Preface
During the website maintenance process, I faced an important challenge: migrating the CTA (action call) configuration from Ad INSERTER to WPCode, and implementing more flexible priority judgments. This article will introduce this migration process and implementation method in detail.
Problem found
After migrating the website from Hueman theme to WordPress 2025 theme, I found that the articles under some series no longer show the corresponding CTA description (Figure 1). This made me realize that the CTA display mechanism needs to be reconfigured.
problem analysis
After analysis, I found that AD INSERTER has a compatibility problem in the new topic. So I decided to migrate the CTA configuration to WPCode, and can achieve a more flexible priority judgment (Figure 2).
Solution Exploration: Series Category Solutions
Initially, I thought about implementing CTA configuration based on series categories. The advantages of this scheme are:
- Clear hierarchy: Series categories can better organize and manage multiple series
- strong extensibility: New series can be easily added to existing categories
- Logic and intuitive: The relationship between the series can be better understood through the parent relationship
However, during the implementation, I found some challenges with this scheme:
- Series Categories are complex: Need to make sure that each series is properly assigned to the corresponding category
- Difficult to debug: In WordPress, the hierarchy relationship of series categories is sometimes not intuitive enough
- Time limit: Due to the tight project time, this scheme cannot be fully realized and tested
Ultimately, due to time constraints, I decided to temporarily give up the series-based scheme and use the more direct-based implementation of the series-based slug.
Final Scheme: Migrate to WPCode with Priority Implementation
Step 1: Add ShortCode in the theme editor
First, I’m in the theme editor, a single article – template, add shortcode block after content block, then paste wpcode
(Figure 3).
Step 2: Try Auto Insert
However, this method is not valid. So, I try to use Auto Insert, the location selects ‘insert after content’ (Figure 4).
Step 3: Adjust the Auto Insert settings
After it doesn’t work again, I decided to use Auto Insert, the location selects ‘frontend only’ and determines the insertion position in the code (Figure 5).
Step 4: Successful Implementation
In the end, this method succeeded! The articles under a series will be displayed based on the descriptions under this series (Figure 6).
code implementation
The following is the complete code implementation, which includes the priority judgment logic:
PHP
// ==========================================
// 使用 WordPress 原生钩子，强制在内容后插入
// ==========================================
add_filter('the_content', 'custom_desc_and_ads_inserter', 20);
function custom_desc_and_ads_inserter($content) {
// 1. 仅在单篇文章页面执行，排除后台、Feed、首页等
if (!is_singular('post') || is_admin() || is_feed()) {
return $content;
}
// 2. 安全获取文章ID
$post_id = get_the_ID();
if (!$post_id) {
global $wp_query;
if (isset($wp_query->queried_object_id)) {
$post_id = $wp_query->queried_object_id;
}
}
// 3. 初始化变量
$current_lang = '';
$current_series_slugs = array();
if (class_exists('SitePress')) {
$current_lang = apply_filters('wpml_current_language', null);
}
if (empty($current_lang)) {
$current_lang = (false !== strpos($_SERVER['REQUEST_URI'], '/en/')) ? 'en' : 'zh';
}
if ($post_id) {
$current_series = get_the_terms($post_id, 'series');
if (is_array($current_series) && !is_wp_error($current_series)) {
$current_series_slugs = wp_list_pluck($current_series, 'slug');
}
}
$output_html = '';
// ==========================================
// 4. 优先级判断逻辑 (保持不变)
// ==========================================
if ($current_lang === 'zh' && in_array('self-hosted-vpn', $current_series_slugs)) {

}
Priority Implementation: Classification Tree Functional Testing
I also tested demo1_custom_in_category_tree(linux) function. It is found that a certain article does not belong to the classification Linux, but only belongs to the Sun classification Ubuntu 26.04 (Figure 7).
Priority Validation: Expected Results
Even if the article belongs only to the Sun classification, it will still display CUSTOM_IN_CATEGORY_TREE(linux) The description, which is in line with our priorities expectation (Figure 8).
Conclusion
With this migration, I successfully migrated the CTA configuration from the AD INSERTER to WPCode and implemented a more flexible priority judgment. Although initially considered a series-based scheme, due to time constraints, the priority implementation based on the series Slug was finally selected. The new solution not only solves the problem of the series description display after the theme switching, but also provides a more powerful classification tree function.
Hope this article is helpful for developers who are considering similar migrations!
