Php 在assetmanager中使用自定义函数

如何在yii2 assetmanager中使用

Yii:：$app->session['somename']

class AppAsset extends AssetBundle{
public function getLang() {
  $currentLang = Yii::$app->session['lang'];
    if ($currentLang == 'fa' || $currentLang == 'ar') {
        return 'RTL';
    } else {
        return 'LTR';
    }
}
public $lang;

public $basePath = '@webroot';
public $baseUrl = '@web';
public $css = [
    'css/iconSprite.min.css',
     // how call getLang here
 ]

如何在assetmanager中访问某些函数

class AppAsset extends AssetBundle{
public function getLang() {
  $currentLang = Yii::$app->session['lang'];
    if ($currentLang == 'fa' || $currentLang == 'ar') {
        return 'RTL';
    } else {
        return 'LTR';
    }
}
public $lang;

public $basePath = '@webroot';
public $baseUrl = '@web';
public $css = [
    'css/iconSprite.min.css',
     // how call getLang here
 ]

如何在css部分调用

getLang

？

您可以这样做

.. other functions

public function init() {
    $this->setupAssets();
    parent::init();
}

protected function setupAssets() {
    $lang = $this->getLang();
    $this->css[] = "css/myfile.$lang.css";
}
