Last week we discussed how important navigation is to a website and how developing an interactive navigation system will help give a clean, minimalist website a bit of character and make it feel modern and current. It’s too easy to make a clean website look dated and as though it were developed in the 90’s, so by injecting modern user interfacing techniques that are popular today you’re able to put the viewer at ease and reassure them that the content is fresh and up to date. We’ll pick up where...
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...
Web applications remain the largest security risk for any company. The reason is two-fold. First, most software services have moved to a web based environment giving malicious hackers a much larger landscape to attack. Second, most organizations put a majority of their resources, i.e. dollars and manpower, into network and perimeter security leaving the web unguarded. In most cases, it is up to the web developer to secure sites as best they can. Those who know how to patch known vulnerabilities in...
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">...
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...
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...

Videos have been a great way to attract viewers to a website long before YouTube launched back in 2005. But it wasn’t until the release of HTML5 that web developers have had a lightweight solution to playing the video. In the past, displaying a video on your site meant your viewer was required to have a Flash or Java-based player installed on their system in order to watch the video. This was one more thing that would weigh down your site, causing pages to load slower, and be one more thing you’d...
