+ Here is the call graph for this function:

◆ createFile()

ilObjContainerDAV::createFile (   $name,
  $data = null 
)

Creates a new file in the directory.

Data will either be supplied as a stream resource, or in certain cases as a string. Keep in mind that you may have to support either.

After successful creation of the file, you may choose to return the ETag of the new file here.

The returned ETag must be surrounded by double-quotes (The quotes should be part of the actual string).

If you cannot accurately determine the ETag, you should not return it. If you don't store the file exactly as-is (you're transforming it somehow) you should also not return an ETag.

This means that if a subsequent GET to this new file does not exactly return the same contents of what was submitted here, you are strongly recommended to omit the ETag.

Parameters
string$nameName of the file
resource | string$dataInitial payload
Returns
null|string
Exceptions
Exception

BadRequest

Exceptions
Forbidden
NotFound
