Detailed Description

Represents virtual root node for all submissions.

Workshop submission uses two fileareas: submission_content for editor's embeded media and submission_attachment for attachments. In both, the itemid represents the submission id. This container is used to display the list of all submissions in these areas (ie when these areas are browsed with itemid == null).

Member Function Documentation

build_search_files_sql()

file_info::build_search_files_sql ( $extensions, $prefix = null )

protectedinherited

Builds SQL sub query (WHERE clause) for selecting files with the specified extensions.

If $extensions == '*' (any file), the result is array('', array()) otherwise the result is something like array('AND filename ...', array(...))

Parameters

string | array	$extensions	- either '*' or array of lowercase extensions, i.e. array('.gif','.jpg')
string	$prefix	prefix for DB table files in the query (empty by default)

Return values

array

of two elements: $sql - sql where clause and $params - array of parameters

copy_to_pathname()

file_info::copy_to_pathname ( $pathname )
