Objective: I want users to buy items and i can set a ammount of number items in stock. Now Say i make a system where users can click on a item and it subtracts the number of items from the usershop.(heres the question) Instead of adding to the ammount giving how can i subtract from it?
Well could i do this(assume i connected to database etc..):
$blah = mysql_fetch_array($my_array_idefined); $bam = $blah['points']-1; mysql_query("UPDATE upoints SET points='$bam' where id='1' ");
would that work? anybody got an idea of where im going with this? Thanks in advanced
