Question

How to set attribute labels when using dynamic model in yii2 structure?

Here is my code below:

$model = DynamicModel::validateData(compact('name','shipping'), [
        [['name','shipping'], 'required'],
    ]);
    if ($model->hasErrors()) {
        // validation fails
      //  }
    } else {
        //validation true
    }

Answer 1

As an easy way out, just set up separate verification messages for the required attributes:

$model = DynamicModel::validateData(compact('name','shipping'), [
    [['name'], 'required', ['message' => Yii::t('app', 'Name is required for this form.')]],
    [['name'], 'required', ['message' => Yii::t('app', 'Shipping address is required for this form.')]],
]);

And use labels when displaying the DynamicModel field:

echo $form->field($model, 'name')->textInput()->label(Yii::t('app', 'Name')); 
echo $form->field($model, 'name')->textInput()->label(Yii::t('app', 'Shipping address'));

Answer 2

I like to expand the component, for example:

class DynamicModel extends \yii\base\DynamicModel {

    protected $_labels;

    public function setAttributeLabels($labels){
        $this->_labels = $labels;
    }

    public function getAttributeLabel($name){
        return $this->_labels[$name] ?? $name;
    }
}

And to use it:

$attributes = ['name'=>'John','email'=>'[e-mail]'];
$model = new DynamicModel($attributes);
$model->setAttributeLabels(['name'=>'Name','email'=>'E-mail']);
$model->validate();
