Determines if a comment exists based on author and date.
For best performance, use$timezone = 'gmt'
, which queries a field that is properly indexed. The default value
for $timezone
is 'blog' for legacy reasons.Sorgenti
function comment_exists( $comment_author, $comment_date, $timezone = 'blog' ) { global $wpdb; $date_field = 'comment_date'; if ( 'gmt' === $timezone ) { $date_field = 'comment_date_gmt'; } return $wpdb->get_var( $wpdb->prepare( "SELECT comment_post_ID FROM $wpdb->comments WHERE comment_author = %s AND $date_field = %s", stripslashes( $comment_author ), stripslashes( $comment_date ) ) ); }
