This is What to Do When the comments_template() Function in WordPress Plugins Doesn't Display Comments
If you're a WordPress plugin developer, you've probably used the comments_template()
function before. This function is designed to load the comments template for a post or page, displaying the comments section for your users.
However, you may have run into a situation where the comments_template()
function isn't displaying the comments as expected. Perhaps the comments section isn't showing up at all, or it's only displaying on certain pages.
In this article, we'll dive into why the comments_template()
function may not be working as expected, and provide some solutions to help you get it back on track.
Understanding the comments_template() Function
Before we get into troubleshooting, let's quickly review how the comments_template()
function works.
According to the WordPress Code Reference, the comments_template()
function "will not display the comments template if not on single post or page, or if the post does not have comments."
In other words, the function checks a few key things:
- Is this a single post or page? The function will only display the comments template if you're on a single post or page, not on an archive or category page.
- Does the post have comments? If the post or page doesn't have any comments, the function won't display the comments template.
If both of these conditions are met, the comments_template()
function will load the appropriate comments template file and display the comments section.
Why Isn't comments_template() Working?
Now that we understand how the comments_template()
function works, let's look at some common reasons why it might not be displaying the comments section as expected.
-
You're not on a single post or page: If you're calling the comments_template()
function on an archive, category, or other non-singular page, it won't display the comments. Make sure you're only using this function on single post or page templates.
-
The post doesn't have any comments: If the post or page you're viewing doesn't have any comments, the comments_template()
function won't display anything. This is by design, as the function is meant to only show the comments section if there are comments to display.
-
The comments template file is missing or incorrect: The comments_template()
function looks for a specific comments template file in your theme. If this file is missing, named incorrectly, or doesn't contain the proper markup, the function won't be able to display the comments.
-
You're not passing the correct post ID: If you're calling the comments_template()
function outside of the main WordPress loop, you'll need to make sure you're passing the correct post ID. If the post ID is incorrect, the function won't be able to find the right comments to display.
-
There's a plugin conflict: If you have other plugins installed that interact with the comments system, they could be interfering with the comments_template()
function. Try deactivating any relevant plugins and see if that resolves the issue.
-
Your theme is overriding the comments template: In some cases, your theme may be providing its own custom comments template, which could be preventing the comments_template()
function from working as expected. You may need to investigate your theme's code to see if it's overriding the default comments template.
Troubleshooting the comments_template() Function
Now that we've covered some of the common reasons why the comments_template()
function might not be working, let's dive into some troubleshooting steps you can take to fix the issue.
- Check the template conditions: First, make sure you're calling the
comments_template()
function on a single post or page template. You can do this by checking the global $post
object and the is_single()
or is_page()
functions.
if ( is_single() || is_page() ) {
comments_template();
}
- Verify the post has comments: Next, check if the post or page you're on has any comments. You can use the
get_comments_number()
function to do this:
if ( get_comments_number() > 0 ) {
comments_template();
}
-
Inspect the comments template file: If the first two steps check out, the issue might be with the comments template file itself. Make sure the file is named correctly (usually comments.php
) and that it contains the proper markup and WordPress functions.
-
Pass the correct post ID: If you're calling the comments_template()
function outside of the main WordPress loop, make sure you're passing the correct post ID. You can do this by using the get_the_ID()
function or by manually setting the $post
global:
global $post;
$post = get_post( $post_id );
comments_template();
-
Deactivate other plugins: As mentioned earlier, plugin conflicts can sometimes interfere with the comments_template()
function. Try deactivating any plugins that interact with the comments system and see if that resolves the issue.
-
Check your theme's code: Finally, make sure your theme isn't overriding the default comments template. You can do this by looking for any custom comments template files or functions in your theme's code.
By following these troubleshooting steps, you should be able to identify and resolve the issue with the comments_template()
function in your WordPress plugins.

function is a powerful tool for displaying the comments section on your WordPress posts and pages. However, it's important to understand how it works and what conditions need to be met for it to display the comments correctly.
If you're experiencing issues with the comments_template()
function, be sure to check the template conditions, verify the post has comments, inspect the comments template file, pass the correct post ID, look for plugin conflicts, and review your theme's code.
