not able to retrieve data from database using codeigniter - php

Question

I am new to CodeIgniter. I have retrieved data from one table but I'm not able to retrieve the data from another table. The view part is not working. Due to some reason the PDF is displaying blank (using tcpdf). Can we fetch it as array? If yes, then how can we fetch it as array?Some of the data appears to be printed below the button that I press.It does not display on the pdf that is generated after the we click on the button.
code :
controller
index(){
$this->load->database();
//load the model
$this->load->model('Order_model');
//load the method of model
$data['h']=$this->Order_model->select();
//return the data in view
$this->load->view('includes/orderPdf', $data);
}
model
public function select()
{
//data is retrive from this query
$query = $this->db->get('master_user');
return $query;
}
view
<?php
foreach ($h->result() as $row)
{
?><tr>
<td><?php echo $row->mobile_no ?></td>
<td><?php echo $row->country ?></td>
</tr>
<?php }
?>

Answer 1

Best way to set up is probably similar to:
Controller:
$this->load->model('Order_model', 'Order');
$data['orders'] = $this->Order->getOrder();
Model:
public function getOrder() {
$q = $this->db->get('master_user');
return $q->num_rows() ? $q->result_array() : [];
}
View:
<?php foreach($orders as $order) { ?>
<tr>
<td><?=$order['mobile_no']?></td>
<td><?=$order['country']?></td>
</tr>
<?php } ?>
Now you can also add an if(empty($orders)) and put in "no orders to show" or similar.
