Saving documents into appian when the button submit is false

Hello [mention:fcf3fe8840e344169cca473e354fb852:e9ed411860ed4f2ba0265705b8793d05] 

Could you please share the code snippet of your Upload field and the submit button.

In my applications, I save various meta data to the database when uploading files. This makes managing files much easier on the long run.

Use this function:

You can use a!submitUploadedFiles() function as Stefan said, but please note that if your interface is in a process model (which I assume is because you mentioned about submit: false()) then this function won't work. It works either on a site page, on a standalone interface that is not plugged in a Process. 

You can use a!writeRecords in submit button saveInto for uploading files into db, then a request id is generated (do onSuccess configuration), pass that request id through rule inputs into process model if you need it for whole data need to be saved in DB.
