Re: How do I validate input using php?

you're returning a literal true if the condition matches, and nothing if it fails... function validate() { //

        if ( is_numeric($input1) && is_numeric($input2) && ctype_alpha($input3) &&
        ctype_alpha($input4) )
                return true;
        else
                return false;

    some action;

} My problem is I get the action every time, even though the input is of the right type. And, is ctype_alpha() the only way to check for only alphabetic characters?
