function ajax_example_progressbar_progress

Get the progress bar execution status, as JSON.

This is the menu handler for examples/ajax_example/progressbar/progress/$time.

This function is our wholly arbitrary job that we're checking the status for. In this case, we're reading a system variable that is being updated by ajax_example_progressbar_callback().

We set up the AJAX progress bar to check the status every second, so this will execute about once every second.

The progress bar JavaScript accepts two values: message and percentage. We set those in an array and in the end convert it JSON for sending back to the client-side JavaScript.

Parameters

int $time: Timestamp.
