This is an example of how to send an email from a component. You would typically put this into your components controller.

Contents

Fetch the mail object

A reference to the global mail object (JMail) is fetched through the JFactory object. This is the object creating our mail.

$mailer =& JFactory::getMailer();

Set a sender

The sender of an email is set with setSender. The function takes an array with an email address and a name as an argument. We fetch the sites email address and name from the global configuration. These are set in the administration back-end (Global Configuration -> Server -> Mail Settings).

$config =& JFactory::getConfig();
$sender = array( 
    $config->getValue( 'config.mailfrom' ),
    $config->getValue( 'config.fromname' ) );
 
$mailer->setSender($sender);

Recipient

You set the recipient of an email with the function addRecipient. To set the email address to the currently logged in user, we fetch it from the user object.

$user =& JFactory::getUser();
$recipient = $user->email;
 
$mailer->addRecipient($recipient);

If we had multiple recipients we would put each recipients email address in an array.

$recipient = array( 'person1@domain.com', 'person2@domain.com', 'person3@domain.com' );
 
$mailer->addRecipient($recipient);

Create the mail

We need to set a subject line and create the text body. The subject is set with setSubject.

The easy way to create an email body is as a string with plain text. Use the function setBody to add a message to the mail body. You can also attach a file with addAttachment. It takes a single file name or an array of file names as argument.

$body   = "Your body string\nin double quotes if you want to parse the \nnewlines etc";
$mailer->setSubject('Your subject string');
$mailer->setBody($body);
// Optional file attached
$mailer->addAttachment(JPATH_COMPONENT.DS.'assets'.DS.'document.pdf');

If you prefer to format your email in HTML, you need to tell the mailer it is HTML. This is done with IsHTML. When sending HTML emails you should normally set the Encoding to base64 in order to avoid unwanted characters in the output. The subject line and any attachments are handled as above, with the exception of images embedded in the HTML. These are taken care of with the function AddEmbeddedImage.

$body   = '<h2>Our mail</h2>'
    . '<div>A message to our dear readers'
    . '<img src="cid:logo_id" alt="logo"/></div>';
$mailer->isHTML(true);
$mailer->Encoding = 'base64';
$mailer->setBody($body);
// Optionally add embedded image
$mailer->AddEmbeddedImage( JPATH_COMPONENT.DS.'assets'.DS.'logo128.jpg', 'logo_id', 'logo.jpg', 'base64', 'image/jpeg' );

Normally you would leave any images on your server and refer to them with an ordinary HTML image tag, to reduce size of the mail and the time sending it.

Sending the mail

The mail is sent with the function Send. It returns true on success or a JError object.

$send =& $mailer->Send();
if ( $send !== true ) {
    echo 'Error sending email: ' . $send->message;
} else {
    echo 'Mail sent';
}

You would probably want to write your own error handler, if there is an error sending the mail.

The JMail object is used for sending mail in Joomlas contact manager. See the file joomla/components/com_contact/controller.php
