Filtering related_contentobject_array

Monday 08 September 2003 7:11:27 am

How does one go about filtering the contents of related_contentobject_array.

Many of my articles contain a number of images that are inserted using embedded objects. ez3.1-1 (svn 2703) automatically adds embedded objects to the related objects array.

When displaying a list of related objects, my images are also included. I don't want this. How do I go about ensuring that only related objects of a specific class are displayed?

Ideally, I would be able to use fetch(), but there doesn't seem to be a way to do this.

<div class="related">
<ul>
{section loop=$node.object.related_contentobject_array}
<li><a href={concat("/content/view/full/",$:item.main_node.node_id)|ezurl}>{$:item.name}</a></li>
{/section}
</ul>
</div>

One of the options is to use a {section show=...} but this isn't ideal. Why? Because the related objects div shows up if there are only images in my article and it ends up looking a bit daft.

Any suggestions out there?

Thanks for the idea... It will still have the same problem as the {section show=...} though AFAIK.

The problem is that I don't want to display the <div> if there are no related objects. The <div> displays as a box on the page. Thye box has a heading "Related items"

I only want to display the box (div) if there are actually any related items. The problem is that the images in my articles are considered to be related items.
I can filter them out of the results using a {section show=...} or {switch}, but if there are no other relevant items, I get the "related items" box being displayed without any items in it.

That is why I would like to filter the array before I check to see if there is anything relevant.

Hi Paul,

I thought about that. The problem is what do I use to determine whether I show or not. Up until now I have been using {section show=$node.object.related_contentobject_array}

The problem there is that it will show if there are *any* related objects (including the images).

My full source code looks like:
{section show=$node.object.related_contentobject_array}
<div class="related">
<ul>
{section loop=$node.object.related_contentobject_array}
<li><a href={concat("/content/view/full/",$:item.main_node.node_id)|ezurl}>{$:item.name}</a></li>
{/section}
</ul>
</div>
{/section}

Hi Paul,

That won't solve the problem. Take the following case:
I have an article with one embedded image.

Now, I don't want to display any images in my list of related objects.

Using the code you supplied in the above example, I will still end up with the following HTML:

<div class="related">
<ul>
</ul>
</div>

I need a solution that will eliminate the <div> and <ul> tags too.

Ok, my code may have not worked exactly for you but it should be modifiable to your use. It sounds like you need to examine whether there are images in your array and display only those...

Look at the template documentation for how to program this.
