Hi guys, I'm making some commands using dialogs. I would like to know how to do a dialog(DIALOG_STYLE_INPUT) that only you can write words, not numbers.

Sorry for my English.

Search for the IsNumeric code which is somewhere on the forums. Immediately checking w/e a player types is impossible (Unfortunately)

You could use the function IsNumeric or just make your own version. Here's the IsNumeric function.

pawn Код:

IsNumeric(const string[])
{
    for (new i = 0, j = strlen(string); i < j; i++)
    {
        if (string[i] > '9' || string[i] < '0')
        {
            return 0;
        }
    }
    return 1;
}

That's an older version. There may be a newer version out there. I'm not sure if this would return false if there was a string like "f2fs984hg2". If it did say that wasn't numeric then you could just use a loop to search the string for any number.

Well of course it will return 0, if it finds a non numeric character

I use this function, but It returns true if I type something like e3cgf6.

You are probably using it wrong. Show your code

[(SF)Noobanatior]

this is a better one

Код:

stock isNumeric(const string[]) {
	new length=strlen(string);
	if (length==0) return false;
	for (new i = 0; i < length; i++) {
		if (
		(string[i] > '9' || string[i] < '0' && string[i]!='-' && string[i]!='+') // Not a number,'+' or '-'
		|| (string[i]=='-' && i!=0)                       // A '-' but not at first.
		|| (string[i]=='+' && i!=0)                       // A '+' but not at first.
		) return false;
	}
	if (length==1 && (string[0]=='-' || string[0]=='+')) return false;
	return true;
}

Your example has a lot of unneeded stuff.
Also, the 'ultimate' version would be this

pawn Код:

IsNumeric(const string[])
{
    if (!strval(string))
    {
        for (new i = 0, j = strlen(string); i < j; i++)
        {
            if (string[i] != '0') return 0;
        }
    }
    return 1;
}

pawn Код:

printf("%d\n", IsNumeric("0000")); //returns 1
    printf("%d\n", IsNumeric("2341")); //returns 1
    printf("%d\n", IsNumeric("+2341")); //returns 1
    printf("%d\n", IsNumeric("-2341")); //returns 1
    printf("%d\n", IsNumeric("jhb342u")); //returns 0

2 firsts doesn't work, I will try the last one.

Edit.: The last one doesn't work as I would like. If you type 3fdsl It returns 1, as I want, but if I type fasd3 It returns 0, at least it's something.

Thanks all.
