README

A wrapper around Yii2 Bootstrap Modal for using an ActiveForm via AJAX inside supporting mutiple stacked modal windows, i.e. when you open one modal window containing a form to create associated data and that form also contains a button to open another modal window, it will work too.

This work is based on loveorigami/yii2-modal-ajax. Initially I wanted to fork but later understood that the widget requires major rework to suite my needs. It solves lack of multiple stacked modal windows problem in the original Yii2 extension.

Installation

The preferred way to install this extension is through composer.

Either run

$ php composer.phar require --prefer-dist igorvolnyi/yii2-modal-ajax-multi "@dev"

or add

"igorvolnyi/yii2-modal-ajax-multi": "*"

to the require section of your composer.json file.

Usage

Controller

Extend your basic logic with ajax render and save capabilities:

public function actionCreate()
{
    $model = new Company();

    if ($model->load(Yii::$app->request->post())) {
        if ($model->save()) {             
            return $this->redirect(['view', 'id' => $model->id]);             
        }
    }

    return $this->render('create', [
        'model' => $model,
    ]);
}

to

public function actionCreate()
{
    $model = new Company();

    if ($model->load(Yii::$app->request->post())) {
        if ($model->save()) {             
            if (Yii::$app->request->isAjax) {
                // JSON response is expected in case of successful save
                Yii::$app->response->format = \yii\web\Response::FORMAT_JSON;
                return ['success' => true];
            }
            return $this->redirect(['view', 'id' => $model->id]);             
        }
    }

    if (Yii::$app->request->isAjax) {
        return $this->renderAjax('create', [
            'model' => $model,
        ]);
    } else {
        return $this->render('create', [
            'model' => $model,
        ]);
    }
}

View

use igorvolnyi\widgets\ModalAjaxMulti;

echo ModalAjaxMulti::widget([
    'id' => 'createCompany',
    'header' => 'Create Company',
    'toggleButton' => [
        'label' => 'New Company',
        'class' => 'btn btn-primary pull-right'
    ],
    'url' => Url::to(['/partner/default/create']), // Ajax view with form to load
    'ajaxSubmit' => true, // Submit the contained form as ajax, true by default
    // ... any other yii2 bootstrap modal option you need
]);

Usage in grid

Index View - Create (Single Modal Mode)

use igorvolnyi\widgets\ModalAjaxMulti;

echo ModalAjaxMulti::widget([
    'id' => 'createCompany',
    'header' => 'Create Company',
    'toggleButton' => [
        'label' => 'New Company',
        'class' => 'btn btn-primary pull-right'
    ],
    'url' => Url::to(['/partner/default/create']), // Ajax view with form to load
    'ajaxSubmit' => true, // Submit the contained form as ajax, true by default

    'options' => ['class' => 'header-primary'],
    'autoClose' => true,
    'pjaxContainer' => '#grid-company-pjax',

]);

Index View - Update (Multi Modal Mode)

Grid example with data-scenario

<a class="btn" href="/site/update?id=10" title="Edit ID-10" data-scenario="hello">Hello</a>
<a class="btn" href="/site/update?id=20" title="Edit ID-20" data-scenario="goodbye">Goodbye</a>

Modal Ajax with events

use igorvolnyi\widgets\ModalAjaxMulti;

echo ModalAjax::widget([
    'id' => 'updateCompany',
    'selector' => 'a.btn' // all buttons in grid view with href attribute
    'ajaxSubmit' => true, // Submit the contained form as ajax, true by default

    'options' => ['class' => 'header-primary'],
    'pjaxContainer' => '#grid-company-pjax',
    'events'=>[
        ModalAjaxMulti::EVENT_MODAL_SHOW => new \yii\web\JsExpression("
            function(event, data, status, xhr, selector) {
                selector.addClass('warning');
            }
       "),
        ModalAjaxMulti::EVENT_MODAL_SUBMIT => new \yii\web\JsExpression("
            function(event, data, status, xhr, selector) {
                if(status){
                    if(selector.data('scenario') == 'hello'){
                        alert('hello');
                    } else {
                        alert('goodbye');
                    }
                    $(this).modal('toggle');
                }
            }
        ")
    ]

]);
