View Full Version : Google Style Login

When you view source on the google login page, you see this as the form.
<form id="gaia_loginform" action="https://www.google.com/accounts/LoginAuth?continue=http%3A%2F%2Fwww.google.com%2Fwebhp%3Fsourceid%3Dnavclient%26ie%3DUTF-8&hl=en" method="post" onsubmit="return(gaia_onLoginSubmit());">
I was wondering on how you do this instead of the usual

Google is still using PHP or some other language to process the login - they just added some parameters that their script uses.
This portion actually points to a script like login.php...you just can't tell because the URL is rewritten
This sets $_GET['continue'] (assuming they use PHP) to http://www.google.com/webhp. That's likely where you go after you login.
Equivilant to ?sourceid=navclient. This is setting the $_GET['sourceid'] value for the webhp page.
&ie=UTF-8 (content encoding)
See http://www.blooberry.com/indexdot/html/topics/urlencoding.htm for more info on URL encoding (all those % codes).
Google really isn't doing anything special...they just send some helper values to their login script so it knows how to do a couple things.

Looks like perl.

Yea basically they're adding parameters to process on the login page. So for example let's say you have in your url
On the login page you could use $_GET['continue'] to grab that parameter, and when the login is done you could redirect them to http://www.site.com or any other url in that parameter.
