I want to give an attachment option in the course that I am creating where the learner should attach other certificate then only he can move forward in the course. What are the steps to do this?
Unfortunately this isn’t possible - the ability to upload and store an attachment is something that has to be handled by the Learning Management System the course will hosted on and launched from once published.
The most common standard supported by Learning Management Systems is SCORM - so that’s what Evolve supports.
Unfortunately the SCORM standard provides no mechanism for handling uploading attachments, therefore Evolve does not support it either.
If you already have some mechanism in place to allow for uploading and storing attachments like a certificate then you do have an option for doing what you want in Evolve: but it is advanced functionality and would definitely require work from a web developer to create a custom ‘Certificate Upload’ web page which you could display in Evolve via the iFrame component.
