hook_block_view_MODULE_DELTA_alter

Perform alterations to a specific block.

Modules can implement hook_block_view_MODULE_DELTA_alter() to modify a specific block, rather than implementing hook_block_view_alter().

Parameters

$data: An array of data, as returned from the hook_block_view() implementation of the module that defined the block:

• subject: The localized title of the block.
• content: Either a string or a renderable array representing the content of the block. You should check that the content is an array before trying to modify parts of the renderable structure.

$block: The block object, as loaded from the database, having the main properties:

• module: The name of the module that defined the block.
• delta: The unique identifier for the block within that module, as defined in hook_block_info().

function hook_block_view_MODULE_DELTA_alter(&$data, $block) {
  // This code will only run for a specific block. For example, if MODULE_DELTA
  // in the function definition above is set to "mymodule_somedelta", the code
  // will only run on the "somedelta" block provided by the "mymodule" module.

  // Change the title of the "somedelta" block provided by the "mymodule"
  // module.
  $data['subject'] = t('New title of the block');
