If-then-else and is_empty

Thursday 28 April 2005 12:16:33 am

Hi,

I have two sorts of articles in one "News" folder. I take the 4 most recent and put their title (or name) at the frontpage(and a "Read more" link) .

The problem is that article type 1 has a title and article type 2 has no title but a name (yes, it does make sense :) ).

So my problem is that when I use "is_empty" on a title it works fine, however, when there is no title (only a name) I don't get the {section-else} printed.
Look at this code:

{section show=$:item.object.data_map.title.content.is_empty|not}
 {attribute_view_gui attribute=$:item.object.data_map.title};
{section-else}
 {attribute_view_gui attribute=$:item.object.data_map.name};
{/section}

The "is_empty" part is my problem. I cannot test if the title is empty (or full) when an article has a name only...

Can I switch the "is_empty" with "does_exists" or something like that? Any other suggestions are very welcome :)

Thanks in advance!

Thanks for suggestion, I tried:
{section show=$:item.object.data_map.title.is_valid}

and
{section show=$:item.object.data_map.title.content.is_valid}

but it goes to {section-else} 100% of the time.

Any other suggestions :) ?

That sounds like a great idea!, but I don't know how to create a "name pattern". Would you have any more information?

Thanks again :)

Hi, found the name pattern. I also search for help using this attribute, not much luck with examples.

I currently have article class (default) with
Object name pattern: <short_title|title>

Do you have any suggestion how I add "name" in here? My intuition says something like <short_title|title|name=title>...

Would you have a link to documentation regarding "object name pattern" and/or "is_empty/is_valid" attributes?

Thanks

Thanks and thanks

Hi

Try to use the "has_content" instead (http://www.ez.no/ez_publish/download/changelogs/ez_publish_3_4/datatype_changes )

You could also try:

is_set($:item.object.data_map.title)
