嗨，我是 zend 框架的新手，我创建了一个应用程序，它允许用户编辑图像并在图像中放置一些文本，所以我决定通过实现 personalmug 应用程序来学习 zend 框架，
我已将应用程序上传到托管服务器子域，但由于某种原因，我的应用程序与在 localhost 上的工作方式不同。在本地主机上它工作正常，但在托管服务器上我不知道什么是磨损，但是在 ajax 成功后有一些关于在本地主机上重定向的问题。
下面给出问题。
问题 1。
- 当我打开主页并单击自定义按钮时，它将显示一个包含表单的模型，具有四个输入字段，当我输入 4 行并单击预览按钮时，它将调用控制器personalmug 并且动作是预览，预览操作将从 public/img/ 文件夹中的现有图像创建图像，现在它不会将图像创建到文件夹 public/img/image_uri 并且响应是空白页，并且在萤火虫中的 html 消息是“重新加载页面以获取源”。当我重新加载页面时，图像不存在并且图像不在托管服务器上的 public/img/image_uri 文件夹中，并且未创建会话，我认为预览操作存在一些问题。但不知道我在哪里磨损，我试图从 4 天开始用谷歌搜索，但没有成功。
同样的事情也在本地主机上工作。
问题 2
- 我想在单击 preview.phtml 页面上的保存按钮后重定向页面，现在我在控制器中有一个保存操作，它将数据保存在 localhost mysql 数据库中，它正在重定向但仅在 firbug 中，实际页面是不重定向，我尝试在 ajax 成功中使用警报，但没有使用它不显示消息。
请提前帮助和感谢。我将不胜感激我的代码更正。和一些代码示例。再次感谢。
