|

* <li> title: A safe, translated string to use as the title for the progress page. Defaults to t('Processing').
|
||||
* <li> init_message: Message displayed while the processing is initialized. Defaults to t('Initializing.').
|
||||
* <li> progress_message: Message displayed while processing the batch. Available placeholders are %current% and %total%.
|
||||
* <li> error_message: Message displayed if an error occurred while processing the batch. Defaults to t('An error has occurred.').
|
||||
* <li> finished: Name of an implementation of callback_batch_finished(). This is executed after the batch has completed. This should be used to perform any result massaging that may be needed, and possibly save data in $_SESSION for display after final page redirection.
|

*

* The following keys are provided :
|
||||
* 'results' (read / write): The array of results gathered so far by
|
||||
* the batch processing, for the current operation to append its own.
|
||||
* 'message' (write): A text message displayed in the progress page.
|
||||
* The following keys allow for multi-step operations :
|
||||
* 'sandbox' (read / write): An array that can be freely used to
|
||||
* store persistent data between iterations. It is recommended to
|
||||
* use this instead of $_SESSION, which is unsafe if the user
|
||||
* continues browsing in a separate window while the batch is processing.
|
||||
* 'finished' (write): A float number between 0 and 1 informing
|
||||
* the processing engine of the completion level for the operation.
|
||||
* 1 (or no value explicitly set) means the operation is finished
|
||||
* and the batch processing can continue to the next operation.
