I have made this code for giving out +1 point, but it doesn't work properly.
mysql_query(" UPDATE member_profile SET points= ' ".$points." ' + 1 WHERE user_id = '".$userid."' ");
the $points variable is the user´s points right now.. I want it to plus one to it.. so example if he had like 5 points, it should be 5+1 = 6.. but it doesnt, it just changes to 1
What have i done wrong? thank you
