HMVC和动态小部件 [英] HMVC and dynamic widgets

问题描述

我使用窗口小部件作为部分视图，它有自己的控制器（所以它自己的动作），它几乎放置在所有页面。我通过HMVC实现这个渲染，这只是伟大的。

I use the word widget as a partial view that have its own controller (so its own actions) and it is placed in almost all pages. I implement the rendering of this via HMVC, that is just great.

现在，问题是小部件本身执行动作。想想购物车小部件。该小部件放置在所有页面中，以便用户可以一直看到他/她的东西。和小部件有相关的动作，例如：RemoveItem，RefreshCart，ApplyDiscountCoupon等这样的动作应该触发一个按钮或链接，链接应该是类似的（在HMVC）：

Now, the problem is that the widget itself execute actions. Think about a shopping cart widget. That widget is placed in all pages so the user can see his/her stuff all along. And the widget have actions that are related to it, for instance: RemoveItem, RefreshCart, ApplyDiscountCoupon, etc. Such actions should trigger by a button or link and the link should be something like (in HMVC):

<a href='<?site_url()?>/cart/cart/removeitem/the_item_id'>Remove this item</a>

好的。现在用户点击该链接，购物车模块和购物车控制器加载并执行操作，操作应如下所示：

Ok. Now the user clicks that link, the cart module and cart controller are loaded and the action is executed, the action should look something like:

function removeitem($itemid)
{
     // remove the item from db
     ...

     // "load the view"  ???
}

正如你可以看到的，我的问题是如何加载视图在HMVC模块。事情是，如果我只加载购物车视图，它将只显示我的车，我不能只是重定向或加载主页面，因为它可以是任何主页面，即：购物车可以在任何主页面（选择产品，继续购买，查看产品详情，结算信息，结帐等）。 ：/

As you can see, my question is how to load the view in a HMVC module. The thing is that if I only load the cart view, it will only show my cart, and I can’t just redirect or load the main page because it can be any main page, that is: the cart could be in any main page (select product, keep buying, see product details, billing info, checkout, etc). :/

另一件事：要求是我不能在这个项目中使用AJAX。

Another thing: a requirement is that I can’t use AJAX in this project.

你知道HMVC如何处理这个问题吗？

Do you know how HMVC handle this?

提前感谢。

推荐答案

好的。没有运气与社区。然而，我发现了一个解决方法。希望对某人有帮助。

Ok. No luck with the community. Nevertheless I found a workaround. Hope would be helpful to someone.

HMVC没有自然的解决方案。所以我决定使用这个解决方法：

HMVC doesn't have a natural solution to this. So I decided to use this workaround:

1. 在每个主控制器（即没有窗口小部件，此会话中的当前网址（/ controllers / keep_buying.php）

1. Into each main controller (that is, no widget, no partial view) I grab the current url in session this way (/controllers/keep_buying.php):

class Keep_buying extends Controller
{
    function Keep_buying()
    {
        parent::Controller();
        $this->session->set_userdata('main_uri', uri_string()); 
    }
    ...
}

在我的部分视图窗口小部件（HMVC模块视图）我有一个正常的链接到我的窗口小部件控制器（/ modules / cart / views / cart_show.php）：

Then in my partial view widget (HMVC module view) I have a normal link to my widget controller (/modules/cart/views/cart_show.php):

<a class="button" href="cart/cart/additem">Add Item</a>  

在控制器动作（HMVC模块控制器操作），我检索当前主页，然后重定向到该页面，隐式将进入我的窗口小部件流（由于HMVC）。

At the controller action (HMVC module controller action) I retrieve the current main page, do stuff and then redirect to that page, that implicitly will get into my widget flow (due to HMVC).

class Cart extends Controller
{
    ...
    function additem()
    {
        $to_redirect = $this->session->userdata('main_uri');
        // add-item work stuff...
        redirect($to_redirect);
    }
}

那就是。这不是理想的方法IMHO，但工作。

That is. Is not the ideal approach IMHO, but works.
