Clay Pereira	Thursday 19 February 2004 4:12:48 pm How do and if null case Example: IF $node.object.data_map.author <> Null <h3>By:{attribute_view_gui attribute=$node.object.data_map.author}</h3> else <h3>No Author</h3> Sorry For the newbie Question. Can't figure out how to check variables.
Clay Pereira	Thursday 19 February 2004 4:43:50 pm I don't know if I am one the right track... This is what I have tried so far.... {switch match=$node.object.data_map.author.data_text} {case match=""} <h3>By:{attribute_view_gui attribute=$node.object.data_map.author}</h3> {/case} {/switch}
Clay Pereira	Thursday 19 February 2004 5:28:35 pm I tried this too.... {section show=$node.object.data_map.author\|null( ) <h3>By:{attribute_view_gui attribute=$node.object.data_map.author}</h3> {/section}
Clay Pereira	Thursday 19 February 2004 6:22:29 pm Well I figured it out after all. Here is what I did. {section show=ne($node.object.data_map.author.content)} <h3>By:{attribute_view_gui attribute=$node.object.data_map.author}</h3> {/section}
Marko Pohl	Friday 20 February 2004 12:41:28 am have a look at this: http://ez.no/ez_publish/documentation/development/libraries/ez_template/operators/control_structure_handling But i think this is only suitable for 'tiny' conditions...
