保存复选框列表的选项时遇到问题。当我选择多个选项时，出现错误

答案无效

，当我选择一个选项时，它允许我发送数据，但我得到错误

htmlspecialchars（）预期参数1为字符串，数组给定

'Answer' => [
    [
        'answer' => '37',
        'question_id' => '34',
    ],
    [
        'answer' => '40',
        'question_id' => '35',
    ],
    [
        'answer' => [ //selected options from checkboxlist
            '43',
            '46',
        ],
        'question_id' => '36',
    ],
    [
        'question_id' => '37',
        'answer' => '42',
    ],
],

控制器

public function actionQuestionnaire($id)
{
    ...... 
    ........

    $count = count(Yii::$app->request->post('Answer', []));

    $answers = [new Answer()];

    for($i = 1; $i < $count; $i++) {
        $answers[] = new Answer();
    }

    if (Model::loadMultiple($answers, Yii::$app->request->post()) && Model::validateMultiple($answers)) {

        foreach ($answers as $answer) {
            $answer->save(false);
        }
        return $this->redirect('index');
    }
    return $this->render('create', [
        'model' => $model,//question data
        'answer' => $answer,
        'dataProvider'=> $dataProvider,
    ]);
}

选择两个以上选项时

当选择一个选项时，它允许我发送，但它向我显示以下错误

如果我只保存radioboxlist中的选项，它允许我毫无问题地保存，唯一的缺点是检查框列表。我希望你能指导我解决这个问题

问题出在你的

echo $count > 1?$form->field($answer, "[$index]answer")->checkboxList(ArrayHelper::map($model->questOptions, 'id_option', 'title_option'))->label('') : $form->field($answer, "[$index]answer")->radioList(ArrayHelper::map($model->questOptions, 'id_option', 'title_option'))->label('') ; ?> echo$count>1？$form->field（$answer，[$index]answer”）->复选框列表（ArrayHelp:：map（$model->questOptions，'id\u option'，'title\u option'））->标签（“”）：$form->field（$answer，[$index]answer”）->放射科医生（ArrayHelper:：map（$model->questOptions，'id\u option'，title\u option'）->标签（“”）； ?> 您需要为模型上的每个问题设置一个属性，就像这样

[['answer','answer1','answer2','answer3','answer4'], 'string']

[['answer'、'answer1'、'answer2'、'answer3'、'answer4']、'string']问题在于你的
