Hi first of all I should tell you that English is not my first language so excuse any misunderstandings. What I'm trying here is to access to the "donors" table data using the foreign key in the "packets" table and I need to get that data in the controller to use. I refer PacketID
in my view and in the staff
controller I need to get the specific DonorMobile
and DonorName
to send an SMS to that donor. I have tried creating multiple model functions but didn't work. Can it be done by that way or is there any other way? TIA!

Staff controller - I know you can't access data like $donorData->DonorID
in the controller
public function markAsUsed($packet)
{
$this->load->Model('Donor_Model');
$donorData = $this->Donor_Model->getDonors($packet);
$this->load->Model('Donor_Model');
$data = $this->Donor_Model->markAsUsed($donorData->DonorID);
$sid = 'twilio sid';
$token = 'twilio token';
$donorMobile = ' 94' . $donorData->DonorMobile;
$twilioNumber = 'twilio number';
$client = new Twilio\Rest\Client($sid, $token);
$message = $client->messages->create(
$donorMobile, array(
'from' => $twilioNumber,
'body' => 'Thank you ' . $donorData->DonorName . ' for your blood donation. Your donation has just saved a life.'
)
);
if ($message->sid) {
$this->load->Model('Donor_Model');
$this->Donor_Model->changeStatus($data->isAvailable);
redirect('staff/viewpackets');
}
}
Model
function getDonors($packet) {
$data = $this->db->get_where('packets', array('PacketID' => $packet));
return $data->row();
}
function markAsUsed($donor)
{
$data = $this->db->get_where('donors', array('DonorID' => $donor));
return $data->row();
}
function changeStatus($packet)
{
$data = array(
'isAvailable' => False,
);
return $this->db->update('packets', $data, ['PacketID' => $packet]);
}

Found the answer! You can do this only using the controller.
$packetData = $this->db->get_where('packets', array('PacketID' => $packet));
foreach ($packetData->result() as $row) {
$donorID = $row->DonorID;
$packetDonatedDate = $row->DonatedDate;
}
$donorData = $this->db->get_where('donors', array('DonorID' => $donorID));
foreach ($donorData->result() as $row) {
$donarName = $row->DonorName;
$donorMobile = $row->DonorMobile;
}

What you did in the answer is not advisable, using loops to fetch from tables will slow the system by large when you have large datasets. What was expected is to use JOIN queries to join the donors and packets tables as shown below:
$this->db->select('donors_table.DonorName,donors_table.DonorMobile,packets_table.*')->from('packets_table'0;
$this->db->join('donors_table','donors_table.DonorID=packets_table.DonorID');
$query = $this->db->get();
$result = $this->db->result();
Then you can iterate through each donor as below:
foreach($result as $row){
$donarName = $row->DonorName;
$donorMobile = $row->DonorMobile;
}
NB: It is always advisable to perform any fetch, insert, delete or update operations from the model, that is why Codeigniter is an MVC. Stop fetching data directly from database within Controllers.
