分頁的第一個鏈接顯示 CodeIgniter 中的 404 頁

Question

我正在處理類別頁面的分頁。 我的路線是

$route['category/(:any)/(:num)'] = 'public_controller/category/$1';

而 url 到 go 到類別頁面是http://localhost/ecom/category/seats但它顯示 404 錯誤頁面。 但是當我給http://localhost/ecom/category/seats/1時，它工作正常，分頁也工作正常，第二個和第三個鏈接也工作，但是當我在分頁中單擊 1 時，它會出現 404 錯誤頁面。 我的 controller 代碼是

   public function category($cat_slug = null,$offset = null){
 $cat_id = $this->db->where('cat_slug',$cat_slug)->get('categories')->row_array();
 $config['base_url'] = base_url() .'category/'.$cat_slug;
    $config['total_rows'] = $this->db->where('cat_id',$cat_id['cat_id'])->count_all('products');
    $config['per_page'] = 4;
    $config['uri_segment'] = 3;
$config['use_page_numbers'] = TRUE;
    $config['full_tag_open'] = "<ul class='pagination'>";
    $config['full_tag_close'] ="</ul>";
    $config['num_tag_open'] = '<li>';
    $config['num_tag_close'] = '</li>';
    $config['cur_tag_open'] = "<li class='disabled'><li class='active'><a href='#'>";
    $config['cur_tag_close'] = "<span class='sr-only'></span></a></li>";
    $config['next_tag_open'] = "<li>";
    $config['next_tagl_close'] = "</li>";
    $config['prev_tag_open'] = "<li>";
    $config['prev_tagl_close'] = "</li>";
    $config['first_tag_open'] = "<li>";
    $config['first_tagl_close'] = "</li>";
    $config['last_tag_open'] = "<li>";
    $config['last_tagl_close'] = "</li>";

    $this->pagination->initialize($config);
 $data['products'] = $this->public_model->category_page($cat_slug,$config['per_page'],$offset);
 $id['cat_slug'] = $cat_slug;
 $this->load->view('public_temp/header1');
 $this->load->view('public_temp/left1',$id);
 $this->load->view('public/category',$data);
 $this->load->view('public_temp/footer1');
}

我可以嘗試什么來解決這個問題？

Answer 1

它顯示是因為您的router expect 2 parameter but you are giving 1 parameter seats

以這種方式定義您的路線

$route['category/(:any)/(:num)'] = 'public_controller/category/$1/$2';

現在調用您的路線http://localhost/ecom/category/seats/0用於類別頁面http://localhost/ecom/category/seats/1用於第一個分頁

如果你想分開你的類別路線Define two route one for category page and other for category pagination

對於類別頁面

$route['category/(:any)'] = 'public_controller/category/$1';

對於類別分頁

$route['category/(:any)/(:num)'] = 'public_controller/category/$1/$2';

Answer 2

所以，我為你的問題創建了一個演示，這對我有用↓↓

$route['category']               = 'my_controller/category';       // this route handles all the requests without any additional segments
$route['category/(:any)']        = 'my_controller/category/$1';    // this route handles the requests when only one segment is present
$route['category/(:any)/(:num)'] = 'my_controller/category/$1/$2'; // this route handles the requests when there are two segments(2nd parameter being a number)

這是可能的，因為

路由將按照它們定義的順序運行。 較高的路線總是優先於較低的路線。（參考）

我還發現了一個類似的問題，您可能想看看。

希望這能解決您的問題。
