Question

Got a quick question, I’m building a big website for a personal project and I think I’m looking at classes and functions for validation of forms and data etc.

My question I guess is:

Can I use a class to house all the functions that will validate dependant upon the data been passed and if so how can I target certain functions within the class (email addresses, phone numbers etc).

If my logic is right how would it look in code format?

Thanks

You could define your validating functions statically within a class. Then include this class as and where you need it.

class Validator {

    public static function validateEmail($email) {
        // validation logic for email
        // return true or false
    }

    public static function validatePhone($phone) {
        // validation logic for phone
        // return true or false
    }
}

// in a different file, where you want to use this class

require('validator.php');
$email = $_POST['email'];

if (Validator::validateEmail($email)) {
    // valid email
} else {
    // invalid email
}
