[development] D7 File API

[Peter Anderson]

Hi Randy,

I had a look at the File API handbook you linked to, and I guess 
file_usage_add() is what I need, however I tried implementing it and no 
new records are showing in the {file_usage} table...
Here's the code: file_usage_add($uploaded_file, 'block_icons', 'block', 
$bid);
(I got $bid from the {block} table)

My module allows users to upload an image to each block on the site, so 
I created my own database table where each block that has an image 
associated with it is listed.
If I don't need to store the path to the images anymore, I'm assuming 
file_usage_add() does that for me somehow...?
