Where to put the options for a listBox

Yii 2.0 General Discussions

Just started with Yii2 and want to know where you would define the options for a listBox in a form that I created with gii.

So in form_.php

I now do this:

<?php

use yii\helpers\Html;

use yii\widgets\ActiveForm;

/* @var $this yii\web\View */

/* @var $model app\models\Lotto */

/* @var $form yii\widgets\ActiveForm */

// options for listBox

$items[]="No" ;

$items[]="Yes";

$items[]="MayBe";

$items = array_combine($items, $items);

?>

<div …>

<?php $form = ActiveForm::begin(); ?>

<?= $form->field($model, ‘choose’)->listBox($items) ?>

<div class="form-group">

    &lt;?= Html::submitButton(&#036;model-&gt;isNewRecord ? 'Create' : 'Update', ['class' =&gt; &#036;model-&gt;isNewRecord ? 'btn btn-success' : 'btn btn-primary']) ?&gt;


&lt;/div&gt;





&lt;?php ActiveForm::end(); ?&gt;

</div>

It works. Can I leave it like this or should I put $items in the controller / model ?

and how would I do that?

In my case, I like to define the items in my model class like this :




class MyClass extends ActiveRecord

{

  const CHOOSE_YES = 1;

  const CHOOSE_NO = 0;

  const CHOOSE_MAYBE = 2;


  public static function getChooses()

  {

      return [

          self::CHOOSE_YES => Yii::t('app', 'Yes'),

          self::CHOOSE_NO => Yii::t('app', 'No'),

          self::CHOOSE_MAYBE => Yii:t('app', 'Maybe')

      ];

  }

    

  public function getTextChoose()

  {

      $items = self::getChooses();

        

      return array_key_exists($this->choose, $items) ? $items[$this->choose] : null;

  }


  public function rules()

  {

    return [

      ...

      ['choose', 'in', 'range' => array_keys(self::getChooses())]

    ];

  }


}

Like this you can use this code in all views




<?= $form->field($model, 'choose')->listBox(MyClass::getChooses()) ?>

Or in the gridView widget :




...

[

  'attribute' => 'choose',

  'value' => return function($model, $key, $îndex, $column) {

    return $model->getTextChoose();

  },

  'filter' => MyClass::getChooses()

]

Thx for the example that helps!

I’ll move the options to my model.
