Hi, what battery type should I be looking for to go on my camper trailer? It has the wires to connect and inside has the bits you plug into.. and what is the best way to charge it? it has a cord that goes from the battery to the car but the previous owner showed me that it had been broken, who would I look at to repair it? and will I need a cover/box for the battery? Thank you

The typical camper batteries are AGM, it will depend on what you want to run and how you intend to charge them as to the size.
Others can explain in more detail, there are simple systems and very detailed systems.
Typical system might be 200ah (Amp Hours) and a 120W to 150W solar panel to charge it when camped. You can get the "cord" repaired and then charge the batteries while driving.
As mentioned, talk to an auto sparkie about what is needed.

Would I need to have it charging while driving and solar panels or just one or the other?
Thank you

Ideally, yes.
A suitable dual core wiring from the main battery and isolator to an anderson plug at the back of the car.
Then anderson plug on the trailer to the AGM.
You can also do it with a DC - DC charger, others with that sort of set up might explain the difference, but either way would be fine.
Solar top off is really for extended stays, if touring with the charging system from the alternator, you wouldn't need to set up solar at all with a decent AGM battery, say min 100 amp/hr to whatever you can afford, 200 amp/hr ?
My arkpak (100 amp/hr) charges fully with half a days driving when touring, or will run the fridge and led lights for a couple of nights no problems when we ever stay anywhere that long.

I'm finding it all to be quite costly, the local battery guys in town said I was looking at $300 for the battery and near $200 for the box.. plus then the plug fixed. How much would I be looking at for the isolator and solar as
well? I've seen solar panels around mostly at the $400 mark if not more.

YEah mate, good AGM not the cheapest, but best for what they need to do . . .
mine was $350.
You can start with anything really though, just get it set up right, and later ou can get a good battery on special etc.
Isolator typically around $100, heavy dual core wiring not cheap though, maybe $10 a metre if you
shop around ?
Battery box, only need a basic one with a couple of 12v ciggy outlets, USB outlets are handy, but you can get a ciggy one with 2 usbs to charge phones etc.
These can be got for
well under $100.
I have this solar panel
Ridge Ryder 100w folding . . . plenty to keep me topped up as long as reasonable sunshine.
Wait for the 20% off, this is then under $320.

To keep costs down, why not set up 2nd battery in the engine bay, and run wire at
camp to the trailer set up ?
If the fridge is in the camper, then obviously that won't work out.
Just keep in minf voltage drop when running wiring a fairly long distance, whether charging 2nd battery, or running wire to power things.

A 100AH Marine battery might be a better choice than AGM, the construction supports the plates better and therefore better on a camper to handle corrugations etc; Cheaper too!

So any options, very confused haha, will have to do a lot of research into them all and get some quotes and see how we go. I don't mind paying a bit more for better quality and longer lasting products but trying to keep costs down a little :)
