YII send array or array of array from view to controller action via form post

I have one question with two different type of data.

I have a view in Yii, which has got a form control. I want to send an array, and an array of array to the controller, to my create action.

The array is : $arraySons = ('albert','francis','rupert');

The array of array is $arrayFather = ('1'=>array(6,7,8));

I must use some control, so the form will post it in $_POST?... or this can't be done and I must use JavaScript?

You can create your form as in the answer of @crafter. I just wirte more details:

<input type="hidden" name="sons[]" value="albert">
<input  type="hidden" name="sons[]" value="rupert">

and so on

and then for the fathers you would do something similar:

<input  type="hidden" name="father[1][]" value="6">
<input  type="hidden" name="father[1][]" value="7">
<input  type="hidden" name="father[1][]" value="8">

But if the user does not need to see the data, you could maybe prepare a JSON object with the data, and post it in 1 field, which seem much easier for me

<input  type="hidden" name="father" value="<?= json_encode($arrayFather); ?>">
<input  type="hidden" name="sons" value="<?= json_encode($arraySons); ?>">

and then in your action you can get the data from post and decode it with json_decode

$myArrayFather = json_decode($_POST['father']);
$myArraySons = json_decode($_POST['sons']);

Normally, in HTML forms you can create an array by having more than one field with the same name, and a array notation.

<input name="sons[]">
<input name="sons[]">

When you submit the form $_POST['sons'] will be an array, and can be handled as follows :

foreach ($_POST['sons'] as $son) {

    echo 'Son of the father is '.$son."\n";

}
