我正在尝试为我的视图添加materialize css,这是我的视图/ layouts / index.php：

    </div>

    <!--Import jQuery before materialize.js-->
    <script type="text/javascript"
            src="https://code.jquery.com/jquery-2.1.1.min.js">
    </script>
    <script type="text/javascript"
            src="<?php echo $this->theme->baseUrl ?>/frontend/web/js/materialize.min.js">
    </script>
    <script type="text/javascript">
        $(function () {
            $(".button-collapse").sideNav();
        });
    </script>
    <?php $this->endBody(); ?>
    </body>
    </html>
<?php $this->endPage(); ?>

另外,在配置中：

'components' => [
        'assetManager' => [
            'bundles' => [
                'yiiwebJqueryAsset' => [
                    'js'=>[]
                ],'yiibootstrapBootstrapPluginAsset' => [
                    'js'=>[]
                ],'yiibootstrapBootstrapAsset' => [
                    'css' => [],

但它返回：

PHP Notice – yiibaseErrorException

Trying to get property of non-object

这条线是高位的：

href =“theme-> baseUrl;？> /frontend/web/css/materialize.min.css”

我还是不能用这个主题：D

来自：http://www.bsourcecode.com/yiiframework2/install-new-theme-in-yiiframework-2/#sample-theme-layout

AppAssets：

<?php
/**
 * @link http://www.yiiframework.com/
 * @copyright Copyright (c) 2008 Yii Software LLC
 * @license http://www.yiiframework.com/license/
 */

namespace frontendassets;

use yiiwebAssetBundle;

/**
 * @author Qiang Xue <qiang.xue@gmail.com>
 * @since 2.0
 */
class AppAsset extends AssetBundle
{
    public $basePath = '@webroot';
    public $baseUrl = '@web';
    public $css = [
        '/frontend/web/css/materialize.css','/frontend/web/css/materialize.min.css',];
    public $js = [
        '/frontend/web/js/materialize.js','/frontend/web/js/materialize.min.js',];
    public $depends = [
        # 'yiiwebYiiAsset',# 'yiibootstrapBootstrapAsset',];


}

解决方法

http://www.yiiframework.com/doc-2.0/yii-web-view.html#registerCssFile()-detail

是Yii方式注册CSS文件,但建议通过assestBundles完成.我现在使用它们而且更喜欢它们.

http://www.yiiframework.com/doc-2.0/yii-web-assetbundle.html

在$css数组中,只列出您要使用的文件.
http://www.yiiframework.com/doc-2.0/guide-structure-assets.html

<?php

namespace appassets;

use yiiwebAssetBundle;

class AppAsset extends AssetBundle
{
public $basePath = '@webroot';
public $baseUrl = '@web';
public $css = [
    'css/path_to_materialize.css',];
public $js = [
];
public $depends = [
    'yiiwebYiiAsset','yiibootstrapBootstrapAsset',];

}
