wp_new_comment() – Adds a new comment to the database.
You appear to be a bot. Output may be restricted
Description
Adds a new comment to the database.
Filters new comment to ensure that the fields are sanitized and valid before inserting comment into database. Calls comment_postcomment_post action with comment ID and whether comment is approved by WordPress. Also has preprocess_comment filter for processing the comment data before the function handles it.
We use REMOTE_ADDR
here directly. If you are behind a proxy, you should ensure that it is properly set, such as in wp-config.php, for your environment.
See https://core.trac.wordpress.org/ticket/9235
