How to serve files in Drupal without using links? -

-

How can I serve files in Drupal without revealing any such link which can be used again? This type of thing is usually handled by PostBack in .NET, for example, but I can not find any documents to complete it in Drupal.

The goal is to be able to give specific file to the user exactly once they complete a series of steps defined by the module. Some eCommerce modules provide some features to support limited file downloads, but I prefer not to set up a complete eCommerce solution to complete a task.

Thanks in advance!

Once you write a module to manage the URL and log in while logging in.

The module will use the function to serve the file from some personal space.

It is not necessary to upgrade that we are a viable alternative to those people who have to deal with the legacy code. Did you try to upgrade SP1? I do not know of any specific problem in this area, but this will be the first change I tried to do.

I am trying to install Ubuntu on a USB, the problem is that I do not want to repeat the boot once, I want to keep my windows, but I want to boot Ubuntu using the virtualbox and USB to the Ubuntu Want to use my hard drive, but how? The virtualbox will not recognize USB as a hard drive when installing an ISO In virtualbox, you have to create a virtual hard disk. Make a USB drive and tell the virtual box to install a virtual hard drive that you just created. EDIT: To answer some more questions: In the new Virtual Disk dialog, click the button next to the location field, click on the button Virtual Disk on Flash Drive To access, click the arrow next to Save in the Select File in the window next to Save In, and you can access your flash drive from there. I recommend setting the image to be allocated dynamically, because the size of your flash drive is not available disk space. I name the image, then select that image to install Ubuntu in the Verbill box. The virtualbox will never...
