Hi All,
I have a problem while i try to send the parameter within the same form of image <aui:input label="Price" name="phonePrice" type="text" > and <input name="filesToUpload" id="filesToUpload" type="file" multiple />. It is not sending phonePrice parameter if i put enctype="multipart/form-data" from aui:form tab. If i remove enctype="multipart/form-data" then the file(filesToUpload) not sending. Please advise.

My JSP page.

Can you post here your controller method where you are retrieving those params?

Hi Juan, Sushil,
Thanks for suggest. Please see following code. I can get the file name and i can successfully upload the file with following code when i put enctype="multipart/form-data" in form tab however i can't get phonePrice parameter. If i remove enctype="multipart/form-data" from form tab then i can get phonePrice parameter but can't get file parameter.

MyController.java
public void uploadCase(ActionRequest actionRequest,
ActionResponse actionResponse) throws PortletException,
IOException {

long folderNameID=102;
long folderId=0;

String phonePrice=ParamUtil.getString(actionRequest, "phonePrice");
logger.info("phonePrice ::: "+phonePrice);

try {
folderId = addFileEntry(actionRequest, folderNameID);
} catch (PortalException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}catch ( SystemException e) {
e.printStackTrace();
}
logger.info("folderId Before put to request : "+folderId);
actionResponse.setRenderParameter("folderId", String.valueOf(folderId));
actionResponse.setRenderParameter("jspPage",actionRequest.getParameter("mvcView"));
}

public long addFileEntry(ActionRequest actionRequest, long folderNameID)
throws IOException, PortalException, SystemException {

String fileToUpload="filesToUpload";
long fileEntryId=0;
UploadPortletRequest uploadPortletRequest = PortalUtil.getUploadPortletRequest(actionRequest);

com.liferay.portal.theme.ThemeDisplay themeDisplay = (ThemeDisplay) actionRequest
.getAttribute(WebKeys.THEME_DISPLAY);
String[] sourceFileName = uploadPortletRequest.getFileNames(fileToUpload);
File[] files = uploadPortletRequest.getFiles(fileToUpload);
InputStream[] filesStream = uploadPortletRequest.getFilesAsStream(fileToUpload);
for (String fileName : sourceFileName) {
logger.info("SourceFileName : "+fileName);
}
...
...
...
...
...
...
...
return folderId;
}

Hi,
In the controller you are getting "phonePrice" from simple actionRequest . Get the paramater using "uploadRequest" as follows.

String phonePrice= ParamUtil.getString(uploadPortletRequest, "phonePrice", StringPool.BLANK);

Hi,

Sorry for wrong info. I retest again and phonePrice parameter is not sending with or without enctype="multipart/form-data".
Thanks

Hii,
I have referred your solution of using uploadPortletRequest and it also resolved my problem but I am not getting why ParamUtil.getString(actionRequest,"stringname") does not work? And why we need this uploadPortletRequest?

Thanks ,
Ishani Sheth

Hi,

You can't get values from actionRequest if you are trying to upload multipart contant like file.
If your HTML Form's enctype is "multipart/form-data" then you need to use UploadPortletRequest and if your from is just a simple html form you can use ParamUtil.


HTH!

Hi,
In case of enctype="multipart/form-data" , you should get parameters from upload request as follows.

UploadPortletRequest uploadPortletRequest = PortalUtil.getUploadPortletRequest(actionRequest);
File file = uploadPortletRequest.getFile("filesToUpload");
String phonePrice= ParamUtil.getString(uploadPortletRequest, "phonePrice", StringPool.BLANK);

Regards
