PHP表单字段已填充，但在电子邮件中收到空字段

我有一个php文件，它将表单的字段发送到电子邮件地址。但是，有些字段是空的。以下是电子邮件的一个示例：

“我的名字是：D

我的名字是：卡米尔

我的电子邮件是：dollec@xxx.fr

我的电话号码是：0xxxxxxx6

我的职业是：

我的员工是：

我的位置是：

我的评论：bbb“

下面是PHP代码：

    //If the form is submitted
    if($cap_val == 1) {

缺少下划线字符：

更改它：

$profession = trim($POST['profession']);
$employeur = trim($POST['employeur']);
$lieu = trim($POST['lieu']);

致：

享受你的代码吧！
这种情况会发生。别担心。@blondie你能在我的回复中设置ok复选框吗？谢谢：）
$profession = trim($_POST['profession']);
$employeur = trim($_POST['employeur']);
$lieu = trim($_POST['lieu']);
