In this post I will present how to quickly add a “Categories” entry to the menu of a WordPress standard theme. Because I am by no means an expert in WordPress and PHP yet, I wanted to avoid having to customize anything.

So here’s the trick:

In the Dashboard > Appearance > Menus section add a new entry under Links with the URL set to “#” and Link Text set to “Categories”. Once you’ve done click Add to Menu and then from Categeories pull and drop in the Menu Structure the ones you want displayed as sub-items under the newly created entry.

Since the source code for Podcastpedia.org is now open on GitHub for everyone to have look at and contribute to, I might as well add a ribbon on the website celebrating that. After a short research on the web, I stepped over Simon Whitaker’s project github-fork-ribbon-css which I could easily integrate in  the website:

Source code for this post is available on Github - podcastpedia.org is an open source project.

In this post I’ll present the two simple steps required for that:

How to display element in JSP only if model element not null

To do that you can use the or _ tags to make conditional rendering in Java Server Pages (JSP) using the JSP Standard Tag Library (JSTL) like in the following code snippet:

<div>
	<c:if test="${not empty podcast.twitterPage}">
		<a href="${podcast.twitterPage}" target="_blank" class="icon-twitter-producer producer-social"></a>
	</c:if>
	<c:if test="${not empty podcast.fbPage}">
		<a href="${podcast.fbPage}" target="_blank" class="icon-facebook-producer producer-social"></a>
	</c:if>
	<c:if test="${not empty podcast.gplusPage}">
		<a href="${podcast.gplusPage}" target="_blank" class="icon-google-plus-producer producer-social"></a>
	</c:if>
</div>

Podcastpedia.org on GitHub

We use currently for Podcastpedia.org a MySQL database and because we’ve recently gone open source on GitHub, we’ve created a README.md to explain the setup of the database. The content of that file is basically reproduced here, as “back-up”, for future reference and why not?, it might also serve others in the mean time.

Note: Although the steps presented here refer to the database backing Podcastpedia.org, they should be valid for any MySQL database you might want to setup either in Linux or Windows.

In this post I will present you a simple trick about how to make the length of the text shown in a paragraph responsive. The example presented is written in Java Server Pages (JSP) and makes use of JavaServer Pages Standard Tag Library (JSTL), but you can use the same trick with other technologies and media queries as you will find out in the coming paragraphs.
