How to add custom metafields to custom classification in WordPress
Apr 18, 2025 am 11:11 AMDo you need to add custom metafields to custom taxonomy in WordPress?
Custom taxonomy allows you to organize content besides categories and tags. Sometimes it is useful to add other fields to describe them.
In this article, we will show you how to add other metafields to the taxonomy they create.
When should custom metafields be added to custom taxonomy?
When you create new content on your WordPress site, you can organize it using two default taxonomy (category and tag).
Some websites benefit from the use of custom taxonomy. These allow you to sort content in other ways.
For example, websites that publish book reviews can add "topic" and "author" taxonomy so that visitors can quickly find comments they are interested in.
For more information, see a guide on how to create a custom taxonomy in WordPress.
By default, each taxonomy has only three to four fields: name, slug, parent (if hierarchical), and description.
Sometimes it is useful to add other fields to better describe the taxonomy. For example, you can add the Year of Birth field to the Authors taxonomy.
That being said, here is how to add custom metafields to custom taxonomy in WordPress.
Adding custom metafields to custom classification in WordPress
First, you need to install and activate the Advanced Custom Fields Plugin. To learn more, see our step-by-step guide on how to install WordPress plug-ins.
Next, go to Custom Fields ?Add New Page. Here you can add a field group that contains one or more new fields.
You will be asked to assign a title to the field group that will be displayed with the new field when you add or edit a taxonomy. In this tutorial, we want to add custom fields to the author category, so we name the field group "Author Details".
Once you have done this, you should click the Add Field button to add the field. A new form will appear where you can fill in the details of the new field.
After entering the field tag, the system will automatically create a field name for you, which you can edit as needed. You will need to use the field name later in this tutorial, so note it down.
You should now fill in additional details for the field, such as field type, description of the author who will fill out the form, and whether the field is required. Other options not shown in the screenshot include default text, placeholder text, character limits, and more.
If you want to add a second field, you should click the Add Field button and repeat the process. Otherwise, just scroll down to the Position section.
Here you can create rules that describe where the new field is displayed. You should select "Taxonomy" from the first drop-down menu and leave the intermediate field as "Equal to". Finally, select the correct custom taxonomy for the last field. In this tutorial, we will select "Author".
If you want to add this field to another taxonomy, you can click the Add Rule Group button and repeat the step.
Now you should adjust any other settings on the page. We just need to keep the default value. Once you're done, you should scroll to the top of the page and click the Publish button.
Congratulations, you have successfully added a custom metafield to your custom taxonomy in WordPress. But you have more work to do.
Add data to new custom metafields
Although the taxonomy has a new field, it does not contain any data yet. You should take some time to do this now.
In our example, we need to enter the birth year of each author. To do this, we need to navigate to Post ? Author and click on the author name we want to edit.
After that, we can enter the data in the new field. In this case, we will enter the author's year of birth. Don't forget to click the "Update" button to store new data.
You should follow the same steps on the website to add the data to your custom taxonomy.
Once you're done, there's one more step to do. Although you can see a custom field when you log in to the WordPress admin area, visitors to your website will not be able to see it. You need to add this field to the archive page of the custom category.
Show custom metafields on category archive page
In this step, you need to add the code to the theme file. If you haven't done this before, see our beginner's guide on how to paste web clips into WordPress.
The first thing you need to do is go into the topic folder and look for the classified archive file. It will have a similar name taxonomy-YOURTAXONOMYNAME.php.
For example, if you have a custom taxonomy called "Author", then you need to look for a taxonomy-authors.php.
If you don't see the file, look for archive.php. You need to copy the file and name it as above.
Note : If your theme does not contain archive.php, you may be using the WordPress theme framework and you must create a classification archive manually. A great starting point for learning how to create archive files is our guide on how to create custom archive pages in WordPress.
Now you need to add the following code to the classification archive before the loop:

The main reasons why WordPress causes the surge in server CPU usage include plug-in problems, inefficient database query, poor quality of theme code, or surge in traffic. 1. First, confirm whether it is a high load caused by WordPress through top, htop or control panel tools; 2. Enter troubleshooting mode to gradually enable plug-ins to troubleshoot performance bottlenecks, use QueryMonitor to analyze the plug-in execution and delete or replace inefficient plug-ins; 3. Install cache plug-ins, clean up redundant data, analyze slow query logs to optimize the database; 4. Check whether the topic has problems such as overloading content, complex queries, or lack of caching mechanisms. It is recommended to use standard topic tests to compare and optimize the code logic. Follow the above steps to check and solve the location and solve the problem one by one.

Methods to optimize WordPress sites that do not rely on plug-ins include: 1. Use lightweight themes, such as Astra or GeneratePress, to avoid pile-up themes; 2. Manually compress and merge CSS and JS files to reduce HTTP requests; 3. Optimize images before uploading, use WebP format and control file size; 4. Configure.htaccess to enable browser cache, and connect to CDN to improve static resource loading speed; 5. Limit article revisions and regularly clean database redundant data.

Miniving JavaScript files can improve WordPress website loading speed by removing blanks, comments, and useless code. 1. Use cache plug-ins that support merge compression, such as W3TotalCache, enable and select compression mode in the "Minify" option; 2. Use a dedicated compression plug-in such as FastVelocityMinify to provide more granular control; 3. Manually compress JS files and upload them through FTP, suitable for users familiar with development tools. Note that some themes or plug-in scripts may conflict with the compression function, and you need to thoroughly test the website functions after activation.

TransientsAPI is a built-in tool in WordPress for temporarily storing automatic expiration data. Its core functions are set_transient, get_transient and delete_transient. Compared with OptionsAPI, transients supports setting time of survival (TTL), which is suitable for scenarios such as cache API request results and complex computing data. When using it, you need to pay attention to the uniqueness of key naming and namespace, cache "lazy deletion" mechanism, and the issue that may not last in the object cache environment. Typical application scenarios include reducing external request frequency, controlling code execution rhythm, and improving page loading performance.

Object cache assists persistent storage, suitable for high access and low updates, tolerating short-term lost data. 1. Data suitable for "persistence" in cache includes user configuration, popular product information, etc., which can be restored from the database but can be accelerated by using cache. 2. Select a cache backend that supports persistence such as Redis, enable RDB or AOF mode, and configure a reasonable expiration policy, but it cannot replace the main database. 3. Set long TTL or never expired keys, adopt clear key name structure such as user:1001:profile, and update the cache synchronously when modifying data. 4. It can combine local and distributed caches to store small data locally and big data Redis to store big data and use it for recovery after restart, while paying attention to consistency and resource usage issues.

When developing Gutenberg blocks, the correct method of enqueue assets includes: 1. Use register_block_type to specify the paths of editor_script, editor_style and style; 2. Register resources through wp_register_script and wp_register_style in functions.php or plug-in, and set the correct dependencies and versions; 3. Configure the build tool to output the appropriate module format and ensure that the path is consistent; 4. Control the loading logic of the front-end style through add_theme_support or enqueue_block_assets to ensure that the loading logic of the front-end style is ensured.

PluginCheck is a tool that helps WordPress users quickly check plug-in compatibility and performance. It is mainly used to identify whether the currently installed plug-in has problems such as incompatible with the latest version of WordPress, security vulnerabilities, etc. 1. How to start the check? After installation and activation, click the "RunaScan" button in the background to automatically scan all plug-ins; 2. The report contains the plug-in name, detection type, problem description and solution suggestions, which facilitates priority handling of serious problems; 3. It is recommended to run inspections before updating WordPress, when website abnormalities are abnormal, or regularly run to discover hidden dangers in advance and avoid major problems in the future.

The most effective way to prevent comment spam is to automatically identify and intercept it through programmatic means. 1. Use verification code mechanisms (such as Googler CAPTCHA or hCaptcha) to effectively distinguish between humans and robots, especially suitable for public websites; 2. Set hidden fields (Honeypot technology), and use robots to automatically fill in features to identify spam comments without affecting user experience; 3. Check the blacklist of comment content keywords, filter spam information through sensitive word matching, and pay attention to avoid misjudgment; 4. Judge the frequency and source IP of comments, limit the number of submissions per unit time and establish a blacklist; 5. Use third-party anti-spam services (such as Akismet, Cloudflare) to improve identification accuracy. Can be based on the website
