yii2- saving datas to multiple rows from one form - yii2

Question

I am so new to the yii2 framework, I have a form that I want to save each party score to correspond to each party abbreviation. I don't know how to go about it. here is my code.
the model -
namespace app\models;
use Yii;
/**
* This is the model class for table "announced_pu_results".
*
* #property int $result_id
* #property string $polling_unit_uniqueid
* #property string $party_abbreviation
* #property int $party_score
* #property string $entered_by_user
* #property string $date_entered
* #property string $user_ip_address
*/
class AnnouncedPuResults extends \yii\db\ActiveRecord
{
/**
* #inheritdoc
*/
public static function tableName()
{
return 'announced_pu_results';
}
/**
* #inheritdoc
*/
public function rules()
{
return [
[['polling_unit_uniqueid', 'party_abbreviation', 'party_score', 'entered_by_user', 'date_entered', 'user_ip_address'], 'required'],
[['party_score'], 'integer'],
[['date_entered'], 'safe'],
[['polling_unit_uniqueid', 'entered_by_user', 'user_ip_address'], 'string', 'max' => 50],
// [['party_abbreviation'], 'string', 'max' => 4],
];
}
public function getPollingUnit()
{
return $this->hasOne(PollingUnit::className(), ['id' => 'polling_unit_uniqueid']);
}
/**
* #inheritdoc
*/
public function attributeLabels()
{
return [
'result_id' => 'Result ID',
'polling_unit_uniqueid' => 'Polling Unit Uniqueid',
'party_abbreviation' => 'Party Abbreviation',
'party_score' => 'Party Score',
'entered_by_user' => 'Entered By User',
'date_entered' => 'Date Entered',
'user_ip_address' => 'User Ip Address',
];
}
}
the controller action is create ---
public function actionCreate()
{
$model = new AnnouncedPuResults();
if ($model->load(Yii::$app->request->post()) ){
//&& $model->save()) {
$post = yii::$app->request->post('AnnouncedPuResults');
$party_score = $post['party_score'];
$count = count($party_score);
for($i =0 ; $i < $count; $i++) {
$model->party_abbreviation = $post['party_abbreviation'];
$model->polling_unit_uniqueid = $post['polling_unit_uniqueid'];
$model->entered_by_user = $post['entered_by_user'];
$model->date_entered = $post['date_entered'];
$model->party_score = $post['party_score'];
$model->save();
}
return $this->redirect(['view', 'id' => $model->result_id]);
}else{
return $this->render('create', [
'model' => $model,
]);
}
}
this is the partial view form for the action create----
