Codeigniter model foreach pass array to controller -> to view - php

Question

Here is my model - I want to assign the rows and echo out on the view page e.g <?php echo $product?>
class Model_products extends CI_Model {
function printer()
{
$id = $this->uri->segment(3, 0);
$q = $this->db->get_where('printer', array('id' => $id));
if ($q->num_rows == 1)
{
foreach ($q->result() as $row)
{
echo $row->name; # THIS WORKS
$data['product'] = $row->name; # THIS DOES NOT WORK
$data['desc'] = $row->description;
$data['size'] = $row->size;
$data['options'] = $row->options;
$data['more'] = $row->more_info;
}
}
}
}
Here's my controller
public function products()
{
$this->load->model('Model_products');
$this->Model_products->printer();
$this->load->view('products', $data);
$this->load->view('pricing');
}
My view is
<h1>
<?php echo $product; ?>
</h1>
<p>
<?php echo $desc; ?>
</p>
<h3>
Size
</h3>
<p>
<?php echo $size; ?>
</p>
How do I properly pass my model array to my controller so that I can echo out on my view?

Answer 1

Simply return $data to controller
class Model_products extends CI_Model {
function printer()
{
$data = array();
$id = $this->uri->segment(3, 0);
$q = $this->db->get_where('printer', array('id' => $id));
if ($q->num_rows == 1)
{
foreach ($q->result() as $row)
{
// echo $row->name; # THIS WORKS
$data['product'] = $row->name; # THIS DOES NOT WORK
$data['desc'] = $row->description;
$data['size'] = $row->size;
$data['options'] = $row->options;
$data['more'] = $row->more_info;
}
}
return $data;
}
}
No win Controller
public function products()
{
$this->load->model('Model_products');
$data['products'] = $this->Model_products->printer();
$this->load->view('products', $data);
$this->load->view('pricing');
}
And in view
<?
echo '<pre>';
print_r($products);
?>
EDIT Also correct your model code.
foreach ($q->result() as $row)
{
echo $row->name; # THIS WORKS
$data[]['product'] = $row->name; # THIS DOES NOT WORK
$data[]['desc'] = $row->description;
$data[]['size'] = $row->size;
$data[]['options'] = $row->options;
$data[]['more'] = $row->more_info;
}
If you are not using multidimensional array it will overwrite the last record.

Answer 2

You need to return the data from the model back to the controller and then from there, pass the data to the view.
In your model function, place a return statement at the end.
return $data;
Then in your controller, assign the returned value from the model to a variable.
$data = $this->Model_products->printer();
Those 2 steps should fix your problem.

Answer 3

Where your return statement
if ($q->num_rows == 1)
{
foreach ($q->result() as $row)
{
echo $row->name; # THIS WORKS
$data['product'] = $row->name; # THIS DOES NOT WORK
$data['desc'] = $row->description;
$data['size'] = $row->size;
$data['options'] = $row->options;
$data['more'] = $row->more_info;
}
return $data;
}
and/or in your controller
public function products()
{
$this->load->model('Model_products');
$data = $this->Model_products->printer();
$this->load->view('products', $data);
$this->load->view('pricing');
}

I used #raheel's code and it works. But I would just change a bit:
$i=0;
foreach ($q->result() as $row)
{
echo $row->name; # THIS WORKS
$data[$i]['product'] = $row->name; # THIS DOES NOT WORK
$data[$i]['desc'] = $row->description;
$data[$i]['size'] = $row->size;
$data[$i]['options'] = $row->options;
$data[$i]['more'] = $row->more_info;
}
This will help extracting the data
