How can I redirect to previous page after login

Title about sums it up.

Something like this

If (customer came from a different page on my site) {
redirect back to that page;
} else {
redirect as usual;
}

Any ideas on this?

The first thing you do is set up the url in a session variable on the page you are trying to go to. For example if you are trying to go to your account section then in the account.php control file just add: Now in the login.php control just add the redirect after a successful login. Fill it in with the session variable: or if you have ampersands involved

Since I won't know what page the user will come from, I should put
at the top of each tpl file, with account/account being changed?

I would suggest going with a "header login" extension. So, the customer can be on any page and log in directly from the header, staying on the same page after login (or being redirected to another page if you wish).

I use this one:
http://www.opencart.com/index.php?route ... on_id=2609

And I use the "stay on same page or redirect to whatever" redirects from this one:
http://www.opencart.com/index.php?route ... on_id=6979

The second one has several redirects set up for different pages (homepage, login page, logout page, everything else).

Just use the controler that was given to you to use. You might as well learn how open cart does it by default (because it happens everywhere)

An extension for this on the Opencart.
https://www.opencart.com/index.php?rout ... n_id=13998

It has 3 features: Page after login. Page after logout. Plus Strict Login.
