Wordpress : Using jQuery library with your plugin or theme

lost-in-code — Sat, 28 Jun 2008 23:20:05 +0000

When you develop a Wordpress plugin or theme, you might want to make use of the jQuery library included and distributed with the Wordpress package. The jQuery library is located inside the “wp-includes/js/jquery/” folder. Even though you know what the location of the jQuery library is, I do not recommend that you reference this script using [...]

Wordpress : Translate a Plugin

lost-in-code — Thu, 26 Jun 2008 00:32:38 +0000

First off, you have to know that not all Wordpress plugins can be translated. The plugin developer(s) had to take the necessary steps such as using the Wordpress __() and _e() functions and load_plugin_textdomain() in order to parse the strings/text of the plugin through the localization system. If you have a plugin with the ability of [...]

When you develop a Wordpress plugin or theme, you might want to make use of some of the Javascript libraries distributed with the Wordpress package such as Prototype, Scriptaculous and jQuery. Simple enough, they are in the “wp-includes/js/” folder, so what more is there to it? Can’t I just add a SCRIPT tag in the HEAD [...]

You might need to calculate the date difference in days using PHP. You can easily calculate the days difference by using something like the code below. <?php //date in the past. $date1 = "2008-04-11"; //current date. $date2 = date("Y-m-d", time()); //calculate the difference in seconds. $difference = abs(strtotime($date2) - strtotime($date1)); //calculate the number of days $days = round(((($difference/60)/60)/24), 0); ?> The code shown above takes the [...]

Hash sign/symbol on the Macbook

lost-in-code — Fri, 13 Jun 2008 06:02:33 +0000

I had to get a new notebook yesterday after spilling a cup of green tea on my Macbook pro. I’ve spilled some liquids on it before, but this time the keyboard and trackpad stopped working completely. After using the Macbook for a few minutes, I realized that it doesn’t have a hash symbol, also known as [...]

It allows you to change an array like this : $a[‘b’]; To an object like this : $a -> b; Below is the function.

The Wordpress get_pages function works similar to the get_posts function which fetches posts from the database by criteria. The get_pages function takes different arguments and allows you to take control of parent and child pages as you execute the function. Usage : <?php $pages = get_pages($arguments); ?> Example : <?php $arguments = array( ‘child_of’ => 0, [...]

Embedding a Quicktime movie player into your webpage work similarly to embedding Flash files, making use of the OBJECT, EMBED and PARAM tags inside your HTML code. You can play .MOV, .MP4 and .MPEG files with the embedded Quicktime movie player. As you might know (or have noticed), the Internet Explorer 7 rendering engine “blocks” these [...]

PHP : Strip filename from a URL

lost-in-code — Sat, 26 Apr 2008 06:36:44 +0000

Using PHP, you might need to strip the path from a URL, leaving behind just the filename at the end of the URL. You can achieve this with a regular expression pattern of course, but I have a much simpler solution. See the example code below. $url = "http://www.domain.com/path/to/file/filename.php"; $filename = basename($url); echo $filename; //filename.php And that’s all there [...]
