Installation
------------
The preferred way to install this extension is through [composer](http://getcomposer.org/download/).
Either run

```
or add
```
"yii2mod/yii2-sweet-alert": "*"
```

Usage
-------
**For render the message from session flash you can use the following code:**
1) Set the message in your action, for example:
```php
Yii::$app->session->setFlash('success', 'This is the message');
```
2) Simply add widget to your page as follows:
```php
echo Alert::widget();
```
**For render the custom message you can use the following code:**
```php
// 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:
```php
// 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:
```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);
};
```
