Usage

For render the message from session flash you can use the following code:

1) Set the message in your action, for example:

Yii::$app->session->setFlash('success', 'This is the message');

2) Simply add widget to your page as follows:

echo Alert::widget();

For render the custom message you can use the following code:

// A replacement for the "prompt" function

echo \yii2mod\alert\Alert::widget([
    'useSessionFlash' => false,
    'options' => [
        'timer' => null,
        'type' => \yii2mod\alert\Alert::TYPE_INPUT,
        'title' => 'An input!',
        'text' => "Write something interesting",
        'confirmButtonText' => "Yes, delete it!",
        'closeOnConfirm' => false,
        'showCancelButton' => true,
        'animation' => "slide-from-top",
        'inputPlaceholder' => "Write something"
    ],
    'callback' => new \yii\web\JsExpression(' function(inputValue) { 
                if (inputValue === false) return false;      
                if (inputValue === "") { 
                    swal.showInputError("You need to write something!");     
                    return false;   
                }      
                swal("Nice!", "You wrote: " + inputValue, "success"); 
    }')
]);

You can also change the theme of SweetAlert!

To change the theme, you can configure the assetManager array in your application configuration:

// twitter theme

'assetManager' => [
    'bundles' => [
        'yii2mod\alert\AlertAsset' => [
            'css' => [
                'dist/sweetalert.css',
                'themes/twitter/twitter.css',
            ]
        ],
    ],
]

You can override the Yii2 default data-confirm popup by the following code:

The basics are to include the asset, then add this JS:

/**
 * Override the default yii confirm dialog. This function is
 * called by yii when a confirmation is requested.
 *
 * @param message the message to display
 * @param okCallback triggered when confirmation is true
 * @param cancelCallback callback triggered when cancelled
 */
yii.confirm = function (message, okCallback, cancelCallback) {
    swal({
        title: message,
        type: 'warning',
        showCancelButton: true,
        closeOnConfirm: true,
        allowOutsideClick: true
    }, okCallback);
};
