How to use PHP to implement the friendly link function of the CMS system

With the development of the Internet, friendly links are a common means of website mutual promotion in the CMS system Plays a very important role. Through the friendly link function, websites can promote each other and increase off-site traffic and brand exposure. This article will introduce how to use PHP to implement the friendly link function in the CMS system for better website promotion and cooperation.

1. Database design

The friendly link function usually requires the use of a database to store link-related information. First we need to create a database table to store friendly link information, including link name, link address, link description and other fields. The following is an example database table design:

CREATE TABLE links (
id int(11) NOT NULL AUTO_INCREMENT,
name varchar(255) NOT NULL,
url varchar(255) NOT NULL,
description text NOT NULL,
created_at timestamp NOT NULL DEFAULT current_timestamp(),
updated_at timestamp NOT NULL DEFAULT current_timestamp() ON UPDATE current_timestamp(),
PRIMARY KEY (id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

2. Add link page

In the CMS system, there is usually a background management page to manage friendly links. We can add a form for adding links on this page, in which users can fill in information such as the name, address, and description of the link. The following is a sample add link page code:

Link name



Link address label>



Link description> ;

3. Add link processing

Next, we need to write a PHP file for processing add link requests. In this file, we can obtain the link information filled in the form and save it to the database. The following is an example of add link processing code (add_link.php):

// Connect to the database
$host = "localhost";
$dbname = "your_database_name ";
$username = "your_username";
$password = "your_password";
$conn = new PDO("mysql:host=$host;dbname=$dbname", $username, $password );

// Get form data
$name = $_POST['name'];
$url = $_POST['url'];
$description = $_POST[ 'description'];

// Insert data into the database
$stmt = $conn->prepare("INSERT INTO links (name, url, description) VALUES (:name, :url, :description)");
$stmt->bindParam(':name', $name);
$stmt->bindParam(':url', $url);
$stmt- >bindParam(':description', $description);
$stmt->execute();

// Prompt that the addition was successful
echo "The link has been added successfully!";
?>

4. Display link page

In the CMS system, there is usually a page for displaying friendly links. This page will query the link information from the database and displayed on the page. The following is an example display link page code:

//Connect to the database
$host = "localhost";
$dbname = "your_database_name";
$username = "your_username";
$password = "your_password";
$conn = new PDO("mysql:host=$host;dbname=$dbname", $username, $password);

// Query link information
$stmt = $conn->prepare("SELECT * FROM links");
$stmt->execute();
$links = $stmt- >fetchAll(PDO::FETCH_ASSOC);

// Display link
foreach ($links as $link) {
echo "" . $link['name'] . " - " . $link['description'] . "
";
}
?>

Through the above code, we can implement a simple friend link function. Users can add links on the background management page and then display these links on the display link page. The code can be modified and optimized according to actual needs, and more functions can be added, such as editing and deleting friendly links.

Summarize

This article introduces how to use PHP to implement the friendly link function in the CMS system. Through the design and operation of the database, we can easily manage and display the friendly links. The function of friendly links can increase the influence and exposure of the website, and provides convenience for website cooperation and promotion. It is one of the very important functions. I hope this article will be helpful for you to add the friendly link function when developing a CMS system.
