hook_block_view_MODULE_DELTA_alter
function hook_block_view_MODULE_DELTA_alter
hook_block_view_MODULE_DELTA_alter(&$data, $block)
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: The data as returned from the hook_block_view() implementation of the module that defined the block. This could be an empty array or NULL value (if the block is empty) or an array containing:
- 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().

Code
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'); }
