You'll need to grab the referer and check if it is contains 'admin'. Try the following
您需要获取引用并检查它是否包含“admin”。尝试以下
$referer = Request::referer();
// or
// $referer = Request::server('HTTP_REFERER');
if (strpos($referer,'admin') !== false) {
dd('coming from admin')
}
Edit #1: As pointed out by @tomvo you can also use URL::previous()instead of Request::referer()in L4
编辑 #1：正如@tomvo 所指出的，您也可以在 L4 中使用URL::previous()而不是Request::referer()
Edit #2: It's actually mispelled as refererinstead of referreras point out by @JamesF
编辑#2：它实际上拼错了，referer而不是@JamesFreferrer指出的那样
Edit #3: In Laravel 5 the Request::referer()method doesn't seem to exist anymore, you can still get it by using Request::header('referer')as point out by @TheSerenin
编辑 #3：在 Laravel 5 中，该Request::referer()方法似乎不再存在，您仍然可以通过使用Request::header('referer')@TheSerenin 指出的方法来获取它
