Filter taxonomies

[tobinski]

I try to display a list of taxonomies with the following requirements:

• The taxonomy has at least one entry
• The entry has to be in another taxonomy

The current usecase is a list of categories for a festival. Each event at the festival can have one or more category and each event is assign to an edition of the festival. I want to display all cats with at least one entry for the current edition.

The following sniped should work in my eyes, but it doesn't.

{{ taxonomy from="tags"  }}
        {{ entries taxonomy:edition="2022" as="e"}}
            {{ if e | count > 0}}
                {"title": "{{title}}","slug":"{{slug}}"}{{if !last}},{{/if}}
            {{ /if }}
        {{/entries }}
{{/taxonomy}}

The filter taxonomy:edition is not applied correctly. The docs state "You're free to use filtering or sorting parameters on the entries pair" but that does not work or I apply it wrong. Any idea how I do this?

The only way I could make it work was to use a blade partial.

<?php
    $output = [];
?>
@taxonomy("tags")
        <?php
            $a = $term['entries']->WhereIn("edition", "2022")->count();
            if($a != 0) {
                $output[] = "{'title': '".$term['title']."','slug':'".$term['slug']."'}";
            }
        ?>
@endtaxonomy
[{!! implode($output, ",")!!}]
