foreach loop not working with laravel queue - php

Question

I am using sync (local driver) for pushing up a queue in a update method of EmailCampaignController, which uses another method of the same controller named emailQueue
like this
Queue::push('EmailNewsletterController#emailQueue', array('campaign_id' => $campaign_id));
The emailQueue uses a foreach loop which runs correctly for once after that it gives error as if the $campaign_id is undefined
here is the emailQueue method
public function emailQueue($job, $data) {
// Queue Starts here
$emailCampaign = EmailCampaign::find($data['campaign_id']);
$emailCampaign->status = 'In Progress';
$emailCampaign->last_activity = Carbon::now();
$emailCampaign->save();
$data = $emailCampaign->emailCampaignNewsletter;
$contacts = $emailCampaign->contactList->contacts;
foreach ($contacts as $contact) {
$emailBody = [
'message' => [
'subject' => $data['email_title'],
'html' => $data['email_body'],
'from_email' => $data['from_email'],
'to' => [['email' => $contact['email_address']]]
]
];
$response = Mandrill::request('messages/send', $emailBody);
EmailCampaignRecord::create([
'email_campaign_id' => $data['campaign_id'],
'mandrill_email_id' => $response[0]->_id,
'status' => $response[0]->status,
'to_email' => $contact['email_address']
]);
$contact->last_activity = Carbon::now();
$contact->save();
}
$emailCampaign->status = 'Sent';
$emailCampaign->save();
$job->delete();
// Ends here
}
What am I doing wrong here? why is it not working like a normal loop ?

Answer 1

The problem was with email_campaign_id to be null because $data['campaign_id'] was null the correct foreign key was $data['email_campaign_id'] that's what stopped the process - I should have tested it before putting it in the queue
after changing the code
EmailCampaignRecord::create([
'email_campaign_id' => $data['campaign_id'],
'mandrill_email_id' => $response[0]->_id,
'status' => $response[0]->status,
'to_email' => $contact['email_address']
]);
to
EmailCampaignRecord::create([
'email_campaign_id' => $data['email_campaign_id'],
'mandrill_email_id' => $response[0]->_id,
'status' => $response[0]->status,
'to_email' => $contact['email_address']
]);
the problem was solved
