[TYPO3-dam-devel] How to use DAM in an own extension

[Lorenz Ulrich]

Hi Tim

If you read the dam_frontend code you will see that the DAM indexer is 
only used to gather the metadata, not to store it. See this line:

$indexer->setDryRun(true); // just getting metadata from the dock

DAM uses TCEmain to add new records and TCEmain needs a backend user 
which has rights to write to tx_dam and its fields. So just creating a 
backend object in frontend context doesn't mean that a backend user is 
actually authenticated.

The addDocument method in dam_frontend is the most simple way to achieve 
what you want... get the metadata from the indexer, but write it with 
t3lib_db ($GLOBALS['TYPO3_DB']).

I'm not familiar with t3lib_userAuth and its children so I can't help 
you in finding another way since I don't have the time to dig into it.

Best regards,

Lorenz
