Passing data to a closure in Laravel 4
提问by Benjamin Gonzalez
I'm trying to use the Mail Class in Laravel 4, and I'm not able to pass variables to the $m object.
我试图在 Laravel 4 中使用邮件类，但我无法将变量传递给 $m 对象。
the $team object contains data I grabbed from the DB with eloquent.
$team 对象包含我雄辩地从数据库中抓取的数据。
Mail::send('emails.report', $data, function($m)
{
$m->to($team->senior->email, $team->senior->first_name . ' '. $team->senior->last_name );
$m->cc($team->junior->email, $team->junior->first_name . ' '. $team->junior->last_name );
$m->subject('Monthly Report');
$m->from('[email protected]', 'Sender');
});
For some reason I get an error where $team object is not available. I suppose it has something to do with the scope.
出于某种原因，我收到一个错误，其中 $team 对象不可用。我想这与范围有关。
Any ideas ?
有任何想法吗 ？

If you instantiated the $teamvariable outside of the function, then it's not in the functions scope. Use the usekeyword.
如果$team在函数外部实例化变量，则它不在函数范围内。使用use关键字。
$team = Team::find($id);
Mail::send('emails.report', $data, function($m) use ($team)
{
$m->to($team->senior->email, $team->senior->first_name . ' '. $team->senior->last_name );
$m->cc($team->junior->email, $team->junior->first_name . ' '. $team->junior->last_name );
$m->subject('Monthly Report');
$m->from('[email protected]', 'Sender');
});
Note: The function being used is a PHP Closure (anonymous function)It is not exclusive to Laravel.
注意：正在使用的函数是一个PHP 闭包（匿名函数），它不是 Laravel 独有的。
