function hook_block_view_alter in MongoDB 7

Perform alterations to the content of a block.

This hook allows you to modify any data returned by hook_block_view().

Note that instead of hook_block_view_alter(), which is called for all blocks, you can also use hook_block_view_MODULE_DELTA_alter() to alter a specific block.

Parameters

array $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 default 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.

object $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().

  // provided by the "somemodule" module.
