A widget component for Yii Framework 2.0 to easily configure and initialize popup notification dialog boxes. It provides a polyfill for the native javascript alert, confirm, and prompt dialog boxes. It includes inbuilt support for rendering rich dialog boxes via [bootstrap3-dialog](http://nakupanda.github.io/bootstrap3-dialog/) which makes using Bootstrap's modal more monkey-friendly. The key features provided by the library are:
- Control how you want to render JAVASCRIPT dialogs. Inbuilt quick support for following dialog types:
- ALERT dialog
- CONFIRM dialog
- PROMPT dialog
- CUSTOM dialog
- Includes a jQuery plugin `krajeeDialog` (created by Krajee), that allows one to configure the bootstrap3-dialog library easily, or use the native JS alerting component, OR also configure any third party JS Notification Library to be used.
- Ability to render pretty dialogs by overriding and enhancing confirmation dialog for links that use yii's `data-confirm` methods.
- Advanced configuration via `kartik\dialog\Dialog` widget. This widget allows one to globally setup the native JS alert OR bootstrap3-dialog settings.

## Installation
The preferred way to install this extension is through [composer](http://getcomposer.org/download/).
### Pre-requisites
> Note: Check the [composer.json](https://github.com/kartik-v/yii2-dropdown-x/blob/master/composer.json) for this extension's requirements and dependencies.
You must set the `minimum-stability` to `dev` in the **composer.json** file in your application root folder before installation of this extension OR
if your `minimum-stability` is set to any other value other than `dev`, then set the following in the require section of your composer.json file
```
kartik-v/yii2-dialog: "@dev"
```
Read this [web tip /wiki](http://webtips.krajee.com/setting-composer-minimum-stability-application/) on setting the `minimum-stability` settings for your application's composer.json.
### Release Changes
Refer the [CHANGE LOG](https://github.com/kartik-v/yii2-dialog/blob/master/CHANGE.md) for details of various releases.
### Install
Either run
```
$ php composer.phar require kartik-v/yii2-dialog "@dev"
```
or add
```
"kartik-v/yii2-dialog": "@dev"
```
to the ```require``` section of your `composer.json` file.
## Documentation and Demo
View the [documentation and demos](http://demos.krajee.com/dialog) at Krajee Yii 2 Demos for details on using the extension.
## Usage
### Basic Usage
In your view you can load the asset bundle and render the javascript to load the bootstrap 3 modal dialog.
```php
// view.php
use kartik\dialog\DialogAsset;
DialogAsset::register($this);
$this->registerJs("\$('#your-btn-id').on('click', function(){BootstrapDialog.alert('I want banana!');});");
```
### Advanced Usage (Widget)
In your view OR view layout file, you can render the widget like this. This will not display any content directly - but will render all the javascript and css needed for initializing the BootstrapDialog as per your customized settings.
```php
use kartik\dialog\Dialog;
// Example 1
echo Dialog::widget([
'libName' => 'krajeeDialog',
'options' => [], // default options
]);
// Example 2
echo Dialog::widget([
'libName' => 'krajeeDialogCust',
'options' => ['draggable' => true, 'closable' => true], // custom options
]);
```
Then in your view, you can write your own javascript to render your alert, confirm, and prompt boxes (or a custom dialog box). For example on click of HTML buttons `btn-1` and `btn-2`, the dialogs can be popped up as shown below:
```js
// NOTE: This is a javascript code and must be run in Yii via 'registerJs'
// or via a JS File in an AssetBundle
// use krajeeDialog object instance initialized by the widget
$('#btn-1').on('click', function() {
krajeeDialog.alert('An alert');
// or show a confirm
krajeeDialog.confirm('Are you sure', function(out){
if(out) {
alert('Yes'); // or do something on confirmation
}
});
});
// use krajeeDialogCust object instance
$('#btn-2').on('click', function() {
krajeeDialogCust.alert('An alert');
// or show a prompt
krajeeDialogCust.prompt({label:'Provide reason', placeholder:'Upto 30 characters...'}, function(out){
if (out) {
alert('Yes'); // or do something based on the value of out
}
});
});
```
### Overriding Yii's Confirmation Dialog
Yii renders the native confirmation dialog on links that are rendered by setting `data-confirm` property on links. This widget
enhances and beautifies the native confirmation dialog using Krajee Dialog. This behavior can be controlled via the `overrideYiiConfirm`
property which defaults to `true`. This can be useful in rendering links and action buttons like the GridView ActionColumn
delete button.
```php
// the rendered link will automatically show a Krajee Dialog Confirmation dialog
use kartik\dialog\Dialog;
echo Dialog::widget(['overrideYiiConfirm' => true]);
echo Html::a(
'Delete',
['/item/delete', 'id' => $model->id],
[
'data-confirm' => 'Are you sure to delete this item?'
'data-method' => 'post'
]
);
```
