When trying to create a page and passing $page-\>cover() (Being a files field) to one of its content props, this prop is empty ?!
Tipps appreciated …

I’m missing some context here. Where is this page created, via the Panel, programmatically? And where and when do you call `$page->cover()` then?

I got a migration script, loading in Kirby and then iterating over some pages, creating a set of pages using some of the page information, some other information from APIs etc.
Inside the loop, let’s say the original page is `$page` and the one to be created is created by `$otherPage->createChild()`:
```php
$otherPage->createChild([
'slug' => $page->slug(),
'template' => 'some-template',
'content' => [
'title' => $page->title(),
'cover' => $page->cover(),
// ...
)],
]);
```

You have to assign the value of the field, not the field object:
```auto
'content' => [
'title' => $page->title()->value(),
'cover' => $page->cover()->value(),
// ...
```
`$page->cover()` etc. return an object of the `Field` class, but we need a string here.
Please note that if you want to work with this page object after creation, you have to store it in a variable.
```auto
$newPage = $otherPage->createChild([
'slug' => $page->slug(),
'template' => 'some-template',
'content' => [
'title' => $page->title()->value(),
'cover' => $page->cover()->value(),
// ...
)],
]);
echo $newPage->cover();
```
In an echo context like the last line, a string is returned, because the magic method `__toString()` returns that string from the object.

Already tried that, too - doesn’t work (at least for me). Also tried with `toFile()->filename()` ☹
Will try again, though. Something smells fishy

To store the content of a files field, you have to store it in yaml format.
```auto
Data::encode($page->cover()->yaml(), 'yaml');
```
Should work.

it doesn’t work! 😮
I don’t get why your approach doesn’t work … `dump()`ing it gives the correct cover image …

This is correct, just tested it.
However, unless your code above only has a copy/paste issue, the syntax is not correct, the content array is not closed and the number of brackets is not correct either.
If that’s not the issue: Do you use the cover method from the Starterkit album model or something similar? If that is active, the code doesn’t work (but would then throw an error).

I typed in the example code, so the missing bracket is only there, not in the actual code - but how great of you distinguishing both cases!
`cover` is the name of the `files` field, nothing special there … this is the content file:
```nohighlight
----
Cover:
- eine-schwester_bastien-vives.jpg
----
```
… the actual code:
```php
$page = page('lesetipps')->children()->listed()->flip()->first();
$kirby->impersonate('kirby');
try {
$child = page('buecher')->createChild([
'slug' => $page->slug(),
'template' => 'book',
'content' => [
'cover' => Data::encode($page->cover()->yaml(), 'yaml'),
'title' => $page->title(),
'isbn' => $page->isbn(),
'shop' => $page->shop(),
'book_title' => $page->book_title(),
'book_subtitle' => $page->book_subtitle(),
'author' => $page->author(),
'illustrator' => $page->illustrator(),
'narrator' => $page->narrator(),
'translator' => $page->translator(),
'participants' => $page->participants(),
'page_count' => $page->page_count(),
'publisher' => $page->publisher(),
'age' => $page->age(),
'price' => $page->price(),
'binding' => $page->binding(),
'categories' => $page->categories(),
'topics' => $page->topics(),
'hasAward' => $page->hasAward(),
'award' => $page->award(),
'awardEdition' => $page->awardEdition(),
'leselink' => $page->leselink(),
'isAudiobook' => $page->isAudiobook(),
],
]);
// foreach ($page->files() as $file) {
// $file->copy($child);
// }
} catch (\Throwable $th) {
echo $th;
}
```
… and the blueprint portion is this:
```auto
fields:
cover:
label: Cover
type: files
query: page.images.filterBy('extension', 'in', ['jpg', 'jpeg', 'png'])
layout: cards
multiple: false
size: huge
image:
ratio: 2/1
cover: true
info: "{{ file.dimensions }} ({{ file.niceSize }})"
```

And what is the result in the newly created content file? What does it store as `cover`? Nothing at all? While all other fields are stored correctly?
And what do you get when you do this:
```auto
$page = page('lesetipps')->children()->listed()->flip()->first();
dump($page->cover());
```
The result should be a field object.

```nohighlight
Kirby\Cms\Field Object
(
[cover] => - >

… and for `$child` it gives this:
```nohighlight

That is all very weird.
If you do this in a fresh Starterkit, do you run into the same issue?
E.g in a Starterkit’s home template, I put this code for testing:
```auto
$p = page('photography')->children()->first();
$kirby->impersonate('kirby');
$newPage = $page->createChild([
'slug' => $p->slug() . '-' . microtime(),
'template' => 'some-template',
'content' => [
'title' => $p->title()->value(),
'cover' => Data::encode($p->cover()->yaml(), 'yaml')
],
]);
```

It gives this:
```nohighlight

Ah, sorry, in the Starterkit you first have to remove the cover method from the album model because it gets in the way.

Works as expected:
```nohighlight
Title: Trees

Cover:

Text:

This is really weird … I also removed all plugins, but nothing works.

Where are you executing your code?

It’s a separate script, loading Composer’s autoloader, initiating Kirby and then calling above code - but executing it from inside a template resulted in the same
I’m lost in this one, especially since it’s hard to debug.
