I've worked recently on some new features for my contrib module Block Inject and I thought I'd share with you what's new.

Based on some feature requests from the community, I've implemented two new things that make this module more flexible. They are available in the 7.x-1.2alpha5 release onwards.

Theming

First, the injected region is now wrapped in a <div> with some default classes on it for easy styling. I've also created an alter hook for this so you can add easily your own classes there depending on the $node object the region is injected in.

An example implementation of this hook:

function hook_block_inject_attributes_alter($attributes) {
  if ($attributes['node']->type == 'article') {
    $attributes['attributes']['class'][] = 'article-block-inject';
  }
}

The $attributes parameter is an array with two values: the node object and another attributes array that gets transformed into HTML attributes by the drupal_attributes() function.

Site building

The second new feature of the module is the possibility to specify default paragraph offsets for an inject region depending on some conditions related to the node body field.

For example, when creating the inject region you can set it so that the region gets injected 5 paragraphs lower than the middle if the total number of paragraphs is over 20. Or move the region higher by 2 paragraphs if the total number of paragraphs equals 6.

Feel free to check it out and let me know what you think.
