Filtering Wordpress Categories Using an Undocumented Hook

In this article, we will briefly cover Wordpress hooks and use an undocumented one in order to manipulate category listings. After some further digging, while it is not listed on the Wordpress filter list, it appears that this “undocumented hook” is mentioned on the get_terms() function reference. So, we’ll call this a somewhat undocumented hook. Anybody who knows me knows that I love Wordpress, if perhaps not more than any man should love a collection of code. I...

Building a Simple Monthly Calendar

In this tutorial we are going to learn how to build a simple calendar in PHP. You have seen many of those calendar date pickers mostly in Javascript. This PHP based one has a slightly different purpose - instead of populating an input field, it outputs links for the different dates and can be used for example as a monthly archive in a dynamic DB-driven site. We will build this calendar following good coding practices and keeping the login in one PHP file and the presentation in one...

Displaying Records in Multiple Columns Using PHP

For this article, i have selected a table members, containing each member's pic and some other text detail. The members will be shown in multiple columns as shown in the picture below.

The only thing we have to take care of is the inner loop creates equal number of columns for each row. If there are no more records the inner loop should print a blank column....

Creating Quality Document Scans

While we can all dream about the world of paper being replaced with computers and electronic documents, we all know that is still only a dream.  In the course of doing my graduate studies, I have often needed to make copies of articles and books reserved in the library.  I've grown accustom to scanning these documents and archiving them with the rest of my course work, and in the process I've learned to make high quality scans, suitable for printing if necessary, and still a ...

Libvirt and Python

The previous example illustrated the control of domains using the command-line utility virsh. Let's now look an example of domain control using Python. Python was the libvirt-supported scripting language and provides a clean, object-oriented interface to the libvirt API. In this example, I explore some of the same operations that I demonstrated with the virsh utility (list, suspend, resume, and so on). The...
