简介摘要
它告诉您，$upload\u data['file\u name']
不存在
我认为这是因为你没有上传任何东西，当你上传的时候——它存在，一切都很好
所以，你可以换掉
<img alt="Your uploaded image" src="<?=base_url(). 'assets/img/' . $upload_data['file_name'];;?>">
“>
用于：
">
在尝试应用之前检查是否已设置。发现问题，应在配置文件控制器中解决：）
谢谢但是现在我发现了这个错误，遇到了一个PHP错误严重性：注意消息：未定义的偏移量：0文件名：controllers/Profile.PHP行号：18 Backtrace:File:/Applications/MAMP/htdocs/ASL/application/controllers/Profile.PHP行：18函数：_error\u handler File:/Applications/MAMP/htdocs/ASL/index.PHP行：315函数：需要你做一次什么？
