Group fieldtype support #76
Description
Description
I've tested around with a generic GroupTransformer.
The structure of $value would be: field:value|field2:value1,value2,value3|field3:value
Would need some logic for special cases though, like the entries fieldtype.
use Statamic\Importer\Transformers\AbstractTransformer;
use Statamic\Fields\Field;
use Statamic\Importer\Imports\Import;
use Statamic\Importer\Transformers\EntriesTransformer;
class GroupTransformer extends AbstractTransformer
{
public function transform(string $value)
{
$options = collect(explode("|", $value))->mapWithKeys(function ($item) {
list($key, $value) = explode(":", $item);
$fields = collect($this->field->get('fields'));
$field = $fields->where('handle', $key)->first();
if ($field['field']['type'] === 'entries') {
$newField = new Field($field['handle'], [ 'collections' => $field['field']['collections'] ]);
$transformer = new EntriesTransformer(
import: new Import(),
field: $newField,
config: [
'related_field' => 'slug',
'create_when_missing' => true
]
);
$value = $transformer->transform(str_replace(',', '|', $value));
}
return [$key => $value];
});
return $options->all();
}
}Maybe add some options like delimiter for multiple values and sub fields. In this example, show some config options, if the sub field is of type entries.
Could look like this – not tested and supports only one entries sub field, but should be possible with some enhancements:
public function fieldItems(): array
{
$fieldItems = [];
if ($this->entries) {
$collections = $this->entries->collections ?? Collection::all()->map->handle();
$fields = collect($collections)
->flatMap(fn (string $collection) => Collection::find($collection)->entryBlueprints())
->flatMap(fn ($blueprint) => $blueprint->fields()->all())
->unique(fn ($field) => $field->handle());
$fieldItems['related_field'] = [
'type' => 'select',
'display' => __('Related Field'),
'instructions' => __('importer::messages.entries_related_field_instructions'),
'default' => 'id',
'options' => $fields
->map(fn ($field) => ['key' => $field->handle(), 'value' => $field->display()])
->prepend(['key' => 'id', 'value' => __('ID')])
->values()
->all(),
'validate' => 'required',
];
$fieldItems['create_when_missing'] = [
'type' => 'toggle',
'display' => __('Create entry when missing?'),
'instructions' => __('importer::messages.entries_create_when_missing_instructions'),
'default' => false,
];
}
return $fieldItems;
}
