Emails templates for each locale are stored in an XML file called dbscripts/xml/data/locale/[localeName]/email_templates_data.xml. Each email has an identifier (called email_key in the XML file) such as SUBMISSION_ACK. This identifier is used in the PHP code to retrieve a particular email template, including body text and subject.
The following code retrieves and sends the SUBMISSION_ACK email, which is sent to authors as an acknowledgment when they complete a submission. (This snippet assumes that the current article ID is stored in $articleId.)
Example 3.1. Example Code to Send a SUBMISSION_ACK Email
// Fetch the article object using the article DAO.
$articleDao = &DAORegistry::getDAO('ArticleDAO');
$article = &$articleDao->getArticle($articleId);
// Load the required ArticleMailTemplate class
import('mail.ArticleMailTemplate');
// Retrieve the mail template by name.
$mail = &new ArticleMailTemplate($article, 'SUBMISSION_ACK');
if ($mail->isEnabled()) {
// Get the current user object and assign them as the recipient of this message.
$user = &Request::getUser();
$mail->addRecipient($user->getEmail(),
$user->getFullName());
// Get the current journal object.
$journal = &Request::getJournal();
// This template contains variable names of the form {$variableName} that need to
// be replaced with the appropriate values. Note that while the syntax is similar
// to that used by Smarty templates, email templates are not Smarty templates. Only
// direct variable replacement is supported.
$mail->assignParams(array(
'authorName' => $user->getFullName(),
'authorUsername' => $user->getUsername(),
'editorialContactSignature' => $journal->getSetting('contactName') .
"\n" . $journal->getTitle(),
'submissionUrl' => Request::getPageUrl() .
'/author/submission/' . $article->getArticleId()
));
$mail->send();
}
