passing variable on url

[drewbie]

if i make a link on one page for example:
echo "<a href=\"viewarchive.php?CAT=$myrow[Category]\">";

shouldnt the variable $CAT be made automatically for use in viewarchive.php? i try to echo it out in viewarchive.php, but nothing comes up! please help!

try:

echo "<a href=\"viewarchive.php?CAT=".$myrow['Category']."\">";

If this doesn't work, check and make sure Category is an index or the variable isn't empty to begin with.

still not working, and I already checked that the variable wasnt empty cause the mouseover reports the link correctly:
http://myserver/viewarchive.php?CAT=Boxing
and I have already passed a variable on another page this same way, im lost, any other suggestions?

[netizen]

echo $_GET['CAT'];

or

echo $HTTP_GET_VARS['CAT'];

place an echo at the top of the page to make sure the variable is being read. It should.

Are you calling this variable in a function or class? You may have to call global variables.

You aren't by chance redeclaring the variable anywhere in the code before its use?
