Case Study of Shopping Mall Logistics Interface Code: PHP technology realizes timeliness query function!

With the rapid development of the Internet and the vigorous development of the e-commerce industry, the logistics field has also been greatly improved. For shopping malls, logistics is an indispensable part, and being able to provide customers with accurate and timely query functions is an important part of enhancing customer experience. This article will take a shopping mall logistics interface code case study as an example to introduce how to use PHP technology to implement time-sensitive query functions, and provide relevant code examples.

1. Demand analysis

When designing the logistics interface, we need to meet the following requirements:

Query timeliness: Customers can query logistics based on the order number Arrival Time to find out the current status and estimated arrival time of your order.
Automatic update: Logistics information needs to be updated in time to ensure the accuracy and real-time nature of query results.
Friendly user interface: The user query interface should be simple, intuitive, easy to operate, and meet the needs of ordinary users.

2. System design

Based on the above requirements, we can design a simple logistics query system, including the following parts:

Database design : Create a logistics information table to store fields such as order number, logistics status, arrival time, etc.
Back-end code: Use PHP to write back-end code, which is responsible for processing user query requests, querying the database and returning query results.
Front-end interface: Use HTML and CSS to write the front-end interface to provide a user-friendly query interface.

3. Code Implementation

The following is a simplified sample code that shows how to use PHP technology to implement time-sensitive query functions:

Database Design

First, we need to create a logistics information table named "orders", containing the following fields:

CREATE TABLE orders (
  id INT PRIMARY KEY AUTO_INCREMENT,
  order_number VARCHAR(50),
  status VARCHAR(50),
  estimated_arrival DATE
);

Backend code

In the PHP code, we can obtain logistics information by querying the order number and return the query results. The following is a simple sample code:

<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$order_number = $_POST['order_number'];

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

if ($conn->connect_error) {
  die("Connection failed: " . $conn->connect_error);
}

$sql = "SELECT * FROM orders WHERE order_number = '$order_number'";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
  while($row = $result->fetch_assoc()) {
    echo "Order Number: " . $row["order_number"]. "<br>";
    echo "Status: " . $row["status"]. "<br>";
    echo "Estimated Arrival: " . $row["estimated_arrival"]. "<br>";
  }
} else {
  echo "No results found";
}
$conn->close();
?>

Front-end interface

In the HTML code, we can create a simple form that allows the user to enter an order number and submit a query ask. The following is a sample code:

<!DOCTYPE html>
<html>
<head>
  <title>Logistics Tracking</title>
</head>
<body>
  <h1>Logistics Tracking</h1>
  <form action="query.php" method="POST">
    <label for="order_number">Order Number:</label>
    <input type="text" id="order_number" name="order_number">
    <input type="submit" value="Search">
  </form>
</body>
</html>

4. Summary

Through the above code implementation, we can implement a simple timeliness query function. When the user enters the order number and submits a query request, the back-end PHP code will query the database and return the query results, and the front-end interface will display the logistics information. In this way, shopping malls can provide customers with accurate timeliness query functions and improve user experience.

It should be noted that the above example code is just a simplified case, and issues such as security and performance optimization may also need to be considered in actual applications. At the same time, according to specific business needs and requirements, we can also expand the functions of the logistics interface, such as adding the function of sending logistics notifications, etc.

In short, PHP technology can well realize the time-sensitive query function of the shopping mall logistics interface. Through reasonable system design and code implementation, we can provide a convenient query system to enhance the user experience and enhance the competitiveness of the shopping mall. .
