About

This extension provides an email templating service and mail queue functionality for all your TYPO3 extensions. It also supports Templates in various languages, which can be managed in the backend.

Additionally sg_mail comes with multiple features that help to integrate with ext:form.

sg_mail ist multi-site and multi-language ready.

Usage

Registering your Extension

To register your extension with sg_mail, you need a Configuration File for each template you want to integrate. It needs be a .php file and has to be inside the Configuration folder typo3conf/ext/{your_extension}/Configuration/Sgmail of your extension.

Additionally you need to make your registration file known in your ext_localconf.php file:

// register mail templates
$GLOBALS['sg_mail']['my_extension_key']['unique_template_name'] = \TYPO3\CMS\Core\Utility\ExtensionManagementUtility::extPath('my_extension_key') . '/Configuration/SgMail/MyTemplate.php';

sg_mail will automatically parse valid configuration files of all extensions within your TYPO3 instance.

Inside the file you have mandatory and optional settings you can define:

Mandatory

• extension_key Needed to associate this template with the appropriate extension,

• template_key A unique identifier of your template.

• description A short description of your templates usage, displayed in the backend template editor. This should be a language label

• subject The default mail subject used for this Template. Here you can also provide a language label.

• markers An array of placeholder variables. Are dynamically replaced by the appropriate values. If you don't want any markers, provide an empty array.

A marker needs to be structured as follows:

• marker The variables name used in your templates.

• type Here you can specify the variable type by using one of the constants in the \SGalinski\SgMail\Service\MailTemplateService class.

• value An example value of this marker. Also used for previewing your mails in the backend module.

• description A short text describing the purpose of this marker.

Optional

• template_path You can provide a path to your mail template that differs from the default path with this setting.

The template folder If not overwritten in your configuration file, the default location for your extensions templates is ext/sg_example/Resources/Private/Templates/SgMail/{TemplateNameInUpperCamelCase}. Inside this folder you need a folder for every template you want to register. The name of the template file itself should be template.html

Example:

Your configuration file for the template "confirm_mail" should be located at ../Configuration/ConfirmMail.php.

A possible ConfirmMail.php file could look like this:

return [
	'extension_key' => 'sg_example',
	'template_key' => 'confirm_mail',
	'description' => 'LLL:EXT:sg_example/Resources/Private/Language/locallang.xlf:mail.confirm.description',
	'subject' => 'LLL:EXT:sg_example/Resources/Private/Language/locallang.xlf:mail.confirm.subject',
	'markers' => [
		[
			'marker' => 'username',
			'type' => \SGalinski\SgMail\Service\MailTemplateService::MARKER_TYPE_STRING,
			'value' => 'max.mustermann@example.org',
			'description' => 'LLL:EXT:sg_energieportal/Resources/Private/Language/locallang.xlf:mail.marker.username'
		],
		.... // more markers
	]
];

The default path to the template.html file: ext/sg_example/Resources/Private/Templates/SgMail/ConfirmMail

Send an email with the MailTemplateService

Basic Usage:

1. Get an instance of MailTemplateService
2. Provide the template_name, extension_key and marker array in the constructor
3. Set or override all desired fields (i.e. setLanguage, setToAddresses, setTemplateName, setExtensionKey etc.)
4. Invoke the sendEmail() function

Example:

// get an instance of the service
/** @var MailTemplateService $mailService */
$mailService = $this->objectManager->get(MailTemplateService::class, 'confirm_mail', 'sg_example', ['username' => $username]);

$mailService->setFromName($this->settings['fromName']);
$mailService->setFromAddress($this->settings['fromEmail']);
$mailService->setToAddresses([$emailAddress]);
$mailService->setIgnoreMailQueue(TRUE);

// set the pageId (mandatory since version 4.0!!!)
$mailService->setPid(123);

// set the proper language for the mail (not necessary if you want the default language)
$mailService->setLanguage($GLOBALS['TSFE']->config['config']['language']);

// finally send the mail
$mailService->sendEmail();

The mail queue

The mail queue holds all the mails that have been sent or should be sent in the future. You can view the mail queue in the backend module and interact with the entries.

You can set the priority (setPriority function of the service) for your mails with the constants of the SGalinski\SgMail\Domain\Model\Mail class. With the Flag ignoreMailQueue you can switch between queueing your Mail(false) or immediately(true) sending it.

• PRIORITY_LOWEST
• PRIORITY_LOW
• PRIORITY_MEDIUM
• PRIORITY_HIGH
• PRIORITY_HIGHEST

The higher the priority, the more likely the mail will get send immediately (depending how "busy" the MailQueue is).

The command controller

To enable the mail queue functionality you need to configure the SendMailCommandController.

Go to your scheduler module in the TYPO3 Backend and setup a scheduled CommandController task. Chose the SgMail SendMail:runSendMail CommandController command and supply a frequency in seconds or cron format.

For more information on the TYPO3 scheduler extension read its manual.

Language handling

When you provide no language to the MailService API, the default language of the TYPO3 instance is used. This happens also if the given iso code of the language is not known (inside the sys_lang table).

In your template editor you have automatically all languages of your page shown.

Example

finishers {
	1 {
		class = SGalinski\SgMail\Service\FormhandlerFinisherService
		config {
			checkBinaryCrLf = message
			template_key = your_template
			extension_key = extension_key
			to_address = admin@sgalinski.de
			from_address = info@sgalinski.de
			from_name = sgalinski.de
			ignore_mail_queue = TRUE
		}
	}
}

The Backend Module

With this extension comes a new module in the "WEB" section of your TYPO3 Backend.

Clicking on it loads the administration panel for all your mail templates and the mailing queue.

The module provides two modes:

In the Template Editor mode you see an overview of all the template markers for the selected template. Here you can edit & reset your templates in all the languages of your TYPO3 instance. Additionally you can test your mails by entering an email address and clicking Send Test Mail.

With the Mail Queue mode, you can see the current content of your mailing queue. For each queue entry you have the following options:

Edit
Disable/Enable
Delete
Show further information
Show history
.... Expand/Collapse the options menu
Send the mail again (if already sent)
Send this mail (if not already sent)
View the content of this mail

Additionally you can now filter the mail queue or export it to a csv file.

Blacklisting templates

It is possible to exlude certain templates for all or specific domains. Excluded templates are not shown in the backend module and their mails are never send. Mails from these templates are still logged and you can search for them in the backend module.

Blacklisting templates for all domains

In the extension configuration setting general.excludeTemplatesAllDomains, you can specify which templates should be excluded for all domains with a comma seperated list.

Example:

sg_comments.approved, sg_comments.declined

The templates "approved" and "declined" of the extension sg_comments are blacklisted for every domain.

Blacklisting templates for certain domains

In the extension configuration setting general.excludeTemplates, ou can specify which templates should be excluded for which domains with a Semicolon separated list of comma separated list.

The comma seperated lists contain the page id and the templates to be excluded.

Example:

1, sg_comments.approved, sg_example.welcome;10, sg_comments.declined

The template "approved" of the extension sg_comments and the template "welcome" of the extension sg_example are blacklisted for the domain with the page id 1.

The template "declied" of the extension sg_comments is blacklisted for the domain with the page id 10.

If the page ids are missing or not correspond to a site root, the configuration has simply no effect.

Searching for emails from blacklisted templates

In the backend module mode "Queue" you can filter for "Blacklisted" mails. Note: you shouldn't select a template filter to see the blacklisted mails.

Developer Guide

Database and Models

This extension uses two database tables:

• tx_sgmail_domain_model_template

  Stores all template settings that have been provided via the backend module. The Default settings exist only in the register array and not in the database.

• tx_sgmail_domain_model_mail

  This table holds all the mails in the mailing queue. When they are sent, the flag sent is set to true and the sending_time is inserted. You can inspect the mailing queue with the backend module. If an email should ignore the mail queue, it is still inserted in this table with the sent flag set to true.

The extbase model classes for these tables are located at the Domain\Model folder.

Service Classes

MailTemplateService

This class provides you with an API to the mailing functionality and various helper functions regarding the your templates.

Here is an overview of some important functions:

function getDefaultTemplateMarker

Reads custom example template marker from your locallang.xlf. This is only useful if you need multi language examples in your Backend Marker

function loadPredefinedValuesForTemplate

Sets the predefined values for this template that have been supplied by the editor. Use this method if you have no custom values for cc, bcc, replyTo, fromMail and fromName. Returns false if the template & extension key combination was not found.

function sendEmail

Sends your mail or adds it to the mailing queue, depending on the settings. You can specify in with the boolean parameter if the preview values should be used or not.

function sendMailFromQueue

Forces the sending of an E-Mail from within the queue. If it has already been sent, it gets send again.

function getMailMessage

You can get the instance of \TYPO3\CMS\Core\Mail\MailMessage that is internally used by the service, if you want a more direct interaction with the mail object.

functions setX

Sets the various variables to the supplied values. With these functions you can overwrite for instance from/cc/bcc Adresses, from name etc.

You can also tell the MailTemplateService to not ignore this mail when adding to the mailing queue: function setIgnoreMailQueue.

Ext:form Integration

Template marker

This extension provides you the possibility to customize the identifier of the form input fields. These identifiers are used in the mail templates as marker names. To change a fields identifier, select it in the form editor and enter your desired identifier in the field labeled "Email template marker name". After saving the form, the change identifier name will be overwritten.

New mail finisher

sg_mail comes with two new finisher for your forms with the following settings regarding sg_mail integration:

• Template key: If this field is empty, a unique template name will be generated and automatically inserted into the field, after the form definition has been saved. The generated template name is based on the form identifier, concatenated with the finisher identifier (separated by -).
• Automatic Registration: A sg_mail registration will automatically be created. See the Automatic Registration section for more information
• Ignore Mail Queue: Mails will get send immediately and not added to the mail queue

Automatic Registration

If you select to automatically register your forms with sg_mail, the default html template for the emails will be used.

You can customize the TypoScript settings in the setup.ts in order to have control over automatically generated registration files:

# extension where automatic generated registrations are put. Will be appended with /Configuration/MailTemplates/. Make sure these folders exist!
configurationLocation = your_extension_key

# default html template file, which serves as a fallback for all mail templates
defaultHtmlTemplate = EXT:project_theme/Configuration/MailTemplates/Default.html

TypoScriptSettingsService

This Service enables you to access your typoscript settings outside of your controller classes. You simply need to supply your page id and the extension key. If you have no page id specific settings, set the page id to 0.
