我在过滤联系表单消息中的坏词时遇到问题。它会删除除单词首字母之外的所有消息。有什么帮助吗?
下面只是获取信息
<?php
$error = '';
if(!empty($_POST['username'])) $username = $_POST['username'];
if(!empty($_POST['email'])) $email = $_POST['email'];
if(!empty($_POST['subject'])) $subject = check($_POST['subject']);
if(!empty($_POST['message'])) $msg = filter($_POST['message']);
这是我试图用来去除坏词并替换它们的功能
$bad_words = array(
'word1' => 'gosh',
'word2' => 'darn',);
function filter($matches) {
global $bad_words;
$replace = $bad_words[$matches[0]];
return !empty($replace) ? $replace : $matches[0];
}
检查下拉选项并且不允许通过电子邮件发送某些主题。
function check($str){
global $error;
if ($str == 'Mean Spirited Comment'){
$error = 'You sent a Mean-Spirited Comment';
} else if ($str =='Political Comment'){
$error = 'You sent a Political Comment';
}
return $str;
}
放置信息并发送
$to = 'email@email.com';
if (!empty($subject) && !empty($msg) && !empty($email) && !empty($username)){
if ($error == ''){
mail($to, $subject, $msg, 'From:' . $email);
} else {
print $error;
}
}
?>
