Hi there everyone, I am not sure if anyone has encountered this particular problem before (it seems like I may have uncovered a bug in FireFox). Basically when you login to aMember, aMember sets various PHP Session variables such as: Code: $_SESSION['_amember_user']['name_f']; // the member's first name $_SESSION['_amember_id']; // the member's aMember ID I am actually using these Session variables to allow members of my system to store and retrieve information about themselves (in a MYSQL database) within their member area. I have built my system using PHP pages that contain embedded iFrames. The pages displayed within the iFrames are simply other PHP pages that extract other bits of relevant data from the database. This all works 100% perfectly in Internet Explorer but FireFox is not playing the game... Basically, viewed individually every page works fine in FireFox, but when you place the same pages within iFrames FireFox only retrieves the Session variables for the main page AND NOT for any of the embedded iFrames. Sounds like a bug to me but if anyone has mastered this (or has any suggestions) I would be most grateful. I have posted this on the Mozillazine.com forums as well and will post a solution here (hopefully there will be one ) as it may save someone a lot of time in future. Cheers!
