If I'm correct, 'REQUEST' will catch both 'POST' and 'GET' args.
Personally, I've written a function to emulate register globals=on without
actually compromising the system. It parses the arg and matches it against
the various types. It helps me to maintain my lazy programming approach -
not having to think about where the arg is coming from.

hi!
i get:
Fatal error: Call to undefined function: imagecreatefromjpeg() in

i have wamp5 with php 4.3.9...
i can get the script to work by uncomment the use of gd2 in php.ini but the
script doesnät work as it should anyway. I was able to resize images before,
but now it doesn't work...
has there been som changes since 4.3.4?

Hello, I had the same problem some days ago.
Check if you have the php_gd2.ini in your PHP extensions dir.
You need to check this directory in your php.ini file to be sure it's
correct.

i have an image upload script that uses fixed image names... when i update
an image, that image will be replaced at the server using the same name as
the old image... now, my browser doesn't check for the new image but checkes
it cache instead and ofcourse finds the old image... how can i fix this?
i've allready added headers for not letting the page cache;
(<META HTTP-EQUIV="CACHE-CONTROL" CONTENT="NO-CACHE">
<META HTTP-EQUIV="PRAGMA" CONTENT="NO-CACHE">)

Here's a little trick that works for me
$cur_time = time();
print "<img src='" . $file . "?" . $cur_time . "'>";
Since each time you load the page the image name will be different (since
$cur_time will always change) the browser thinks the files are always
different since the name changes - and thus you force a reload of the image.
I do this on scripts that I make changes to images in PHP and need to see
the new image after the page reloads instead of seeing the pre-processed
image.
(I also do something similar with JavaScript for webcam images to prevent
caching)

Hi everyone,
"Assuming you have not omitted any of the code for script 2:

> $username = $_REQUEST['userName'];
vs.
> ". $_POST["userName"] ."</h3>";

And assuming both Armando and Mikes answers work which method is
the more correct?"
Interestingly enough, in this particular situation, it was neither Mike's
answer nor Armando's that did the trick for me, although I certainly tried them
both, and have kept both answers in my PHP Tutorials folder for future
reference, and I appreciate the help of both very much. But instead, it seems
that Trevor has the correct answer to my particular problem. He suggested that
my web server might not be configured correctly, and at least with my very
limited beginner's knowledge of PHP, since neither Armando's suggestion or
Mike's worked, I'm assuming that Trevor must be correct.
I have been following the advice from a book called, "PHP 5/MySQL Programming
for the Absolute Beginner." I'm still reading this book yet, so I hate to
pronounce judgment, but from what I've seen regarding the issue of
configuration, this book might not be entirely correct. At least, not for an
absolute beginner. [And please don't forget that I am an absolute beginner
with PHP, so whatever I say about this book is probably not correct either--I'm
just going by my experience with the book and with the advice I've gotten from
others on the list]. I followed the configuration instructions in the book to
the best of my abilities, but in the end, I had to re-do everything, and
instead, follow the advice of someone that helped me from a list, just like you
folks. Also like you, he was very friendly and helpful, and he guided me
through the mess that was created when I followed the instructions in the book
regarding configuration. Anyway, the instructions in the book didn't work for
me, but the advice I got did work, as far as the initial problems I was having
with getting the phpInfo() command to work.
I'm including my comments about the book that I mentioned above only because
the title says that it's for absolute beginners. And I just think that it
might help someone else who is an absolute beginner like me to know that this
might not be the best book for a real absolute beginner. Then again, everyone
brings into a book the sum total of their life's experience, so anybody else
could get something very different out of the same book. I plan on finishing
this book, and I'm glad that I bought it, but as you can see, I've had to
depend heavily on this list (and the Apache list) to work out the kinks that
Iv'e run into. So I guess, this is kind of a review for other absolute
beginners out there, who are also trying to figure their way through setting up
PHP, MySQL and Apache. But, all else said, if I had to decide whether or not
to purchase this book over again, I would still buy it. So this is a mixed
review. The book has lot's of code samples and is well written. But the
book does say that getting PHP, MySQL and Apache set up is a real "headache,"
and suggests that the reader should get someone else to do it for them. A
statement like that in a how-to book, seems kind of weird to me.
But thank you for your help, everyone. I really do appreciate it. Once I've
finished going through the configuration process again, I'll add the code that
both Armando and Mike gave me, back into the program again, then I'll let you
know!
Thanks again,
Anthony
