This is how I upload charts to the Greenhorn website.
To start with, I usually have the charts as JPEG or PDF files. Often when I get them, the files are named in a way that would be irritating and confusing, like this:
Finale Print Music 2009 - [afro blue - Flute.mus].pdf

The first thing I do is to rename the files to something that is easily to recognize at a glance, and easily searchable. The naming scheme I like is
<name of piece>_<key of chart>
like this:
afro_blue_Bb.pdf
Or, if there’s more than once chart for the key, then I like
<name of piece>_<instrument>_<key of chart>
like this:
afro_blue_Trumpet_Bb.pdf

The next thing to do is to upload the charts. We use the WP-Filebase WordPress plugin to manage charts. This is available in the administration dashboard of the site, under the “WP-Filebase” menu item.

Under that menu item, I go to the first item, “WP-Filebase”.

This takes me to the main page of the WP-Filebase upload manager. On that page, I press the “Batch Upload” button.

This takes me to the batch upload page, which looks like this:

For the files to show up as “charts” on the Greenhorn website, they need to be categorized as “Charts”, so in the “Category” drop down of the batch upload page, I choose “Charts”.

Next, I drag the files onto the drag and top target of the web page where it says “DROP FILES HERE”. This uploads the files. The uploading looks like this:

Once that is done, I like to make sure it’s all uploaded correctly. First, I go to the “Files” menu item under WP-Filebase.

This takes me to a listing of all the files WP-Filebase is managing. Here I can see that I uploaded the files, and that they have the correct category. If they’re in the wrong category, or named funny, from here I can rename the files, put them in different categories, remove them, etc.

Finally, I go the the Charts page of the website, and lo and behold, there are the freshly uploaded charts!

That’s all there is to it.
