[FLOW3-general] Persisting resources

[Adrian Föder]

Hello list,

please consider the following structure:

https://gist.github.com/1313125



I would like to do an "ajax"-like iframe file uploader. So I have an 
iFrame where I put a file and upload it. After uploading it should give 
me a/the resource pointer back, besides ideally the image itself.
If an error occurs (or a validator fails, e.g. wrong measurements or no 
image file at all [*this calls for a generic ImageFileValidator ;-)], I 
would like to display that error.

What I gist'ed here are just trials, but actually it half-way works: the 
uploaded image file is stored as file in my Data/Persistent/Resources 
folder AND an appropriate record in the database-table 
typo3_flow3_resource_resourcepointer is created.
Two things are missing: an entry in the ...resource_resource table (i.e. 
the persistence of the Resource object) and an idea how I could send 
information back, like the image itself and identity information.

After all I would like to get the pointer back so I can inject this 
pointer inside the "parent" object's form. After saving that object the 
wiring is done.


Consider the composing progress of a web-based email: You have an 
(anonymous, not-yet-identitie'd) Email open where you can type To:, CC:, 
text, and add attachments. The attachments have to be uploaded parallely.


Thanks for your ideas,

best,

adrian
