[solved] Article category count for accurate descriptions
I’d appreciate an additional pair of eyes on the following, any advice is most welcome and gratefully received, especially if it saves me some work and reduces the work that Textpattern has to do.
Consider the following 4 article categories:
- apple
- banana
- cherry
- damson
A section has articles, displayed using an article list, and each article has zero, one or two of the above categories. I’d like to correctly describe the article list depending on what is being viewed. For example, where an article list has 4x articles categorised with ‘apple’ and 1x with ‘banana’:
apples and banana
Where there are more than two categories, I want to use commas and still be grammatically correct, like this:
apples, banana and damsons
…or the full-house:
apples, bananas, cherries and damsons
I’ve figured out how to display each fruit with one and more-than-one articles, and also to omit it where there are zero articles; that’s pretty straightforward. With my four categories, each with 3 states (zero articles, one article, more than one articles), I have 3×3×3×3 potential outcomes, giving me 81 things to take into account. I can, with lots of copy + pasting, build a large, nested query tree to cover all 81 eventualities. It’s likely to be a big block of markup, and I’m comfortable writing it, but is there a more efficient way that I could use instead?

Hi Pete,
if you’ve
figured out how to display each fruit with one and more-than-one articles, and also to omit it where there are zero articles
the rest is pretty straightforward:
<txp:variable name="cocktail" value='your_apple_item, banana_item, cherry_item, damson_item' />
<txp:php>
if($items = array_filter(do_list(parse('<txp:variable name="cocktail" />')))) {
$end = array_pop($items);
echo $items ? implode(', ', $items).' and '.$end : $end;
}
</txp:php>Edit: shortened the code.
Edit: a one-liner, just for fun:
<txp:variable name="cocktail" value='your_apple_item, banana_item, cherry_item, damson_item' />
<txp:etc_query data="{?cocktail||do_list.array_filter.implode(, |$).strrev.explode( ,|$|2).implode( dna |$).strrev}" />Last edited by etc (2014-01-05 16:32:51)

Oleg, thank you very much. You’ve made a cold and weary Englishman much happier.
Note to self: learn PHP.
