Hello.

I want to display the content of a xml area. But the field mustn't be shown, if it has no content. I use this code:

{if $node.object.data_map.anwendung.has_content}
    <b>{"Anwendung"|i18n("design/plain/full")}</b><br />
    {attribute_view_gui attribute=$node.object.data_map.anwendung}
{/if}

There is no content in the xml area but my headline

<b>{"Anwendung"|i18n("design/plain/full")}</b>

is shown anyway... what am I doing wrong?

I's using eZ 3.7.6

Hi Philip
try with

{if $node.object.data_map.anwendung.content.is_empty|not}
   <b>{"Anwendung"|i18n("design/plain/full")}</b><br />
   {attribute_view_gui attribute=$node.object.data_map.anwendung}
{/if}

Hi.

thank you for your reply. I tried this some time before and it doesn't work, too.
I made some debugging with

{$node.data_map.anwendung|attribute(show)}

to get closer to the problem. Curious is that the xml area is empty. I pressed CTRL + A to mark all the text in the xml area and deleted it, to be sure, that there is no content in it.

But the attribute-list shows the following:

content 	object[ezxmltext] 	Object
>is_empty 	boolean 	false
has_content 	boolean 	true

But there is no content in it.... any ideas?

Thank you,
Philip

Hi!

Try this code..

{if eq($node.object.data_map.anwendung.is_empty)}
   <b>{"Anwendung"|i18n("design/plain/full")}</b><br />
   {attribute_view_gui attribute=$node.object.data_map.anwendung}
{/if}

Cheers,

Leandro

Hi.

Changes nothing. I don't think the code is wrong (all the codes in this thread), I can't understand why "has_content" is true or "is_empty" is false - there is no content in die xml area...

OK, I found out some more. The code is correct. When I disable the Online Editor and save the template, there will be displayed nothing - like it should be.
But when I save and the Online Editor is enabled, it will be displayed...

Just tried it on stable/3.7 and OE 4.1.1 - everything is ok, has_content is false, content.is_empty is true.
I tried it with 'article' class and 'body' attribute.

ps. Which OE version are you using?

Yes, you're right. After I've written my last post, I tried it with a newer Version of ezdhtml and now it works.

Thank you all for your help.
