Using get_comment_author_link to get comment author link in WordPress
The get_comment_author_link function in WordPress retrieves the HTML link to the URL of the author of a comment. This function is typically used within the context of displaying comments on a WordPress site.
When a user submits a comment, they often provide a URL along with their name. The get_comment_author_link function generates an HTML anchor tag that links the comment author’s name to their provided URL. If no URL is provided by the author, the function will return just the author’s name without a hyperlink.
This function is useful for:
- Displaying comment author names as clickable links
- Providing a way for site visitors to visit the comment author’s website directly from the comments section
- Maintaining a consistent format for displaying comment author information
Parameters
$comment_id(int|WP_Comment), optional. WP_Comment object or the ID of the comment for which to retrieve the author’s link. Defaults to the current comment.
Return Value
The function returns a string containing the comment author’s name or an HTML link to the author’s URL.
Examples
How to Display Comment Author Links in a List of Recent Comments
<?php
$recent_comments = get_comments(array(
'number' => 5, // Number of recent comments to fetch
'status' => 'approve' // Only approved comments
));
if (!empty($recent_comments)) {
echo '<ul>';
foreach ($recent_comments as $comment) {
echo '<li>' . get_comment_author_link($comment->comment_ID) . '</li>';
}
echo '</ul>';
} else {
echo '<p>No recent comments found.</p>';
}
?>
