only letters - Kraeror - 07.12.2018

Hello guys I need to check if in the string is only letters, so I created a stock for this, but it doesn't work.
Here is it:

PHP код:



stock OnlyLetters(text[])

{

    for(new i = 'a'; i <= 'z'; i++)

    {

        for(new i2 = 'A'; i2 <= 'Z'; i2++)

        {

            new string[256], string2[256];

            format(string, sizeof(string), "%c", i);

            format(string2, sizeof(string2), "%c", i2);

            if(strfind(text, string, true) == 1 && strfind(text, string2, true) == 1)

            {

                return 0;

            }

        }

    }

    return 1;

}

Please help

You need to loop from position 0 until string's length-1.
Check each character if it is in range of 'a' to 'z' OR 'A' to 'Z' using array index (in example text[i]).
But it is better to do it the other way around. If a character is not a letter, return 0 right away to avoid needless loop iterations.

I don't want to check the player's name. I want to check in my gang system if there are only letters. I don't want gangs with names like: Gr0ve Street Fam1l1es or "12541265zdwas" gang

****** gave you the code that uses Pawn RegEx plugin and told you the method to check it. There's nothing related to "player's name" - it can be used for any text (string).

I did it, but it didn't accept the spaces. I mean "Grove Street" is not accepted. It has to be "GroveStreet". How can I allow the spaces?

Re: only letters - Kraeror - 08.12.2018

I think I did it, I just pasted a space inside the brackets:

^[a-zA-Z ]+$
