I have a controller generated by Gii. I modify the behaviors to be like this:
public function behaviors()
{
return [
'verbs' => [
'class' => VerbFilter::className(),
'actions' => [
'delete' => ['post'],
],
],
'access' => [
'class' => AccessControl::className(),
'rules' => [
[
'allow' => true,
'roles' => ['@'],
],
],
],
];
}
When I fill the form and submit it, sometimes I get an error
Bad Request (#400) Unable to verify your data submission
But if I click on back button in my browser and re-submit again the form with the same value it will be okay an submitted successfully.
I have been searching in google and stackoverflow, many of them say that the problem is on CSRF Token. But in my layout I've put <?= Html::csrfMetaTags() ?> and in my form there is <input type="hidden" name="_csrf" value="...">
Anyone here can help me to solve this? And explain this why does it happen?
