如何使用textInput保存mysql中自动生成的多个Yii2数组值

Question

你好，我希望使用MySQL将多个表单字段值保存到Yii2数据库表中，而无需编写任何自定义查询代码。我的表结构是id主键auto_incremented的位置。我的数组结构如下所示

表单字段是

   <tr>
              <td>1</td>
              <td><?= $form->field($coordinatemodel,'lat_degree[]')->textInput(['placeholder'=>'Degree','data-validation'=>'required number','data-validation-error-msg'=>'*Required','required'=>'required'])->label('Degree')->label(false)?></td>
              <td><?= $form->field($coordinatemodel,'lat_min[]')->textInput(['placeholder'=>'Minute','data-validation'=>'required number','data-validation-error-msg'=>'*Required','required'=>'required'])->label('Minute')->label(false)?></td>
              <td><?= $form->field($coordinatemodel,'lat_second[]')->textInput(['placeholder'=>'Second','data-validation'=>'required number','data-validation-error-msg'=>'*Required','required'=>'required'])->label('Second')->label(false)?></td>
              <td><?= $form->field($coordinatemodel,'long_degree[]')->textInput(['class'=>'form-control input-sm','placeholder'=>'Degree','data-validation'=>'required number','data-validation-error-msg'=>'*Required','required'=>'required'])->label('Degree')->label(false)?></td>
              <td><?= $form->field($coordinatemodel,'long_min[]')->textInput(['class'=>'form-control input-sm','placeholder'=>'Minute','data-validation'=>'required number','data-validation-error-msg'=>'*Required','required'=>'required'])->label('Minute')->label(false)?></td>
              <td><?= $form->field($coordinatemodel,'long_second[]')->textInput(['class'=>'form-control input-sm','placeholder'=>'Second','data-validation'=>'required number','data-validation-error-msg'=>'*Required','required'=>'required'])->label('Second')->label(false)?></td>
            </tr> 
            <tr>
              <td>2</td>
              <td><?= $form->field($coordinatemodel,'lat_degree[]')->textInput(['placeholder'=>'Degree','data-validation'=>'required number','data-validation-error-msg'=>'*Required','required'=>'required'])->label('Degree')->label(false)?></td>
              <td><?= $form->field($coordinatemodel,'lat_min[]')->textInput(['placeholder'=>'Minute','data-validation'=>'required number','data-validation-error-msg'=>'*Required','required'=>'required'])->label('Minute')->label(false)?></td>
              <td><?= $form->field($coordinatemodel,'lat_second[]')->textInput(['placeholder'=>'Second','data-validation'=>'required number','data-validation-error-msg'=>'*Required','required'=>'required'])->label('Second')->label(false)?></td>
              <td><?= $form->field($coordinatemodel,'long_degree[]')->textInput(['class'=>'form-control input-sm','placeholder'=>'Degree','data-validation'=>'required number','data-validation-error-msg'=>'*Required','required'=>'required'])->label('Degree')->label(false)?></td>
              <td><?= $form->field($coordinatemodel,'long_min[]')->textInput(['class'=>'form-control input-sm','placeholder'=>'Minute','data-validation'=>'required number','data-validation-error-msg'=>'*Required','required'=>'required'])->label('Minute')->label(false)?></td>
              <td><?= $form->field($coordinatemodel,'long_second[]')->textInput(['class'=>'form-control input-sm','placeholder'=>'Second','data-validation'=>'required number','data-validation-error-msg'=>'*Required','required'=>'required'])->label('Second')->label(false)?></td>
            </tr> 
            <tr>
              <td>3</td>
              <td><?= $form->field($coordinatemodel,'lat_degree[]')->textInput(['placeholder'=>'Degree','data-validation'=>'required number','data-validation-error-msg'=>'*Required','required'=>'required'])->label('Degree')->label(false)?></td>
              <td><?= $form->field($coordinatemodel,'lat_min[]')->textInput(['placeholder'=>'Minute','data-validation'=>'required number','data-validation-error-msg'=>'*Required','required'=>'required'])->label('Minute')->label(false)?></td>
              <td><?= $form->field($coordinatemodel,'lat_second[]')->textInput(['placeholder'=>'Second','data-validation'=>'required number','data-validation-error-msg'=>'*Required','required'=>'required'])->label('Second')->label(false)?></td>
              <td><?= $form->field($coordinatemodel,'long_degree[]')->textInput(['class'=>'form-control input-sm','placeholder'=>'Degree','data-validation'=>'required number','data-validation-error-msg'=>'*Required','required'=>'required'])->label('Degree')->label(false)?></td>
              <td><?= $form->field($coordinatemodel,'long_min[]')->textInput(['class'=>'form-control input-sm','placeholder'=>'Minute','data-validation'=>'required number','data-validation-error-msg'=>'*Required','required'=>'required'])->label('Minute')->label(false)?></td>
              <td><?= $form->field($coordinatemodel,'long_second[]')->textInput(['class'=>'form-control input-sm','placeholder'=>'Second','data-validation'=>'required number','data-validation-error-msg'=>'*Required','required'=>'required'])->label('Second')->label(false)?></td>
            </tr> 

id lat_degree lat_min lat_second long_degree long_min long_second

Answer 1

表格输入的文档对此有一个解释。您可以修改您的actionCreate以包括此内容。

首先，需要先填充创建一个模型数组才能填充：

$count = count(Yii::$app->request->post('CoordinateDetails', []));
$coordinateDetails = [new CoordinateDetail()];
for ($i = 1; $i < $count; $i++) {
    $coordinateDetails[] = new CoordinateDetail();
}

然后，您可以使用loadMultiple和validateMultiple来填充和验证模型。但是，为了保存模型，您必须遍历模型：

if (CoordinateDetail::loadMultiple($coordinateDetails, Yii::$app->request->post()) 
    && CoordinateDetail::validateMultiple($coordinateDetails)) {
    foreach ($coordinateDetails as $coordinateDetail) {
        //do any other thing here e.g. setting foreign keys
        $coordinateDetail->save(false);
    }
    return $this->redirect('index');
}
else {
    // do something for the error
}

Answer 2

我认为您应该使用batchInsert方法：

        \Yii::$app->db->createCommand()->batchInsert('yourtable', ['lat_degree','lat_min','lat_second',...],$CoordinatesDetail )
        ->bindValue(':id', 1)
        ->execute();

Answer 3

当我在我的项目中有这样的场景时，我使用yii2 2-动态形式扩展，它声明：

它是yii2框架的小部件，可以以嵌套的方式克隆表单元素，从而保持可访问性。

检查它是演示这里。
