|
18
|
|
|
* |
|
19
|
|
|
* ```php |
|
20
|
|
|
* 'columns' => [ |

|
* // ... |
|
22
|

|
|
* 'checked' => $model['value'] == 2 |
|

|
* @var array|\Closure the HTML attributes for the radio buttons. This can either be an array of |
|
45
|
|
|
* attributes or an anonymous function ([[Closure]]) returning such an array. |
|
46
|
|
|
* |
|
47
|
|
|
* The signature of the function should be as follows: `function ($model, $key, $index, $column)` |
|
48
|
|
|
* where `$model`, `$key`, and `$index` refer to the model, key and index of the row currently being rendered |
|
49
|
|
|
* and `$column` is a reference to the [[RadioButtonColumn]] object. |
|
50
|
|
|
* |
|
51
|
|
|
* A function may be used to assign different attributes to different rows based on the data in that row. |
|
52
|
|
|
* Specifically if you want to set a different value for the radio button you can use this option |
|
53
|
|
|
* in the following way (in this example using the `name` attribute of the model): |
|
54
|
|
|
* ```php |
|
55
|
|
|
* 'radioOptions' => function ($model, $key, $index, $column) { |
|
56
|
|
|
* return ['value' => $model->attribute]; |
|
57
|
|
|
* } |
|
58
|
|
|
* ``` |
|
59
|
|
|
* @see \yii\helpers\Html::renderTagAttributes() for details on how attributes are being rendered. |
