To attach the trellis netting to vertical pvc pipes with holes drilled
for wire or nylon string, one can put zip ties through the hole. I
have it zip-tied to recycled steel chain link fence posts, with a zip
tie around the post (you could do that, too). The key is to have a top
rail, a horizontal pipe running from post to post the long way. (Mine
are recycled chain link fence top rails.) Attaching the trellis to the
top rail basically keeps it in place vertically.
I ran it down one row, wrapped around on the end to provide a 4'
wide trellis on the end of two rows. With 4x8 beds and posts at the
corners, one could go completely around the thing and only need zip
ties at the top on the sides and on whatever corner one started on.
My top rails are only 6' high, so I have the bottom of the trellis material
a foot off the ground.
Peaceful Valley has some that is 6-1/2' tall, but they only list 15' lengths,
so one would need more one than piece per bed:

Here is a photo of someone using this stuff on a conduit framework:

He has the conduit attached to the wood base on his raised bed with
metal, U-shaped conduit clamps, with a 2' piece of rebar pounded into
the ground beside the bed and the vertical conduit posts slipped down
over them:
