How do I assign unique id to call data?

[Olufemi Adeyemo]

Hi friends,

I need your help concerning this issue. How do I call data of a user from database to appear on a page with an assigned unique id referral link like this:

http://mysite.com/index.php?Id=12345(primary id number in the database)

for each registered user of my site with a common web-page for all? What code do I use?

Although I used the code below it worked fine only when I put the particular member‘s id in the select code:

mysql_query(“SELECT * FROM $tablename WHERE id=12345“) or die (mysql_error());

but I want to use a common page for all members while each of them will have a unique referral id link like the one above assigned to them.

Your assistance will be greatly appreciated. Thank you in advance.
