Yii2水平形式

Question

我想要做的是从bootstrap垂直更改为水平形式,这是我尝试过的:

<?php $form = ActiveForm::begin([
    'layout' => 'horizontal',
    'action' => ['index'],
    'method' => 'get',
    'fieldConfig' => [
        'horizontalCssClasses' => [
            'label' => 'col-sm-2',
            'offset' => 'col-sm-offset-2',
            'wrapper' => 'col-sm-4',
        ],
    ],
]); ?>
    <div class="row">
        <div class="col-md-6">
            <?= $form->field($model, 'firstname') ?>
            <?= $form->field($model, 'lastname') ?>
       </div>
        <div class="col-md-6">
            <?= $form->field($model, 'email') ?>
            <?= $form->field($model, 'bla') ?>
       </div>
    </div>
<?php ActiveForm::end() ?>

但它给了我一个错误设置未知属性:yii\widgets\ActiveForm :: layout请帮助!!!

Answer 1

对于layout工作选项ActiveForm必须是实例yii\bootstrap\ActiveForm而不是yii\widgets\ActiveForm.

改变你的use陈述.
