modules/simplenews/README.txt

+
+DESCRIPTION
+-----------
+
+Simplenews publishes and sends newsletters to lists of subscribers. Both
+anonymous and authenticated users can opt-in to different mailing lists.
+HTML email can be sent by adding Mime mail module.
+
+
+REQUIREMENTS
+------------
+
+ * For large mailing lists, cron is required.
+ * HTML-format newsletters and/or newsletters with file attachments require the
+   mime mail or HMTL mail module.
+ * When sending newsletters on regular cron (cron.php), it is important that
+   the base url (settings.php, variable $base_url) is set correctly or links
+   inside the newsletter will not work. See the Tips (13.) below.
+ * Additionally when using Drush to start cron, it is important to use the
+   argument --uri=http://www.example.com
+
+
+INSTALLATION
+------------
+
+ 1. CREATE DIRECTORY
+
+    Create a new directory "simplenews" in the sites/all/modules directory and
+    place the entire contents of this simplenews folder in it.
+
+ 2. ENABLE THE MODULE
+
+    Enable the module on the Modules admin page.
+
+ 3. ACCESS PERMISSION
+
+    Grant the access at the Access control page:
+      People > Permissions.
+
+ 4. CONFIGURE SIMPLENEWS
+
+    Configure Simplenews on the Simplenews admin pages:
+      Configuration > Simplenews.
+
+    Enable new content types to use as newsletter:
+      Structure > edit content type > Publishing options
+
+    Add and configure newsletter categories:
+      Structure > Web Services > Newsletters > Add newsletter category
+      Structure > Web Services > Newsletters > edit newsletter category
+
+ 5. ENABLE SIMPLENEWS BLOCK
+
+    With the Simplenews block users can subscribe to a newsletter.
+
+    Enable a Simplenews block per Newsletter category:
+      Structure > Newsletters > edit newsletter category
+
+ 6. CONFIGURE SIMPLENEWS BLOCK
+
+    Configure the Simplenews block on the Block configuration page. You reach
+    this page from Block admin page (Structure > Blocks).
+    Click the 'Configure' link of the appropriate simplenews block.
+
+    Permission "subscribe to newsletters" is required to view the subscription
+    form in the simplenews block or to view the link to the subscription form.
+
+ 7. SIMPLENEWS BLOCK THEMING
+
+    More control over the content of simplenews blocks can be achieved using
+    the block theming. Theme your simplenews block by copying
+    simplenews-block.html.twig into your theme directory and edit the content.
+    The file is self documented listing all available variables.
+
+    The newsletter block can be themed generally and per newsletter:
+      simplenews-block.html.twig (for all newsletters)
+      simplenews-block.tpl--[tid].php (for newsletter series tid)
+
+ 8. MULTILINGUAL SUPPORT
+
+    Simplenews supports multilingual newsletters for node translation and url
+    path prefixes.
+
+    When translated newsletter issues are available subscribers receive the
+    newsletter in their preferred language (according to account setting).
+    Translation module is required for newsletter translation.
+
+    Path prefixes are added to footer message according to the subscribers
+    preferred language.
+
+    The preferred language of anonymous users is set based on the interface
+    language of the page they visit for subscription. Anonymous users can NOT
+    change their preferred language. Users with an account on the site will be
+    subscribed with the preferred language as set in their account settings.
+
+    The confirmation mails can be translated by enableding the Simplenews
+    variables at:
+      Home > Administration > Configuration > Regional and language > Multilingual settings > Variables
+    Afterwards, the mail subject and body can be entered for every enabled
+    language.
+
+9.  NEWSLETTER THEMING
+
+    You can customize the theming of newsletters. Copy the file
+    simplenews-newsletter-body.html.twig from the simplenews module directory
+    to your theme directory. Both general and by-newsletter theming can
+    be performed.
+
+      simplenews-newsletter-body.html.twig (for all newsletters)
+      simplenews-newsletter-body--[newsletter_id].html.twig
+      simplenews-newsletter-body--[view mode].html.twig
+      simplenews-newsletter-body--[newsletter_id]--[view mode].html.twig
+
+      [newsletter_id]: Machine readable name of the newsletter category
+      [view mode]: 'email-plain', 'email-html'
+      Example:
+        simplenews-newsletter-body--1--email-plain.html.twig
+
+    The template files are self documented listing all available variables.
+    Depending on how the mails are sent (e.g. how cron is triggered), either the
+    default or the admin theme might be used, if one has been configured.
+    To prevent this, Simplenews supports the mail theme setting from the
+    mailsystem module (http://drupal.org/project/mailsystem). Install it, choose
+    the mail theme and the newsletter templates from that theme will be used no
+    matter which other themes are enabled.
+
+    Using the fields Display settings each field of a simplenews newsletter can
+    be displayed or hidden in 'plain text', 'HTML' and 'HTML text alternative'
+    format. You find these settings at:
+      Structure > Content types > Manage display
+    Enable the view modes you want to configure and configure their display.
+
+10. SEND MAILING LISTS
+
+    Cron is required to send large mailing lists.
+    If you have a medium or large size mailing list (i.e. more than 500
+    subscribers) always use cron to send the newsletters.
+
+    To use cron:
+     * Check the 'Use cron to send newsletters' checkbox.
+     * Set the 'Cron throttle' to the number of newsletters send per cron run.
+       Too high values may lead to mail server overload or you may hit hosting
+       restrictions. Contact your host.
+
+    Don't use cron:
+     * Uncheck the 'Use cron to send newsletters' checkbox.
+       All newsletters will be sent immediately when saving the node. If not
+       all emails can be sent within the available php execution time, the
+       remainder will be sent by cron. Therefore ALWAYS enable cron.
+
+    These settings are found on the Newsletter Settings page under
+    'Send mail' options at:
+      Administer > Configuration > Web Services > Newsletters > Settings > Send mail.
+
+11. (UN)SUBSCRIBE CONFIRMATION
+
+    By default the unsubscribe link will direct the user to a confirmation page.
+    Upon confirmation the user is directed to the home page, where a message
+    will be displayed. On the Simplenews subscription admin page you can
+    specify an alternative destination page.
+      Structure > Configuration > Web Services > Newsletters > edit newsletter category > Subscription settings
+
+    To skip the confirmation page you can add parameters to the subscription
+    URL.
+      Example: [simplenews-subscribe-url]/ok
+    When an alternative destination page has been defined the extra parameters
+    will be added to the destination URL.
+      Example: [simplenews-subscriber:subscribe-url]/ok
+      Destination: node/123
+      Destination URL: node/123/ok
+
+ 12. ACCESS
+
+    Every newsletter has an 'access' setting that determines whether subscribe
+    and unsubscribe are available on newsletter forms.
+
+    Default: Any user with 'Subscribe to newsletters' permissions can subscribe
+      and unsubscribe.
+    Hidden: Subscription is mandatory or handled programmatically by adding
+      manual code.
+
+    Note that mandatory subscription is restricted by law in some countries.
+
+    Moreover, note that subscribers can be added to the spool of a newsletter
+    issue through "Recipient Handlers" (missing documentation - see code in
+    RecipientHandlerInterface and examples in the demo sub-module) even when
+    subscribers don't have a subscription to the newsletter type corresponding
+    to the issue. This can be useful for the newsletter types with access set
+    to 'hidden'. Note that manual recipient handling is separate from manual
+    subscription handling — these are two separate concepts!
+
+ 13. TIPS
+    A subscription page is available at: /newsletter/subscriptions
+
+    The Elysia Cron module (http://drupal.org/project/elysia_cron) can be used
+    to start the simplenews cron hook more often than others, so that newsletter
+    are sent faster without decreasing site performance due to long-running cron
+    hooks.
+
+    If your unsubscribe URL looks like:
+      http://newsletter/confirm/remove/8acd182182615t632
+    instead of:
+      http://www.example.com/newsletter/confirm/remove/8acd182182615t632
+    You should change the base URL in the settings.php file from
+      #  $base_url = 'http://www.example.com';  // NO trailing slash!
+    to
+      $base_url = 'http://www.example.com';  // NO trailing slash!
