As you know, the user login box of the website contains the following fields username and password. Furthermore, most of them put the “Username” inside user name field and “********” inside password field to save the space within designing.In this post I’ll show you how to show “Password” text in the password field. It doesn’t actually does so but this tips will make it looks like so.
How it’s done
The type of field cannot be changed with Javascript from type=”text” to type=”password” so there are actually two fields for the password: a regular password field, and a second plain text field with the default “Password” value.
When the page is loaded the CSS makes the plain text field hidden. Then the jQuery / js makes the password field hidden and the plain text field visible. It’s best to do it this way so if Javascript is not enabled (or there’s a Javascript error which causes the rest of the script to stop running) then the user still has a regular password field with obscured text.
When the user clicks the plain text field, the jQuery / JS code makes the plain text field hidden, the password field visible and puts focus on the password field. On blur, if the password field contains an empty value the plain text field is restored as the visible one to show the default value.

You will get black background if you resize a transparent image. To fix it, You need set alpha channel imagecolorallocatealpha to 127. With imagecolorallocatealpha, it will allocate a color for an image.
Usage:
int imagecolorallocatealpha ( resource image, int red, int green, int blue, int alpha)
From PHP manual:
imagecolorallocatealpha() behaves identically to imagecolorallocate() with the addition of the transparency parameter alpha which may have a value between 0 and 127. 0 indicates completely opaque while 127
indicates completely transparent. Returns FALSE if the allocation failed.
Before using it, you must set to false the blending mode for an image and set true the flag to save full alpha channel information.
Description: phpThumb() uses the GD library to create thumbnails from images (JPEG, PNG, GIF, BMP, etc) on the fly. The output size is configurable (can be larger or smaller than the source), and the source may be the entire image or only a portion of the original image.

If you have a wordpress blog with one or more author, then it is most important to list author details in the wordpress post pages. The followings functions will help you list out author details such as
the_author
the_author_description
the_author_login
the_author_firstname
the_author_lastname
the_author_nickname
the_author_ID
the_author_email
the_author_url
the_author_link (Version 2.1)
the_author_aim
the_author_yim
the_author_posts
the_author_posts_link
wp_list_authors
Okay, will discuss in detail below,
the_author
Description: it displays Author’s ‘Public’ Name
Syntax: <?php the_author(); ?>
Example: <p> this post was written by <?php the_author(); ?></p>
the_author_description
Description: Displays the contents of the about yourself field in an author’s profile (Administration > Profile > Your Profile). About yourself is a block of text often used to publicly describe the user and can be quite long. This tag must be used within The Loop.
Description: This tag displays the login name of the author of a post. The login is also referred to as the Username an author uses to gain access to a Wordpress blog. This tag must be used within The Loop
Note: It’s usually not a good idea to provide login information publicly. But it can be used for some other purposes
Description: The following tags display the name for the author of a post. The First Name field is set in the user’s profile (Administration > Profile > Your Profile). This tag must be used within The Loop.
Example: <p>This post was written by <?php the_author_firstname(); ?></p>
the_author_ID
Description: Displays the unique numeric user ID for the author of a post; the ID is assigned by Wordpress when a user account is created. This tag must be used within The Loop.
Syntax: <?php the_author_ID(); ?>
Example: <a href="/blog/index.php?author=<?php the_author_ID(); ?>">View all
posts by <?php the_author_nickname(); ?></a>
the_author_email
Description: This tag displays the email address for the author of a post. The E-mail field is set in the user’s profile (Administration > Profile > Your Profile). This function must be used within The Loop.
Note that the address is not encoded or protected in any way from harvesting by spambots
Syntax: <?php the_author_email(); ?>
Example: <a href="mailto:<?php the_author_email(); ?>">Contact the author</a>
Secure your author’s email:
This example partially 'obfuscates' address by using the internal function antispambot()
to encode portions in HTML character entities (these are read correctly by your browser).
Note the example uses get_the_author_email() function, because the_author_email()
echoes the address before antispambot() can act upon it.
Description: This tag displays the URL to the Website for the author of a post. The Website field is set in the user’s profile (Administration > Profile > Your Profile). This tag must be used within The Loop.
Description: This tag displays the AOL Instant Messenger screenname for the author of a post. The AIM field is set in the user’s profile (Administration > Profile > Your Profile). This tag must be used within The Loop.
Syntax: <?php the_author_aim(); ?>
Example: <p>Contact me on AOL Instant Messenger: <?php the_author_aim(); ?></p>
the_author_yim
Description: This tag displays the Yahoo IM ID for the author of a post. The Yahoo IM field is set in the user’s profile (Administration > Profile > Your Profile). This tag must be used within The Loop.
Syntax: <?php the_author_yim(); ?>
Example: <p>Contact me on Yahoo Messenger: <?php the_author_yim(); ?></p>
the_author_posts
Description: Displays the total number of posts an author has published. Drafts and private posts aren’t counted. This tag must be used within The Loop.

Example: <p><?php the_author(); ?> has blogged <?php the_author_posts(); ?>
posts</p>
the_author_posts_link
Description: Displays a link to all posts by an author. The link text is the user’s Display name publicly as field. The results of clicking on the presented link will be controlled by the Template Hierarchy of Author Templates. This tag must be used within The Loop.
Syntax: <?php the_author_posts_link(); ?>
Example: <p>Other posts by <?php the_author_posts_link(); ?></p>
wp_list_authors
Description: Displays a list of the blog’s authors (users), and if the user has authored any posts, the author name is displayed as a link to their posts. Optionally this tag displays each author’s post count and RSS feed link.
Syntax: <?php wp_list_authors(‘arguments’); ?>
Example: <?php $defaults = array(
'optioncount' => false,
'exclude_admin' => true,
'show_fullname' => false,
'hide_empty' => true,
'feed' => ,
'feed_image' => ); ?>
By default, the usage shows:

The following are percept by me, when I go through the net for comparison of shopping cart.
A website with selling products is having good content, and a content site that is indexed can very easily leverage its traffic and sell products. The open source carts and CMS are somewhat related and there is a way to take the core OSCommerce shopping cart functionality and put it into the admin of a CMS.
Virtuemart is a branded version of this attempt. If you look at the admin of Virtuemart it would look like a Joomla/Mambo admin but you would see a new menu option which opens up a OSCommerce shopping cart functionality.
In short if you have Virtuemart then you have OSCommerce. If you like OSCommerce you are better off with CRE Loaded or Zen Cart (especially if your osCom does not have Easy Populate, Sale Maker, Cross Sell, Specials, Featured Products, HTML editors, etc). However, if you have good content and want to sell Virtuemart is a great option for you.
The best open source system depends on what you want to do and how you want to do it.
I have listed features of Virtuemart, OSCommerce and CRE-loaded

If you have set your WordPress site to display post excerpts on the front or home page, you will want visitors to click on the title or a link to encourage them to continue reading your post or article, right? WordPress makes this technique easy, and customizable.
Here is the steps:
Go to wordpress admin panel –> Design tab –> Theme Editor.
Select Main Index template (index.php) to edit it
Find the line “<?php the_content(‘Read the rest of this entry »’); ?>”
And replace it with the following code.
<?php
$content = get_the_content($more_link_text, $stripteaser, $more_file);
if(strlen($content)>500) // chanage 500 as per your needs
{
$part_msg=substr($content, 0, 500);// chanage 500 as per your needs
echo ‘<p>’.$part_msg.’… ‘;
?>
<br /><br />
<a href=”<? comments_link(); ?>”>Read More…</a></div>
<?php
echo ‘</p>’;
}
else
{
echo ‘<p>’.$content.’</p></div>’;
}
?>
Where “500″ represents number of characters that you want to show.
If you cannot able to make the above changes with the wordpress theme editor, use your ftp.
