Every web developer should keep useful code snippets in a personal library for future reference. Today, I'm showing you the 10 most useful snippets and functions I have added to my snippet library from the past 3 months.

When coding WordPress themes, especially if you do it regularly, its really useful to have a selection of code snippets in your toolbox to just 'copy-n-paste' as and when the functionality needs. Not just your most commonly used code, but also some snippets that can, when required, extend WP even further.

Snippets are little pieces of code that you can add to your code to enhance it in some way. There are many great Snippets available for WordPress that extend the functionality of your site or change what is displayed on a page.

Excellent source of help for WordPress development. Snippets are a great way to get information on how to complete simple and even complex tasks without having to reinvent the wheel. Very handy tool to have around

I'm sure some of you have seen this before, but It's one of my favorite resources.

Great Wordpress plugin to insert code snippet in post using BBcode. E' possibile definire un numero di token (BBCode) a proprio piacere ed a ciascuno di essi associare uno o più valori (separati da virgole). In fase di rendering della pagina, tutti i BBCode in essa contenuti vengono rimpiazzati con lo snippet di codice relativo, sostituendo a ciascun parametro definito, i valori associati ai BBCode stessi.

"Boost CTR. Improve SEO & Rankings. Supports most of the content type. Works perfectly with Google, Bing, Yahoo & Facebook. What is a Rich Snippet? It is basically a short summary of your page in the search results of Google, Yahoo, Bing and sometimes in the News feed of Facebook in nice format with star ratings, author photo, image, etc"

Great Code examples 

"Tweet2Download allows a wordpress blog to require a tweet and a follow in exchange for the downloads or article parts available on the blog. If you have a blog that provides downloads, this plugin is the perfect twitter marketing tool for you. Tweet2Download allows you to require a tweet and a follow in exchange for a download or a content snippet on your blog. It effectively asks your users to "pay" with a tweet for free content on your blog, making it a very powerfull viral marketing tool."

This article is 1 of 2 in an article set I've named "Ghost Posts". In this article I'll show you how to display random posts grabbed from any category of your choosing in Wordpress without the use of plugins. You can also view this same code snippet being used on JungleJar right now.

JungleJar offers articles, tutorials, rss feeds, tips and strategies, code snippets among many other things to assist webmasters with their respective websites.

The Google URL Shortener API has been released this week so I came up with a short snippet that generates short goo.gl URLs. The script is quite simple, you can paste it in your theme's functions.php file or create a plugin out of it, so without further ado:

Creates a widget, shortcode or PHP snippet for inserting dynamic, highly customizable lists of posts or pages such as related posts or table of content

You may remember a previous article I wrote here on JungleJar.com called Using Custom Fields To Post Your Images, but if not, I'm going to reintroduce a few of the code snippets and methods I wrote about in the tutorial about how to save and display image data from custom fields within Wordpress. In this article I'm also going to cover a few of the small yet robust code block methods I myself tend to practice quite a bit that I didn't previously touch on. So, if you're looking for a solid tutorial on how to use Wordpress Custom Fields to display blog post thumbnails in an easy and flexible manner, then this article is for you.

Two of my favorite web designers with super helpful blogs, Chris Coyier of CSS Tricks and Jeff Starr of Perishable Press, have just released their new collaboration! The book, "Digging Into WordPress," is now available as a PDF download, and if you buy the PDF book now, you will be eligible for a "sweet discount" on the hard copy of the book when it comes out, plus receive updates free. They've done a great job on this book, which covers setting up WordPress, anatomy of a WordPress theme, theme design and development, extending functionality including using WordPress as a CMS, working with RSS feeds, SEO, dealing with comments, and keeping your site "healthy." I already followed both of these designers before they began their collaboration, and have found countless useful tutorials, code snippets, design ideas, and much more on both of their sites - I've relied on Perishable Press as a source for great unobtrusive javascript code, and on CSS-Tricks for all kinds of other useful tools for making valid, functional, and beautiful sites. This book is bound to be a valuable reference to anyone who works with WordPress.
