string_letters(str);
| Argument | Description |
|---|---|
| str | The string to convert to letters. |
Returns: String
With this function you can remove all characters that are not
classed as letters. This is handy for preventing people from
entering unwanted characters into a text entry (like entering "#"
to force a new line).
Note: This function only detects the 26 letter english alphabet
from A - Z.
username = string_letters(username);
The above code will set the "username" variable to only hold the letter characters of the original string.
