10 useful htaccess tricks to improve your website

[caption id="attachment_632" align="alignleft" width="275"] useful htaccess tricks[/caption]

For some reason, the .htaccess file is often overlooked by web designers. If you have no idea what the .htaccess file is, I’ll just give you the Wikipedia definition: “A .htaccess (hypertext access) file is a directory-level configuration file supported by several web servers, that allows for decentralized management of web server configuration.”

But let’s get to it, here are some of the cool things you can do in your .htacces file.

1. Hotlinking protection with .htaccess

Websites that steal your written content can be quite annoying because they can hurt your Google rankings by creating duplicate content. However there is even worst: websites that steal your content AND don’t even make the effort of downloading images and reuploading it on their server. Loading images from your server is called hotlinking, and it’s a bad practice because it steals some of your precious bandwidth.

To preven people from hotlinking your images, just include the following lines in your htaccess file (obviously replace yoursite.com with your site’s URL.

RewriteBase /
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://(www.)?yoursite.com/.*$ [NC]
RewriteRule .(gif|jpg|swf|flv|png)$ /feed/ [R=302,L]

How To Completely Clean Your Hacked WordPress Installation

Getting hacked kills, plain and simple. It can affect your rankings, cause your readership to be exposed to virus and Trojan attacks, make you an unwilling promoter to subject material you may not actually endorse, and in many cases cause the loss of valuable content. However, once it happens it is usually best to not procrastinate on the clean up process, since a speedy restore will most times minimize the damage that was caused.

While almost all sources will recommend that you upgrade your WordPress to the latest version, what the majority neglect to tell you is that in most cases simply doing so will not prevent the attackers from getting back in, even if there are no known exploits with the latest version. The hackers may have left a back door file hidden in a directory where it wouldn’t get overwritten with an upgrade, or inserted code into your theme, or simply created an account that they then granted admin privileges to. Any one of those would allow them back in, even after you patched what was wrong the first time. Therefore I am providing this step by step process on how to completely clean out and restore a WordPress installation that has been hacked.

1. Backup the site and the database.

Even a hacked copy of your blog still probably contains valuable information and files. You don’t want to lose this data if something goes wrong with the cleanup process. Worst case scenario you can just restore things back to their hacked state and start over.

2. Make a copy of any uploaded files, such as images, that are referenced.

Images are generally exempt from posing a security risk, and ones that you uploaded yourself (as opposed to ones included with a theme, for instance) will be harder to track down and replace after things are fixed again. Therefore it is usually a good idea to grab a copy of all the images in your upload folder so as to avoid broken images in posts later. If you have any non-image files that could potentially have been compromised, such as zip files, plugins, or php scripts that you were offering people, then it is a good idea to grab fresh copies of those from the original source.

3. Download a fresh version of WP, all of the plugins you need, and a clean template.

Using the WordPress automatic upgrade plugin does make it easier to upgrade every time a new version comes out. However, it only replaces WordPress specific files, and does not delete obsolete ones. It also leaves your current themes and plugins in place, as is. This means that if used to upgrade a blog that has already been compromised, it can very well leave the attackers a way back in. It is best to start over from scratch as far as the files portion of your installation goes. Note that if you use the EasyWP WordPress Installer script that I wrote it saves you from having to download, unzip, and then upload all of the core WordPress files, although you will still need to grab fresh copies of the themes and plugins that you want to use.

Top 40 Website Programming Languages

Hi Friends, I thought it would be interesting to see if I could find out what programming languages the most popular websites use.

Obviously This is not easy to find out any websites or software tools, because the developers usually they don't want to publish their programming code to the people. So it is very tough task to figure out.

I got some information from other reference sources in searching and then i have made some list here..

This results are in no way definitive and may even be wrong, but the results are from HTTP Header information, Request for file types (.php for example), Searches on forums, presentations and Google Educated guesses ;)

It is purly the programming languages that are serving through HTML.

Results

-- Website -- Programming Language Used
-------------------------------------------------------------

Google - C, C++, PHP*, Ajax

facebook.com -- PHP

youtube.com -- Python

yahoo.com -- PHP*

Scroll to Top - using jQuery

Hi friends, Now we are going to look about how to using scroll to top(images) by using jQuery. If the website has lot of contents in a single page which is useful and easy for users to scroll up to the top page by using some smooth effects. Lets start our code.

First of all we create a image icon and fixed it in bottom right corner of the page.

First put the following html code in your footer area.

<a href="#" class="scrollup">Scroll</a>

Then we link up with the css.

.scrollup{

    width:40px;

    height:40px;

    opacity:0.3;

    position:fixed;

    bottom:50px;

    right:100px;

    display:none;

    text-indent:-9999px;

    background: url('icon_top.png') no-repeat;

}

You can see in the above css that we fixed icon at the bottom.

Now do some jquery functions on your head area of the html.

$(window).scroll(function(){

        if ($(this).scrollTop() > 100) {

            $('.scrollup').fadeIn();

        } else {

            $('.scrollup').fadeOut();

        }

    });

The next step is for scrolling to the top smoothly, if the button is clicked. We can do use the click function for that.

$('.scrollup').click(function(){

    $("html, body").animate({ scrollTop: 0 }, 600);

    return false;

    });

Thats is it, You can test this code in your localhost.

This is complete jQuery code :

<script type="text/javascript">

    $(document).ready(function(){

        $(window).scroll(function(){

            if ($(this).scrollTop() > 100) {

                $('.scrollup').fadeIn();

            } else {

                $('.scrollup').fadeOut();

            }

        });

        $('.scrollup').click(function(){

            $("html, body").animate({ scrollTop: 0 }, 600);

            return false;

        });

    });

</script>

Notes :

Don't forget to add the following code in your head tag or else it does not work.

<script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"></script>

How to Increase the Maximum File Upload Size in WordPress

[caption id="attachment_595" align="alignleft" width="300"] Increase the Maximum File Upload Size[/caption]

By default the WordPress gives the uploading limit around 2 mp size. This does not nowadays, because even a minute movie with HD takes much heavy size file. In this post, I will give you some tricks to increase the maximum file upload size in WordPress.

Step 1: Take your theme functions.php file

Just add the following code into that,

@ini_set( 'upload_max_size' , '64M' );
@ini_set( 'post_max_size', '64M');
@ini_set( 'max_execution_time', '300' );

Step 2: Create or Edit php.ini settings

In your root folder, create (If you do not have) a new file called php.ini, add the following code

upload_max_filesize = 64M
post_max_size = 64M
max_execution_time = 300

Step 3: Do some in .htaccess

add the following in your root .htaccess file

php_value upload_max_filesize 64M
php_value post_max_size 64M
php_value max_execution_time 300
php_value max_input_time 300

Notes:-

If you are in a shared hosting this techniques will not work, In that case you would have to contact your hosting provider to increase the size limit.

Setting Up Apache Server Virtual Host In Your Windows OS

For Coders, This Virtual Host option is flexible in project making. There is lot of 3rd party tools available in the market like Xampp, Wamp, but those are set to be in proper directories or else it wont work.

If you are a php developer and need to organized your website projects on certain folder with each individual host address e.g. "test1.web", "test2.web", you can use any name for virtual host but don't use ".com" extension as this will tell the browser to look the website on the internet and not on your local pc.

This procedure assume that you have already installed the apache for windows, php module for apache

Step -1 :-

open the apache configuration file, note that better to install the apache on the root of drive C:

(c:/apache/) to make it compatible for short naming folder, ok so assume your apache was installed on the root drive c:

so open the configuration file on c:/apache/conf/httpd.conf and enable the virtual host module, scroll down to near end of configuration and you will find this

# Virtual hosts
# Include conf/extra/httpd-vhosts.conf

uncomment the vhost module by removing the hash character on fron of it so it will look like this

# Virtual hosts
Include conf/extra/httpd-vhosts.conf

ok save the file.

PHP Tutorials for beginners – Variables

Hi Friends, Hope you are doing well. I believe that you have gone through our previous PHP tutorials and get some ideas. That is fine. Today we are going to talk about PHP Variables.

PHP variables as containers for storing data.

Rules for PHP variables:

• A variable starts with the $ sign, followed by the name of the variable.


• A variable name must begin with a letter or the underscore character.


• A variable name can only contain alpha-numeric characters and underscores (A-z, 0-9, and _ ).


• A variable name should not contain spaces.


• Variable names are case sensitive ($y and $Y are two different variables).

OK. Do not get sleepy, If you go for example you can easily understand what is variable.

For eg 1:

<?php
     $a = "Hello, ";
     echo $a;
?>

Check this output in your localhost, it will show Hello. 

This is it, Here $a is a variable, which contains hello value into that. Like that way we have to use php variables.

Eg 2:

<?php
       $v = 2500;
       $x = 7500;
       $y = 5000;
       $z = $v+$x+$y;
       echo $z;
?>

Do this practice in your localhost. Now you can get clear view about these variables.

Notes:

We do not initiate data type in PHP variables. It automatically converts the variable to the correct data type, depending on its value.

If you use alphabets, make double codes (in between that). for example ( $name = "hello word, how are you"; ) and should end with semi colon.

PHP has four different variable scopes. We will see about those in next tuto's.

Like that way we are going to develop.

PHP codes must start with <? and ends with ?>. In between these we should put our code.
