How to modify a field in a structure and return a translated string?

The CMS Questions

I created a structure from an array like this:

$fields['mail'] = [
  'type' => 'email',
  'label' => [
    'en' => 'Mail Address',
    'de' => 'Mail Adresse'
  ]
];

$fields['bla'] = [
  'label' => 'Not Translated Bla'
]

$s = new Structure($fields);

Now I’m trying to run map, check if label is an array and try to select the right language key, if present and replace label with the translated string :

$s = $s->map(function($field){
  $field->label = // set label to string with the right translation, or the fallback
  return $field;
});

dump($s->toArray());

For one, I can’t set the label. $field->label = 'test' and then I’m not sure how to approach the translation the best. I checked the kirby source and how I18n::translate works, but it didn’t click. Any help would be appreciated! Thanks

PS: I guess I don’t have to use new Structure and just use the $fields array, but I want to understand the Kirby way of doing it.

Since the properties are protected, you cannot modify them.

So is there another way to solve this?

What is your use case?

In general I want to learn how to use Kirby’s methods to do these kind of things (else I would use laravels collect() to manipulate an array)

The specific use case is to turn the example array above into a structure, maybe filter it, manipulate it and translate one property (that’s the example with ->map().

I guess using the example above, I want to turn this:

$fields['mail'] = [
  'type' => 'email',
  'label' => [
    'en' => 'Mail Address',
    'de' => 'Mail Adresse'
  ]
];

$fields['bla'] = [
  'label' => 'Not Translated Bla'
]

to this:

$fields['mail'] = [
  'type' => 'email',
  'label' =>  'Mail Adresse'
];

$fields['bla'] = [
  'label' => 'Not Translated Bla'
]

using Kirby’s Collection/Structure and I18n Methods and Helpers.

(Hope that makes sense :))

If you use a collection instead of a structure, you can do it like this:

$s = new Kirby\Cms\Collection($fields);

$s = $s->map(function($field) {
    $field['label'] = 'test';
    return $field;
});

Thank you so much! This worked!


$fields['mail'] = [
  'type' => 'email',
  'label' => [
    'en' => 'Mail Address',
    'de' => 'Mail Adresse'
  ]
];

$fields['bla'] = [
  'label' => 'Not Translated Bla'
]

$s = new Kirby\Cms\Collection($fields);

$s = $s->map(function($field) {
    $field['label'] = I18n::translate($field['label'],$field['label']);
    return $field;
});

Two things that I noticed:

  1. Collection turns an associative array into an indexed one (you are losing the named array keys when converting back (unless I overlooked something)

  2. the I18n::translate method takes an array with the language code as keys as in the above example with label. https://getkirby.com/docs/reference/tools/i18n/translate
