How to say "Happy Wedding" in Finnish?

Does anyone here speak Finnish? I could really use some help. I want to send a wedding congratulation to a friend on Facebook since he’s getting married over in Finland...
I’ve been given a few suggestions:
"onnea avioliittoon"

or

"Hawn huora, silloinkin on hyvin onnellinen haawt!"

or

"meillaw molemmilla on poika jo, kerro hawnelle, kun lawhden"

or

"Minaw halusin sinut, mutta se on okei, hiljaa, onnellinen haawt elawmaw"

The thing is, I have no idea what any of these actually mean and I don't want to risk saying something embarrassing... any advice?🤷

Hmm, Google Translate is giving me some really weird results here 🤣

We both already have a son—tell Shawn about it when you see him—we both have a son already , please tell Shawn when you meet up

Here is the simplest way to say it
Wishing you all the best for the wedding! All the best to you guys at the wedding 🤣

Honestly, I don't know a single word of Finnish—Google Translate isn't exactly reliable, so just give it a shot like this 😉

"Onnea avioliittoon" basically means "congratulations on getting married"—so, I guess it's like saying "happy marriage," just a general way to put it

You can definitely use that, or maybe just stick with "onnea."

Oh, come on, forget about Google Translate—it’s honestly pretty useless for this... It feels like my best bet is just to go with the first option...
