When you use anonymous function to pass variables you should use use construction
public function email($name, $email2) {
$data = array('name'=> $name);
Mail::send('mail',$data,function($message) use ($name, $email2) {
$message->to($email2, $name)->subject('Deposit Confirmation');
$message->attach(public_path('document.pdf'));
$message->from('xxx#xxx.pt', 'XXX');
});
}
Here you can find more examples about anonymous functions https://www.php.net/manual/en/functions.anonymous.php
Here simple example from official documentation
$message = "hello";
// Inherit $message
$example = function () use ($message) {
var_dump($message);
};
$example();
// Output: string(5) "hello"
