I am currently in Afghanistan and don't have much access to look these questions up. I consider them basic and regret having to post them here. When passing variables using GET as in: index.php?first=value?second=value My script is reading the first value, however through an included file and another function, it can't read the second. What scope do these variables have? Or what other reasons for not being able to read the variables might there be?
Your GET syntax is wrong, you should be using:
index.php?first=value&second=value The way you were doing it you should see the second variable contained within the first value.
Second: When dynamcially creating an image: I am drawing an image based on data retreived from a mySQL resource. However, my DB code is in the same file as the php image file and I get the non-descriptive error of "Error in the image 'url'" Are you allowed to do any other functions inside an image header other than image functions? (Functions being; open a connection to mySQL and do queries) Thank you for your help, -Kristopher Kane
You can use any valid PHP code before or after sending an image header so long as you don't inadvertantly output to the browser. I am not sure what that error message means though, I'm sure someone who uses the image functions more frequently could give you some clues.
