To send an email in CodeIgniter, you have to load the email library first. Use the following line of code to load the CodeIgniter’s Email library.


Send Text Email:

Here is an example code to send text email in CodeIgniter.

$this->email->subject('Test Email (TEXT)');
$this->email->message('Text email testing by CodeIgniter Email library.');

Send HTML Email:

To send an email with HTML content, set a preference (mailtype) by passing an array of preference value (html) to the email initialize function. Here is an example code to send HTML email in CodeIgniter.

$htmlContent '<h1>HTML email testing by CodeIgniter Email Library</h1>';
$htmlContent .= '<p>You can use any HTML tags and content in this email.</p>';
$config['mailtype'] = 'html';
$this->email->subject('Test Email (HTML)');

Send Email with Attachment:

Use attach() function of Email class to attach files in email. Here is an example code to send an email with attachment in CodeIgniter.

$htmlContent '<h1>HTML email with attachment testing by CodeIgniter Email Library</h1>';
$htmlContent .= '<p>You can attach the files in this email.</p>';

$config['mailtype'] = 'html';
$this->email->subject('Test Email (Attachment)');

Send Email to Multiple Recipient(s):

Using to() function of Email class, you can send email to single or multiple recipient(s). Provide single email, comma-delimited list or an array.





$recipientArr = array('''''');
