In 1972, a crack web development team was sent to prison by a military court for a module they didn't commit. These men promptly escaped from a maximum security stockade to the php underground. Today, still wanted by the community, they survive as soldiers of fortune.

If you have a problem, if no other module can help, and if you can understand it, maybe you can use...

Rules for Fools

I love it when a rule

comes together

● Rules consist of Events, Conditions and Actions● Simply it looks for an event● When that event happens (under certain

conditions)● It fires off an action

What is the rules module?

● Events are linked to things happening on your site● Comment (viewed, created, deleted)● Node (viewed, updated, created)● System (cron, bootstrapped)● Taxonomy (create term/vocabulary)● User (log in/out, created, updated)● Extended by other modules (Profile, Feeds etc)

What is an event?

● Conditions check what the specifications of the event are

● Data (comparison, empty)● Entity (field exists)● Content (load all fields)● Path (check path)● User (check role)

What is a condition?

● Do something● Data (add variable, set value)● Entity (create entity, fetch entity)● Node (publish content, make sticky)● System (redirect, send email, set message)● User (add role)

What is an Action?

DrupalCausality

Because this EVENT happened,

under these conditions, this

action will take place.

● Choosing the data you want to interact with● Direct input mode

– Using tokens● [site:current-date]● [site:current-user]● [node:title]● [node:nid]

● Data selection mode– Interactive browse through tokens

The data selector

● A set of rules/actions● To be used either by Rules or other modules● Views Bulk Operations● Drupal Commerce

What are components?

● Set your rules to be activated based on time● Set nodes to be unpublished 2 weeks after

publishing● Disallow comments 1 year after publish date

What is scheduling rules?

● Do the action for multiple items● Send email to all users● Unpublish referenced items

What are looping actions?
