Join Jon Peck for an in-depth discussion in this video Creating a block, part of Drupal 7: Custom Module Development.
A Drupal block is an area which displays content whose position is controlled by the theme …and administrative block settings. …I'm going to programmatically create a block that shows a map of wind farms that are within …100 miles of the center specified. …To help us some of the computation I'm going to leverage a library that is within the location module. …There is no need to actually enable the location module to do this, but it does need to be there. …Open windfarms.module and scroll to the end. …Two functions are needed to generate a block and I will use a third to keep the code tidy.…
The first function that's needed is an implementation of hook_block_info. …By implementing this hook, I can declare to Drupal that a block with a particular machine …name and human readable administrative name exists. …Start with a docblock, Implements hook_block_info. …Hook_block_info requires no parameters and returns a nested array, function windfarms_block_info, blocks = array.…
Hook_block_info requires no parameters and returns a nested array. …

Q: gmap3_tools is not working the way I expected it to. What version of gmap3_tools should I be using?
A: Use the free exercise file containing the version of gmap3_tools used for recording; the published version of the module on drupal.org has changed since recording and is not backwards compatible.
Q: I attempted to run the Drupal site root from the project files, but the site isn't loading. Why not?
A: The Drupal configuration file in sites/default/settings.php contains database configuration specific to the environment used to record the movie. This may be different than your environment. Edit the file and search for "windfarms" - you may need to change the database host, username, password, db name and port to match your specific environment.
