Can't view my variables?!?!?
Hi guys,
I have this problem where I make a text box on one page, and send it through the url, then try to view it on a php page but the variable doesn't come up. Anyone know what might be the problem? Thanks LeX

Off the top of my head I'd say this sounds like a register globals problem but without seeing some source code its hard to say. If you could post the problem code I'm sure someone can spot the error for you.

Here's the code for the html file:
Code:
<html> <head></head> <body> <form method=get action="text.php"> Who is your favourite author? <input name="Author" type="text"> <br> <br> <input type=submit> </form> </body> </html> And heres the php page code: Code:
<html> <head></head> <body> Your favorite author is: <?php echo $Author; ?> </body> </html> Anyone know the problem now? LeX

Yeah, that will only work if you have register globals turned on. Basically what happens with register globals is anything in $_GET, $_POST etc is put into a variable with the same name. So for example you have, $_GET ['Author'] from your query string so with register globals you get a variable $Author. If you have it turned off then you need to use $_GET ['Author'] instead.
That said register globals should be turned off and you should be using $_GET, $_POST etc for security reasons. For more details have a look around these forumns or a google search and you'll find loads of threads and articles about why this is the case. -KM-
