Problem with transparent image resizing? – PHP
Dec 3rd
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.
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.

- 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.
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.

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,

Problem with WordPress admin-login? or Forgot your WordPress admin password?
Sep 23rd
Reset your local wordpress password easily
While building my theme I installed wordpress with lots of sample data and I realized.
mysql picture
I forgot my password and couldn’t recover it even with a “forgot password” link. So after
playing around for 30 mins, I reset my password. This is how.
WordPress admin login error happen for two following reason:
- User may forgot the admin password
- User might have entered wrong site url in setting tab
go to your mysql administrator (usually called as phpmyadmin)
- select your wordpress database
- run the following update query with your password as in bracket using sql tab
SELECT ‘wordpress’ //this should be your database name
UPDATE `wp_users` SET `user_pass` = MD5( ‘password’ ) WHERE `ID` =1 LIMIT 1 ;
where password is your new password. Your password is reset, for the admin acount.
For admin side login problem, there might be another reason. You might have given wrong site
url. This can be update by the following query
UPDATE `wp_options` SET `option_value` = ‘You site url’ WHERE `wp_options`.`option_id` =1
LIMIT 1 ;
It will update your site url in the wp_options table and it will solve your login error.
