xyph Posted July 28, 2011 Share Posted July 28, 2011 Do you want us to code for you, or do you actually plan on implementing an example into your existing code? This is a VERY VERY simple logic problem, and if you're able to code a whole purchasing system, this shouldn't be a problem. Don't give me BS like "I'm trying to learn." A complex script is a terrible spot to start, especially if you cant grasp if/then/comparison operators. When you loop out your items to display them, add a simple check if( $users_points < $item_cost ) { echo '<button type="button" disabled="disabled">Not Enough Money</button>'; } else { echo '<input type="submit" name="buy" value="Buy me">'; } Link to comment https://forums.phpfreaks.com/topic/243125-help-with-online-based-manager-phpmysql/#findComment-1248750 Share on other sites More sharing options...
