So you click apply you they get presented with the form which is pulling in details from the database/cms and allows you to attach a document which you can then email.
It would be easier if you break your requirements down:
File uploads: Uploadcare seems to be mentioned in the forums as a workaround
Form fields with values from CMS: You already can do this with custom code and basic HTML knowledge
Form is emailed to dynamic email address: You need Zapier to read in the email address field and then forward it to the email address (not sure if Zapier can actually do this - but check it out)
Alternatively, you can implement your own custom email form handler hosted elsewhere.
I set up upload care, all works fine, it is just that i need to notify my client via email when someone uploads something. Or event better to forward the uploads to my client’s email address. The upload field is in a form in a page. Should i set up the forms from settings? If yes how?
