Merging two category types into one list?

phiw13 · 2017-02-22 12:27:16

I was looking at outputting the combination of article and image categories in one list. The following does not work:

<txp:category_list type='article, image' wraptag='ol' break='li' sort='title desc' />

Any reason why that would not be possible? Same issue with <txp:category /> and <txp:if_category />, btw.
I ended up building my list more manually:

<ol>
<txp:category_list type='article' break='li' sort='title desc' />
<txp:category_list type='image' break='li' sort='title desc' />
</ol>

~~~

While investigating this, I found out that <txp:category type='' /> actually works — that seems undocumented. That was a sort of blessing.
My default page template:

<!-- stuff-->
<txp:if_category> <!-- do something for categories -->
<txp:else />
<!-- other stuff -->
<ol>
<txp:category_list type='article' break='li' sort='title desc' />
<txp:category_list type='image' break='li' sort='title desc' />
</ol>
</txp:if_category>

The links for the image category would not work correctly, loading the default “front“ page instead of the category page. As soon as I changed my opening category tag to <txp:category type=''>, those links started working. Which is logical of course, the default value for type being article.

Edit: correct some markup error, thanks for the pointer GugUser.

No I haven’t considered that; honestly. A bit of overkill for my humble needs in this case. But I was more puzzled by the fact that the type attribute only supported one value.

I don’t understand what you are doing with…

<txp:category>
<txp:else />
<txp:category>

Should it be <txp:if_category>?

You are correct sir! I’ll update the snippet in my OP.

I guess it’s because of homonyms, which are not allowed within a type, but possible across two types. If you have both article and image categories called sunrise, and want to display their subcategories tree, this standard construction will not work:

<txp:category_list children="0" parent="sunrise" exclude="sunrise" type="article, image" wraptag="ul" break="li">
    <txp:category title="1" link="1" />
    <txp:category_list children="0" parent='<txp:category />' exclude='<txp:category />' wraptag="ul" break="li">
        <txp:category title="1" link="1" />
    </txp:category_list>
</txp:category_list>

This could somehow be amended, but I think that mixing different types of objects is generally error-prone.

Ok, yeah I can see that being a problem indeed. Thanks for explaining.
