在Codeigniter中过滤，排序和分页 [英] Filter, sort and paginate in Codeigniter

问题描述

Ive最近开始使用CodeIgniter，因为我在寻找一个非常轻量级的框架，它似乎是一个顶级的选择。

Ive recently started using CodeIgniter as I was searching for a very lightweight framework and it seemed to come up as a top choice.

我是新的整个MVC事情，享受它，但被困住似乎很简单的东西。

I am new to the whole MVC thing, enjoying it but am stuck with something which seems very simple.

我编写一个CMS，需要一种方法来过滤，排序和分页的结果。我习惯了使用querystrings，所以我会有一些类似于：

I am coding a CMS and need a way to filter, sort and paginate the results. I am used to doing it with querystrings, so I would have something along the lines of:

articles.php?order=title&sort=desc&filter=articletitle&page=5

我不知道我会如何在CI中这样做，所以我只是打开EnableQueryStrings在配置和它的工作正常，但我得到的感觉它可能不是最优雅的解决方案。

I have no idea how I would go about doing this in CI so I just turned on the EnableQueryStrings in the config and it works fine, but i am getting the feeling its probably not the most elegant solution.

我可以有

index.php/articles/index/order/title/sort/desc/filter/articletitle/page/5

但对我来说这看起来很不灵活，如果我不需要排序，确保我正在查看正确的uri段。

but to me this seems very inflexible, what if for example i dont need to sort, how would i make sure i am looking at the correct uri segment?

任何想法？

推荐答案

您是否尝试过实现 _remap 函数？它会将所有查询重定向到控制器到该函数，允许你实现尽可能多的（或尽可能少的）。

Have you tried implementing the _remap function? It will redirect all queries to the controller to that function allowing you to implement as many (or as few) of those as you like.

你可以这样做：

class Articles extends Controller
{
    // Note: No need for a "order" or even an "index" function!
    public function _remap()
    {
        $assoc = $this->uri->uri_to_assoc( 4 );
        /* $assoc is now 
           array( "order"=>"title",
                  "sort"=>"desc",
                  "filter"=>"articletitle", 
                  "page"=>5); */
    }
}
