定义Mail :: send()方法的电子邮件地址 [英] Defining the email address for the Mail::send() method

问题描述

很抱歉，如果我是Laravel的新手，但我在这里错过了一些东西，但是当我向Mail :: send()方法发送闭包以定义邮件收件人时，如果该电子邮件地址在全球范围内可用，则可以很好地工作范围，像这样:

Apologies if I'm missing something here as I'm new to Laravel but when I send a closure to the Mail::send() method to define the mail recipient, it works fine if the email address is available the global scope, like this:

Mail::send('frontend.emails.default', $data, function($message) 
{
    $message->to(Input::get('email'))->subject('Hi');
});

但是如何在范围内将值传递给调用方法呢?例如:

But how can I pass a value in that's scoped to the calling method? For example:

$user = User::find($id);

Mail::send('frontend.emails.default', $data, function($message) 
{
    $message->to($user->email)->subject('Hi');
});

我尝试将其添加到$ data数组中，但这在视图中使用，在回调中不可用.

I tried adding it to the $data array but that's used in the view and isn't available in the callback.

感谢您的帮助.

推荐答案

PHP中有一个已记录的小功能，可让您将变量从当前作用域传递到闭包中.简而言之，您需要use ($user) ...

There's a little documented feature in PHP that allows you to pass variables from the current scope into a closure. In short, you need to use ($user)...

$user = User::find($id);

Mail::send('frontend.emails.default', $data, function($message) use ($user)
{
    $message->to($user->email)->subject('Hi');
});
