Display custom url if comment authors url is blank
Here is a nifty trick for your comments.php
template. If someone comes to your site and leaves a comment but doesn’t leave a url back to there site, the default link that is shown in place of the php code comment_author_url
is the current page link.
That might not look good. So, here is a little trick that I just implemented into my site. Besides installing the twittar plugin and pulling Twitter avatars I wanted to use the image itself for the authors url like. But if the author doesn’t have a Twitter avatar or a Gravatar it will display a default Gravatar that I set. If the default Gravatar is shown, usually the author will not leave a url link.
I would like to link the image to Gravatar.com so that they can get an image attached to their email address. So.. here is the code:
<?php if($comment->comment_author_url != "") { ?> <a href="<?php comment_author_url(); ?>"><?php gravatar(); ?></a> <?php } else { ?> <a href="http://gravatar.com" title="Get a Gravatar today!"><?php gravatar(); ?></a> <?php } ?>

How to: Add a contact me via Skype™ button
This little trick is really simple and easy. All you need to do is plug this line of code anywhere you would like to use the text.
<a onclick="return skypeCheck();" href="skype:austin.passy?call">Call me on Skype!</a>
That’s is, pretty simple huh? Just make sure you change skype:austin.passy to your user name!
Want a test? Well, please use the text button, as I was getting to many call’s and hangups: Call me on Skype! Message me on Skype!
Thanks to Shayne for this code!
Update:
I was reminded by Shayne that you will have to add this script into your header.php
file:
<script type="text/javascript" src="http://download.skype.com/share/skypebuttons/js/skypeCheck.js"> </script>
That way if the user doesn’t have Skype, they will be prompted to download it if they would like :).

How to: show/hide a widget in WordPress with jQuery
In a previous post I talked about how to show/hide a single div
html code with a search inside. Today I’d like to show you how I implemented jQuery into my new theme.
As seen in the current theme, I am using jQuery to animate the show/hide or as known as the css style display: none;
.
Since I am using a custom child theme on my site, and have Hybrid theme as my parent, the widgets or sidebar section is different than may be in your theme. But just apply the the style’s as follows to your theme.
First make sure that your WordPress site is calling jQuery, by plugging in this code into your header.php
file above the <?php wp_head(); ?>
text:
<?php wp_enqueue_script('jquery'); ?>
Then anywhere above the </head
>, plug this code in:
<script type="text/javascript"> function toggleWidgets() { $('#primary h3.widget-title').addClass('plus'); $('#primary h3.widget-title').click(function() { $(this).toggleClass('plus').toggleClass('minus').next().toggle(180); }); } $(document).ready(function() { toggleWidgets(); } </script>
That’s it. Pretty simple huh.
So lets go over what the code does.
$('#primary h3.widget-title').addClass('plus');
This line finds all <h3>
tags with the class widget-title
inside the ID parameter of #primary
and adds a class of plus
.
Then
$('#primary h3.widget-title').click(function() { $(this).toggleClass('plus').toggleClass('minus').next().toggle(180); });
Will apply a click function. When the H3 tag is clicked it will remove the class plus
and add the class minus
.
Then the code that says .next
will then toggle the “next” element after the <h3> title.
