Getting error when sending an email in Laravel 4.2

Question

I have an error in Laravel when I am sending an email.

I have a form with a select tag and when I select the user and click submit I need to send him a mail after I select it.

Here is my Controller method:

public function store()
{

    $customerId = Input::get('customerid');

    $invoice = New Invoice ;

    $invoice->customerid = Input::get('customerid');

    $invoice->save();

    if ($invoice->save()) {

        $email = Customer::whereRaw(' id = :customer',array('customer'=> $customerId ))->first(array('email'));

        Mail::send('invoices.mail', array($pinvoices,$unpinvoices), function($message) {
            $message->to($email , 'Name')->subject('your invoices ');
        }); 
    }
}

When I click submit I get an error :

Undefined variable: email

and when I tried to add my email as a static value like :

$email = "[email protected]" ;
     Mail::send('invoices.mail', array($pinvoices,$unpinvoices), function($message){
                $message->to($email , 'Name')->subject('your invoices ');
            }); 

It's also getting the same error !!

and when i put the value like this :

 Mail::send('invoices.mail', array($pinvoices,$unpinvoices), function($message){
            $message->to("[email protected]" , 'Name')->subject('your invoices ');
        }); 

it works perfectly !

Closures work just like a regular function. You need to inject your outer scope variables into function's scope.

Mail::send('invoices.mail', array($pinvoices,$unpinvoices), function($message) use ($email)
{
    $message->to($email , 'Name')->subject('your invoices ');
});
