)

Move a file to the deletion archive.

If no valid deletion archive exists, this may either delete the file or throw an exception, depending on the preference of the repository

mixed$archiveRelRelative path for the archive location. Relative to a private archive directory.
Returns
Status

◆ deleteBatch()

FileRepo::deleteBatch ( array  $sourceDestPairs)

Move a group of files to the deletion archive.

If no valid deletion archive is configured, this may either delete the file or throw an exception, depending on the preference of the repository.

The overwrite policy is determined by the repository – currently LocalRepo assumes a naming scheme in the deleted zone based on content hash, as opposed to the public zone which is assumed to be unique.

Parameters
array$sourceDestPairsArray of source/destination pairs. Each element is a two-element array containing the source file path relative to the public root in the first element, and the archive file path relative to the deleted zone root in the second element.

MWException

$findItem = [ 'title' => $title, 'private' => true ]; $findBatch = [ $findItem ]; $repo->findFiles( $findBatch );

No title should appear in $items twice, as the result use titles as keys

Parameters
int$flagsSupports:
  • FileRepo::NAME_AND_TIME_ONLY : return a (search title => (title,timestamp)) map. The search title uses the input titles; the other is the final post-redirect title. All titles are returned as string DB keys and the inner array is associative.
