Installation

The preferred way to install this extension is through composer.

Note: Check the composer.json for this extension's requirements and dependencies. Read this web tip /wiki on setting the minimum-stability settings for your application's composer.json.

Either run

$ php composer.phar require kartik-v/yii2-icons "@dev"

or add

"kartik-v/yii2-icons": "@dev"

to the require section of your composer.json file.

Usage

Global Setup

In case you wish to setup one Icon framework globally, set the parameter icon-framework in the params array of your Yii Configuration File.

'params' => [
  'icon-framework' => \kartik\icons\Icon::FAS,  // Font Awesome Icon framework
]

To initialize the globally setup framework in your view, call this code in your view or view layout file.

use kartik\icons\Icon;
Icon::map($this);  

Per View Setup

You can also call each icon-framework individually in your view or view layout like below. Map any icon framework within each view as in the example below.

use kartik\icons\Icon;
Icon::map($this, Icon::EL); // Maps the Elusive icon font framework

Displaying Icons

After mapping your icon framework with one of the options above, you can display icons using Icon::show method. Icons can be displayed using one of the options below:

use kartik\icons\Icon;

// Option 1: Uses the `icon-framework` setup in Yii config params. 
echo Icon::show('user'); 

// Option 2: Specific Icon Call in a view. Additional options can also be passed to style the icon.
echo Icon::show('user', ['class'=>'fa-2x', 'framework' => Icon::FAS]); 

NOTE: The kartik\icons\Icon::show method outputs a HTML formatted text. So in order to display icons in Yii-2 components like Navbar or Nav, you must set encodeLabels to false.

$items = [
    ['label' => Icon::show('home') . 'Home', 'url' => ['/site/index']],
];

// Your other code

/* Note you must encodeLabels to false to display icons in labels */
echo \kartik\nav\NavX::widget([
    'items' => $items,
    'encodeLabels' => false
]);

// Your other code

Displaying Stacked Icons

You can also display stacked icons for frameworks like Font Awesome, where this is supported. For example:

use kartik\icons\Icon;
// fa-twitter on fa-square
 Icon::showStack('twitter', 'square', ['class'=>'fa-lg'], ['framework' => Icon::FAB], ['framework' => Icon::FAR])

// fa-flag on fa-circle
 Icon::showStack('flag', 'circle', ['class'=>'fa-lg'], ['class'=>'fa-inverse']);

Add Custom Icons

You can add custom icon sets to the list of available frameworks.

use kartik\icons\Icon;
// add framework
Icon::addFramework('custom', [
    'class' => '\common\icons\CustomIconAsset',
    'prefix' => 'custom-icon',
]);

// map to view file
Icon::map($this, 'custom');

// show the icon
echo Icon::show('menu',['framework' => 'custom']);

namespace common\icons;
class CustomIconAsset extends \yii\web\AssetBundle
{
    public $sourcePath = '@common/icons/assets/custom';
    public $depends = array(
        'yii\web\YiiAsset',
        'yii\bootstrap4\BootstrapAsset'
    );
    public $css=[
        'css/animation.css',
        'css/custom-codes.css',
        'css/custom-embedded.css',
        'css/custom-ie7.css',
        'css/custom-ie7-codes.css',
        'css/custom.css',
    ];
}
