Make form submit button disabled when the form submit.
$ composer require light/yii2-lock-form=~1.0.2
Can can depends this in your assets:
if you depends on
yii2-bootstrap, you can uselight\widgets\LockBsFormAssetinstead. So can decrease the asset size.
class YourAsset extends AssetBundle
{
//..
public $depends = [
//your other depends
'light\widgets\LockFormAsset'
];
}
Or directly inject in the view:
use light\widgets\LockFormAsset;
LockFormAsset::register($this);
