Usage

First of all you need write form config (you can store it in model class)

<?php

namespace app\models;

use metalguardian\formBuilder\ActiveFormBuilder;

/**
 */
class Example extends \yii\db\ActiveRecord
{
    .....
    /**
     * @return array
     */
    public function getFormConfig()
    {
        return [
            'label' => [
                'type' => ActiveFormBuilder::INPUT_TEXT,
            ],
            'content' => [
                'type' => ActiveFormBuilder::INPUT_TEXTAREA,
                'hint' => 'hint about field',
            ],
            'type' => [
                'type' => ActiveFormBuilder::INPUT_DROPDOWN_LIST,
                'items' => [1 => 'One', 2 => 'Two'],
                'options' => [
                    'prompt' => 'select',
                ],
            ],
            'published' => [
                'type' => ActiveFormBuilder::INPUT_CHECKBOX,
            ],
            'redactor' => [
                'type' => ActiveFormBuilder::INPUT_WIDGET,
                'widgetClass' => \vova07\imperavi\Widget::className(),
            ],
            'raw_data' => [ // need to define attribute `raw_data` in model 
                'type' => ActiveFormBuilder::INPUT_RAW,
                'value' => 'raw html data',
            ],
        ];
    }
}

Now in form view you can write something like this:

.....
<?php $form = \metalguardian\formBuilder\ActiveFormBuilder::begin(); ?>

<?= $form->renderForm($model, $model->getFormConfig()) ?>

<div class="form-group">
    <?= Html::submitButton(Yii::t('app', 'Save'), ['class' => 'btn btn-success']) ?>
</div>

<?php \metalguardian\formBuilder\ActiveFormBuilder::end(); ?>
.....

Advanced Usage

You can define configuration of different elements in model

<?php

namespace app\helpers;

use metalguardian\formBuilder\ActiveFormBuilder;

/**
 */
class Helper
{
    .....
    /**
     * @return array
     */
    public static function getLabelConfig()
    {
        return [
            'type' => ActiveFormBuilder::INPUT_TEXT,
        ];
    }

    /**
     * @return array
     */
    public static function getContentConfig()
    {
        return [
            'type' => ActiveFormBuilder::INPUT_TEXTAREA,
        ];
    }
}

Now you can use different models in one form

.....
<?php $form = \metalguardian\formBuilder\ActiveFormBuilder::begin(); ?>

<?= $form->renderField($model1, 'label', \app\helpers\Helper::getLabelConfig()); ?>
<?= $form->renderField($model1, 'content', \app\helpers\Helper::getContentConfig()); ?>

<?= $form->renderField($model2, 'label', \app\helpers\Helper::getLabelConfig()); ?>
<?= $form->renderField($model2, 'content', \app\helpers\Helper::getContentConfig()); ?>

<div class="form-group">
    <?= Html::submitButton(Yii::t('app', 'Save'), ['class' => 'btn btn-success']) ?>
</div>

<?php \metalguardian\formBuilder\ActiveFormBuilder::end(); ?>
.....
