category wise article not showing in codeigniter - php

Question

I have created a home page in codeigniter and have created a home controller in it. Index method has been created in the home controller, in which all articles have been shown.
Now another function is added in the home controller in which to show all articles of single category, I also made model but in this show all articles in all categories.
If I am calling only method then query is working but showing in home html page then all data showing all category.please help me
<?php
class Home extends CI_Controller{
function index(){
$this->load->model('Article_model');
$param['offset']=4;
$param['limit']=0;
$articles=$this->Article_model->getArticlesFront($param);
$data['articles']=$articles;
$this->load->view('front/home',$data);
}
function computerCategory(){
$this->load->model('Article_model');
$param['offset']=4;
$param['limit']=0;
$articles=$this->Article_model->getComputerArticlesFront($param);
$data['articles']=$articles;
$this->load->view('front/computer_category',$data);
}
}
?>
/*front computer category methods*/
function getComputerArticlesFront($param= array()){
$query = $this->db->get('articles');
if(isset($param['offset']) && isset($param['limit'])){
$this->db->limit($param['offset'],$param['limit']);
}
if(isset($param['q'])){
$this->db->or_like('title',trim($param['q']));
$this->db->or_like('author',trim($param['q']));
}
if(isset($param['category_id'])){
$this->db->where('category',$param['category_id']);
}
$this->db->select('articles.*,categories.name as category_name');
$this->db->where('articles.category',43);
$this->db->order_by('articles.created_at','DESC');
$this->db->join('categories','categories.id=articles.category','left');
$query = $this->db->get('articles');
//echo $this->db->last_query();
$articles = $query->result_array();
//echo $this->db->last_query();
return $articles;
}
