The annotation form as it appears on a Drupal web page What will happen when we click the Update button? Nothing, because we haven’t written any code to do anything with the form contents yet. Let’s add that now. But before we do, we have to think about where we’re going to store the data that the user enters. Storing Data in a Database Table The most common approach for storing data used by a module is to create a separate database table for the module’s data. That keeps the data separate from the Drupal core tables.

Php file is parsed via include_once(), and any variable or string overrides established there are applied. php for details. Early Page Cache In situations requiring a high level of scalability, a caching system may need to be invoked before a database connection is even attempted. The early page cache phase lets you include (with include()) a PHP file containing a function called page_cache_ fastpath(), which takes over and returns content to the browser. The early page cache is enabled by setting the page_cache_fastpath variable to TRUE, and the file to be included is defined by setting the cache_inc variable to the file’s path.

When deciding what fields to create for your module, you should ask yourself: What data needs to be stored? If I make a query against this table, what fields and indices would I need? And finally, what future plans do I have for my module? The data we need to store are simply the text of the annotation, the numeric ID of the node it applies to, and the user ID of the user who wrote the annotation. It might also be useful to save a timestamp, so we could show a list of recently updated annotations ordered by timestamp.
