Priority enhancement for batch upload of files

[sgoodswen]

Currently, there is an [upload files] option in Edit Sample to attach one file to a sample at a time. There are hundreds of files to upload and an urgent enhancement is required to batch upload files (this was mentioned at the Lab meeting that you recently attended).

Ideally, the upload program would read the files in a directory and upload the file to the appropriate ACAD Sample ID taken from the file name.

Here are some examples of the filenames:

ACAD15627A.JPG‎ ACAD15627B.JPG ACAD15631A.JPG‎ ACAD15631B.JPG‎ ACAD15638A.JPG‎ ACAD15638B.JBG ACAD15640A.JPG‎ ACAD15640B.JPG‎ ACAD15658A.JPG‎ ACAD15658B.JPG‎

For example, 2 files (ACAD15627A.JPG and ‎ ACAD15627B.JPG) Would be attached to the SAMPLE ID ACAD15627
