Uh, bit lost at this point. Still new, and possibly in over my head.
I'm trying to make a nfo/txt to PNG image converter for a website. Have to save the png to disc, and discard any uploaded nfo/txt. I can get it to convert and save a PNG image of text that I put into a text box form fairly easily, but I can't manage to get the uploaded file to work.
Its not just the if statement, even though that is screwed up =.=, as I've totally removed it and this still doesn't work. 🤷
3 Files in total. Bottom one is a modified version of the second one.

Errors i get from this modified nfotest.php :
[03-Feb-2010 10:27:07] PHP Warning: file() [<a href='function.file'>function.file</a>]: Filename cannot be empty in /*/nfotest.php on line 9
[03-Feb-2010 10:27:07] PHP Warning: implode() [<a href='function.implode'>function.implode</a>]: Invalid arguments passed in /*/nfotest.php on line 10
Also, I've tried adding both a "/" and a "./" to the $location and again to the file() to try to make the location proper, as someone suggested on a different forum, with no luck. Hopefully someone has a solution. Thanks guys!
