Upgrade Emails


What has been changed

  • Only small things like the method names and the loading of the library have changed.

Upgrade Guide

  1. Within your class change the $this->load->library('email'); to $email = service('email');.

  2. From that on you have to replace every line starting with $this->email to $email.

  3. The methods in the Email class are named slightly different. All methods, except for send(), attach(), printDebugger() and clear() have a set as prefix followed by the previous method name. bcc() is now setBcc() and so on.

  4. The config attributes in app/Config/Email.php have changed. You should have a look at the Setting Email Preferences to have a list of the new attributes.

Code Example

$this->email->from('[email protected]', 'Your Name');
$this->email->to('[email protected]');
$this->email->cc('[email protected]');
$this->email->bcc('[email protected]');

$this->email->subject('Email Test');
$this->email->message('Testing the email class.');

$email = service('email');

$email->setFrom('[email protected]', 'Your Name');
$email->setTo('[email protected]');
$email->setCC('[email protected]');
