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.

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.

Example:

<?

$newImg = imagecreatetruecolor($nWidth, $nHeight);

imagealphablending($newImg, false);

imagesavealpha($newImg,true);

$transparent = imagecolorallocatealpha($newImg, 255, 255, 255, 127);

imagefilledrectangle($newImg, 0, 0, $nWidth, $nHeight, $transparent);

imagecopyresampled($newImg, $im, 0, 0, 0, 0, $nWidth, $nHeight, $imgInfo[0], $imgInfo[1]);

?>

Another way to fix this issue:

phpThumb() - Resize images on the fly

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.

Download: Download

Site: phpThumb()

Demo: Demo

Installation:

1. unzip the folder and upload the content into the server
2. give the correct path of the phpThumb.php and image path as per the following syntax

Resize Syntax:
<img src=”../phpThumb.php?src=images/watermark.png&bg=FFFFFF&f=png” alt=”">
<img src=”../phpThumb.php?src=images/watermark.png&bg=FFFFFF&f=gif” alt=”">
<img src=”../phpThumb.php?src=images/watermark.png&bg=FFFFFF&f=jpeg” alt=”">

where the bg=FFFFFF represents the bg color of your transparent image.

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.

Syntax: <?php the_author_description(); ?>

Example: <p>Cindy biography: <?php the_author_description(); ?></p>

the_author_login

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

Syntax: <?php the_author_login(); ?>

Example: <p>Author username: <?php the_author_login(); ?></p>

The_author_firstname, the_author_ lastname, the_author_ nickname

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.

Syntax: <?php the_author_firstname(); ?>, <?php the_author_nickname(); ?>, <?php the_author_lastname(); ?>

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.

Eg: <a href="mailto:<?php echo antispambot(get_the_author_email()); ?>">email

 author</a>

the_author_url

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.

Syntax: <?php the_author_url(); ?>

Example: <p>Author's web site:

<a href="<?php the_author_url(); ?>"><?php the_author_url(); ?></a></p>

the_author_aim

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.

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,

          'hide_empty' => true,

          'feed' => ,

          'feed_image' =>  ); ?>

By default, the usage shows:

    * Excludes users with no posts

<?php  wp_list_authors('show_fullname=1&optioncount=1'); ?>

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.
