So i have been at this for a day I know its simple but my brain is no longer functioning correctly. I have a script that uploads a picture, writes some contents to a file. I need to access the variable "ext" below so i can write it and save it into the new file that is being created. Problem is that the only way i have been able to write a variable to the file is if it is defined within the actual funtion being sent to the file in the variable "somecontent". I have messed with globals, sessions and sending it through the url. I think im on the wrong track, anyway heres the code.
