Can I link current php website with store login?

Hi, I currently have a simple login php site for buyers to login n order their clothes. Anyway to combine the login from the previous login page to zencart's login? Such that when buyers login from my old page, and they click on any of my zencart pages, they are still logged in and no need to re-login (vice versa). Thanks so much!

It can be done, but not easily.

anyone can help? been stuck with this issue for months! Thanks!

You have not had any other replies as most don't do this and don't want to do this.
There may be other ways to achieve what you want.

Post a link to your site so we can see what you are talking about.

When you say your existing login system is "simple", what encoding is it using to mask the login password? Is it using MD5 ?

Zencart uses MD5 hash algorithm to generate encrypted passwords, and even if your current login uses MD5 it may still be very difficult to "bridge" the two login systems.
