TheJoey Posted October 1, 2009 Author Share Posted October 1, 2009 ahh sorry if i didnt explain myself well guys. i tend to do that sometimes. I have a shopping cart and when i add a item it displays item name : (Nothing here as 1) : price then when i click add again it adds it as item name : 1 : price where i want 1 to be a incremental Quote Link to comment Share on other sites More sharing options...

TheJoey Posted October 1, 2009 Author Share Posted October 1, 2009 When im adding to my shopping cart. It is being display as an empty value, inside quantity when its really a 1. So then the incremental is then out of wack the next time i add a item. so if instead of it being display as 2 it is being displayed as 1. Because of the fact that its starting off as NULL.

redarrow Posted October 1, 2009 Share Posted October 1, 2009 you can set the database to a default number, or you can use array_push() function. or is it array_unshift forgot now..... your see all the array functions available in php. http://uk3.php.net/manual/en/function.array-unshift.php Quote Link to comment Share on other sites More sharing options...

So post the relevant code that creates an item in your cart. We can't do anything but post examples without the relevant code. Quote Link to comment Share on other sites More sharing options...
