1) In your server script, try to set the container field into a $variable and set that variable as the attachment.
- I have not tested, but it should be possibly
2) FMS has native access to the document folder withing the FMS folders. Anyway, you should never, ever touch files in the folders of the external storage. You must see them as integrated parts of the database.
3) Belive you got the answer above.
You could go with a plugin on this. E.g. the mailit plugin can send several attachments (while the built-in mail function only allows for 1) and the plugin can get the files from the container fields. And run as server side plugin.
Several other plugins can do the same.
Has Mailit been updated to work with SSS on FMS13? Or is it better to go with another plug-in. Are you aware of any plug-ins that have good sample files for SSS?
FMS require 64-bit versions of plugins in order to run server side.
Check with the vendor for 64bit versions. Most vendors is in the process of rewriting their plugins.
Mailit is the best and most stable, full blown mail plugin, I have used.
Any news about 64-bit version of Mailit? Nothing on their website...
