This is a helper method to generate the SQL query for the findUploadedFiles and countUploadedFiles methods. Relevant FileRef objects for these methods can be limited by a time range and a specified course. Furthermore, it is possible to limit the search to FileRef objects without a license set or with the "unknown" license set. The amount and the offset of the FileRef objects to be retrieved can also be set.

Parameters

string	$user_id	The ID of the user whose uploaded files shall be retrieved or counted.
DateTime \| null	$begin	The begin of the time range.
DateTime \| null	$end	The end of the time range.
string	$course_id	The ID of the course from which FileRef objects shall be retrieved.
bool	$unknown_license_only	Whether to only query for FileRef objects without a license or with the "unknown" license set (true) or to query all uploaded FileRef objects (false). Defaults to false.
int	$file_limit	The maximum amount of FileRef objects to be retrieved from public folders.
int	$file_offset	The offset in the FileRef data from which to start retrieving objects from public folders.

Returns

mixed[] An array with two indexes:

sql: The SQL query string.
params: An array with SQL query parameters.

◆ incrementDownloadCounter()

incrementDownloadCounter ( )

This method increments the download counter of the FileRef.

Returns: int The number of rows of the file_refs table that have been altered.

◆ isAudio()
