion results.

5. Summary and Outlook

Through the above steps, we have successfully implemented the delivery time selection function of a grocery shopping system. Users can select the appropriate delivery time according to their needs and save the selection results in the database. Of course, this is just a basic implementation method, and various improvements and optimizations can be made according to the actual situation, such as adding processing of time conflicts, limiting delivery time, etc.

I hope this article can bring you some help in implementing the delivery time selection function of the PHP grocery shopping system. I also hope it can stimulate your creativity and further improve and perfect this function. Good luck with your development!
