Php OpenCart将表单添加到管理页面

opencart 1.5.6

尝试在管理员端添加一个页面，将图像上传到新文件夹（用于站点的其他部分）

我有一个问题，在图像是从表单上传页面重定向到管理员主页。我试图通过在表单响应中重新呈现当前页面来修复此问题，但现在我只加载了一个没有更新的页面版本，并且函数似乎没有运行：

模板文件：（hello.tpl）

在控制器中，您应该构建OpenCart用于表单发布的所有标准方法，例如：

公共函数插入（）

公共函数更新（）

公共函数getForm（）

等等

看看
admin/controller/catalog/attribute.php

您将看到一个名为
insert（）
的公共方法，它通过
$request
对象捕获您的post数据，即：
if（$this->request->server['request\u method']=='post'）&&$this->validateForm（）{
只有在满足条件的情况下，才会执行其中的所有代码，然后该方法将您转发到
$this->getForm（）
，您的页面就是在这里呈现的

我不确定你从哪里得到了你开始使用的示例代码，但它不正确，或者至少不符合正常的OpenCart标准

使用不同文件中的现有代码来创建新模块。
更新：好。因此，经过一些小改动后，我似乎已接近解决方案……我相信问题出现在提交表单时，我不完全确定另一端的函数是否收到表单的任何信息（学习）写一个OpenCart模块/扩展，请先学习PHP。现在是2013年，你的代码看起来像是1995年的（+5年，因为你使用了来自现有控制器的代码）…这并不是要冒犯你，而是要提醒你-OpenCart是按它的方式编写的-但是代码非常可读、干净和漂亮-你制作的代码让我想知道今天的人们从哪里学习PHP（可能的答案：从1995年之前编写的源代码/文章/书籍）。
