You're talking about this? yiiframework.com/doc-2.0/… If so, that seem to have $options where you can set the default selection. – Argali

i already gone through this doc, if anyone find the attribute name, then i want a demo? – Unreligious

In my test the radio button is normally preselected (ther first one) just a minor the 2 is better if you code '2' like the first. – Pairoar

The default radio button (pre selected) is normally the first radio button. In my test ithe firts is always already cheked. And second point in your code the value 2 is not with quotes. I hope thi is more clear .. – Pairoar

Answer 1

The preselected values are taken from $model->config. That means that you should set that attribute to the value that you want preselected :

$model->config = '1';
$form->field($model, 'config')->radioList([
    '1' => 'Automatic Entry',
    '2' => 'Manual Entry',
]);

The relevant doc for this is in the ActiveForm class.

Answer 2

if you want to use default value of radio, you can use following codes:

<?php $model->isNewRecord==1 ? $model->config=1:$model->config;?>
<?= $form->field($model, 'config')->radioList(
    [
         '1'=>'Automatic Entry',
         '2'=>'Manual Entry'
    ])->label('Barcode/Book No Generation'); 
?>

Answer 3

You have to set 'config' attribute.

$model->config = 1;

You'll have first radio button selected when form is loaded.

tarleb is right.

Long shot in the dark since I'm not awfully familiar with yii2, but based on the documentation you should be able to do something like this.

$form->field($model, 'config')->radioList([
          '1'=>'Automatic Entry',
          '2'=>'Manual Entry',
    ], [
        'item' => function ($index, $label, $name, $checked, $value) {
            return Html::radio($name, $checked, ['value' => $value]);
        },
    ]);
// [...]
ActiveForm::end();
