I'm trying to make a simple Sencha Touch App that submits a form with attached images, and stores the data in a remote MySQL database via PHP.
我正在尝试制作一个简单的Sencha Touch应用程序，它提交带有附加图像的表单，并通过PHP将数据存储在远程MySQL数据库中。
The user-inserted images are stored in a data store.
用户插入的图像存储在数据存储中。
When the user clicks the submit button, I would like all the data in the store to be encoded into a JSON string which I can easily send to my database.
当用户单击提交按钮时，我希望将商店中的所有数据编码为JSON字符串，我可以轻松地将其发送到我的数据库。
Is there any way to do this in Sencha Touch?
在Sencha Touch有什么办法吗？

You can encode image to Base64 string and when attached to your form you can store base64 string value in a hidden field in your form.
您可以将图像编码为Base64字符串，当附加到表单时，您可以将base64字符串值存储在表单的隐藏字段中。
When user clicks submit button you retrieve values in your form using activePanel.getValues(false).This gives you JSON presentation of components you used in your form and their values.
当用户单击“提交”按钮时，您将使用activePanel.getValues（false）检索表单中的值。这将为您提供表单中使用的组件及其值的JSON表示。
