您收到未定義變量錯誤,因為您沒有將變量$form從主視圖傳遞到_answers.php. 你可以這樣傳遞:
<?php $form = ActiveForm::begin([
'enableClientValidation' => false,
'enableAjaxValidation' => true,]) ?>
<?= ListView::widget([
'layout' => '<div class="pull-left">{items}</div>',
'dataProvider' => $dataProvider,
'itemView' => function ($model, $key, $index, $widget) use ($form) {
return $this->render('_answers',[
'form' => $form,
'model' => $model,
'index' => $index,
]);
},
]); ?><div class="form-group">
<?php echo Html::submitButton('<span class="fa fa-plus"></span>'.' '.Yii::t('backend', 'Send') , ['class' => 'btn btn-primary']) ?>
至于如何發送帶有問題 id 的多個答案,您可以使用vvpanchev 的答案中提到的方式或添加帶有問題 id 的隱藏字段。帶有隱藏字段的視圖_answers.php:
<td width="5%" class="vcenter" rowspan="3">
<span class="panel-title-address"><label class="control-label">Nr: <?php echo ($index+1); ?></label></span>
</td>
<td width="95%" class="vcenter">
<div class="form-group field-qquestion-0-title required">
<label class="control-label" for="qquestion-type_id"><?= Yii::t('backend', 'Question'.' : ')?></label>
</div>
<div class="form-group field-qquestion-0-title required">
<label class="control-label" for="qquestion-type_id"><?= $model->question ?></label>
</div>
<div class="col-md-4">
<?php
//set the question's id to answer model if you haven't done that already
$answer->question_id = $model->id;
//output the hidden input with question id
echo \yii\helpers\Html::activeHiddenInput($answer, "[$index]question_id");
?>
<?php echo $form->field($answer, "[$index]answer")->textInput(['maxlength' => true]) ?>
</div>
</td>
如果您使用隱藏字段方法,那么在控制器中您可以使用\yii\base\Model::loadMultiple()方法將數據加載到答案模型中。您還可以用于\yii\base\Model::validateMultiple()驗證。我假設答案模型類的名稱是Answer.
$count = count(\Yii::$app->request->post('Answer', []));
$answers = [];
for ($i = 0; $i < $count; $i++) {
$answers[] = new Answer();
}
if (
\yii\base\Model::loadMultiple($answers, \Yii::$app->request->post())
&& \yii\base\Model::validateMultiple($answers)
) {
// ... save your answers and/or do other things needed
}

像這樣更改您的答案輸入,您將獲得每個問題的答案輸入:
<?php echo $form->field($answer, '['.$model->id.']answer')->textInput(['maxlength' => true]) ?>
當您提交表格時,它將連同所有問題的答案一起提交。所以你可以像這樣檢查并保存$_POST:
if(isset($_POST['Answer']) and !empty($_POST['Answer'])){
foreach($_POST['Answer'] as $question_id => $answer){
//save your answer to your question
}
}
你也必須像這樣改變你的ajaxvalidation foreach
