如何在 codeigniter php 控制器函数中传递参数
嗨，朋友们，我有这个函数来显示所有文章，我正在为不同的类别一次又一次地编写这个函数，因为 codeigniter 参数与 url 相关，我如何传递参数以便我可以重用这个函数？
这是我的控制器功能，用于显示所有新闻。
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');
}
hi friends i have this function to show all articles, i am writing this function again and again for different categories, because codeigniter arguments are related to url how do i pass arguments so that i can reuse this function ?
This is my controller function to show all news.
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');
}

考虑将大部分控制器逻辑移至模型方法中。然后，您将能够向此方法发送参数，该方法将根据您发送到该方法的参数将数据库结果返回到您的控制器。
Consider moving much of your controller logic into a model method. Then you'll be able send arguments to this method which will return back database results to your controller based on the arguments you send to the method.

分段编号如下：
1-news
2-本地
3-地铁
4-crime_is_up

http://example.com/index.php/news/local/metro/crime_is_up
The segment numbers would be this:
1-news
2-local
3-metro
4-crime_is_up
