How str NULL

lovemf · **Author**

Code:

    decl String:Name[MAX_LINE_WIDTH];
    GetClientName(client, Name, sizeof(Name));
 
    if( StrContains(Name, NULL_STRING, false)!= -1)
    return;
    SQL_TQuery(db, InsertPlayerDB, query, client);

this right? sorry my bad english,thanks.

Code:

decl Name[MAX_NAME_LENGTH] // MAX_NAME_LENGTH is predefined
GetClientName(client, Name, MAX_NAME_LENGTH) // using that instead of sizeof() saves the work of figuring out how long the string is.

if (strlen(Name) == 0) return

or perhaps

Code:

if (Name[0] == 0) return
//...

would be better since that's even less work.

though why would it be empty? just wait until one's been retrieved. if the player really has a null string for a name then just save yourself and other players the hassle and kick/ban them right away because they're more than likely a griefer.

Wrong, sizeof is calulcated at compile time, so it's not slower, and not using it gives you a lot of headaches if one of the string sizes changes.

Your second example would be the fastest, you can even do:

Code:

if(!name[0]) return;

To quickly check if the string is empty.
