Carlos Revillo	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.
Marcin Drozd	Friday 26 May 2006 3:25:13 am Hi Carlos You can use a template operator is_set( target ) where target = ezhttp('var','get'); and var is name of your get variable from url see more: http://ez.no/doc/ez_publish/technical_manual/3_7/reference/template_operators/variable_and_type_handling/get_type http://ez.no/doc/ez_publish/technical_manual/3_7/reference/template_operators/variable_and_type_handling/is_set http://ez.no/doc/ez_publish/technical_manual/3_7/reference/template_operators/variable_and_type_handling/is_unset http://ez-publish.pl
kracker (the)	Wednesday 31 January 2007 7:40:34 am 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? //kracker <i>sage francis - sick of waiting tables - i apologize</i> Member since: 2001.07.13 \|\| http://ezpedia.se7enx.com/
