CakePHP Email Queue plugin

This plugin provides an interface for creating emails on the fly and store them in a queue to be processed later by an offline worker using a cakephp shell command.

It also contains a handy shell for previewing queued emails, a very handy tool for modifying email templates and watching the result.

Requirements

• CakePHP 4.x

Installation

The plugin uses Debug email transport, so make sure your email config contain it:

Enable plugin

Load required database table

In order to use this plugin, you need to create a database table. Required SQL is located at

# config/Schema/email_queue.sql

Just load it into your database. You are free to change the file to use an integer primary key instead of UUIDs.

Or run migrations command:

bin/cake migrations migrate --plugin EmailQueue

Usage

Whenever you need to send an email, use the EmailQueue model to create and queue a new one by storing the correct data:

use EmailQueue\EmailQueue;
EmailQueue::enqueue($to, $data, $options);

enqueue method receives 3 arguments:

• First argument is a string or array of email addresses that will be treated as recipients.
• Second arguments is an array of view variables to be passed to the email template
• Third arguments is an array of options, possible options are
  • subject: Email's subject
  • send_at: date time sting representing the time this email should be sent at (in UTC)
  • template: the name of the element to use as template for the email message. (maximum supported length is 100 chars)
  • layout: the name of the layout to be used to wrap email message
  • format: Type of template to use (html, text or both)
  • headers: A key-value list of headers to send in the email
  • theme: The View Theme to find the email templates
  • config: the name of the email config to be used for sending
  • from_name: String with from name. Must be supplied together with from_email.
  • from_email: String with from email. Must be supplied together with from_name.

Previewing emails

It is possible to preview emails that are still in the queue, this is very handy during development to check if the rendered email looks at it should; no need to queue the email again, just make the changes to the template and run the preview again:

# bin/cake EmailQueue.preview

Sending emails

Emails should be sent using bundled Sender command, use -h modifier to read available options

# bin/cake EmailQueue.sender -h

You can configure this command to be run under a cron or any other tool you wish to use.
