How to check if a string contains spaces? - Superthijs - 04.02.2012

Hi, I've made a function to change a player's name, but when I use a space in the name,
the server crashes.
Is there any way to check if a string contains one or more spaces?

Yes, use this:

pawn Code:

strfind(string, " ")

This will return true if it contains spaces, false if not.

pawn Code:

new string[length];
for(new i = 0; i < strlen(string); i++)
{
    if(string[i] == ' ') string[i] = '_';
}

Will replace any space with an underscore.

Thanks!

But it gives a warning...

Code:

if(strfind(NewName, " ") == true) return SendClientMessage(playerid, 0xFFFFFFFF, "{FF0000}/SETNAME{FFFF00}: Spaces are not allowed in a name.");

Warning:

Wrong, wrong, wrong. Read this before posting.

To see if the newName contains a space, use this:

pawn Code:

if(strfind(newName, " ") != -1)
{
    // yes, it does
}

I don't remember strfind returning a boolean...

pawn Code:

if(strfind(NewName, " ") != -1) return SendClientMessage(/* */);

Oops, hehe... It works fine now.
