Laravel array validation in Form Request

Question

I can't validate a field, which contains array elements, in Form Request class. Rules method:

public function rules()
{
    return [
        "state" => 'required',
        "state.0" => 'required',
        "state.*" => 'required',
    ];
}

There is an array in request->all()

"state" => array:1 [
  0 => ""
]

Zero element is empty. But validation is successful. What am I doing wrong?

It's empty but it exists. What happens if you add "state.0" => 'required|min:1'? — Mjh

Are you calling the rules into your controller and outputting an error message if it fails to pass? — Option

@Mjh, required should be more than enough to not allow an empty field to pass through. — Option

In order to handle the dynamic fields, you will need to loop through all the posted "items" and add a rule for each.
Here is an updated method demonstrating this:

public function rules() {
    $rules = [
          'state' => 'required',
         ];
    foreach($this->request->get('state') as $key => $val) {
        $rules['state.'.$key] = 'required';
    }
    return $rules;
}
