HowTo see if article has an image

Sunday 10 August 2003 8:29:29 am

I want to test if an article has an article in it.
If it do not I want to put a standard image

{section name=show_image show=null($content_version.data_map.thumbnail.id)}
<img src={"standard.gif"|ezimage} width="190" height="136" />
{section-else}
{attribute_view_gui attribute=$content_version.data_map.thumbnail image_class=medium}
{/section}

I'm testing to see if thumbnail_object has an id. But it seems like it the thumbnail_object always has an ID, even if I dont put an image....

Is there a "correct" way to test if the article has an image?

Hey Selmah,

I tried this:
{section show=is_object($content_version.data_map.thumbnail)}
{attribute_view_gui attribute=$content_version.data_map.thumbnail image_class=medium}
{section-else}
<img src={"informe.gif"|ezimage} width="190" height="136" />
{/section}

But still it won't work so I tested what the operator "is_object" is returning as value for a new article without an image with:

{default content_version=$node.contentobject_version_object}
{is_object($content_version.data_map.thumbnail)}

and it turned out that the value is 1 (true).
And this should be 0 (false) becasue there is no image attached to the image :(

{$:item.data_map.thumbnail.content}

This is not working for me either.

I tried to echo the value for different article (with and without image) and for all of them, the value of content is "null". So the value is not set.

What is happening here?
