Yii2。一种形式的多个模型项目

Question

我有这样的ActiveForm。如何在此视图中允许用户选择一些儿童（表单项）并提交全部儿童人数相同型号的项目。

<?php $form = ActiveForm::begin([]) ?> 
    <div class="child_card"> 

      <?=$form->field($child, 'first_name', ['inputOptions' => ['placeholder' => 'Enter Your First Name']])?> 

       <?=$form->field($child, 'middle_name', 
        ['inputOptions' => ['placeholder' => 'Enter Your Middle Name']])?> 

       <?=$form->field($child, 'last_name', ['inputOptions' => ['placeholder' => 'Enter Your Last Name']])?> 
       <br> 

       <?=$form->field($child, 'gender', [ 
        'template'  => '{label} <div class="field">{input}{error}{hint}</div>', 
        'inputOptions' => [ 
         'placeholder' => 'Gender', 
        ], 
       ])->dropDownList([ 
        'male' => 'Male', 
        'female' => 'Female', 
       ], ['class' => 'ui dropdown selection', 'prompt' => 'Gender'])->label('Select your gender')?> 

       <?=$form->field($child, 'birthdate_month', [ 
        'template'  => '{label} <div class="field">{input}{error}{hint}</div>', 
        'inputOptions' => [ 
         'placeholder' => 'Month', 
        ], 
       ])->dropDownList([ 
        'January' => 'January',

       <?=$form->field($child, 'country_of_birth', 
        ['inputOptions' => ['placeholder' => "Enter Your Child's Country of Birth"]]) 
         ->label('Your Child’s Country of Birth:')?> 

       <?=$form->field($child, 'city_of_birth', 
        ['inputOptions' => ['placeholder' => "Enter Your Child's City of Birth"]]) 
         ->label('Your Child’s City/Town of Birth:')?> 
     </div> 
     <?php ActiveForm::end(); ?> 

Answer 1

答案是使用一个简单的for循环。视图

<?php $form = ActiveForm::begin() ?> 

<?php foreach ($children as $i => $child): ?> //there are multiple persons (children) 

... 

<?=$form->field($child, "[$i]birthdate_month", [...])->dropDownList([ 
        '1' => 'January', 
        ... 
       ])?> 

... 

<?php endforeach; ?> 

... 

<?=Html::submitButton('Save', ['class' => 'ui primary button big'])?> 
... 

<?php ActiveForm::end(); ?> 

而在控制器使用的

例

Person::loadMultiple($children, Yii::$app->request->post());

模型类只需添加在公共领域投入的规则，安全属性
