Showing results for tags 'registering globals'.
Hi, I am a complete novice to PHP and have started to use this book but have been very frustrated by it so far. I am only at the second chapter, attempting to build and validate a simple form yet I cannot successfully see the results owing to constant 'undefined variables' etc. According to the advice in the book these problems are caused by register globals being turned off and/or error reporting set too high, but I cannot do anything about either of these, so my question is... is this book realy of any use to me, and should it not have been written an a way which does not bring about these problems? Is there any other way around this and is it worth persevering with the book in the hope that these problems will not continue or should I just give up?
