Split ActiveForm fields into different tabs with Tabs widget

问题

I'm creating a form view and I want to organize the form fields with tabs structure, using the official Tabs widget.

Is it possible init the Tabs widget with the id (or class) of the div elements that contains the active form fields?

One example of how you can manage it is doing like this:

First, divide your contact-form into one view-file for each tab.
Place the ActiveForm::begin() and ActiveForm::end() around the Tabs::widget()
Render the contact-form pages into content, with parameters $model and $form

Example code:

views/site/contact.php

<?php

/* @var $this yii\web\View */
$this->title = 'Contact';

use yii\bootstrap\Tabs;
use yii\bootstrap\ActiveForm;
?>


<?php $form = ActiveForm::begin(['id' => 'contact-form']); ?>
<?= Tabs::widget([
        'items' => [
            [
                'label' => 'One',
                'content' => $this->render('contact_form1', ['model' => $model, 'form' => $form]),
                'active' => true
            ],
            [
                'label' => 'Two',
                'content' => $this->render('contact_form2', ['model' => $model, 'form' => $form]),
            ],
        ]]);
 ?>
    <?php ActiveForm::end(); ?>

views/site/contact_form1.php

<?= $form->field($model, 'name') ?>
<?= $form->field($model, 'email') ?>
<?= $form->field($model, 'subject') ?>

views/site/contact_form2.php

<?php
use yii\helpers\Html;
use yii\captcha\Captcha;
?>

<?= $form->field($model, 'body')->textArea(['rows' => 6]) ?>
<?= $form->field($model, 'verifyCode')->widget(Captcha::className(), [
    'template' => '<div class="row"><div class="col-lg-3">{image}</div><div    class="col-lg-6">{input}</div></div>',
]) ?>
<div class="form-group">
<?= Html::submitButton('Submit', ['class' => 'btn btn-primary', 'name' => 'contact-button']) ?>
</div>

Hope this helps!

Just add at the top of your contact.php global $form; and all works fine.

I have another solution:

When we call $form->field($model, 'name')->textInput(), it will return the model of class yii\widgets\ActiveField, so just continue calling a method of this class as $form->field($model, 'name')->textInput()->render(). It will return a string then you can use it for the tab's content. I have an example code in my application for translating multi languages as the following code:

<?php
$items = [];
foreach ($translateModels as $translateModel) {
    $tabContent = $form->field($translateModel, "[{$translateModel->code}]name")->textInput()->render();
    $items[] = [
        'label' => $translateModel->language->name,
        'content' => $tabContent,
    ];
}
?>
<?= Tabs::widget([
    'options' => [
        'class' => 'nav-tabs',
        'style' => 'margin-bottom: 15px',
    ],
    'items' => $items,
]) ?>

Maybe it's help.
