As a lightweight open source blog system, Typecho is widely praised in the open source community for its simplicity and efficiency. Typecho is developed based on PHP and supports plug-in extensions, allowing developers to perform secondary development and customization according to their own needs. This article will share some cases of PHP development in Typecho and provide corresponding code examples, hoping to provide some reference for developers.

Case 1: Custom theme development

Typecho’s theme customization is very flexible, and you can customize it according to your own design concepts and needs. The following is a simple custom theme development case.

Step 1: Create a new theme folder and create the index.php file in the folder.

<?php if (!defined('__TYPECHO_ROOT_DIR__')) exit; ?>

<?php $this->need('header.php'); ?>

<div class="content">
    <?php while($this->next()): ?>
        <article class="post">
            <h2 class="title"><?php $this->title() ?></h2>
            <div class="content"><?php $this->content('阅读全文...'); ?></div>
        </article>
    <?php endwhile; ?>
</div>

<?php $this->need('footer.php'); ?>

Step 2: Create header.php and footer.php files to define the head and tail information of the website.

header.php sample code:

<!DOCTYPE html>
<html lang="zh-cn">
<head>
    <meta charset="<?php $this->options->charset(); ?>">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title><?php $this->archiveTitle(array(
            'category'  =>  _t('分类 %s 下的文章'),
            'search'    =>  _t('包含关键字 %s 的文章'),
            'tag'       =>  _t('标签 %s 下的文章'),
            'author'    =>  _t('%s 发布的文章')
        ), '', ' - '); ?><?php $this->options->title(); ?></title>
</head>
<body>

footer.php sample code:

<footer>
    <p>&copy; <?php echo date('Y'); ?> <?php $this->options->title(); ?>. All rights reserved.</p>
</footer>

</body>
</html>

Case 2: Plug-in development

Typecho’s plug-in mechanism is extremely convenient. You can develop various powerful plug-ins according to your own needs. The following is a simple plug-in development case, which is used to display the reading volume on the article page.

Step 1: Create a new plug-in folder and create the Plugin.php file in the folder.

<?php

class ReadCount_Plugin implements Typecho_Plugin_Interface
{
    public static function activate()
    {
        Typecho_Plugin::factory('Widget_Archive')->singleHandle = array('ReadCount_Plugin', 'handle');
    }

    public static function handle($archive)
    {
        if ($archive->is('single')) {
            $cid = $archive->cid;
            $db = Typecho_Db::get();
            $row = $db->fetchRow($db->select('views')->from('table.contents')->where('cid = ?', $cid));
            $views = empty($row['views']) ? 0 : $row['views'];
            $db->query($db->update('table.contents')->rows(array('views' => ($views + 1)))->where('cid = ?', $cid));
        }
    }

    public static function deactivate()
    {
    }

    public static function config(Typecho_Widget_Helper_Form $form)
    {
    }

    public static function personalConfig(Typecho_Widget_Helper_Form $form)
    {
    }

    public static function render()
    {
    }
}

Step 2: Place the plug-in folder in Typecho’s plug-in directory and enable the plug-in.

In the above case, we used Typecho's plug-in interface and added reading statistics logic to the article page processing function by rewriting the singleHandle method. When the article page is accessed, we count the number of readings by obtaining the cid of the article and then updating the views field in the database.

Through the above two cases, we can see that Typecho provides a rich PHP development interface and flexible extension mechanism, allowing developers to carry out secondary development and customization according to their own needs. I hope these cases can provide some help and inspiration for your PHP development in Typecho.
