add a "currency" from my site? Please explain.

[techiefreak05]

a currency.... "money" on my site... lets say, they upload a picture, for doing so they will get X amount of points.. and they can use tose points to "purchase" extra features.. or t-shirts/hats and other items.

Below the script where they successfully uploaded a picture, add the query which add points into your database.

Example:
[code]<?php
mysql_query("UPDATE members SET points='10' WHERE id='1'") or die(mysql_error());
?>[/code]

Ofcourse it will not be working, its just an example.
Btw... You need to do a sql query before that, and take the current point then add X's vaule into it.
