Change Default WordPress Gravatar in Comments

Hiroshi — Sun, 20 Dec 2009 20:52:20 +0000

If you use a plugin to add avatars to your blog, there might be a setting in the plugin’s options page for choosing the default avatar. If you use WordPress 2.5+, then you probably use a template tag like the following for your avatars.

 echo get_avatar( $comment, 32 ); ?>

You can easily modify this code to show a default customized gravatar to appear if the comment author has no gravater to show.

Just add a comma after the 32 (The pixel size of the image, if you want to change that while you’re at it!), and paste in the URL to your image. e.g.

 echo get_avatar( $comment, 80, 'http://www.yourblogaddress.com/my-gravatar.jpg' ); ?>

Now the comments on your posts will have a much nicer image that draws less attention, promotes recognition of your logo, and as so few blogs have a unique default avatar, it shows your attention to detail.

Hide WordPress WP-Admin Login Page

Hiroshi — Sun, 20 Dec 2009 20:20:05 +0000

Here is a code which you can use to hide your wp-admin screen. Change YOURSECRETWORDHERE to something else. It can be any word you want. Just make sure it’s unique and somewhat long. Make it, like, your pets name or something random. Change ADMINFOLDER to the new folder name you want. Letters, numbers, underscores, and dashes only. That ^ in front of it is on purpose. Don’t delete that. Back up your original .htaccess file before making any changes. I am not responsible for any mess up.

<4>.htaccess Code

RewriteEngine On
RewriteBase /

Customizing WordPress Tags Cloud – A Guide

Hiroshi — Sat, 14 Feb 2009 22:16:11 +0000

If you have already used some social networking website or you are a blogger then you definitely know what the tags are. WordPress offers Tags Cloud which can be customized the way you use it at your blog. By default WP Tag Cloud will generate limited number of tags in alphabetical order. Custom templates for tags can be made which means that you can have a full page of tags as you want it. Look at the 404 page of phpmagicbook. I have used tags to give the users some more options to browse if he gets distracted by ‘page not found error’. I was thinking to give my users all tags option to click at any one. Okay now this is just one use. You can have your own customized tags page which can contain just tags and nothing more. We explore some ways about how we can customize tags/tags template/tags page at our WordPress blog.

Default Tags Cloud

Paste the following code anywhere in your blog theme’s template files (e.g. 404 page, single post page etc.) to see default tags cloud in action:


if (function_exists('wp_tag_cloud'))
wp_tag_cloud();
?>

Display All Tags

Following code will give you all the WordPress tags which you have used in your blog.


if (function_exists('wp_tag_cloud'))
wp_tag_cloud('number=0');
?>

Define Custom Font Size in Tags Cloud

Following code will determine the smallest and largest size in your tags cloud.


if (function_exists('wp_tag_cloud'))
wp_tag_cloud('smallest=8&largest=22');
?>

Random Ordered Tags Cloud

Following code will generate random tags cloud which will not be in alphabetical order.


if (function_exists('wp_tag_cloud'))
wp_tag_cloud('order=RAND');
?>

Tags Cloud Limited in Size & Ordered by Number of Posts

Following code will generate custom font sized tags cloud ordered by post frequency under a specific tag.


if (function_exists('wp_tag_cloud'))
wp_tag_cloud('smallest=8&largest=22&number=30&orderby=count');
?>

Tags Cloud Format

You can format Tags Cloud in flat (Default) format – separated by whitespace, list format and array format by using following method:


if (function_exists('wp_tag_cloud'))
wp_tag_cloud('format=list' );
?>

And there is ASC (Default), DESC and RAND order for Tags display order.
Exclude and Include option to exclude and include tags and more…

Mixing Things Up

And finally with a bit of a magic you can add the bits and bytes into a full story of customized Tags Cloud for your own blog. A possible combination of code and example:


if (function_exists('wp_tag_cloud'))
wp_tag_cloud('smallest=8&largest=22&unit=pt&number=50&format=flat&orderby=name&order=ASC&exclude=garbagetag&include=mytag' );
?>

Example: Browse Ajax Rain’s tags page to view the full tags option in action.

WordPress has got complete guide about how you can create custom tags cloud page template or how you can customize tags cloud at your blog in a number of ways. Give it a try.

Have your say! Do you like to customize Tags Cloud at your blog or this is not a necessary part?

Insert Adsense After the First Post in Your WordPress Blog

Hiroshi — Sat, 22 Nov 2008 01:34:01 +0000

Adsense advertisment is very popular among bloggers. Many like to display ads on their homepage. Why not after the first post? Here is a very easy way to do so by using a simple php variable as a counter.

The only thing we need is a simple php variable (here named $count) which will count how many posts are listed. If we just listed the first post, we will display the Adsense code.

Here’s the code. Paste it on your index.php file, instead of your WP loop.

 if (have_posts()) : ?>
 $count = 0; ?>
 while (have_posts()) : the_post(); ?>
 $count++; ?>
   if ($count < 3) : ?>
          //Paste the Adsense code here
           the_excerpt(); ?>
    else : ?>
           the_excerpt(); ?>
   endif; ?>
 endwhile; ?>
 endif; ?>
