------ Solution --------------------
You have not set the permission to upload. it means that mkdir () is rejected and extension is not enabled.
------ Solution --------------------
Notice: Use of undefined constant tmp_name
Note: an unspecified constant tmp_name is used.

Solution: add the 'tmp _ name' quotation mark to it. Alternatively, you can disable the Notice error level by setting php. ini (you can use [tmp_name ).
