You use strtok to split a player command, and analize separately each word in the command

"/Invitedrift 5"

are two words: "/invitedrift" and "5", both on cmdtext. You can't analize cmdtext within an 'if (strcmp(blabla) == 0)' because you get all the words and it fails on what you want, so your first need is to get the command word. That's why you use strtok for first time

tmp = strtok (cmdtext, idx) // first use of strtok -> you get "/invitedrift"

now you can compare in the if statement.

if (strcmp (tmp, "/Invitedirft", true) == 0)

If the result of the comparison is true, you need to get the playerid to be invited, so again you use strtok

tmp = strtok (cmdtext, idx) // second use of strtok -> you get "5" (or whatever playerid might be)

If it doesn't work, did you set idx = 0?
