It's been years since I programmed anything with Lua and I've unfortunately forgotten most of what little I knew. I need some help writing, or someone providing me with if possible, a program that players can input their name and a title into a computer and then output to a monitor on top of the computer.
I'd write it myself if I could but I can barely remember how I made my password doors.
Any help would be greatly appreciated. The monitor size is five across and four high if that matters.

--#Finding monitor
local mon
for k, v in pairs( peripheral.getNames() ) do
if peripheral.getType( v ) == "monitor" then
mon = peripheral.wrap( v )
break
end
end
--#Error if no monitor is available
if not mon then
error( "No monitors connected!", 0 )
end
--#Get their input
write( "Name: " )
local name = read()
write( "Title: " )
local title = read()
--#Put it on the monitor
mon.setCursorPos( 1, 1 )
mon.write( "Name: " .. name )
mon.setCursorPos( 1, 2 )
mon.write( "Title: " .. title )

You should get mon with peripheral.find("monitor") instead of that.

Keep in mind, that won't work if koalakyle is using an older version of CC.

I like to keep backwards compatibility :)/>

you could do
if not peripheral.find then
function peripheral.find()
--code
end

KingOfGamesYami's code isn't even particularly great for backwards compatibility. The difference between the introduction of peripheral.find and peripheral.getNames isn't as big as you think.

What about this code then?
for k,v in pairs(rs.getSides()) do
if peripheral.isPresent(v) then
-- do something here
end
end
(I hope I didn't mess up anything.I'm On my phone right now.)

Well, peripheral.getType instead of peripheral.isPresent, but yes, that would cover the most versions that I know of. Of course, it doesn't cover networking cables, so if one were to really want to push for grabbing the first peripheral of a type no matter which version you were on, I might do something like:
function getFirstPeripheral(mask)
local func = peripheral.getNames or rs.getSides
if peripheral.find then
return (peripheral.find(mask))
end
for _, side in pairs(func()) do
if peripheral.getType(side) == mask then
return peripheral.wrap(side)
end
end
end

Thanks a tonne. That's almost exactly what I needed, I realise I wasn't 100% clear, I needed it to be able to store multiple names/titles and display them on a monitor, preferably able to add more names as more players join
Thank you again for your help so far.

Ah, that's an easy modification:
--#Finding monitor (Yes I could do it differently but I'm doing it this way..)
local mon
for k, v in pairs( peripheral.getNames() ) do
if peripheral.getType( v ) == "monitor" then
mon = peripheral.wrap( v )
break
end
end
--#Error if no monitor is available
if not mon then
error( "No monitors connected!", 0 )
end
local players = {}
while true do
--#Get their input
write( "Name: " )
local name = read()
write( "Title: " )
local title = read()
players[ #players + 1 ] = {name = name, title = title}
--#Put it on the monitor
mon.clear()
for i = 1, #players do
mon.setCursorPos( 1, i * 2 -1 )
mon.write( "Name: " .. players[ i ].name )
mon.setCursorPos( 1, i * 2 )
mon.write( "Title: " .. players[ i ].title )
end
end

Yami's revised code will allow you to keep adding names but won't allow you to stop.
You could ask how many names the user wants to type in and loop that many times.
