Question

I have a website layout divided into the multiple partial files. One of them is a view which seats in the sidebar. There is a link in it (Facebook Connect), when I press it, it call a specific function, when it’s completed without any errors, i received a blank page.

How to program it, so after processing a function inside another Controller, it will stay at the same url ?

Here is a visual. Imagine that I’am on this url http://localhost/web/blog. Here, on that page, i have a sidebar loaded with a link in it, which once it’s pressed it will process a function. The url of this link in the sidebar is http://localhost/web/member/facebook_login.
After it’s done, it should stay on the same url http://localhost/web/blog instead of /web/member/facebook_login.

Is it possible to do it without using a redirect() function ? So it will stay on the same page whenever you are, if your url is /web/home or web/about-us etc. ?

Thanks in advance guys

Answer 1

Why using the HTTP referrer is a bad idea, i just explained in my comment.

The url of this link in the sidebar is http://localhost/web/member/facebook_login

Then you should put the URL of the current page into that link, as a parameter:

http://localhost/web/member/facebook_login?go_back_url={url_of_the_current_page}

Then, after successful login, you can use the value of the parameter go_back_url to redirect back to the address it contains.
