How to redirect to previous URL after login - zend-framework

Question

I want to make redirection after login action to previous URL. Please tell me how to do that?

Answer 1

Store the page before Login into Session, After login , read the previous page url from the session and redirect the use to that page.

Answer 2

You can pass the "return" URL as a parameter to the login page. i.e http://yourserver.com/login/?return=http%3a%2f%2fyourserver.com%2fsomedir%2fsomething%2f. After a successful login you then use the get parameter to redirect by using a simple HTTP header location:http://yourserver.com/somedir/something/.
This is, for example, practiced in different Google and Microsoft services where there is a single page for signing in and different services that require the user to be loogged in.

Answer 3

You may this use Action helper I wrote some time ago. Cheers!
