Grav: Twig page collections - add possibility to make OR conditions

[daspete]

Hi there,

i just tried to create a collection with multiple category taxonomies in Twig

{% set collection = page.evaluate([{
    '- @taxonomy.category': 'list',
    '- @taxonomy.category': 'page'
}]) %}

But it seems, this just works, when it is set in the page header.

content:
    items:
        - @taxonomy.category: list
        - @taxonomy.category: page

But the downside of this way is, that i would have to add this lines to every page....

Is there another way to get a "global" collection? The reason is, i want to have a navigation, which just gives me the links to pages with the categories "list" OR "page"

i think, i found a way to combine multiple collections in twig, but it feels a bit hacky... :) maybe anyone knows a nicer solution?

{% set collection = page.evaluate([{
    '@taxonomy.category': 'list'
}])|merge(page.evaluate([{
    '@taxonomy.category': 'page'
}])) %}

Collections are essentially just arrays of pages, so your 'hacky' way is really not that hacky, it's just using twigs merge filter to join two arrays. That's not a bad solution.

We really don't have a sophisticated query language for handling or relationships, this is something we would like to improve going forward, but for now your solutions is fine :)

I'm not sure how we implemented this, but I think that you can also do:

content:
    items:
        - @taxonomy.category: [list, page]

Not sure if it was using AND or OR. But its worth to try if it does the trick. :)

Also {% set pages =taxonomy.findTaxonomy({'category':['list','page']},'or') %} ?
