As a Web Developer or Web Designer, it is important that website’s we develop are working on all major browsers, or on all(old or new) browsers if possible. but some browsers (specially the old one’s) has their own specific way of translating or handling css /style directions.

And also sometimes we need to show or hide some specific elements for some browsers or browser versions.

for situations like the above, stylesheet separation for specific browsers can help.  look at the codes below.

<?php
if(strstr($_SERVER['HTTP_USER_AGENT'], "MSIE 6")){
?>
<link rel="stylesheet" type="text/css" href="/css/ie6.css" />
<?php
} elseif(strstr($_SERVER['HTTP_USER_AGENT'], "MSIE 7")) {
?>
<link rel="stylesheet" type="text/css" href="/css/ie7.css" />
<?php
} elseif(strstr($_SERVER['HTTP_USER_AGENT'], "MSIE 8")) {
?>
<link rel="stylesheet" type="text/css" href="/css/ie8.css" />
<?php
} elseif(strstr($_SERVER['HTTP_USER_AGENT'], "Firefox")) {
?>
<link rel="stylesheet" type="text/css" href="/css/ff.css" />
<?php
} elseif(strstr($_SERVER['HTTP_USER_AGENT'], "Chrome")){
?>
<link rel="stylesheet" type="text/css" href="/css/chr.css" />
<?php
} elseif(strstr($_SERVER['HTTP_USER_AGENT'], "Safari")){
?>
<link rel="stylesheet" type="text/css" href="/css/saf.css" />
<?php
}
?>

what this codes do is detect the users browser then prints the specific stylesheet for that browser. you can put this code directly below your main CSS stylesheet, because the primary use of this code is to override the main CSS settings. so for example a div is showing differently in IE6 browser, you can just include the style direction of this div into the ie6.css, so when a user browse your website using IE6 browser, the main CSS setting for this div will be override by ie6.css.

the code above can also be used on a wordpress blog or wordpress based sites, you just need to add your wordpress site’s template url to the CSS path. please look at the code below.

<?php
if(strstr($_SERVER['HTTP_USER_AGENT'], "MSIE 6")){
?>
<link rel="stylesheet" type="text/css" href="<?php bloginfo('template_url'); ?>/css/ie6.css" />
<?php
} elseif(strstr($_SERVER['HTTP_USER_AGENT'], "MSIE 7")) {
?>
<link rel="stylesheet" type="text/css" href="<?php bloginfo('template_url'); ?>/css/ie7.css" />
<?php
} elseif(strstr($_SERVER['HTTP_USER_AGENT'], "MSIE 8")) {
?>
<link rel="stylesheet" type="text/css" href="<?php bloginfo('template_url'); ?>/css/ie8.css" />
<?php
} elseif(strstr($_SERVER['HTTP_USER_AGENT'], "Firefox")) {
?>
<link rel="stylesheet" type="text/css" href="<?php bloginfo('template_url'); ?>/css/ff.css" />
<?php
} elseif(strstr($_SERVER['HTTP_USER_AGENT'], "Chrome")){
?>
<link rel="stylesheet" type="text/css" href="<?php bloginfo('template_url'); ?>/css/chr.css" />
<?php
} elseif(strstr($_SERVER['HTTP_USER_AGENT'], "Safari")){
?>
<link rel="stylesheet" type="text/css" href="<?php bloginfo('template_url'); ?>/css/saf.css" />
<?php
}
?>

You can insert this code into your wordpress theme’s header file (header.php), directly below the main CSS declaration:

<link rel="stylesheet" href="<?php bloginfo('stylesheet_url'); ?>" type="text/css" media="screen" />

well today I’ll share some ways on how to Search and Replace datas or texts in WordPress. this will be useful when you are transferring a wordpress blog from one domain to another or if you’ve developed a wordpress site on your localhost and you’re gonna upload it to an online server or on your own domain, of course you need to update the paths on your posts.

for example you’ve developed a wordpress site on your local machine and you installed it on http://localhost/wordpress, when you transfer the site into a live server, you need to change that path in your database for wordpress to display your blog posts or menu links correctly, and not only that – there may be times that you hardcoded a link (eg. images,post) in your blog post. i dont know for you, but for me updating it one by one is a no no.. i mean why are you gonna do it manually, when you can do it automatically? right? right? or left? haha..

Here are some other ways or situations on when you can use the search and replace function.

1. Correcting a typographical Error – you discovered that one of the words you frequently use was mispelled, for example instead of typing a bacon, you are typing in and using the word vacon with a “V” all the time (haha..)

2. Updating a Name/Word - you want to change word1 to word2, or name1 to name2

3. Deleting Weird Characters - you are copying and pasting articles from one site or documents and you didn’t noticed that some special characters are also copied eg. Â, ♠ , ¶ ,Æ and so on..

Here are some methods that you can do to search and replace texts in wordpress database or blog posts.

1. using MySQL search and replace function within PHPMYADMIN

open your wordpress database using phpmyadmin, click the SQL tab and enter the following codes:

UPDATE wp_posts SET post_content = REPLACE (
post_content,
'OLD TEXT',
'NEW TEXT');

the code above uses the MySQL replace function to first search the OLD TEXT in the wp_posts table then post_content field, and when found replace it with the NEW TEXT.

you can search and replace datas from any tables/table fields in the database. you can also use this method on any applications that uses mysql as a database.

2. using WordPress Search and Replace Plugin

same functionality as the mysql replace function, the only difference is this plugin provides a user interface within the wordpress admin panel. you can download the plugin here. http://wordpress.org/extend/plugins/search-and-replace/

NOTE: Don’t forget to create a back up of your database first before trying any of the methods above. ok? it’s better to be sure, right?

Enjoy! please share.

WHAT DO YOU NEED…

1. A Web Server - Apache / IIS will work too..
   
2. PHP - so that our web server can understand our php file.
   
3. Database - MySQL
4. Text Editor - Notepad, Dreamweaver, PHP Designer or any text editor that you want..
5. Web Browser - you can use any broswer of your choice(Firefox, IE, SAFARI, OPERA, Chrome)..
6. Operating System - Linux, Windows or Mac OS.
   

In this tutorial you may use any of the following:

LAMP stands for Linux, Apache, MysQL, PHP

WAMP stands for Windows, Apache, MysQL, PHP

MAMP stands for Mac, Apache, MysQL, PHP

XAMPP stands for Any OS, Apache, MysQL, PHP, Perl

choose any of the above mentioned depending on the operating system you’re using, this is includes all the source code, binaries, folders etc.. in just one installation!

DOWNLOAD LINK…

download the latest stable package..

XAMPP – http://www.apachefriends.org/en/

WAMP – http://www.wampserver.com/en/

MAMP – http://www.mamp.info/en/download.html

for linux users you may just download xampp..

After downloading Install it and now you’re good to go…

* for windows user, open your favorite browser then type http://localhost on the address bar

* for mac users do the same thing but put ~youruserdirectory after http://localhost, so if your userdirectory on mac is daniel, you need to type http://localhost/~daniel

WHAT IS PHP?

• It is a server-side, scripting language. - it does’nt need a compiler to run or it does’nt need to be compiled. Another example of scripting language is Javascript. but unlike Javascript, PHP runs on the web server. Javasript runs on the users browser.

• PHP’s syntax is very similar to C, Perl and Java.
• It is an HTML embedded scripting language. - it is used to output html in the browser. you need to change the extension file of your html to .php to tell the server process it as php.
• It can make your page more dynamic.

WHY USE PHP?

• It is open source - it is free to download and free to use.

• It is cross platform - it can run on windows, mac or linux server, and all browsers.

• Most opensource web applications are powered by PHP - WordPress, Joomla, Mambo, PhpBB, etc. by learning php you may be able to work with these and also customize it.

• Almost 20Million webpages in the world uses PHP - just like google, friendster, multiply, facebook, etc..

• It is powerful, robust and scalable - it can deliver excellent performance even if your site is a high traffic site.

• it has built in database support -you can create database driven web applications immediately.

• Anything you can do with a regular programming laguages, you can do with PHP - you can perform calculations, validate user inputs, process forms, read and write files etc…
