Is there some updated tutorial or guide on how to best achieve the restriction of channel entries to a specific author/member only?
I checked the documentation, and it seems I would first use the channel forms to create the form that can submit the entry to a channel.
If it helps, I do have the EE Harbor form modules which also seems to integrate with channels, but I was not able to find any documentation on how to do this per registered user/entry. It only has some references to member groups and displaying all entries from a specific channel, not by user.
Registered user “Joe” goes to a template page that contains a form. He saves some data which is an entry into a specific channel.
Registered user “Jane” goes to the same template page that contains the same form, but her submissions uses her ID on the entry. All entries on the channel are unique to avoid duplicates.
Joe then goes to a different template page, but can only see his created entries. Jane is also restricted to her entries only.
I would prefix some random ID on the entry title to make each one unique, but the key part here is to make sure one member cannot access the entry from another member.
If filtering the entries by author enough to achieve this?
For something along the lines of your example. I generally have used the author_id param on the channel entries tag. and set it to CURRENT_USER
author_id="CURRENT_USER" That way Joe sees his entries (and no one elses) and Jane sees hers (and no one elses)
