Use symfony objects for sending Swift_message - php

Question

I am trying to create an email that messages all users that are tied to a specific company. If I take the recipients array and add it to my email and test with a single email, I can see all of the user emails print out in the test email. When I try and pass that same recipients array into setTo instead of using a single to email address I get a message "Warning: Illegal offset type"
$company = $this->getDoctrine()->getRepository('Bundle:Customer')->findOneBy(array('accountId' => $compare->getCustomerAccount()));
$recipients = [];
foreach($company->getUsers() as $user){
array_push($recipients, $user);
}
array_push($recipients, $company->getCsr());
$newComment = new Comment();
$newComment->setDetails($comment);
$newComment->setUser($this->getUser());
$em = $this->getDoctrine()->getManager();
$em->flush();
$message = \Swift_Message::newInstance()
->setSubject($subject)
->setFrom($fromEmail)
->setTo($recipients)
->setBody(
$this->renderView(
'Bundle:Comment:email_users.html.twig', array(
'subject' => $subject,
'comment' => $comment,
'company' => $company,
'proof' => $proof
)
)
)
->setContentType('text/html')
;
$this->get('mailer')->send($message);

Answer 1

Se setTo accept an associative array with email and name (check here in the doc), so you should modify your code with something like:
foreach($company->getUsers() as $user){
array_push($recipients, [$user->getEmail() => $user->getName()]);
}
array_push($recipients, $company->getCsr()->getEmail());
Hope this help

Answer 2

The error occurs, because you're trying to set the recipients with an array of $user objects instead of an associative array of strings. When trying to access the index of an array with an object or an array as the index, you will see that error message.
Your $recipientsarray should look more like array('receiver#domain.org', 'other#domain.org' => 'A name') and you should be fine.
Your code could look like this:
$recipients = [];
foreach($company->getUsers() as $user){
array_push($recipients, $user->getEmail());
}
array_push($recipients, $company->getCsr()->getEmail());
I'm just assuming that your user object has a getter method getEmail() which returns the user email address as a string.

Answer 3

I added the following to my user class which extends BaseUser:
/**
* Sets the email.
*
* #return string
*/
public function getEmail()
{
return parent::getEmail();
}
Then I was able to run getEmail on each user
$recipients = [];
foreach($company->getUsers() as $user){
array_push($recipients, $user->getEmail());
}
array_push($recipients, $company->getCsr()->getEmail());
Email was sent successfully!
