Would you consider using preg_* instead of ereg?
Is "ñ" a letter? Is "" a string containing only letters?
Assuming 'yes' to both questions, try
if (preg_match('/^[[:alpha:]]*$/', $variable)) {
echo 'All letters.';
} else {
echo 'Not all letters.';
}

Can the string start or end with a (single) comma?
Assuming 'no', try
if (preg_match('/^[[:alpha:]]+(?:,[[:alpha:]]+)?$/', $variable)) {
echo 'Match';
} else {
echo 'No match.';
}
