Building a Multistep Registration Form in Drupal 7 using Ctools

This article provides a step-by-step tutorial for creating a custom, multistep registration form via the Ctools Form Wizard in Drupal 7. If you'd prefer to solely use the core Form API, take a look at Building a Multistep Registration Form in Drupal 7, a previous blog post. In the interest of saving time, I'm going to be lifting some text directly from that post, given that there are a number of overlapping tasks.

Why use the Chaos Tools module to build a multistep form? Well, Ctools offers a number of tools that build upon the core Form API, allowing you to create a multistep form faster. This includes providing a method for caching data in between steps, adding 'next' and 'back' buttons with associated callbacks, generating a form breadcrumb, etc.

Introducing Devit

Devit Admin
You have a live website and you need to copy a fresh version of the (live) database onto your local machine for development. Next, you need to run through one or more of these rote tasks:

  • Disable Drupal core caches (page cache, block cache, CSS & JS optimization, etc.)
  • Sanitize user data
  • Update Drupal's file system paths (public, private, tmp directories)
  • Enable email rerouting
  • Update logging and error level settings
  • Re-configure a contrib module. E.g., Secure Site (enable, set permissions, guest accounts).

Does this sound familiar? If so, I have good news! I've created a module that will help you automate that process.

Introducing Writer: A Drupal blogging theme for developers

Writer Theme
My friend and co-acquian, Bryan Braun, recently released a new, beautiful, minimalist blogging theme on Drupal.org called Writer. I'll let Bryan make the official introduction:

"The story is quite simple. I am a front-end developer who blogs. I searched the Drupal theme repository, but I was unable to find a blogging theme designed specifically for developers. So I made one.

This theme was designed using three driving principles:

  • Brutally simple design
  • Fantastic typography
  • Support for code snippets

These principles guided me through the tradeoffs and helped me make various design decisions. Let's get into the details..."

Field API - Creating your own field formatters

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:

  1. You're using the phone field to display phone numbers, but you'd like to customize the HTML output to make it mobile-compatible (click to call).
  2. Your nodes display full addresses via the addressfield module, but you'd like to render those addresses as google maps links.

Let's start at the beginning: you're going to be creating a custom module. Let's call is grasmash.module for vanity's (and sanity's?) sake.

We'll start by letting the Field API know that we have a new field format for it to play with.

Create a "password_reset" resource for Services

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.

Snippet Snack: Create Display Suite fields for Flag & Flag Count

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.

When added to a custom module, this snippet will provide Display Suite 'Flag this' and 'Flag Count' fields for each applicable Flag type.

Integrating FBOAuth with Services

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.

Among its many default resources, Services offers a user.login method that allows external applications to authenticate via Drupal. I'm going to share a quick snippet that will permit you to extend Services so that it allows your users to login via Facebook (leveraging the FBOauth module).

Start by downloading and enabling Services and Fboauth. Then, create a custom module to house your code. Your module's info file should specify services and fboauth as requirements.

Introducing the Unsubscribe module

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?

Now there's a simple way to let your users unsubscribe from any Drupal-originating email. Introducing the Unsubscribe module. This module provides a simple unsubscribe form, and an "unsubscribe from email communications" checkbox on the account settings page.
