alphabets == alpha_simple_capital??
you mean without numbers, slashes, commas ?

if its that you need to make a JS script that runs at the text change so that if the keyCode is not among the 'alphabet' values then its not added to the textbox
or simply a php script which detect it as an error and show the error message :D

for the php script, you'll be getting the input form POST or GET as usual
and then run it through a func. just like the JS one

something like;

function isAllAlpha($str){
//your coding
return true or false
}

if(isAllAlpha($_POST['txt'])) echo "OK";
else echo "Error";

php has isNumeric() and isNaN() functions you could use to check if its a number. Then create an array with all special characters and loop through it to see if the content contains them or use regex to perform a search for numbers and special characters. Its best if you did this on the client end though since it wont burn server resources doing it.

I think regex is good to handle this
Get the input and see if its the type you want with preg_match
