How to use PHP and Typecho to build a book recommendation website

In the digital age, book recommendation websites have become one of the main ways for people to find new books. With the popularity of the Internet, more and more people are looking for book recommendation resources online, which provides huge opportunities and challenges for the development of book recommendation websites.

For beginners, using PHP and Typecho to build a book recommendation website is a good choice. As a simple and easy-to-use server-side scripting language, PHP can easily process web page data and interact with databases. Typecho is an open source blog engine based on PHP, providing powerful plug-ins and theme extension functions. The following will introduce how to use PHP and Typecho to build a simple book recommendation website.

First, we need to install and configure Typecho. You can download the latest version of Typecho source code from the official website (http://typecho.org) and extract it to the website root directory of the server. Then, complete the database configuration and site initialization according to the installation wizard provided by Typecho.

Next, we need to create a new Typecho theme. In the Typecho theme directory, create a folder named "book_recommend" and create a file named "index.php" under the folder. In index.php, we will use PHP to write the main logic code of the website.

First, we need to define some constants, such as the name and description of the website. The code example is as follows:

<?php
define('THEME_NAME', '图书推荐');
define('THEME_DESCRIPTION', '一个简单的图书推荐网站');
?>

Then, we need to introduce the core code of Typecho and instantiate the Typecho database object. The code example is as follows:

<?php
require_once 'path/to/Typecho/Widget.php';
require_once 'path/to/Typecho/Db.php';

$db = Typecho_Db::get();
?>

Next, we can start writing the main functions of the book recommendation website. First, we need to get the book information from the database and display it on the website. The code example is as follows:

<?php
$books = $db->fetchAll($db->select()->from('table.books')->order('publish_time DESC'));
foreach ($books as $book) {
    echo '<div class="book">';
    echo '<h2>'.$book['title'].'</h2>';
    echo '<p>'.$book['author'].'</p>';
    echo '<p>'.$book['description'].'</p>';
    echo '</div>';
}
?>

In the above code, we use Typecho's database query method to obtain book information from the data table named "books" and sort it in descending order by publication time. Next, we use a loop structure to display information such as the title, author, and description of each book on the web page.

Next, we can add some styles to beautify the website. Create a file called "style.css" in the "book_recommend" theme directory and add some CSS styles in it. The code example is as follows:

.book {
    border: 1px solid #ccc;
    padding: 10px;
    margin-bottom: 10px;
}

.book h2 {
    font-size: 20px;
    color: #333;
}

.book p {
    font-size: 14px;
    color: #666;
}

In the above code, we have added some borders, padding, spacing and other styles to the book block of the book recommendation website. At the same time, we've adjusted the font size and color of book titles and descriptions.

Finally, we need to enable the "book_recommend" theme in Typecho's control panel. In Typecho's background management interface, select "Appearance" -> "Set Appearance" and select "book_recommend" as the current theme. We can then visit the website and see how the book recommendations perform.

Through the above steps, we successfully built a simple book recommendation website using PHP and Typecho. Of course, this is just an entry-level example, and you can further improve and expand this website according to your own needs. I hope this article can provide some help and guidance for beginners to start building a book recommendation website. I wish you success!
