Codeigniter 文件上传没有获得价值

Question

我已经完成了这个以及它与我以前的项目的合作。现在，我正在做一个新项目，并试图将我的代码复制并粘贴到文件上传中。它没有任何价值。我的问题是为什么我的文件上传没有获得价值？

注意：我已经在我的助手中声明了表单，并且可能文件夹已经存在.. 我的列的名称是 img_jumbotron，我的 CI 版本是 3.3（最新）

您可以在浏览器上使用开发人员工具并检查 NETWORK（我猜是 chrome）选项卡并检查您的应用程序是否正在发送文件。

还有：

action="<?=base_url().'Administrator/addContent/'?>"

我认为您应该删除此“<?=”上的等号。
