It is no longer necessary to use a loop to determine whether your visitor has selected one of the buttons in a radio button group. We can now get a true or false response from a single statement (admittedly one that uses a few built in methods in combination).
Just as with any actual programming language, once you move beyond the trivial, there is more than one way that you can write code to achieve the same end result. Here we take an example that is just barely complicated enough to not be trivial and show the difference between several different ways that it could be coded in order to work out which is best.
A question about how to add optgroups to dynamic dropdowns led to my reexamining the approach I had previously used for the examples of how to generate select lists dynamically. As a result I now provide a far shorter and flexible solution.

If you want a second domain to point to the same place as your main domain of your hosting, you use the Park domain option. To point a second domain to the same site as one of the add-on domains on your hosting requires a different approach.
Regardless of which operating system you are using these days you should have at least two logins set up on it – one with administrator access and one without. You then use the login without administrator access for everyday use and only use the administrator account when you really need to do something that needs that access. By doing this you ensure that even if something gets past all the other security you have in place nothing that requires administrator access will be able to be run without your knowledge (and most installs require that access so viruses etc will not be able to install things on your system).
One problem is that while you will give your everyday account a your own username, the administrator account gets a default username when it is first created. This means that someone only has to guess the password to break into it instead of having to guess both the username and password. It is therefore not only the account people would prefer to break into but is also the one that will be easier to break into – unless you change the username to something different from the default.

You don’t want to display all your errors for the world to see so when you create web page you will want to check that they actually display correctly before you upload them to the web.
It isn’t possible to style a file input field directly but we can make the field transparent so as to display whatever we place behind it. Here we place our file input in front of a button and a text field so as to make the file input display the way it does in Google Chrome and Safari in all modern browsers. We have already looked at how you can style a button so you can figure out the rest easily enough.
