從2個模型的控制器功能查看數據

Question

我試圖通過控制器和模型從數據庫獲取橫幅圖像。

我的控制器：

class Home extends CI_Controller{ 
//put your code here 
public function __construct() { 
    parent::__construct(); 
    $this->load->model('home_model'); 
} 
public function index(){ 
    $data=array(); 

$data['bannerInfo']=$this->home_model->selectBanner($banner_id); 

    $data['result']=$this->home_model->selectCategory($category_id); 


    $data['banner']=$this->load->view('banner',$data, TRUE); 
    $data['maincontent']=$this->load->view('home_message',$data,TRUE); 
    $data['title']='NZ Furniture Products '; 
    $data['keywords'] = 'furniture bangladesh'; 
    $this->load->view('home', $data); 
    } 

我的模型：

class Home_Model extends CI_Model{ 
//put your code here 


public function selectCategory($category_id) 
{ 
    $this->db->select('*'); 
    $this->db->from('tbl_category'); 
    $this->db->order_by("category_id", "desc"); 
    $querey_result= $this->db->get(); 
    $results=$querey_result->result(); 
    return $results; 

} 

public function selectBanner($banner_id) 
{ 
    $this->db->select('*'); 
    $this->db->from('tbl_banner'); 
    $this->db->where('banner_id',$banner_id); 
    //$this->db->order_by("product_id", "desc"); 
    $querey_result= $this->db->get(); 
    $results=$querey_result->result(); 
    return $results; 
} 

查看 home_message :::

<?php foreach ($result as $values) { ?> 
<div class="single_product"> 
<div class="product_image"> 
     <a href="<?php echo base_url(); ?>home/category/<?php echo $values->category_id ?>"><img src="<?php echo base_url();?><?php echo $values->category_image ?>" /></a> 
    </div> 
    <span class="category_title"> <a href="<?php echo base_url(); ?>home/category/<?php echo $values->category_id ?>"> <?php echo $values->category_name ?></a> </span> 
</div> 

<?php } ?> 

旗幟

<div> 
<?php foreach ($bannerInfo as $values) { ?> 
<?php echo $values->banner_image ?> 
<?php } ?> 
</div> 

Answer 1

如果你想顯示所有的橫幅。你必須刪除where子句。默認排序是desc。

Controller文件：

class Home extends CI_Controller 
{ 
    public function __construct() { 
    parent :: __construct(); 
    $this->load->model('home_model'); 
    } 

    public function index() { 
    $data = array(); 
    $data['bannerInfo'] = $this->home_model->selectBanner(); 
    $data['result'] = $this->home_model->selectCategory($category_id); 
    $data['banner'] = $this->load->view('banner', $data, TRUE); 
    $data['maincontent'] = $this->load->view('home_message', $data, TRUE); 
    $data['title'] = 'NZ Furniture Products '; 
    $data['keywords'] = 'furniture bangladesh'; 
    $this->load->view('home', $data); 
    } 
} 

型號文件：

class Home_Model extends CI_Model 
{ 
    public function selectCategory($category_id) 
    { 
    $this->db->select('*'); 
    $this->db->from('tbl_category'); 
    $this->db->order_by("category_id", "desc"); 
    $querey_result= $this->db->get(); 
    $results=$querey_result->result(); 
    return $results; 

    } 

    public function selectBanner($order_by = "desc") 
    { 
    $this->db->select('*'); 
    $this->db->from('tbl_banner'); 
    $this->db->order_by("banner_id", $order_by); 
    return $this->db->get()->result(); 
    } 
}
