View source for Upload images in questionnaire

= Introduction =

We have a client who wants respondents to be able to upload images in a questionnaire

= Solution =

When the recipient open the answersheet to answer, we will create the new folder whose name is recipient's name under the questionnaire then store the images that the he uploads in the image tab of this new created user.
[[File:Question.jpg]]


= How to do it  =

== Requirement  ==

*The user template must have the navigation access to open the Image tab of the Folder and upload the images in this image tab.

== Step 1: Create the group containing the recipients  ==

In the group list, create the group containing the recipients and grant the needed navigation access to this group 

== Step 2: Create the new folder for the recipient ==

(You can see the script in the workflow whose resource id is 45408 in cg.catglobe.com)

<source lang="javascript" line="1">

array para = Workflow_getParameters();
number userId = para[0];

number ImageFolderResourceId = 45406;
number FolderTemplateResourceId = 2071;

array newFolder ;
number userResourceId = User_getResourceIdFromUserId(userId);
array userinfo = User_getUserByResourceId(userResourceId);

string ExistedFolderName = getNameFromResourceUniqueId(ImageFolderResourceId) + "\\"+ userinfo[USER_NAME];
array ExistedFolder = Folder_getFolderByName(ExistedFolderName);

if (ExistedFolder == empty) 
{
newFolder = Folder_new(userinfo[USER_NAME],FolderTemplateResourceId ,ImageFolderResourceId); 
Folder_save(newFolder);
}
else 
{
newFolder = ExistedFolder ;
}
array permissions = {{userId , "FullControl"}};
updateUserPermission(newFolder[FOLDER_RESOURCE_ID], permissions);
string guid = getResourceGuid(newFolder[FOLDER_RESOURCE_ID]);
return getResourceIdFromGuid(guid);

== Step 3: Set up the questionnaire ==

=== Step 3.1 : Create the dummy question for storing the folder id ===

We will call the workflow in step 2 to get the new created folder id of recipient

=== Step 3.2 : Add the following script to the questionnaire ===
