Module Description
The Previewable Email Template (PET) module lets you create email templates, with token substitution, which can be previewed by the user before sending. The emails can be sent to one or many email addresses in a flexible way, and the recipients may or may not be Drupal account holders (users).

PET stores templates in a db table, not the variables table, so there is none of the memory usage which goes with the latter.

PET templates are in one place for easy management by site administrators. Emails can be sent one of three ways:


* interactively, from a link
* programmatically, in response to any situation
* via a Rules action (D7 only)

README for D7 version Previewable Email Templates (PET) ================================= The Previewable Email Template (PET) module lets users create email templates, with token substitution, which can be previewed before sending. The emails can be sent to one or many email addresses in a flexible way, and the recipients may or may not be Drupal account holders (users). Individual email sends can be customized per email send without affecting the template, which makes one-off customization a breeze. PET puts all your email templates in one place which makes for easy editing by your users, who don't have to go into the bowels of Rules to edit an email. Emails can also be sent programmatically by you the developer. PET stores templates in a db table, not the variables table, so there is none of the memory usage which goes with the latter. PETs are based on the Entity API, which means export, import, clone, code-based defaults, etc are supported. PET supports the Rules module, so email actions can be triggered by any Rule. PET supports the MimeMail module for HTML emails. Required Modules ================ - Entity API Optional Modules ================ - Rules - MimeMail Installation ============ * Copy the pet directory to the modules folder in your installation. * Go to the Modules page (/admin/modules) and enable it. Template Management =================== Manage (import, add, edit, clone, delete, export) the templates for your site from the Structure page (/admin/structure/pets). Users must have "administer previewable email templates" permission for this. * Title (required) - A descriptive title for the template. For reference by PET administrators. Doesn't appear anywhere in the email itself. * Name (required) - Machine name for the template. This is used if you refer to your template from code. * Subject (required) - The email subject. May contain tokens for substitution. * Body (optional but obviously common) - The email body. Like Subject, may contain tokens. * From override (optional) - An alternative From address for emails originating from this template. If not provided the site default is used. * CC default (optional) - One or more emails to be cc'd on every email sent using this template. * BCC default (optional) - One or more emails to be blind cc'd on every email sent using this template. * Recipient callback (optional) - The name of a function which is called to retrieve a list of email recipients, if the uid argument is 0 (not missing, but the number 0) for an interactive send. This is a function that you provide. If there is a nid argument, the node is loaded and passed to this function. Using PET Templates =================== Once you've created a PET template, you can fire it a) interactively, b) via code you write, or c) via Rules. Interactive PETs ================ To send a PET interactively a user must have "use previewable email templates" permission. The best way to get a feel for the UI when sending when doing interactive sends is to create a template (/admin/structure/pets/add), then click the link of the PET Label at (/admin/structure/pets). A form will appear with the template data, and clicking the Preview button will show the email as it will be sent, along with token substitutions if any and markup. Clicking back allows edits to be made for this particular send, without changing the stored template itself. When happy with the preview, click Send email(s) to send the email. You the developer can include a link with the path "/pet/MY_PET_NAME" anywhere you like on your site to give your users interactive access to a template. Interactive PETs With Substitutions =================================== In this simple form of the path above, with no arguments provided, the user will be required to enter one or more email addresses. User token substitutions (if present in the template) will be made for every email that has a corresponding user in the site. Global token substitutions will also be made. You can provide a default user in the To field by including uid=[uid] in the query, e.g. /pet/MY_PET_NAME?uid=17 This will provide token substitution for user 17. Additional email recipients can also be added to the form. To invoke a PET for a custom list of users, specify "recipient_callback=true" in the query, for example /pet/MY_PET_NAME?recipient_callback=true If the PET is set up to support user token substitution then for each email with a corresponding drupal user the substitution will take place. To invoke a PET with node substitution, add the node id to the arguments, e.g. /pet/MY_PET_NAME?uid=17&nid=244 Token substitution will be done on both user 17 and node 244. Recipient callback could be used as well, as in /pet/MY_PET_NAME?recipient_callback=true&nid=244 For example, let's say you manage events in your site, and you wish to send an email to all registrants reminding them of the event date. The event info is stored in node 348 and you have a function called event_registrants($event) which, given an event node returns an array of registrant emails. Finally, the name of the PET template is "event_reminder". The following path would provide an interactive way to do this send: /pet/event_reminder?recipient_callback=true&nid=348 Firing PET Emails From Code =========================== PET emails can also be sent from code anywhere in your site. You can do this in response to whatever situation you have, and you have full control over the output. The authors of this module fire PETs programmatically in response to e-commerce purchases, class signups, event reminders, membership expirations, and many other triggering events. There are two functions available to programmers. See function pet_send_mail() for sending emails to multiple recipients. See function pet_send_one_mail() for sending email to a single recipient. These function headers contain further documentation. Additional tokens can be provided via hook_pet_substitutions_alter(). Triggering PET Emails From Rules ================================ If you have Rules enabled on your site (admin/config/workflow/rules) you will see the Rules action "Send PET mail" provided by the PET module. In the action you choose the PET template to fire, along with either a) a fixed set of email address(es) or a recipient user provided by the Rules event. You may also choose a node for token substitutions. MimeMail Integration ==================== For those wanting to send HTML email, PET supports the MimeMail module. When MimeMail is enabled, you will see additional options in the template edit form, including a plain text email body, and a checkbox for sending plain text only. If you leave the plain text body empty, MimeMail will perform its usual conversion of markup to plain text using core's drupal_html_to_text(). If you provide a plain text version of the email, it will be included in the multipart mime email. MimeMail also works for programmatic and Rules triggered sends.
