如何在CakePHP中重定向后保留页码？ [英] How do you maintain page number after redirect in CakePHP?

问题描述

我有一个索引视图列出项目，它是一个长列表，所以我使用Paginator限制项目到50到一个视图。

I have an index view that lists items, and it's a long list so I use Paginator to limit items to 50-to-a-view.

每个项目有一个编辑链接，转到具有输入/验证等的编辑视图。当提交表单时，我将使用重定向到索引视图。

Each item has an "edit" link that goes to an edit view with inputs/validations/etc. When that form is submitted, I redirect the use back to the index view.

到目前为止很好，但这里是rub：

So far so good, but here's the rub:

如果用户在索引的第N页，并且他们单击编辑和编辑项目，我希望它们被重定向回索引的第N页。如果我知道页码，我可以坚持/ page：N到结束的URL，但我不知道如何我可以得到页码。 （N可以是任何页码，但特别是> = 2）

If a user is on page N of the index and they click edit and edit an item, I want them to be redirected back to page N of the index. If I knew the page number, I could just stick "/page:N" on to end of the URL, but I have no idea how I can get the page number. (N could be any page number, but especially >=2)

任何想法都会感激。

推荐答案

页码应该是列表视图中$ params var的一部分。只需将其粘到编辑链接的末尾，并从那里处理它。在编辑页面上，您将需要一种方法来接收可选的页码，在提交任何表单时存储它，并返回到具有相同页码的列表。

The page number should be part of the $params var in the list view. Just tack it onto the end of the edit link and handle it from there. On the edit page you will need a way to take in the optional page number, store it during any form submission, and forward back to the list with the same page number.
