Drupal 7's Field API is amazing—it allows us to easily add fields to any type of entity, and customize those fields with various widgets and display formats. I'm going to walk you through two examples of how you can leverage the Field API to create your own custom field formats.

Example use cases:

Just another quick snippet to add to the Grasmash Services archive.

This will allow you to POST an email address to /your_endpoint/user/password_reset and trigger a 'Forgot Password' email to be sent to the appropriate user.

I've decided to make a new home for the small snippets that I post periodically: Snippet Snacks. This will be small repository for useful Drupal snippets.

Here's the first one—a snippet that forms a bridge between Display Suite and Flag.

Just a quick snippet!

Dropping this in a custom module will allow you to easily index values from the Flag module's {flag_count} table in a Search API Solr index.

This is mostly a note to myself. When calling the user.register method for the Services module, the JSON data format is a little wonky:

Everyone loves the Services module. It allows you to easily create API endpoints for Drupal's core features, permitting you to interact with Drupal from external applications. It also very easily extended.

I recently began sending out mass emails via Drupal, and I was surprised to find that no universal solution existed for providing an "unsubscribe" link on Drupal emails. Sure, you can use Subscriptions to manage actual subscriptions to content, or Notifications for activity notification preferences, but what if you just want to unsubscribe from email communication in general? What if your Drupal admins periodically send out mass emails manually, and you'd like to unsubscribe from even those?

Embedding a view programmatically is not too difficult, but what about passing it a value for an exposed filter? This snippet gives a simple example of how to modify the View object in a more meaningful way before rendering it.

<?php
$name = 'my_view';
$display = 'block_1';
$view = views_get_view($name);
$view->set_display($display);
?>

If you'd like to pass in exposed filter values, define these properties before calling $view->preview():

If you find that, after SSHing to a remote linux server, the command line readout is not in English, you can easily set the language for your particular user.

Enter the following line in ~/.bash_profile:
export LANG=en_US.iso88591

After saving, reload the file:
source ~/.bash_profile

Hope that helps someone! I'm sure I'll be referencing this page in the future.
