Hello Im使用一个自定义过滤器pre_comment_approved 以习惯的方式寻找坏话。现在，当注释被标记时，它会返回spam.
我如何将错误发回评论页面，以便用户知道他/她的电子邮件由于使用了列入黑名单的单词而被发送到垃圾邮件？
谢谢
function my_wp_blacklist_check( $approved , $commentdata ) {
$mod_keys = trim( get_option(\'blacklist_keys\') );
if ( \'\' == $mod_keys )
return false; // If moderation keys are empty
$words = explode("\\n", $mod_keys );
foreach ( (array) $words as $word ) {
$word = trim($word);
str_pad($word, 1, STR_PAD_BOTH);
// Skip empty lines
if ( empty($word) ) { continue; }
// Do some escaping magic so that \'#\' chars in the
// spam words don\'t break things:
$word = preg_quote($word, \'#\');
$pattern = "#\\b$word\\b#i";
if (preg_match($pattern, $commentdata[\'comment_content\'])) {
return \'spam\';
}
}
return true;
}
add_filter( \'pre_comment_approved\' , \'my_wp_blacklist_check\' , \'99\', 2 );

这是我以前处理将消息传递回用户的方式：在当前函数中，设置transient 随信附上：
set_transient( \'admin_notice\', \'Please put down your weapon. You have 20 seconds to comply.\' );
然后添加一个新的挂钩函数：
function admin_notices() {
$notice = get_transient( \'admin_notice\' );
if ( $notice ) {
echo \'<div class="error"><p>\' . $notice . \'</p></div>\';
delete_transient( \'admin_notice\' );
}
}
add_action( \'admin_notices\', \'admin_notices\' );
