Save the configuration options from hook_block_configure().
This hook allows you to save the block-specific configuration settings defined within your hook_block_configure().
$delta: Which block is being configured. This is a unique identifier for the block within the module, defined in hook_block_info().
$edit: The submitted form data from the configuration form.
For a detailed usage example, see block_example.module.
Note: this list is generated by pattern matching, so it may include some functions that are not actually implementations of this hook.
function hook_block_save($delta = '', $edit = array()) {
// This example comes from node.module.
if ($delta == 'recent') {
variable_set('node_recent_block_count', $edit['node_recent_block_count']);
}
