Question

I’m using sessions to store products viewed, but I’m having a problem printing out all of the items when I query the database.

Controller

$hello_world = $this->session->all_userdata();


foreach($hello_world as $key=>$product_id) {
 $query['products']  = $this->Global_products->globalFindProducts($product_id);

  echo $product_id; // Right here it echos all the items in the session.

 }

Model

function globalFindProducts($product_id) 
{
$this->db->join('price','product.modelNumber = price.modelNumber','left')->where('product.modelNumber',$product_id);
$this->db->group_by('product.modelNumber');
$query = $this->db->get('by.product');
return $query->result();
}

View

<?php foreach($products as $product) { ?>
<div><?php echo $product->name; ?></div>
<?php } ?>

In my view I can only see one item, not all of them. Can someone please give me your advice as to how you would approach solving this problem?

Thanks in advance

Answer 1

Try this, I haven’t really coded in CodeIgniter, so its a best guess:

Controller

$hello_world = $this->session->all_userdata();

foreach($hello_world as $key=>$product_id) {
    $query['products'][]  = $this->Global_products->globalFindProducts($product_id);
    echo $product_id; // Right here it echos all the items in the session.
}

Note: Here I’m making the $query['products'] an array, so all results from
$this->Global_products->globalFindProducts($product_id); are stored
