The WP_Comment_Query class allows developers to query the WordPress database tables wp_comments and wp_commentmeta. In simple English, it allows the theme’s or plugin’s developer to retrieve post comments through a GUI.
For this reason, we’ve put together this code snippet generator tool that allows developers and first-time theme authors to integrate comment querying functionality into their WordPress themes. But before we begin, let’s take a closer look at what WP_Comment_Query is and how you can use it.
What Is WP_Comment_Query and How Can I Use It?
The WP_Comment_Query class is designed to take all the heavy lifting out of querying comments in WordPress. Unlike before, we don’t have to query the WordPress database tables directly – we can simply use modular and readable parameters and arguments to do it for us.
WP_Comment_Query is a class, defined in wp-includes/class-wp-comment-query.php, that allows querying WordPress database tables ‘wp_comments‘ and ‘wp_commentmeta‘. The class was introduced in Version 3.1. – WordPress Codex
WP_Comment_Query enables developers to build pages that allow users to browse the site’s comments based on the date they were published, their popularity, and who wrote them. Now that you have a fair idea of how you can use WP_Comment_Query, let’s take a look at how you can get started using this code snippet generator tool.
How Do I Use This WP_Comment_Query Snippet Generator Tool?
This WP_Comment_Query code snippet generator tool was designed to help both developers and first-time theme builders query comments for their WordPress themes without having to code them by hand. To use this tool, simply enter the values next to each field based on your preference and the tool will generate a theme-specific code snippet for you.
Let’s take a look at each individual field one at a time:
- Theme Slug: Enter your theme’s slug into this field in all lowercase letters, numbers and/or underscores. This value will be used to prefix functions and variables that would otherwise be incompatible with the WordPress core or any installed themes or plugins. Typically, this is the same string as the text domain, with all hyphens replaced by underscores.
- Unique Query Variable Identifier: Enter a descriptive name for your query variable. It will be used to identify the query variable. The query variable identifier should be a unique name in all lowercase letters, numbers and/or underscores.
- Include the Loop: Check this box if you’d like to have the code in the loop be processed on each post. By default, this value is set to false.
- Comment ID: Enter the comment’s unique ID here. This field accepts an int value.
- Comment Parent ID: Enter the parent comment’s ID here in case of nested comments. 0 value denotes top-level comments.

How Do I Add the Code Snippet to My Website?
The quickest way to add the generated code snippet to your WordPress site is via FTP. Start off by downloading the theme’s functions.php file to your desktop via an FTP client. Next, open it up in a text editor and paste the code from the Custom Comments Query section at the bottom of the file. Hit the Save button and re-upload it to your theme’s directory.
Alternatively, you can add the generated code snippet to your site by pasting it directly into your current theme’s functions.php file. Simply head over to Appearance > Editor from the admin panel, find your active theme’s functions.php file, and insert the code at the bottom of the file.
WP_Comment_Query offers a powerful and flexible way for developers to query comments from the WordPress database tables through a standardized interface. Hopefully, this code snippet generator tool will help you add comments querying functionality in your WordPress themes and save you some time and effort from having to code it by hand.
