I want to know how it works
if we click this link it will display 00000000 group.
according to me we need variable to pass the value in link.
if anybody knows answer please tell me
0000000 is a variable they are passing via the url. They then use $_GET to get the group name and display that groups page.
If you wanted to create a link to this (they are using mod_rewrite to make it look nice I’m sure) it would be…
<a href="https://www.facebook.com/groups/?id=0000000">Group 0000000</a>Don’t quote me on this because all I can do is assume that is what they are doing
If you want to learn more there are a lot of tutorials about this if you google it.
