How to pass the category id to model to get the appropriate subcatory of category_id

Answer 1

Hope this will help you :
Your view should be like this :
<ul class="list-inline">
<?php
if($category->num_rows() > 0)
{
foreach ($category->result() as $row)
{?>
<li>
<a href="<?=site_url('main/getsubcategory/'.$row->id);?>">
<img class="img-responsive center-block" width="80px" src="<?=site_url('assets/admin/uploads/category/'.$row->cat_home_image); ?>" alt="icon" title="icon" class="img-responsive" />
<p style="font-size:16px;"><?php echo $row->category_description; ?> </p>
</a>
</li>
<?php
}
}
?>
</ul>
Your controller's getsubcategory method should be like this :
public function getsubcategory($id)
{
if ($id)
{
$this->load->model("category_model");
$data["subcategory"] = $this->category_model->fetch_subcategory($id);
$this->load->view('category',$data);
}
}
Your model method fetch_subcategory should be like this :
Note : make sure all column name belongs to correct table alias
function fetch_subcategory($id)
{
$this->db->select('*');
$this->db->from('category c');
$this->db->join('category_language cl', 'cl.category_id = c.id');
/* Use $id here like this
$this->db->where('parent_id', $id);
*/
$this->db->where('c.parent_id', '1');
$this->db->where('cl.lang_id', '1');
$this->db->order_by('c.category_description', 'DESC');
$result = $this->db->get()->result();
return $result;
}
