However, all of my data is saved to an external db. Is there any documentation available for saving the signature image’s local path to an external db? Right now if I use the form’s database settings to insert, I assume it tried to insert the actual image which ends up being corrupted.
I read over my original question and realized it was not specific enough. What I would like to do is be able to set the local path in a function where the signature png files would be stored, and save that path with the complete signature file name to the external database.
Set local root path: /volume/pool/signatures
so if the signature file is named: signature-0820389.png
I’d like the path to be saved to the table: /volume/pool/signatures/signature-0820389.png
And save the image to that path, not the database.
