I'm trying to set up a cron queue, but for some reason, I don't manage to get this done.

Here is what I have so far:

function mymodule_cron() {
    // Setup the queue
    $queue = DrupalQueue::get('import_jobs');
    // Create cache
    drupal_flush_all_caches();
}

function mymodule_cron_queue_info() {
    $queues['import_jobs'] = array(
    'worker callback' => '_import_all_jobs',
    'time' => 15, 
    );
    return $queues;
}

The _import_all_jobs function does it's work excellent, so nothing wrong with that. I use the Ultimate Cron module and my cron job is listed over there:

But for some reason, nothing happens... So I'm wondering what I do wrong...

  • Have you actually got Cron running on the server?

You need to add items to your queue. You have created a queue, but haven't added anything to it, so nothing is being done.

$queue->createItem($item);

$item will get passed to the queue callback function (_import_all_jobs).

I would suggest modifying _import_all_jobs to import an individual job (_import_job). Then $item would be a job added to the queue and you let DrupalQueue do its thing.

  • That's what I figured, but what would the $item be? I don't need an array or something similar. All I need is the function _import_all_jobs to run on a cron job.

  • In that case, it can be anything you want, like NULL.

If you are not processing multiple items, you could just run _import_all_jobs from the cron:

function mymodule_cron() {
    _import_all_jobs();

    // Create cache
    drupal_flush_all_caches();
}

But it seems like _import_all_jobs is doing multiple things and should be modified to work as a DrupalQueue, as I've suggested in my first answer.
