Extended block visibility

This module extends Drupal's block visibility settings, for ease of configuration and deployment.

Features

• Allows PHP block visibility to be defined in code.
• Allows theme specific block visibility code.
• Removes reliance on core php module and eval() for defining block visibility.

Usage

1. Edit a block.
2. Pick one or more of the applicable callback functions from the list provided.
3. Implement the functions as follows:

/**
 * Block visibility callback for the search form block.
 *
 * @param object $block
 *   The block object.
 *
 * @return bool
 *   TRUE if the block should be displayed on the current page.
 */
function _search_form_block_visibility($block) {
  if ($block->theme == 'my_theme') {
    return !drupal_is_front_page();
  }
  return arg(0) == 'node' && is_numeric(arg(1));
}

Note that if multiple callbacks have been implemented for a block, the most specific match will always be used.

Possible extensions

• Allow users to specify their own function names for each block.
• Create a hook which can be implemented by one or more modules to determine block visibility (similar to hook_file_download()).
• Create an info hook which can be used to specify callback names and override other block visibility settings, including user roles.

Similar projects

• Features Extra: Allows exporting of block visibility settings for deployment, but still requires eval() and php code entry through the admin interface.
• Block Page Visibility: Allows visibility options to be defined through a hook (D5/D6 only). This module provides similar functionality to hook_block_info() in Drupal 7 and doesn't provide php-based visibility.
