在外观–主题–编辑function.php文件,最后加入:
// 禁止全英文评论
function scp_comment_post( $incoming_comment ) {
$pattern = '/[一-龥]/u';
if(!preg_match($pattern, $incoming_comment['comment_content'])) {
wp_die( "You should type some Chinese word (like \"你好\") in your comment to pass the spam-check, thanks for your patience! 您的评论中必须包含汉字!" );
}
return( $incoming_comment );
}
add_filter('preprocess_comment', 'scp_comment_post');

// 禁止日文评论
function BYMT_comment_jp_post( $incoming_comment ) {
$jpattern ='/[ぁ-ん]+|[ァ-ヴ]+/u';
if(preg_match($jpattern, $incoming_comment['comment_content'])){
wp_die( "禁止有日文字符的评论 You should type some Chinese word" );
}
return( $incoming_comment );
}
add_filter('preprocess_comment', 'BYMT_comment_jp_post');
