January 20, 2012 - 7:32pm — brad

Gitolite gives you finely grained access permission control for multi-user and multi-repo Git installations. To reduce future complexity and increase automation options, I've changed the gitolite.conf to accept multiple sub-conf files.

A friend of mine is writing an iOS application which will communicate with a web server. He needed a basic JSON program to test out his code, so I wrote him this:

Cleanest/simplest method to render image fields with Drupal 7

September 26, 2011 - 6:40pm — brad

A common issue when building a site in Drupal: you've got a $node, $vars['node'], or $form_state['node'] and need to render an image (with image style) from one of the fields. I am building a custom form in this instance, and need to show the first image stored in some loaded nodes.

  // Get the node loaded via node_load into $node.

Field tokens are effectively available in Drupal 7

August 18, 2011 - 11:32am — brad

Update: Dave Reid just added basic field token support to Token. Try the beta4 of Token (http://drupal.org/project/token) before Entity Tokens. I worked out what needed to happen a few weeks ago, and finally wrote it up. I didn't realize there was an update the Token when I posted. Haha! Internet moves quick!

Get the renderable array for a single field instance

August 17, 2011 - 3:02pm — brad

I'm building an interface to simplify the user experience during content creation.

To create this new form, I need fields from the content types and user profile. Given a content type, field name, and field instance, this is the code you need to get the Form API renderable array for the field.

Normally I work in Windows or Linux. Currently, I am working on an iMac. Rather than fighting years of muscle memory, I switched the Command and Control keys in the Keyboard preferences. Problem is now Control keys in iTerm don't work. After some research I determined how to send Control characters with both Command and Control.
Note: I know this could use some screenshots. No time right now.
Here is how to make Control-C work in iTerm when Control/Command have been switched:

Render/embed a Panels Page in a jQuery Dialog Box

May 16, 2011 - 5:55pm — brad

I need a page on my Drupal 7 project site to display within a jQuery modal dialog box. Adding content to a jQuery dialog is straightforward with the Dialog module. The issue was the dialog box needed to contain the contents of a Panel. Previously I've embeded Views using views_embed_view(), but I've never tried to embed a Panel. A web search wouldn't give me a quick answer, so I worked it out.
