Laravel - Queues - Adding Jobs To Batches

Sometimes it may be useful to add additional jobs to a batch from within a batched job. This pattern can be useful when you need to batch thousands of jobs which may take too long to dispatch during a web request. So, instead, you may wish to dispatch an initial batch of "loader" jobs that hydrate the batch with even more jobs:

    $batch = Bus::batch([
        new LoadImportBatch,
        new LoadImportBatch,
        new LoadImportBatch,
    ])->then(function (Batch $batch) {
        // All jobs completed successfully...
    })->name('Import Contacts')->dispatch();

In this example, we will use the LoadImportBatch job to hydrate the batch with additional jobs. To accomplish this, we may use the add method on the batch instance that may be accessed via the job's batch method:

    use App\Jobs\ImportContacts;
    use Illuminate\Support\Collection;
     * Execute the job.
     * @return void
    public function handle()
        if ($this->batch()->cancelled()) {
        $this->batch()->add(Collection::times(1000, function () {
            return new ImportContacts;
You may only add jobs to a batch from within a job that belongs to the same batch.
