Hi im trying to display my “klantennaam” in my “Overzicht” Form but it keeps giving me an error that my class is not found.

I tried calling it with Mapping.

    <?= $form->field($model, 'Klanten_id')->dropDownList(ArrayHelper::map(Klanten::find()->select(['klantennaam','ID'])->all(), 'ID', 'displayName'),['class' => 'form-control inline-block']); ?>

I have an “Overzicht” Model that gets my foreignkey.

 public function getKlanten()
    {
        return $this->hasOne(Klanten::class, ['ID' => 'Klanten_id']);
    }

And that workss good but i need it working for my Form.

Hopefully this is an easy fix!

Missing use statement?

Error
Class “Klanten” not found.

Still vague for me.
use statement of what??? Arrayhelper or Klanten. and where should i create the class if it doesn’t exist?

i used an YT tutorial and didn’t miss a thing.

This tut is for something else its actually,
What im trying to do is showing foreign relations in _Form

So that i can chose names from foreign table instead of having to fill the id every time like in the video

You probably defined Klanten i app/models, frontend/models or backend/models.

And as said before, do not post images, use plain text (click preformatted text in the editor).
