Sharing of PHP development practices in Typecho

Introduction:
Typecho is a lightweight open source blog system. Due to its simplicity, speed, security and other advantages, it is increasingly loved by developers. . This article will share some PHP practical experience in Typecho development, and attach relevant code examples, hoping to bring some help and inspiration to Typecho developers.

1. Using Typecho built-in functions
   Typecho provides many built-in functions that can easily obtain blog configuration information, article metadata, etc. For example, use Typecho_Widget::widget('Widget_Archive') to get the information of the current article, and use Typecho_Widget::widget('Widget_Options')->themeUrl to get the current theme URL. You can use these functions in your theme template files to easily obtain the data you need.

Code example:

<?php $options = Typecho_Widget::widget('Widget_Options'); ?>
<img src="<?php $options->themeUrl('images/logo.png'); ?>" alt="Logo">

2. Customized independent page
   Typecho allows users to create independent pages, which can be used to display personal profiles, friendly links and other content. You can create an independent page template in the theme directory and select the corresponding template when creating a new page in the background. Then, add customized HTML code to the page template file to achieve personalized page display effects.

Code sample:

<?php if ($this->fields->cover): ?>
    <img src="<?php echo $this->fields->cover; ?>" alt="Cover">
<?php endif; ?>
<h2><?php $this->title(); ?></h2>
<p><?php $this->content(); ?></p>

3. Database operation
   In Typecho development, we often need to interact with the database and manipulate data. Typecho encapsulates a series of database operation functions, which can easily perform operations such as insertion, update, and deletion. When developing plug-ins or themes, you can use these functions to implement customized functions.

Code sample:

<?php $db = Typecho_Db::get();
$prefix = $db->getPrefix();
$users = $db->fetchAll('SELECT * FROM ' . $prefix . 'users');
foreach ($users as $user) {
    echo $user['name'];
}

4. Verify user identity
   Typecho provides a simple and powerful authentication mechanism that can be used to protect certain areas that require login before accessing page. Get the information of the currently logged in user by using the Typecho_Widget::widget('Widget_User') function and determine whether the user has specific permissions.

Code sample:

<?php if ($this->user->hasLogin()): ?>
    <p>Welcome, <?php $this->user->screenName(); ?></p>
<?php else: ?>
    <p>Please login first.</p>
<?php endif; ?>

Conclusion:
In the development process of Typecho, rational use of built-in functions, customized independent pages, database operations, authentication and other functions can greatly Improve development efficiency and user experience. I hope the practical experience shared in this article can be helpful to Typecho developers.

This article is only a preliminary introduction. There are many Typecho development techniques and practices worth exploring and sharing. I hope developers can continue to study and research in depth. I hope Typecho’s development ecosystem will continue to grow and provide users with more rich and personalized functions.
