Why won't variable echo?

[affiliateian@gmail.com]

Just moved web hosts and noticed that this:

<?php echo "$f"; ?>

used to work when there was an ?f= in the URL like so:

http://www.mydomain.com/index.html?f=yes

Now it doesn't at the new host.

I want to echo out "yes" in the HTML.

Any ideas?

TIA.

register_global s will be off on your new host.

Either enable it using .htaccess (if possible) or change all references
to eg echo $_GET['f']. The latter is the better option but if your site
is full of global references then as a short term solution you'll need
to get register_global s enabled.

Thanks Chris, not sute how to enable register_global s but echo
$_GET['f'] worked! Thanks so much!

Luckily.

Either make sure sure ALL your values are initialiased ($f = '' etc...),
or keep register_global s off (preferably both ofcourse), so your script
won't have to deal with variable values that have been set by a user on the
Evil Net, but only by youself, or a validated/checked request from the
user. That way you're reaonably sure what your sript does, instead of
intorducing unpredictable, and potentially harmfull, variables.

Just at tip, for security reasons you may want to addslashes ie
addslashes($_GE T['f]) else people could inject into your site.

Addslashes won't do a thing here - except maybe screwup the output he's
echoing.

I have made it a habit to always write something like that as:

<?php echo '"' . $f . '"'; ?>

or

<?php echo $f; ?>

and I always say <?php


(single-double-single quotes)

He's relying on data from the url though, this could be dangerous
unless processed correctly
