SilverStripe Permamail

====================== This module adds several enhancements to the core Email class in SilverStripe:

• Persisting sent emails in the database
• Allowing "resend" of emails
• Providing user-defined HTML templates for emails
• Send test emails, populated with your specific variables
• Send emails to a DataList of Members

Installation

composer require unclecheese/silverstripe-permamail:dev-master

Requirements

• SilverStripe 3.1.*
• unclecheese/reflection-templates
• unclecheese/gridfield-betterbuttons:1.2.*

Usage

By default, Permamail is injected as the class for Email, meaning Email::create() will instantiate a Permamail object instead of Email. Because Permamail is a subclass of Email, the API is exactly the same.

If you would like to use Permamail on a case-by-case basis, simply use new Permamail() and new Email() where you see fit, or override the injector setting in the configuration so that Email is the class used for Email.

Example

The API is exactly the same, with only two new methods:

• toMembers() accepts an array or SS_List of Member objects and uses their Email properties, sending an email to each one.
• setUserTemplate() accepts a string as the identifier of a user-defined template in the CMS. More information in the "Administration" section below.

The admin interface

Permamail provides a new ModelAdmin interface called Email, which provides two tabs:

Outbound Emails

Shows a list of all emails sent. Offers an option to resend.

Email templates

Allows creation of user-defined templates, with default subjects and "From" addresses.

Sending test emails

Every user-defined template can send a test email, and populate the template with the variables you have specified. To do this, the template uses the ReflectionTemplate class to gather all the variables and blocks in the template, and offers you the opportunity to customise what values are assigned to those variables. Options include:

• A static value (e.g. hardcoded)
• A random object from the database of a given ClassName
• A specific object from the database of a given ClassName

Querying specific records to inject into your template

To run a custom query, you can use a query string like an array is used in the filter() method of the ORM, for example: Category=gardening&Title:StartsWith=A&Created:LessThan=2014-11-11

Questions you may have

What if I'm using a custom mailer, like Mandrill, or SendGrid?

No worries. This module doesn't override the mailer. It just overrides the Email class that wraps the Mailer.

What about when the error logger sends out emails. I don't want to persist those to the database.

The error logger does not use the Email class unless you're unit testing. True errors are sent via simple PHP mail().

Won't this pollute the database? My site sends a lot of email.

For maintenance, use the PermamailCleanupTask. It accepts two parameters:

• unit: the unit of time to go back
• count: the number of units to go back

/dev/tasks/PermamailCleanupTask?count=30&unit=days will remove all emails that are more than 30 days old.
