laravel中的动态验证

Question

So I have a table with dynamic fields communication_type_id and communication_value. If user selects communication_type_id = 4 then communication_value should be phone number which is required and numeric if user select Communication_type_id =7 then communication_value should be required and email.How do I do this? I have done following till now but it does not seem to be checking the condition as I get "communication_value must be a valid email address" for both conditions:

  $validator = Validator::make($request->all(), [
        'name' => 'required',
        'client_addresses.*.address'=>'required',
        'client_addresses.*.city'=>'required',
        'client_addresses.*.state_province'=>'required',
        'client_addresses.*.country'=>'required',
        //Communication|
        'client_communications.*.communication_type_id'=>'required|numeric',

        //tag
        'tags.*.tag_id'=>'required',

    ]);

          foreach ($request->client_communications as $key=>$com) {
           // dd($com);
               if($com['communication_type_id']== "5")
               {

                 $validator = Validator::make($request->all(), [
                'client_communications.'.$key.'.communication_value' => 'required|numeric',
                 ]);
               }
               if ($com['communication_type_id'] == "7"){
                  $validator = Validator::make($request->all(), [
                 'client_communications.'.$key.'.communication_value' => 'required|email',
              ]);
          }


          }



      if ($validator->fails()) {

       return response()->json(['errors'=>$validator->errors()]);
       }

You can check it with getting posted data by $request variable, like this

$validator = Validator::make($request->all(), [
    'name' => 'required',

    //address

    'client_addresses.*.address'=>'required',
    'client_addresses.*.city'=>'required',
    'client_addresses.*.state_province'=>'required',
    'client_addresses.*.country'=>'required',

  'client_communications.*.communication_type_id'=>'required|numeric',

   //client tag

    'tags.*.tag_id'=>'required',

]);

if($request->communication_type_id == "4"){
  $validator = Validator::make($request->all(), [
  'client_communications.*.communication_value' => 'required|numeric|phone',
 ]);
}

if($request->communication_type_id == "7"){
  $validator = Validator::make($request->all(), [
  'client_communications.*.communication_value' => 'required|email',
 ]);
}

if ($validator->fails()) {
 return response()->json(['errors'=>$validator->errors()]);
}

If some other solution from laravel validation is appreciated otherwise this approach should well .
