I normally would not cover an issue this basic, but I receive requests almost every week for answers from aspiring (OK, call them newbie) web developers who cannot see the images on their web pages after using FileZilla or another FTP utility to transfer HTML and image files to their web site.

There are times when you want the printed output from a web page to look different that the way the page is displayed on a computer screen. This is particularly useful with blogs and web sites that provide information that users may want to print and file away for later use or for late night reading. I am amazed at the number of major web sites whose pages cannot be printed properly because the content either doesn’t fit on the page, or is cluttered with ads and menus that have no useful purpose on a printed page.

Netiquette, or Net etiquette, is a set of guidelines for content and web site design that seek to create a seamless communications channel with users and to avoid areas that sometimes cloud or confuse the communications. Many rules that have become bona fide standards for print media do not work well with the Internet. It is a mistake to assume that all standards used for books, brochures and print media advertising work equally well with the web. Here are some examples of bad netiquette.

We have been using PHP and MySQL for web development almost exclusively for several years. During this time, our team has come up with a list of simple, yet powerful one line SQL statements that make MySQL easier to use. We thought we might share them with you.

It is common to add a drop-down select box that is populated with USA states or Canadian provinces to PHP applications. There are basically three ways to do this. You can hard-code all of the Select box selections into your application, you can add the states to a MySQL database manually, or you can use the handy code on this page to create a States table in MySQL in just a few seconds.

A shopping cart is an essential component of every e-commerce site. Although there are literally hundreds of shopping carts to choose from, only a few stand out. PHP is the preferred shopping cart language because it is the most popular web development language on the Internet. When combined with the MySQL database, PHP is unbeatable for cost effectiveness.
