来自db的Yii2表单字段

Question

I would like to implement a solution where the field types of a form are coming from database. My form is an ActiveForm with a model.

I was adding the following to db:

formfield: textInput

and this to the form:

<?= $form->field($model, 'rgw')->{$model->rrgw->formfield}(['maxlength' => true]) ?>

this is the only way it works, and only for textinput. As soon as I delete (['maxlength' => true]) it's not working anymore and I get the error:

Getting unknown property: yii\bootstrap\ActiveField::textInput

Furthermore, if I want a checkbox or something else, (['maxlength' => true]) is not wanted, right? So I was trying to add () to the db, so like this:

formfield: textInput()

I'm still getting error:

Getting unknown property: yii\bootstrap\ActiveField::textInput()

How can I get rid of () part in yii and move this to the db? Can you please point me to the right direction? Many thanks for your help!

Answer 1

textInput() and checkbox() are methods, so you need to use () to indicate that you want a methods instead of property.

<?= $form->field($model, 'rgw')->{$model->rrgw->formfield}() ?>
