PHP Ad Tracker: Data Object Design and Coding

In our last PHP Ad Tracker lesson, we constructed the database tables for our ad banner application. Now we are ready to construct the data object that will hold the variables and functions that will display, add, edit and delete the data in those tables. Once we name all of the variables and functions, we will start applying the code to them. Variables: The data object class will hold two variables: one to hold the banner ad ID number from the ads table, and one to hold the database connection information....

Moving Web Page Elements Using The CSS3 Translate Transform

CSS3 offers a wealth of possibilities in terms of visual and interactive effects, even allowing you to create animated elements without the need for either Flash or JavaScript. In this tutorial we'll go through the process of translating a page element using a CSS3 transform. The translate function essentially moves an element by a specified distance along the X and Y axes. You do need to provide browser-specific code to create reliable transforms, but the technique is not particularly complex....

Developing a Responsive Website: The Footer

At this point we’re just about done with the homepage of our responsive website. We’ve got our navigation in place, our background images resize nicely, and our other elements are able to resize and adjust to various screen resolutions. Today we’re going to focus on tying the page off with a footer. I’ve always admired sites that put some thought in to the bottom of their page design. There are certainly times when a footer requires nothing more than some basic contact info and maybe a copyright...

Creating and Manipulating Modal Popups

Occasionally, I have needed a web page to call a child page in order to display information or to be used in a way to maintain information that will then be re-displayed back on the parent page. I didn’t want the user to be able to get back to the parent page until they have performed some function on the child page. One solution for this scenario is to use Modal Popups.  In this tutorial, I will show how to use JavaScript’s window.showModalDialog() to create a Popup window and display information....

Using HTML5 to Determine User Location

Geolocation is one of the most exciting features offered by HTML5. Using some relatively simple JavaScript code, you can create Web applications that determine various aspects of the user location, including longitude, latitude and altitude plus more. Some Web applications can even provide navigation functionality by monitoring the user position over time, integrating with map systems such as Google Maps API. As with all HTML5 functions, you cannot yet rely on browser support. Where browser...

Developing a Responsive Website: The Homepage Portfolio Slider

We are going to continue on with our designing a responsive website tutorial where we have already learned about the background images, the site's navigation and the content. This week we’re going to work on adding a little more content to our homepage. At this point you should have a site that looks similar to this. You should have a full-screen background image that changes in size to match the viewers screen resolution, a main navigation bar, and a little blurb that will grab the attention of the viewer...

PHP Arrays: Array Functions and Multidimensional Arrays

In Part I, we looked at simple arrays, as well as how to loop through and sort array elements.  In this article, we will look at other array functions as well as multidimensional arrays. The difference between one-dimensional and multidimensional arrays is a simple one: a multidimensional array is a simple array that has simple arrays as elements, rather than strings or scalar variables. Building a Multidimensional Array ... Here is how our $arrBooks example from last week’s article can be expanded...

Responsive Widgets

Responsive design is a hot topic of web development these days, and with a simple (and now well supported) way of handling the ‘one site for all clients’ model (and I mean clients as in browsers/platforms/devices, not the people that give you money in return for a web site) it should well be. Redirecting mobile users to /m/ or some other cut-down area of your site is becoming a technique of the past. Using collections of utilities, such as the excellent 320&up, makes building responsively much...
