php - laravel variable not defined -

this weird. sure missing simple. have following code:

$producttoken = input::get('key');         $products = new product;         $useremail = $products->activateproduct($producttoken);          $productdetailsarray = $products->getproductdetailsforuseremail($producttoken);          $emaildata = $productdetailsarray;         mail::send('emails.productreleased', $emaildata, function($message){             $message->to($useremail)->subject('notification - product released public!');         });  

it supposed activate product in database , send email user. email of user in $useremail , when did var_dump, shows. somehow line throws error $useremail undefined:

$message->to($useremail)->subject('notification - product released public!'); 

this error get:

undefined variable: useremail 

i used mail function before instead of passing variable passed input::get('email') because in registration form. right now, don't have access input rather $useremail. please advise.

you using callback function @ time function called, useremail variable out of scope. should send useremail variable function, maybe :

mail::send('emails.productreleased', $emaildata, function($message) use ($useremail) {     $message->to($useremail)->subject('notification - product released public!'); });  

see http://www.php.net/manual/fr/functions.anonymous.php#example-191 information lambda (anonymous) function , context.
