matching two columns in mysql table in codeigniter not working - php

Question

i am trying to display data using 2 tables in codeigniter, i have a products table with some products and another table with the id of the products, i did the following in controller:
public function index(){
$selectfeatured = $this->product->selectfeatured();
foreach($selectfeatured as $val){
$id=$val->pid;
$data['featured'] = $this->product->featured($id);
}
$this->load->view('home', $data);
}
in my model,
function selectfeatured()
{
$this->db->select('*');
$this->db->from('featured');
$this->db->order_by("id", "desc");
$this->db->limit(4);
$query = $this->db->get();
$result = $query->result();
return $result;
}
function featured($pid)
{
$this->db->select('*');
$this->db->where("id", $pid);
$this->db->from('product');
$query = $this->db->get();
$result = $query->result();
return $result;
}
this code only displays one product even though i have multiple products in both the tables, can anyone please tell me what is wrong in here

Answer 1

Make your $data['feature'] as an array:
public function index()
{
$selectfeatured = $this->product->selectfeatured();
$data['featured'] = array();
foreach ($selectfeatured as $val) {
$id = $val->pid;
$data['featured'][] = $this->product->featured($id); // add new item
}
$this->load->view('home', $data);
}
And make sure you display the featured array right way in your view, something like this:
<?php foreach ($featured as $feature) : ?>
<?php foreach ($feature as $product) : ?>
<div class="item"><img style="height:250px" src="<?php echo base_url(); ?>admin/uploads/products/<?php echo $product->pimage; ?>" alt="" class="img-responsive"></div>
</div>
<?php endforeach; ?>
<?php endforeach; ?>

Answer 2

The variable $data['featured'] is inside a loop and is getting new value on each iteration, and is overwritten on each iteration, that's why you are getting only one product, you need to use array_push or '+=' etc to append the other products.
