Developing a Responsive Website: Background Images

A while back we took A Look at Responsive Web Design and how different designers utilize it in different ways.  Now that we’ve seen a few examples in action, let’s create a responsive website of our own.  In this installment we’re going to set up the structure of our homepage and add in a few media queries that will help the site load quicker, navigate better, and keep our desired appearance across multiple devices, platforms, and resolutions. Before we dive in to the HTML, let’s cover the “viewport”...

Building a PHP Ad Tracker: Creating the Database Tables

For the vast majority of modern websites, advertising is a major source of revenue. Banner ads for services related to the web site owner’s industry allow customers to view products that tie into the site owner’s core business. In exchange, the web site owner can charge the banner ad owner for every impression (banner ad appearance) or click-through (when a user clicks the banner ad). In order to build a banner ad management system, we must first create the database tables that will hold the ad information,...

Designing a Clean Website Part 4: The Secondary Page

This week we’re going to finish up our series on how to develop a clean website by laying out a secondary page. We’re going to include a secondary navigation bar along the top of our design, as well as include all of our text for the section on one page.  This will eliminate the unnecessary loading of other pages when all that’s changing is the text.  It will allow the visitor to browse your site quicker and be less work for you to develop. When all is said and done, this is what you’ll have developed:...

PHP Arrays: Defining, Looping and Sorting Simple Arrays

Unlike scalar variables, which assign only a single value to a variable, an array variable can hold multiple values. Arrays are useful for holding values from database queries or web form entries, where each field (also called a “key”) holds a specific value. Let's take a look at how we define some of the arrays we use in PHP.Numbered Arrays. If the programmer does not specify a key for each value in the array, PHP automatically numbers the keys, starting from zero. This code defines an array $arrMonths[],...

PHP User Survey Part V: Administration Layer

In the last piece on our PHP online user poll, we look at the administrative service and how the site supervisor enters, deletes and manages the poll data. The first poll administrative page checks if the administrator is logged in. You can choose from Session variables or Cookies to check the site administrator login status. Once the application has confirmed the identity of the site administrator, the page lists the available polls. The first step is to use the class methods and variables in the class.polls.php...

PHP User Survey Part IV: Presentation Layer

So far in this series, we have developed the data layer (database tables) and the business layer (PHP methods) for manipulating the data. In this piece, we will look at the presentation layer that is used to display the poll question and poll results. The HTML header will check for the presence of a cookie (in case the user has voted previously) and refresh the page if it has timed out. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">...

Designing a Clean Website: Navigation

There is one design style that can withstand the fluctuating trends that come and go in the design world, and that is to have a clean, simple, minimalist site. Think of sites like Apple, Amazon, and The New York Times. One thing you will notice that they all have in common is perfectly executed use of white space. However, there are some very subtle guidelines to follow or tips that you should consider when designing your own clean website. This tutorial will take you through the development process and...

PHP User Survey: Setting Variable Values and Reading from Tables

In Part I of this series, we started the process of creating user polls for a business web site. Part I gave the layout of the data layer and began the construction of the class file.  In this part we will continue with adding methods to the class file that will enable the administrator to set the variable values and read from the database tables. The setPollId($iPollId) method sets the value for the _iPollId variable.  Since the constructor method calls the setPollId($iPollId) method, we must...
