我正在嘗試通過Id將數據插入數據庫。我有三個問題，我有這些問題的答案。問題 ID 已正確插入表中。但是這些問題的答案 Id 未正確插入。表中只插入一個問題答案。讓我解釋一下這個函數：$post['SurveyAnswer']['question_id']有三個值。如果我們的結果就是。print_r( $post['SurveyAnswer']['question_id'])Array( [0] => 833 [1] => 834 [2] => 835)現在我有了這個問題的答案。和輸出是。print_r($post['SurveyAnswer']['answer']);Array( [0] => text123 [1] => hello [2] => hello)我試圖做的是將答案保存在數據庫中，其中包含特定問題。我需要這樣的結果。 [833] => text123 [834] => hello [835] => hello這是我的職能public function actionSaveAnswer(){ $post = \Yii::$app->request->post(); // echo "<pre>";print_r($post);die(); foreach ($post['SurveyAnswer']['question_id'] as $ques) { $post['SurveyAnswer']['answer']; $surveyAnswer = new SurveyAnswer(); $surveyAnswer->question_id = $ques; } if ($surveyAnswer->save()) { $flag = true; \Yii::$app->session->setFlash('success', \Yii::t('app', 'Your answers saved successfully.')); }}

我看不出你在哪里添加答案。如果您的答案和問題ID與您指示的匹配，請嘗試以下操作：
foreach ($post['SurveyAnswer']['question_id'] as $id => $ques) {
$surveyAnswer = new SurveyAnswer();
$surveyAnswer->question_id = $ques;
$surveyAnswer->answer = $post['SurveyAnswer']['answer'][$id];
$surveyAnswer->save();
}
您應該在循環中保存答案。否則，將僅保存一行。
