Query that plucks tags from Structure field

Kirby 3 Solved ✅
1

I have a tag field inside a structure field. I’d like to autocomplete this field by querying all of the other pages. I’ve done this successfully many times with tags, but never from inside a structure field.

locations:
    type: structure
    fields:
        kiez:
            type: tags
            options: query
            query: page.parent.childrenAndDrafts.pluck("kiez", ",", true)
            max: 1

This does not work. How do I get the query to look inside the structure field?

I think you need a custom method to achieve this, pluck only works with single value fields or fields with comma etc. separated values.

I tried calling a custom site method which returns an array, but that didn’t work. like query: site.getItems where getItems basically is like:

$array = $this->someField()->yaml();
return A::pluck($array, ‚tags‘);

(Strange apostrophes due to me typing on iOS)

Did it much like you described here …

That should actually work, what is your Kirby version? And what’s in your blueprint?

Well, oddly it does now … Guess it was restarting PHP that must’ve worked :confused:

Hi there - thanks for this helpful start! I’m trying to achieve something similar but am struggling to implement.

I have a template called review with a structured field exhibitions. One of the yaml fields in the exhibitions structure is venue.

I would like a custom method that plucks all the values from exhibitions()->toStructure()->venue() of each page on the site using the review template.

How would I implement the above with e.g., the following custom site method:

<?php

Kirby::plugin('lettau/custom-site-methods', [
    'siteMethods' => [
        'venues' => function () {
            //  custom site method goes here ?
        }
    ]
]);

Solved like this (could be more elegant!):

<?php


Kirby::plugin('lettau/custom-site-methods', [
    'siteMethods' => [
        'venues' => function () {
            //  custom site method goes here
            $site = kirby()->site();
            $array = [];
            $reviews = $site->find('reviews')->children()->listed()->flip();

            // exhibitions yaml
            foreach ($reviews as $review) {
                $exhibitions = $review->exhibitions()->yaml();
                $venues = A::pluck($exhibitions, 'venue');
                $list = implode(', ', $venues);
                array_push($array, $list);
            }

            $array = array_filter($array);
            $array = implode(', ', $array);
            $array = explode(', ', $array);
            $array = array_unique($array);
            sort($array);

            return $array;
        }
    ]
]);

Much better - thanks!
