yii2-dialog

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 a customized plugin by Krajee based on and enhanced from bootstrap3-dialog. This plugin makes using Bootstrap's modal more monkey-friendly. The Krajee enhancements also includes enhanced support for Bootstrap 5.x, 4.x and 3.x. 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.

Documentation and Demo

View the documentation and demos 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.

// 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.

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:

// 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.

// 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'
    ]
);
