Display player's name in chat and then have their input display next to it


I am looking for some assistance with the following

For example:

/I is happy will display in chat “(playername) is happy.”

I am struggling to locate the specific syntax to get and display the players name in the chat

TriggerEvent(‘chatMessage’, (playername), {255, 0, 0}, command[2], {0,0,0})

I believe I am on the right track. All help appreciated!
