OP, almost all flashes have a hotshoe, i.e. can be triggered by a hotshoe on the camera body. Only niche stuff doesn't have a hotshoe connection, usually things that are not supposed to be mounted on the camera's hotshoe, like ring lights and macro lights mounted on the lens, big flashguns mounted on flash brackets on the side of the camera (including huge old contraptions from the 50's) etc. .
I guess what you mean is that some cameras don't have a hotchoe, and have a coldshoe instead. In this case you need
1. a flash that can accept a PC sync cable, which connects to the camera body (or lens)
2. an adapter that has a pc plug on one end that connects on the camera body (or lens), and a hotshoe on the other end that mounts on your cold shoe, turning it into a hotshoe.
There are some cameras that offer no flash syncing (like Leicas before the III), or that require a special cable (non-PC) like the Contax II or IIa (early models). Or like some cheap digital point and shoots (barring their popup flashes).
Tell us what camera you need to mount that flash on, instead of speculating about a hundred possible cases.
