Build a Mobile App to Geo Locate Nearby Places with Drupal

In this tutorial (for DrupalCamp Ohio 2014) we'll explore how to build a mobile application and website that can geo locate places near our current position. The nearby location results will be displayed on a map, and will allow us to click on a result item to view its complete details.

The website will be powered by Drupal 7. The mobile application will be built using DrupalGap, which is powered by PhoneGap and jQuery Mobile. Let's get started!

Drupal User Entity Reference Field with Custom Autocomplete that uses an Address Field

User reference fields (aka entity reference fields) are great. As you may have guessed, we can use these fields to reference users on other entities (e.g. nodes).

Say we had a user reference field on the Article content type... by default, when selecting a user to reference, we could configure the field widget to be an autocomplete. This allows us to begin typing the user's login name as a way to reference them. This works well in most cases.

What if we had an address field on our user entities, and collected the user's first and last names? It may be more usable for site administrators to be able to search across the user's actual name instead of their user name for logging in.

We can use hook_menu(), hook_form_BASE_FORM_ID_alter(), and a custom callback function to provide a custom autocomplete widget that searches across our address field's values instead...
