Question

我有这样的ActiveForm。如何在此视图中允许用户选择子项数（表单项）并提交所有 子项数 相同的模型项。

<?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',

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

Answer 1

只需将模型类添加为公共字段，并将规则作为安全属性放入

Answer 2

答案是使用简单的for循环。

视图示例

<?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(); ?>

并在控制器中使用

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

Yii2。一个表单中的多个模型项
