Variable exists

Thursday 25 May 2006 2:12:34 am

Hi. Is there any way to know if a variable is defined?.

I'll try to explain it better.

I have a node. Path_identification_string for the node is ".../node"

But, sometimes, i have urls like "../node?var=x" and so on.

How can i know if i have params in my url or not?.
I was thinking in something like if is_defined(var) or something like that...

Thanks.

I tried Marcin's approach for testing if a variable exists with this code,

{if is_set( ezhttp( 'print', 'get' ) )}x{else}z{/if}

I also read a similar thread,
<i>http://ez.no/community/forum/general/how_to_test_for_existance_of_variable</i>

Yet this approach seems to throw a this error,

Error: eZTemplate:ezhttp    Jan 31 2007 10:31:16    Unknown get variable 'print'

Is it possible to test for a variable in template language in this way without throwing an error?
