我在Wordpress网站有一个简单的联系表单，需要一些保护。保护带有空字段的垃圾邮件（PHP）的表格（蜜罐）
我给了它两个名为“网站”和“电子邮件”的空字段，并用CSS（visibility：hidden;）隐藏它们。到现在为止还挺好。
现在的问题是，我不能给PHP命令
if(isset($_POST['website'])) die();
if(isset($_POST['email'])) die();
在我的PHP文件中的正确位置。你能告诉我该把它放在哪里吗？
这是我的PHP文件：
<?php
if(isset($_POST['website'])) die();
if(isset($_POST['email'])) die();
if(isset($_POST['submitted'])) {
if(trim($_POST['contactVorname']) === '') {
$vornameError = '*';
$hasError = true;
} else {
$vorname = trim($_POST['contactVorname']);
}
if(trim($_POST['contactName']) === '') {
$nameError = '*';
$hasError = true;
} else {
$name = trim($_POST['contactName']);
}
if(trim($_POST['contactEmail']) === '') {
$emailError = '*';
$hasError = true;
} else if (!preg_match("/^[[:alnum:]][a-z0-9_.-]*@[a-z0-9.-]+\.[a-z]{2,4}$/i", trim($_POST['contactEmail']))) {
$emailError = '*';
$hasError = true;
} else {
$email = trim($_POST['contactEmail']);
}
if(trim($_POST['unternehmen']) === '') {
/* $unternehmenError = '*';
$hasError = true; */
} else {
$unternehmen = trim($_POST['unternehmen']);
}
if(trim($_POST['ort']) === '') {
/* $ortError = '*';
$hasError = true; */
} else {
$ort = trim($_POST['ort']);
}
if(trim($_POST['telefon']) === '') {
/* $telefonError = '*';
$hasError = true; */
} else {
$telefon = trim($_POST['telefon']);
}
if(trim($_POST['betreff']) === '') {
$betreffError = '*';
$hasError = true;
} else {
$betreff = trim($_POST['betreff']);
}
if(trim($_POST['comments']) === '') {
$commentError = '*';
$hasError = true;
} else {
if(function_exists('stripslashes')) {
$comments = stripslashes(trim($_POST['comments']));
} else {
$comments = trim($_POST['comments']);
}
}
if(!isset($hasError)) {
$emailTo = get_option('tz_email');
if (!isset($emailTo) || ($emailTo == '')){
$emailTo = get_option('admin_email');
}
$subject = 'Kontaktformular | '.$vorname.' '.$name;
$body = "\n.: Kontaktformular-E-Mail :. \n\nName: $vorname $name \nE-Mail: $email \n\nUnternehmen: $unternehmen \nOrt: $ort \nTelefon: $telefon \n\nBetreff: $betreff \n\nNachricht: $comments";
$headers = 'From: '.$vorname.' '.$name.' <'.$emailTo.'>' . "\r\n" . 'Reply-To: ' . $email;
wp_mail($emailTo, $subject, $body, $headers);
$emailSent = true;
}

眼下，形式被完全挡在外面，在发送数据之后，虽然有问题的两个字段未填写。
非常感谢。我不知道isset设置。 – vega
