Laravel Mail - 找不到PathToFile变量

Question

I am writing this simple code to send a mail with attachment, however, I am not able to pass the path to the file variable.

$pathToFile = "Sale-".$id.".csv";

Mail::send(array('html' => 'sales.invoice_template'), $data, function($message)
        {
            $message->to('[e-mail]'); // dummy email
            $message->attach($pathToFile);
        });

The above code throws:

Undefined variable: pathToFile

Also, I tried passing a variable (added $pathToVariable with $message in above closure) to the closure but it throws following error:

Missing argument 2 for SaleController::{closure}()

It basically doesn't identify any variable outside the closure. Can anyone please help me out here?

Answer 1

You can try this:

$pathToFile = "Sale-".$id.".csv";

Mail::send(array('html' => 'sales.invoice_template'), $data, function($message) use ($pathToFile)
{
    $message->to('[e-mail]'); // dummy email
    $message->attach($pathToFile);
});

The instruction:

use ($pathToFile)

...allows you to use your variable in the closure.
