Question

我尝试按照tutorial

扩展 BaseHtml 类

但是找不到BaseHtml扩展类

namespace common\components;

class Html extends \yii\helpers\BaseHtml {
}

这是错误：

Class 'yii\helpers\BaseHtml' not found

我哪里错了？

更新

我尝试复制位于Helpers中的Html.php文件并且仍然是相同的

<?php
/**
 * @link http://www.yiiframework.com/
 * @copyright Copyright (c) 2008 Yii Software LLC
 * @license http://www.yiiframework.com/license/
 */
namespace yii\helpers;
/**
 * Html provides a set of static methods for generating commonly used HTML tags.
 *
 * Nearly all of the methods in this class allow setting additional html attributes for the html
 * tags they generate. You can specify, for example, `class`, `style` or `id` for an html element
 * using the `$options` parameter. See the documentation of the [[tag()]] method for more details.
 *
 * For more details and usage information on Html, see the [guide article on html helpers](guide:helper-html).

class Html extends BaseHtml
{
}

现在我还有另外一个问题。它找不到原始类的BaseHtml

vendor/yiisoft/yii2/helpers/Html.php

找到解决方案

我重构了覆盖文件，phpStorm改变了我在vendor / yiisoft / yii2 / classe.php中的BaseHtml路径

Answer 1

BaseHtml.php应位于/ vendor / yiisoft / yii2 / helpers /文件夹下。如果不存在，您需要更新供应商或尝试将文件BaseHtml.php复制到yii2 / helper yii2 repo：https://github.com/yiisoft/yii2/blob/b7b9c8ba40d65ec7c745ee639a8a6eb96e7aea75/framework/helpers/BaseHtml.php 希望它有所帮助。
