Eregi help please

[Dillenger]

I'm trying to validate a form, and I want more than one statement in my eregi... here is what I have so far...

$pattern = "[a-z]";

if (Eregi ($pattern, $customerFirstName)){
echo "Thanks";
} else {
echo "Theres stuff missing";
}

So, I want to be able to add more variables to that, such as $customerLastName and so on... can anyone tell me how this is done?

Thanks,
Dillenger

if (Eregi ($pattern, $customerFirstName) && eregi($pattern, $customerLastName)){ 
//OR you can concat...if (Eregi ($pattern, $customerFirstName.$customerlastName)){ 
//OR just make some nested if statements (not going to demonstrate) - probably the best solution because you can give the user a *specific* problem/solution
echo "Thanks"; 
} else { 
echo "Theres stuff missing"; 
}
