Yii2 Model validation is not working as expected - yii

Question

I am trying to validate a simple form in Yii2 framework.
validation method on model is -
/**
* {#inheritdoc}
*/
public function rules()
{
return array(
array('name', 'required'),
// ... other rules
);
}
When i try to make request it says -
array(1) { ["name"]=> array(1) { [0]=> string(21) "Name cannot be blank." } }
But the thing is i am sending name field in request ( POST ). But after providing name field , it gives an error.
If i do var_dump for request It shows me that name field is in there the request.
Here is the var_dump of request data and the validation error. -
array(1) { ["name"]=> string(6) "distro" } array(1) { ["name"]=> array(1) { [0]=> string(21) "Name cannot be blank." } }
Thank you in advance.

If I correct understanding your question, your problem is in your name of input.
In Yii2 ActiveRecord all data is in array of model name. for example:
Your models name is Users, when you using ActiveRecord your data must send like this to rules work on it:
{
'Users' => {
'username' => 'john_doe',
'fullname' => 'John Doe',
}
}
so change your html form input name to: model_name[field_name]
like this :
<input type="text" name="Users[username]">
