MongoGridFS::put — Stores a file in the database
filename
Name of the file to store.
metadata
Other metadata fields to include in the file document.
Hinweis:
These fields may also overwrite those that would be created automatically by the driver, as described in the MongoDB core documentation for the » files collection. Some practical use cases for this behavior would be to specify a custom chunkSize or _id for the file.
Returns the _id of the saved file document. This will be a generated MongoId unless an _id was explicitly specified in the extra parameter.
