Displaying multiple data with different date using PHP and Codeigniter - php

Question

I have a problem on getting multiple data of a single patient. I can only generate 1 physical examination result and I can't get all of it.
My Controller
public function print_sum_report($case_id){
//fetching all data from different tables
$case_id = 1;
$postnatal_id = 1;
$this->load->model('Prms_model');
$data['n_status'] = $this->Prms_model->get_status_f($case_id);
$data['n_mh'] = $this->Prms_model->get_mh_f($case_id);
$data['n_pe'] = $this->Prms_model->get_pe_f($case_id);
$data['n_post'] = $this->Prms_model->get_pn_f($postnatal_id);
$data['n_infant'] = $this->Prms_model->get_infant_f($case_id);
$this->load->view('report/reportsum', $data);
// print_r($data);
}
My Model
public function get_pe_f($case_id){
// joining 2 tables (physicalexamination and patient_info by ID)
$this->db->select('*');
$this->db->from('physicalexamination');
$this->db->where('case_id', $case_id);
$this->db->join('patient_info', 'patient_info.patient_ID = physicalexamination.Patient_ID');
$query = $this->db->get();
return $query->result();
}

Answer 1

$data['n_pe'] is a result object which contains many rows. You need to iterate over it to gather all the rows:
foreach($data['n_pe'] as $pe) {
var_dump($pe);
}
Also, you could write your model this way:
public function get_pe_f($case_id) {
// joining 2 tables (physicalexamination and patient_info by ID)
return $this->db
->where('case_id', $case_id)
->join('patient_info', 'patient_info.patient_ID = physicalexamination.Patient_ID');
->get('physicalexamination')
->result();
}
