Gingechilla Posted April 12, 2006 Share Posted April 12, 2006 I have the following tables in my database:items < Holds all over the items information ect.userinfo < Holds information on userusersitems < Holds what the user has got.From the search page a user can add things from the items table into the usersitems table, that works fine.The problem I have is, how can I show what items a user does not have?

kenrbnsn Posted April 12, 2006 Share Posted April 12, 2006 The following is very high level coding. :-)Get all of the items and put into an array.Get all of the items the user has and put into an array.Do an array_diff() to find out what the user doesn't have.Ken Link to comment https://forums.phpfreaks.com/topic/7207-how-can-i-figure-out-how-to-show-this/#findComment-26216 Share on other sites More sharing options...
