根据观察，Wordpress的垃圾评论中有95%是全英文评论和含有日文字符的评论，如果能够禁止这些评论的提交，也就基本上达到了Wordpress防止垃圾评论的目的了。今天就为大家分享WordPress阻止全英文和含有日文字符评论方法。
将以下代码放入function.php中，就可以阻止全英文的评论了。
function scp_comment_post( $incoming_comment ) {
$pattern = \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’/[一-龥]/u\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’;
// 禁止全英文评论
if(!preg_match($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\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’);
3、将以下代码放入function.php中，就可以阻止包含任意日文字符的评论了。
// 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\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’);
