Upgrade Emails

Documentation

• Email Documentation CodeIgniter 3.x
• Email Documentation CodeIgniter 4.x

What has been changed

• Only small things like the method names and the loading of the library have changed.
• The behavior when using the SMTP protocol has been slightly changed. You may not be able to communicate with your SMTP server properly if you use the CI3 settings. See SSL versus TLS for SMTP Protocol and Email Preferences.

Upgrade Guide

1. Within your class, change $this->load->library('email'); to $email = service('email');.
2. From then on, you have to change $this->email to $email in every line starting with it.
3. The methods in the Email class are named slightly differently. All methods, except for send(), attach(), printDebugger() and clear(), have set as a 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 for a list of the new attributes.

Code Example

<?php

$this->load->library('email');

$this->email->from('your@example.com', 'Your Name');
$this->email->to('someone@example.com');
$this->email->cc('another@another-example.com');
$this->email->bcc('them@their-example.com');

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

$this->email->send();

CodeIgniter Version 4.x
