How to get In-Field Labels in Drupal 7

Compact forms are always good to have and in-field labels is one of the feature that makes the form more compact and sleak. Conventionally the labels are set as "above" or "in-line" with the fields where as in-field labels are set with in the Label's respective fields. Technically form item or element fields are overlaid with their repective labels.

Optimizing/Caching Poll's Block

We all know that Poll is a core module which ships with Drupal. After installing this module we can setup poll and we can place a "most recent poll" block any where in region, usually its on a front page. I investigated this module and I found that it takes 20-25 queries to load most recent poll block and when a user submits a vote on that poll it does a cache_clear_all. Which was like WOW, in addition to submitting a vote users were also clearing my cached data. Optimizing or Caching poll's block for any kind of user (authenticated or anonymous) is like piece of cake, but figuring out how to do it was really a big pain in a neck.

Advanced Workflow Management

Advance Workflow Management will help workflow admin define single workflow with states adding a layer of groups at top of that; access control will be based on groups. This module will create a new tab "Workflow Groups" through which admins can create various roles as workflow groups, assign group role to the user (author/editor/publishers) along with the role that manipulate workflow.

Index additional information using node_api hook

I was going through one of my projects and I came to know that how simple it is to insert additional information into your site's search indexes using hook_nodeapi. A comprehensive details about hook_nodeapi can be found here.

Following are the steps involved to make this happen:

  • Create a module that implements hook_nodeapi, lets say example_nodeapi()

function example_nodeapi($node, $op) {
  // Function definition here
}
