 | From Scott Orgera, your About Programming Editor This week's newsletter focuses on programming for the Web, featuring tutorials for beginners and experienced developers alike using a mix of languages including Java, Perl and PHP. | |
Building Your First Java Applet
Java applets are like Java applications in that their creation follows the same three step process of write, compile and run. The difference is that, instead of running on your desktop, they run as part of a Web page. This tutorial gets you started with creating a simple Java applet.
| Getting Started With PHP
Learning a new language, programming or otherwise, can be a bit overwhelming. Many people don't know where to start and give up before they even begin. Learning PHP is not as overwhelming as it might seem, however. By taking it one step at a time you'll be up and running before you know it.
| Using Perl or JavaScript to Validate Forms on Your Website
Once you have an HTML form up and running, you will often want to make sure that all the important fields are filled in. For example, if you are going to send an email confirmation letter, the email address should be included in the form fields, and it should be an email address that works. You can validate your forms by using either JavaScript or a CGI script. This tutorial walks you through both options.
| CGI: The Common Gateway Interface
When you are dealing with Web pages, you will often hear people talk about CGI or CGI scripts without ever explaining exactly what that is. Essentially, CGI is the connection (or interface) between a form on a Web page and the Web server. Web pages cannot interact directly with the reader. In fact, until JavaScript came along, Web pages had no way of interpreting reader reaction except through interaction with the server they were running on. This interaction is done through scripts and programs that use common gateway interface to create interactive programs on your Web pages. | |
