I’ve copied and added the ‘Channel’ field code to this Upload Form (from another Form, in this same script) but it isn’t part of the Upload process of this Form. Can you suggest what I might do to integrate it? The added ‘Channel’ field code begins on line 155.
In the php code, have a look at the variables that are being uploaded, and note how it deals with the different types - text, option values and so on. Add some code to get the value of your channel input, and just modify the upload code to display it for now. Once you’ve got it so you can grab the value, then you can look at modifying the php to store it in the database. One step at a time.
