- 9 core/modules/file/file.module \file_move()
Moves a file to a new location and update the file's database entry.
- Checks if $source and $destination are valid and readable/writable.
- Performs a file move if $source is not equal to $destination.
- If file already exists in $destination either the call will error out, replace the file or rename the file based on the $replace parameter.
- Adds the new file to the files database.
Parameters
\Drupal\file\FileInterface $source: A file entity.
string $destination: A string containing the destination that $source should be moved to. This must be a stream wrapper URI.
int $replace: (optional) The replace behavior when the destination file already exists. Possible values include:
- FileSystemInterface::EXISTS_REPLACE: Replace the existing file. If a managed file with the destination name exists then its database entry will be updated and $source->delete() called after invoking hook_file_move(). If no database entry is found, then the source files record will be updated.
- FileSystemInterface::EXISTS_RENAME: (default) Append _{incrementing number} until the filename is unique.
- FileSystemInterface::EXISTS_ERROR: Do nothing and return FALSE.
Return value
\Drupal\file\FileInterface|false Resulting file entity for success, or FALSE in the event of an error.
