4    <aui:input name="user_id" label="User ID" disabled="true" value='${User_id }'/>
5    <aui:input name="file" inlineLabel="left" type="file" style="width: auto;"></aui:input>
6</aui:form>

File Upload Action file

2
3public void processAction(
4          ActionRequest actionRequest, ActionResponse actionResponse)
5       throws IOException, PortletException {
6
7       UploadPortletRequest uploadRequest = PortalUtil.getUploadPortletRequest(actionRequest);
8       String sourceFileName =uploadRequest.getFullFileName("file"); //getFileName("file");
9
10    System.out.println("sourceFile Full Name    " + sourceFileName);    // I am getting the sourceFile Full Name proper. When I am using enctype="multipart/form-data"
11       int userId = Integer.parseInt(actionRequest.getParameter("user_id"));       // here I am getting Error
12
13    }
14}

Hi,

If you need the current user then use themeDisplay to access it in your processAction method.

If you check EditFileEntryAction.java you will see how to extract other parameters like:

1
2long folderId = ParamUtil.getLong(uploadPortletRequest, "folderId");
3String sourceFileName = uploadPortletRequest.getFileName("file");

Hope it helps.

Hi Vilmos,

The issue is whenever , I am trying to get the and Integer, String , Float value from form inside the Process Action by using,

1
2 int foo = Integer.parseInt(actionRequest.getParameter("foo"));
3float fee = Float.parseFloat(actionRequest.getParameter("fee"));
4String remark = actionRequest.getParameter("remarks");
5

Even I have used ParamUtil .

1
2int foo = ParamUtil.getInteger(actionRequest, "foo");

In both above case I am getting Null value , This is because I am using enctype="multipart/form-data" inside view.jsp <FORM> tag for the file Upload.
