Support for recipient variables when batch-sending about mailgun

[azamat-sharapov]

Okay, important note to anyone who can't get this work: Make sure you are not using catch_all config option! It won't work with it.

Here's my two pence:
Message.php

public function recipientVariables($variables)
{
    if ( is_array($variables) ) {
        $this->{'recipient-variables'} = json_encode($variables);
    }
}

Usage in Controller:

$users = User::take(2)->get();

$variables = [], $data = [];
foreach ($users as $user) {
    $variables[$user->email] = ['id' => $user->id, 'first_name' => $user->first_name];
}

Mailgun::send('emails.newsletter', $data, function($message) use ($users,$variables)
{
    foreach ($users as $user) {
        $message->to($user->email, $user->first_name . ' ' . $user->last_name);
    }

    $message->recipientVariables($variables);
});

(Apologies, can't get Github to format it nicely)

@kJamesy I will definitely have a look at it.

[kJamesy]

Great, thanks.

[Bogardo]

@kJamesy It has been added.
There are now two ways to register the recipient variables

1. The way you proposed with a recipientVariables method
2. Passing them as an array with the to method

$recipients = array(
    "[email protected]" => array(
        'first' => 'Foo',
        'last'  => 'Bar'
    ),
    "[email protected]" => array(
        'first' => 'John',
        'last'  => 'Doe'
    )
);
Mailgun::send('emails.welcome', $data, function($message) use ($recipients)
{
    $message->to($recipients);
});

And in your emails you can use the variables like this:

 Hi there %recipient.first% %recipient.last%

I'll try to update the docs tomorrow.
Please let me know if this works for you.

[kJamesy]

Cool stuff!
Will the to field still show the user first name + last name when the email is received?

[Bogardo]

If I understand your question correctly, yes you can:

$recipients = array(
    "Foo Bar <[email protected]>" => array(
        'first' => 'Foo',
        'last'  => 'Bar'
    ),
    "John Doe <[email protected]>" => array(
        'first' => 'John',
        'last'  => 'Doe'
    )
);

[kJamesy]

Yes, I didn't even read the code correctly, was 3AM when I saw this! That makes sense. Cheers

Hi!

Could you please make this work with ->cc and ->bcc as well? I receive the Mailgun error "The parameters passed to the API were invalid. Check your inputs!".

Thank you!

[kJamesy]

@elambro, this is a very good coincidence because I am having the exact same error this today! Not seen it before. Not using CC or BCC either!

[elambro]

@kJamesy, It must be for a different reason though. Mine works perfectly fine with recipient variables as

    $message->to($variables); $message->bcc($email_address);

But it fails if I try to use variables in the bcc field. e.g.

    $message->to($variables); $message->bcc($other_variables);

[Bogardo]

I'll take a look at it.

[azamat-sharapov]

I can't get this work. Has anybody used this feature? I tried both ways like described above, but variables don't get replaced in message body.
