    The have_comments() function in WordPress is a vital tool for theme developers and plugin authors when they need to handle comments in a WordPress site. Here's a detailed explanation and sample usage of the function:

    Function Declaration:

    have_comments(): bool
    

    Purpose:

    • Determines whether the current WordPress query has comments to loop over.
    • It is primarily used within the WordPress Loop for comments, which is similar to the main WordPress Loop but specifically targets comments.

    Return Value:

    • bool:
      • Returns True if comments are available.
      • Returns False if no more comments are available.

    Usage Context:

    • This function is typically used in a WordPress theme's comments.php template file.
    • It is part of the standard loop structure for iterating over comments.

    Sample Usage:

    Here's a basic example to illustrate how have_comments() might be used in a WordPress theme:

    <?php
    // Check if there are comments
    if (have_comments()) : 
        // Loop through and list the comments
        while (have_comments()) : 
            the_comment();
            // Display the comment here
            // For example, using comment_text() and comment_author()
        endwhile;
    else :
        // Display a message if there are no comments
        echo 'No comments yet.';
    endif;
    ?>
    

    Explanation of Sample Code:

    • Check for Comments: The if (have_comments()) statement checks if there are any comments to display.
    • Looping Through Comments: The while (have_comments()) loop iterates through each comment.
    • Displaying Comments: Inside the loop, you can use functions like comment_text() and comment_author() to display the comment's content and author.
    • No Comments Case: If there are no comments, the else statement executes, displaying a message like 'No comments yet.'

    Additional Notes:

    • This function is part of a set of template tags in WordPress for handling comments.
    • It's important to follow WordPress coding standards and best practices when using this function in theme or plugin development.

    By incorporating have_comments() in your theme, you can create dynamic comment sections that respond to the presence or absence of user comments, enhancing the interactivity and user engagement on the site.
