Displaying the comments link on a WordPress post using comments_link
The comments_link function in WordPress is designed to generate a URL that leads to the comments section of a particular post or page. This function can be useful in various situations where a direct link to the comments section is required. For instance, it can be used to create a comments link in a post meta data section, or in a list of posts, so that users can quickly navigate to the comments section of a post.
When the comments_link function is called, it retrieves the URL of the comments section of the current post in the WordPress Loop. The function does not return the URL, but instead directly outputs it to the browser. This means that it should be used in a context where it is appropriate to output HTML directly.
The comments_link function does not include the number of comments in the link. If you need to display the number of comments along with the link, you should use the comments_popup_link function instead.
The comments_link function is part of the WordPress Comments API, which provides a set of functions and hooks for working with comments in WordPress. Other functions in the API include get_comments, wp_list_comments, and comment_form.
