How to change data variable value in codeigniter? - php

Question

I'm trying to create a search form in codeigniter. This is my controller and model,
Shop.php [ Controller ]
public function s(){
$q = $this->input->get('q');
if( $q == null ){
$this->index();
}
$data['products'] = $this->product_model->search_products( $q );
$this->load->view('shop', $data);
}
Product_model.php
public function search_products( $keyword ){
$this->db->select('product.id, product.product_name, product.product_description, product.product_image1,
brand.brand_name, category.category_name, type.type_name, stock.selling_price,
(SELECT COALESCE(ROUND(SUM(rate)/( COUNT(rate)*5 )*100), 0) FROM rating WHERE rating.product_id = product.id)AS rating,
(SELECT COALESCE(COUNT(rating.id), 0) FROM rating WHERE rating.product_id = product.id)AS rate_count');
$this->db->from('product');
$this->db->join('stock','stock.product_id = product.id');
$this->db->join('brand', 'brand.id = product.brand_id');
$this->db->join('category', 'category.id = product.category_id');
$this->db->join('type', 'type.id = product.type_id');
$this->db->join('color', 'color.id = product.color_id');
$this->db->where('MATCH(product.product_name) AGAINST("'.$keyword.'")');
$this->db->or_where('MATCH(brand.brand_name) AGAINST("'.$keyword.'")');
$this->db->or_where('MATCH(category.category_name) AGAINST("'.$keyword.'")');
$this->db->or_where('MATCH(type.type_name) AGAINST("'.$keyword.'")');
$this->db->where('stock.qty >', 0);
$this->db->group_by('product.id');
$query = $this->db->get();
return $query->result_array();
}
But return value in null. So I tried calling search_product( $keyword ) function in my view and it worked. but when I print $data['product'] variable and its empty.
What is the problem here? Thank you.
Edit
The search result shows here.
<div class="row product-list-item">
<?php
// This is just used for check the query
$p = $this->product_model->search_products( 'mesh' );
echo '<br>';
print_r($products);
if( $products != null ){
foreach ( $products as $product ){
?>
