如何在codeigniter php控制器函數中傳遞參數

Question

嗨，朋友我有這個函數來顯示所有文章，我一次又一次地爲不同的類別寫這個函數，因爲codeigniter參數與url有關，我如何傳遞參數使我可以重用這個功能嗎？

這是我的控制器功能來顯示所有消息。

function all_news(){ 

    //do some pagination 
    $this->load->library('pagination'); 
    $config['base_url'] = 'http://localhost/news/all_news'; 
    $config['total_rows'] = $this->db->get('articles')->num_rows(); 
    $config['per_page'] = 10; 
    $config['num_links'] = 7; 
    //some css for pagination 
    $config['full_tag_open'] = '<div id="pagination">'; 
    $config['full_tag_close'] = '</div>'; 
    //initialize pagination 
    $this->pagination->initialize($config); 
    //end pagination 

    $data['title'] =" All News"; 

    //for pagination 
    $data['query']= $this->db->order_by('id','desc'); 
    $data['query'] = $this->db->get('articles',$config['per_page'],$this->uri->segment(3)); 

    $this->load->vars($data); 
    $this->load->view('main/all_news'); 
} 

Answer 1

考慮將大部分控制器邏輯移動到模型方法中。然後，您將能夠向此方法發送參數，該參數將根據您發送給方法的參數將數據庫結果返回到控制器。

Answer 2

http://example.com/index.php/news/local/metro/crime_is_up

段數將是這樣：

1 - 新聞
2-局部
3地鐵
4 crime_is_up

$product_id = $this->uri->segment(3);//metro
