strcmp not working - Jack_Leslie - 04.04.2015

This should work right?

pawn Код:

for(new i = 0; i < sizeof(pVeh); i++)
                {
                    if(strcmp(pVeh[i][car_Plate], string, false) == 0)
                    {
                        exist = 1;
                        break;
                    }
                }
                if(exist == 1)
                {
                    ErrorMessage(playerid, "That number plate already exists on another vehicle!");
                    format(string, sizeof(string), "You are setting your plate for your %s. This will cost $75 and There's a few guidelines.\n\n* Can only be 34 characters long.\n* Has to be unique.\n* Any unrealistic plates seen will be changed by an admin", GetVehicleFriendlyName(SettingPlate[playerid]));
                    ShowPlayerDialog(playerid, DIALOG_VEH_PLATE, DIALOG_STYLE_INPUT, "Vehicle Number Plate", string, "Submit", "Cancel");
                    return 1;
                }

But when the string is the same, it doesn't run if(exist == 1)

                    return 1;
                }

The above code should work fine Added a (!) before strcmp.
Strcmp returns 0 if string matches and returns 1 or -1 if they don't.

Thats why he checked it...with == 0...to write ! or == 0 is the same

The Problem is, he must write it like this:

PHP код:



if(!strcmp(pVeh[i][car_Plate], string, false) && pVeh[i][car_Plate][0] != '\0')
