Re: Creating Dynamic Variables

That's because you are registering 'name', which is to say $name, rather that whatever is *inside* of $name... Okay, the docs *DO* point out that you need to use the name of the variable for session_register, not the varible itself, but $name *HOLDS* the name of your variable. In other words, consider this: <?php $name = 'foo'; $foo = 42; session_register('foo'); #RIGHT session_register($foo); #WRONG session_register($name); #RIGHT, same as session_register('foo') since $name == 'foo' session_register('name'); #WRONG, that's registering $name, not $foo ?> Hope that makes sense. Oh, and use error_reporting(E_ALL) to crank up your warning messages. You'll end up writing better code because of it. -- Like Music? http://l-i-e.com/artists.htm
