File selector in the front-end of a specific directory

Question

I am developing a component which has a front-end form. In this form it must be possible to select and upload a File to a user-specific directory.

I found and tested the module Easy File Uploader and it fits my requirements for uploading files (I am using the option "Upload to Username subfolders". The module will then create a folder for each user). The component only allows me to upload files, but not select them again. I placed the module in my edit-form of the component.

Now i have a directory like this:

• Images
  • User1
    • File1
    • File2
    • File3
    • File4
    • ...
  • User2
    • File1
    • ...

Now i want to be able to select the files again. (So I can store the filepath for the profile image into the Database) I thought about using a simple dropdown, but how can I realize it with the mvc pattern of joomla 3.3?

EDIT:

Oh, im a bit blind, so I found the form field "filelist" on the joomla docs: http://docs.joomla.org/Filelist_form_field_type

Is there a way to set the directory in the code dynamically?

Answer 1

In your model, after loading the form, you can use setFieldAttribute to set the directory dynamically like so:

$form->setFieldAttribute('myfile', 'directory', 'media/media/images');
