Function and usage of get_comments() in wordpress


Answers ( 1 )


    The get_comments() function in WordPress is a versatile tool for retrieving a list of comments, either for the entire blog or for individual posts. Here's a detailed explanation of its functionality and usage:


    • Name: get_comments()
    • Purpose: Retrieves a list of comments.


    • This function is used to fetch comments based on specified criteria. It can be used to get comments from the entire blog or from a specific post.
    • It is highly flexible, allowing you to filter and sort the comments in various ways.


    • $args (string|array, optional): This parameter allows you to specify the criteria for the comments you want to retrieve. It can be either a string or an array. The details of this parameter are based on the WP_Comment_Query::__construct() method, which provides a wide range of options for filtering and sorting comments. Some examples of these options include:
      • 'post_id': to get comments from a specific post.
      • 'status': to filter comments by their status (e.g., approved, pending).
      • 'number': to limit the number of comments retrieved.
      • 'orderby': to sort comments by parameters like date, author, etc.
      • Many other options are available for advanced querying.
    • Default Value: An empty string '', which means it will fetch all comments without any specific filtering or sorting if no argument is provided.


    • Type: WP_Comment[] | int[] | int
    • The function returns:
      • An array of WP_Comment objects if comments are found.
      • An array of comment IDs or a single integer representing the number of comments found if the $count argument is set to true.
      • This versatility in the return type makes the function suitable for different needs, like simply counting comments or retrieving detailed comment information.

    Sample Usage:

    To illustrate how get_comments() can be used, here's an example:

    $args = array(
        'post_id' => 123, // Replace with your specific post ID
        'status' => 'approve',
        'number' => 10,
        'orderby' => 'comment_date_gmt',
        'order' => 'DESC'
    $comments = get_comments($args);
    foreach ($comments as $comment) {
        // Process each comment
        echo 'Comment author: ' . $comment->comment_author . '<br>';
        echo 'Comment content: ' . $comment->comment_content . '<br>';
        // Add more fields as needed

    In this example, get_comments() is used to fetch the last 10 approved comments from a specific post, sorted by their date in descending order. The loop then iterates over each comment, displaying the author and content.

    This function is particularly useful for developers who need to customize the way comments are displayed or processed in a WordPress site.
