In our last session, we showed how to list the ad banner data and client data. In this session, we will examine the form that allows administrators to enter ad banner data. First, we include the class_ads.php file and instantiate the ads class: <?php require_once("class.ads.php"); // instantiate ads class $oAds = new ads; Next, we assign a value for the $id variable by suing the setID function in the ads class: // check for id if ($id) { // assign unique id $oAds->setId($id); } If the form has posted...
If you have read any of the other posts in this series you know that we have done quite a bit with our PHP ad tracker. In this session, we will look at the HTML form that calls these actions. First, we create the HTML table that will hold the form header: <table border="0" cellpadding="0" cellspacing="0"> <tr> <td><b>Developer Drive Advertisements Administration</b></td> </tr> Next, we specify the operation (add/edit/delete/deactivate) for this...
In our last session, we finished writing the PHP class file that would control all the ad banner functions. This week, we look at the presentation layer for the administration of these functions. The ads_list.php page lists the current banner ads. First, we must include the class file so that the page can instantiate the class call the functions: <?php require_once("class.ads.php"); // instantiate ads class $oAds = new ads; Next, we fill the $aAds array with the data from the ads table and get...
Anyone who has played, watched friends play, or briefly saw video games that were released in the 80’s and 90’s is familiar with parallax scrolling. Think of games like Mario Bros, Streets of Rage, Kung Fu, Turtles in Time, or the original parallax scrolling game, Moon Patrol. Parallax scrolling is when there are multiple layers of images all moving at different speeds, causing a 2D image to have a 3D-like effect. Why am I talking about retro video games on a web development site? Well, the simple...
In last week’s lesson, we looked at the variables and methods we would need to interact with the advertising database tables. This week, we’ll examine the code for the data object class file and how the other parts of the site will use these methods. First, we include the database connection string information. This information includes the database server name, cursor location and other pertinent information. Since this information is used throughout the site, it is usually stored in a separate...
This week we're going to finish up the portfolio slider on our homepage that we have already started. At this point, if you view your index.php file and scroll down to the secondary screen it should look something like this. We’re close, all we have to do now is plug in our jQuery elements and then add some CSS to make our secondary portfolio slider screen responsive. Go ahead and download the Java files you'll need from here, keep the js directory in your root folder and check out what out the image below...
The HTML5 Server-Sent event model allows you to push realtime data updates from the server to the browser. In this tutorial we will work through the process, with the EventSource object handling received data and writing it to the page. We will use HTML5 and JavaScript at client side, with PHP at server side. With existing models such as AJAX, the code in a Web page would continually ask the server to supply new data, but the onus was on the client to request the information. With Server-Sent requests, you...
Google Analtyics gives so much data that sometimes it becomes hard to digest. For larger sites it is easy to become so overwhelmed that you can't find the time to look up the analtyics for each page. Or maybe you have many editors for a site who don't have access to your Google Analtyics account and you want to provide them with data so they can see how well their pages are performing. With the Google Analytics API we can easily display some basic analytics right in each page. Google offers many libraries...
