分页的第一个链接在 CodeIgniter 中显示 404 页面

Question

我正在处理类别页面的分页。我的路线是

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

进入分类页面的 url 是http://localhost/ecom/category/seats，但它显示 404 错误页面。但是当我给http://localhost/ecom/category/seats/1 它工作正常并且分页也工作正常第二个和第三个链接也可以工作但是当我在分页中单击 1 时它会出现 404 错误页面。我的控制器代码是

   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');
}

我可以尝试什么来解决这个问题？

Answer 1

它显示是因为您的router expect 2 parameter but you are giving 1 parameter seats

以这种方式定义您的路线

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

现在致电您的路线http://localhost/ecom/category/seats/0 获取类别页面 http://localhost/ecom/category/seats/1 第一次分页

如果你想分开你的分类路线Define two route one for category page and other for category pagination

分类页面

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

分类分页

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

Answer 2

所以，我为您的问题创建了一个演示，这对我有用↓↓

$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)

这是可能的，因为

路由将按照它们定义的顺序运行。更高的路线将 总是优先于较低的。(Reference)
