Oscmax/Oscommerce - Check if customer is logged in

Sometimes you might want to specify some processing to occur or something to only show up if the customer is logged in. So before you write anything you need to specify this login condition, or check if a login session has started.

This is much simpler to do than it seems. All you need is this line:

if ((tep_session_is_registered('customer_id')) && (!tep_session_is_registered('noaccount'))) {
your code
}

which basically tells the browser to check if the session is registered but make sure that it's an account (rather than PWA session).

In oscommerce, you don't need the "noaccount" session since there is no PWA allowed. So it would be:

if (tep_session_is_registered('customer_id')) {
your code
}

Replace "your code" with whatever code you have, and at the end don't forget to put the closing bracket or you'll get a parse error.

For example, the following code redirects a logged in customer to the new products page, and otherwise sends a user to the login page:

if ((tep_session_is_registered('customer_id')) && (!tep_session_is_registered('noaccount'))) {
tep_redirect(tep_href_link(FILENAME_PRODUCTS_NEW));
}
else {
tep_redirect(tep_href_link(FILENAME_LOGIN));
}

And in oscommerce:

if (tep_session_is_registered('customer_id')) {
tep_redirect(tep_href_link(FILENAME_NEW_PRODUCTS));
}
else {
tep_redirect(tep_href_link(FILENAME_LOGIN));
}

Enjoy!
