  $user_field = variable_get('brightcove_user_field', '');
  // Set our search terms
  $terms = array(
    'all' => $user_field .':'. $user->name

How to use brightcove video Search in drupal

2013-01-30T23:41:00.001+05:30

Brightcove video cloud, a cloud based video hosting and publishing solution. Drupal is one of the most commonly used open source CMS.

To integrates brightcove video cloud into drupal, drupal community provides one module called Brightcove module. . Using this module you can add Brightcove video to your content and access the information from the Video Cloud in your site.

In brightcove module they are using Brightcove Media API and this APi provides various methods to retrieve properties from brightcove video cloud. But this module is mainly focusing on find method. So here I am trying to explain how to use search method in drupal. Search method is also a simple function to retrieve properties and information from Brightcove.

To call search method we need to pass three arguments - method, terms and params

.Using this method we can search custom fields from brightcove. Here I'm explaining how to search custom fields value from brightcove using search method.

Below code shows how to search for a video with "jobs" in the title AND tags.

// Define our parameters
$params = array(
    'video_fields' => 'id,name,shortDescription'
);

// Set our search terms
$terms = array(
    'all' => 'display_name:jobs,tag:jobs'
);

// Make our API call
$videos = $bc->search('video', $terms, $params);

Below code will explain how to search video with custom fields.
custom field name is drupal_user and this field is used for storing uploaded user name(Drupal Username) in brightcove.

// Define our parameters
$params = array(
    'video_fields' => 'id,name,shortDescription'
);

// Set our search terms
$terms = array(
    'all' => 'drupal_user:jobs'
);

// Make our API call
$videos = $bc->search('video', $terms, $params);

How to create Virtual Hosts in Ubuntu

2012-10-05T17:53:00.001+05:30

Virtual Hosting is a method for hosting multiple sites/domains in a single server. It helps to reduce the cost and can share the memory and processor cycle. In local host also we can create Virtual host and we can call original domain name(production/live domain) from our development environment(localhost). Here I am providing the steps for creating Virtual host in Linux/Ubuntu workstation.

i. Assume your code resides at /var/www/yoursite

ii. You can access your site using http://localhost/yoursite.

iii. Edit vhosts file in sites-enabled. sudo gedit /etc/apache2/sites-enabled/vhosts.conf.

iv. Add below code in vhosts file

ServerName local.yoursite.com

ServerAlias www.local.yoursite.com

DocumentRoot /var/www/yoursite

</VirtualHost>

v. Open the file /etc/hosts in your editor.

vi. Add below lines of code.

127.0.0.1 local.yoursite.com

vii. Restart your apache server.

sudo /etc/init.d/apache2 restart

viii. Access http://local.yoursite.com to view your site in direct domain.

How to convert milliseconds to date format in PHP

2012-09-01T00:15:00.002+05:30

Normally date field is stored in database as timestamps format, the number of seconds since 00:00:00 UTC on January 1, 1970. Some times the date represented as the number of milliseconds.

There is no default function available in PHP to convert this milliseconds representation to human readable format. In PHP date function is used for converting timestamp format to local date/time format.

This following PHP function will convert milliseconds format to local date format

$milliseconds = 1340562600000;
$timestamp = $milliseconds/1000;
echo date("d-m-Y", $timestamp);

output = 25-06-2012

Redirect all users to access the site with 'www' prefix using htaccess file

2012-07-13T01:34:00.002+05:30

We can redirect the site url to "www" prefix, whether the user is accessing the site without "www" prefix by adding rewrite url in .htaccess file in root folder.

add following lines in .htaccess file to add www prefix.

 RewriteEngine on

 RewriteCond %{HTTP_HOST} ^yoursitename\.com$ [NC]

 RewriteRule ^(.*)$ http://www.yoursitename.com/$1 [L,R=301]

CSS fix for Chrome IE7 and IE8

2012-04-12T14:30:00.002+05:30

In some cases we need to add browser specific css properties for the site, like separate css for IE 7 and IE8 to acheive the correct layout. To acheive that we can use different methods - 1. add custome CSS file for each browser and 2. Add custom properties in the main CSS

Here I am specifying how to add separeate css properies for Chrome, IE 7 & IE8 in the main CSS file.

Chrome

Google Chome is the fast growing web browser. Some times the site layout will break and need to alter css property for this particular browser.
To fix CSS issues for Chrome use body:nth-of-type(1) .elementOrClassName{property:value;}.
Eg: body:nth-of-type(1) .sitename{margin:20px;}
HTML
<div class="sitename"></div>

IE8

For IE8 use inline css hack "\0/".
.elementOrClassName{property:value;\0/}
Eg: .sitename{margin:20px;\0/}

IE7

* (star) can be used as the inline hack for ie7
.elementOrClassName{*property:value;}
Eg: .sitename{*margin:20px;}

IE6

_ (underscore) can be using for ie6
.elementOrClassName{_property:value;}
Eg: .sitename{_margin:20px;}

Top 20 Wordpress plugins and their Drupal equivalent

2011-10-15T21:21:00.002+05:30

Wordpress is a popular blogging platform like google blogger. It provides more flexibility than blogger. If you want setup a good looking blog site quickly without knowing more technical stuff, then Wordpress should be the most likely choice for you . It provides a lot of plugins that just enable to activate more user friendly functionalities.

Wordpress is a Content Management System(CMS) build around PHP and MySQL. Like Wordpress, Drupal is also a CMS build around PHP and MySQL with almost all the strengths of Wordpress. But Drupal is more developer centric and customizable and robust when compared to Wordpress and it useful for developing Medium and large Websites, other than just a blog site.

Due to the huge fanbase and ease of programming, Wordpress has numerous plugins at its disposal. There are Drupal equivalents for most of these. Here is our take on a few popular Wordpress plugins and their equivalent Drupal modules.

1. Akismet - It is a Wordpress plugin that check your comments against the Akismet web service to see if they look like spam or not and lets you review the spam it catches under your blog's "Comments" admin screen.

Mollom is the Drupal equivalent of Akismet and is a popular spam prevention service module. Drupal version of Akismet module also available

2. All in one SEO pack - Automatically optimizes your WordPress blog for Search Engines (Search Engine Optimization)

Drupal has several tested and proven modules available in the Drupal core as well as in the contributed section. The most popular ones are

Path – core module

Search 404
Page title
Nodewords ( A new module Metatagsis on development to replace nodewords. Currently there is a quick solution to use Metatags Quick available for Drupal

3. Bad Behavior - It prevents spammers from ever delivering their junk, and in many cases, from ever reading your Wordpress site in the first place.

Bad Behavior is available for Drupal and it is a set of PHP scripts which prevents spambots from accessing your site by analyzing their actual HTTP requests and comparing them to profiles from known spambots. It goes far beyond User-Agent and Referer, however.

4. Broken Line Checker - It will check your posts, comments and other content for broken links and missing images, and notify you if any are found.

Link Checker is the Drupal module to detect broken hypertext links.

5. Contact Form 7 - Wordpress plugin that can manage multiple contact forms, plus you can customize the form and the mail contents flexibly with simple markup. The form supports Ajax-powered submitting, CAPTCHA, Akismet spam filtering and so on.

Drupal has core module Contact, for Simple contact us form. Webform can be used to create any type of custom forms. It supports csv export of the collected information. It is also possible to use captcha with webforms.

6. Google Analytics for Wordpress - WordPress plugin allows you to track your blog easily and with lots of metadata.

The Google Analytics module for Drupal incorporates all the features of the Wordpress plugin for Drupal.

7. Google XML sitemaps for Worpress - This plugin will generate a special XML sitemap which will help search engines to better index your blog.

Drupal has also a Google XML Sitemap module with the same functionality.

8. GTranslate is a Wordpress plugin that provides an automatic translation service to translate your web page with Google power. With the ability to translate over 58 available languages your site will be available to more than 98% of Internet users.

GTranslate for Drupal does the same thing in Drupal and has been coded by the same author.

9. Lightbox Plus is a Wordpress plugin that permits users to view larger versions of images, simple slide shows, videos and content all in an overlay. It uses the popular colorbox jquery plugin.

Colorbox module for Drupal will provide full integration of the colorbox plugin.

10. MapPress is is the most popular and easiest way to create great-looking Google Maps and driving directions in your Wordpress blog.

In Drupal Gmap is the advanced and complete google map solution in Drupal. If you just want a basic google map embedded in a page, use LocationMap or Simplemap as per your requirements.

11. Newsletter is a Wordpress plug-in that lets you collect subscribers on your blog with a single or double opt-in subscription process. Double opt-in is law compliant and it means the user has to confirm the subscription following simple standard instructions sent to him via email.

Simplenews Drupal module - It can be used to send newsletters. Both anonymous and authenticated users can opt-in to different mailing lists. HTML email can be send by adding the Mime Mail module.

12. NextGEN Gallery Wordpress plugin is a fully integrated Image Gallery plugin for WordPress with a slideshow option. Before I started writing the plugin I studied all the existing image and gallery plugins for WordPress. Some of them are really good and well designed, but the gap I filled was a simple administration system at the back end which can also handle multiple galleries.

There are no equivalent ready made solutions available for Drupal, though there are some modules like Fast Gallery available, it will not stand anywhere near the features provided by the nextgen gallery.

The best way to create a custom image gallery in Drupal is to use the content types, image field and views. You can use modules like DDBlock, Views_Slideshow using views and content types.

13. Redirection is a WordPress plugin to manage 301 redirections and keep track of 404 errors without requiring knowledge of Apache .htaccess files.

Path redirect is the popular alternative in Drupal

14. Simple Tags add some tools for taxonomies like Terms suggestion, Mass Edit Terms, Auto link Terms, Ajax Autocompletion, Click Terms, Auto terms, Advanced manage term

In Drupal: By default Drupal taxonomies support tags with auto-complete option. Other features like tagcloud and manage tags can be done using the

Tagadalic For tagclouds
Taxonomy Manager - Manage taxonomies
Community tags - allow users to tag content and track it.

15. Social Plugins - Wordpress comes with the popular social plugins Addtoany and Addthis.

Both of these plugins provide share icons of the popular social bookmarking websites. Add-to-any allows integration with google analytics and Addthis allows customization of the social icons.

Both Addtoany and Addthis are available as modules for installation in Drupal to enhance your social experience while using Drupal

16. WP e-Commerce is a free WordPress Shopping Cart Plugin that lets customers buy your products, services and digital downloads online.

Ubercart is the popular tool for ecommerce applications in Drupal. It is a superior e-commerce solution available when compared to the wordpress equivalent and has tons of features.

17. WP-DB-Backup is a Wordpress plugin that allows you easily to backup your core WordPress database tables. You may also backup other tables in the same database.

In Drupal the Backup and Migrate module (is the best automated backup solution integrated with Drupal.)

18. WP Security Scan is a Wordpress plugin that scans your WordPress installation for any security vulnerabilities.

Security review is the Drupal module that offers the same functionality will do the same kind of security check for Drupal.

19. WP-Super Cache is a Wordpress plugin that generates static html files from your dynamic WordPress blog. After a html file is generated your webserver will serve that file instead of processing the comparatively heavier and more expensive WordPress PHP scripts.

Boost is the popular alternative in Drupal for static page caching

20. Yet Another Related Posts Plugin (YARPP) gives you a list of posts and/or pages related to the current entry, introducing the reader to other relevant content on your site.

2011-08-27T18:22:00.001+05:30

The RabbitVCS is a set of graphical tools written to provide simple and straightforward access to the version control system(VCS). This is similar to Tortoise SVN for Windows.

It provide multiple clients and extensions to give you a uniform experience no matter what development tools you use. It provide all Subversion client functionality without touching the command line so it is very useful for developers who are not familiar with Linux commands and newbies to Linux.

It also provide an easy to use command line tool in this package.

To install RabbitVCS in Ubuntu, first we need to add the PPA

Karmic and later

sudo add-apt-repository ppa:rabbitvcs/ppa

Hardy, Intrepid and Jaunty

Add the following line to your /etc/apt/sources.list file (signing key = 1024R/34EF4A35)

deb http://ppa.launchpad.net/rabbitvcs/ppa/ubuntu **DISTRIBUTION** main

Update your software package repositories with:

sudo apt-get update

Install :

sudo apt-get install rabbitvcs-core rabbitvcs-nautilus rabbitvcs-thunar rabbitvcs-gedit rabbitvcs-cli

From Tarball

Installing from our distributed tarball is relatively straightforward on Ubuntu. First, make sure you install all dependencies:

sudo apt-get install python-nautilus python-configobj python-gtk2 python-glade2 python-svn python-dbus python-dulwich subversion meld

Then download the tarball and from the top folder type:

sudo python setup.py install

Once that is done working, look in the clients folder and read the README file for each client/plugin to learn how they are installed.

Regular expression for validating US phone number

2011-06-30T11:36:00.001+05:30

US phone number format validation using regular expression.

The common US phone number format is 3digits-3digits-4digits
eg: 222-333-3333
      111-222-1234
The regular expression for validating this format is

function usphone($string) {
   if(preg_match('/^[0-9]{3}\-[0-9]{3}\-[0-9]{4}$/', $string)) {
    return true;
}
else{
    return false;
}
}

Validation using Javascript

function isUSphone(phoneno) {
   var filter = /^[0-9]{3}\-[0-9]{3}\-[0-9]{4}$/;
   if (filter.test(phoneno))
        returntrue;
    else
        return false;
}

In Jquery

if($("#phone-num").val().match(/^[0-9]{3}\-[0-9]{3}\-[0-9]{4}$/)) {
//valid phone number
}
else {
//not a valid number
}

*phone-num - id of phone number field(input field)

WinSCP alternative in Ubuntu.

2011-05-06T00:27:00.000+05:30

WinSCP is the most popular file transfer application in Windows Operating systems like filezilla. It helps to copy files from remote system to local system and wise versa. In Linux, filezilla is use for this purpose. But we can simulate WinSCP in Linux/Ubuntu by using Nautilus.

To simulate this we need to install Nautilus elementary, which is a nice addition to Nautilus to enable split view in the file browser. The steps for installing Nautilus elementary in Ubuntu are here.

Type the following in console

sudo add-apt-repository ppa:am-monkeyd/nautilus-elementary-ppa

The above line will add the repository from where you can download the Nautilus elementary

sudo apt-get update && sudo apt-get upgrade

will update the local repositories and update all the software.

nautilus -q

Now open Nautilus and press F3. You should able to see the split windows.

Access Remote system

Access the remote system by connecting to remote system in one pane. Select the right side pane and go to File->Connect to Server

Fill up the details of the remote system and then press connect. Now the right hand panel will have the files of remote system.

The left hand panel will have the files of local system. To drag and drop the files form one pane to other for copying the files. Also you can use SSH, FTP, SFTP etc protocols to connect the remote system.

Drupal 8 developement begins

2011-03-11T15:50:00.001+05:30

After the release of drupal 7 in earlier this year, drupal developers beginning to plan for new version, Drupoal 8. In annual DrupalCon conference this week, Drupal founder Dries Buytaert detailed what lessons were learned in the Drupal 7 development process and how those lessons will be applied to Drupal 8.

Drupal is among the most popular open source content management system in use. Thousands of websites uses drupal. Major sites like Mozilla, NASA, Whitehouse.gov and among others used drupal for their sites.
Development is now beginning on Drupal 8 and Buytaert is restructuring the project to ensure that the lessons of Drupal 7 are not forgotten. Dealing with bugs is one of Buytaert's top priorities.
"At no point in time will there be more than 15 critical bugs," Buytaert said. "I will not pull in a big change if we know there are known bugs. This gives us the ability to do timely releases because we know at most the release is only 15 critical bugs away from being ready."
"The biggest risk to Drupal is getting so big that we become slow," Buytaert said. "Our ability to be open to change, accept change and be agile is key."

-i, --interactive	prompt before overwrite (overrides a previous -n option)
-H	prompt before overwrite (overrides a previous -n option)
-l, --link	link files instead of copying
-L, --dereference	always follow symbolic links

scp copies files between hosts on a network. It uses ssh(1) for data transfer, and uses the same authentication and provides the same security as ssh(1). Unlike rcp(1), scp will ask for passwords or passphrases if they are needed for authentication.
File names may contain a user and host specification to indicate that the file is to be copied to/from that host. Local file names can be made explicit using absolute or relative pathnames to avoid scp treating file names containing ‘:’ as host specifiers. Copies between two remote hosts are also permitted.

Syntax
scp [options] [[user@]host1:]file1[[user@]host2:]file2
Options

-1	Forces scp to use protocol 1.
-2	Forces scp to use protocol 2.
-4	Forces scp to use IPv4 addresses only.

-B	Selects batch mode (prevents asking for passwords or passphrases).
-C	Selects batch mode (prevents asking for passwords or passphrases).
-F ssh_config	Selects batch mode (prevents asking for passwords or passphrases).
-p	Preserves modification times, access times, and modes from the original file.
-q	Quiet mode: disables the progress meter as well as warning and diagnostic messages from ssh(1).
-r	Recursively copy entire directories. Note that scp follows symbolic links encountered in the tree traversal.
-v	Verbose mode. Causes scp and ssh(1) to print debugging messages about their progress. This is helpful in debugging connection, authentication, and configuration problems.

SSH

ssh - OpenSSH SSH client (remote login program)
ssh (SSH client) is a program for logging into a remote machine and for executing commands on a remote machine. It is intended to replace rlogin and rsh, and provide secure encrypted communications between two untrusted hosts over an insecure network. X11 connections and arbitrary TCP ports can also be forwarded over the secure channel.

Syntax
ssh [user@]hostname [command]

Move - mv

mv - move (rename) files
Rename SOURCE to DEST, or move SOURCE(s) to DIRECTORY.
Mandatory arguments to long options are mandatory for short options too.
Syntax
mv [options] [-T] SOURCE DEST
mv [options] SOURCE DIRECTORY

Options

--backup[=CONTROL]	make a backup of each existing destination file
-f, --force	do not prompt before overwriting
-T, --no-target-directory	treat DEST as a normal file
-v, --verbose	explain what is being done

Remove - rm
rm - remove files or directories

Syntax
rm [options] FILE
Options

-f, --force	ignore nonexistent files, never prompt
-i	prompt before every removal
-I	prompt once before removing more than three files, or when removing recursively. Less intrusive than -i, while still giving protection against most mistakes
--interactive[=WHEN]	prompt according to WHEN: never, once(-I), or always(-i). Without WHEN, prompt always
-r, -R, --recursive	remove directories and their contents recursively
-v, --verbose	explain what is being done
--version	output version information and exit

Install Drupal 6 in AwardSpace

2011-02-27T13:38:00.002+05:30

AwardSpace is a web hosting provider, to provide both free and paid services. In free hosting service a lot of people facing issues in drupal-6 installation. So they are switching the free hosting account to paid or switching drupal to other frameworks. So here I am trying explaining how to install drupal CMS in Awardspace web hosting server. Drupal 6 needs PHP5 for the installation.

For installing drupal, first download the installation files from Drupal site (drupal 6.20).Once you have downloaded Drupal and created an account in Awardspace, we need to upload the files to our Awardspace account. The easiest way to do this is using and FTP client, filezilla or other FTP client. Now you can install drupal. But before starting please check the PHP version that installed in your server. For checking go to PHP settings on the Web Manager of the Awardspace Control Panel, Make sure the PHP installed is PHP5 otherwise change the version to PHP5 (Some times they provide PHP4. If you have PHP4 then change it to PHP5). Otherwise this error might appear:

register_globals is enabled. Drupal requires this configuration directive to be disabled. Your site may not be secure when register_globals is enabled. The PHP manual has instructions for how to change configuration settings. (Currently using PHP register globals Enabled ('1'))

After changing PHP version, access your site through the browser. You will get a installation page on your browser. But some times it will throw an "500 Internal Server Error" but don't worry. To fix this, connect to your file manager from the Hosting Control Panel (or using your FTP client) and rename the .htaccess file in the drupal root directory to another name eg: .htaccess.old.

Then try again the install.php script, the page will let us access the install page. The first page is the Choose language screen where you can choose whether to install Drupal in English or another language.

You can install Drupal 7 also with the same steps.

Skinning Select box using Jquery

2011-02-26T17:26:00.002+05:30

A lot of jquery plugins are available in Internet to skin SELECT box. Some of them are very good but some times these plugins cause the performance of the site, if you are including lot of third party javascript files into your sites. I used some third party skinning javascript in my sites and it works fine but when I use lightbox and some other slide show plugin to my site this skinning js not working properly, because it took too much time to load all js.

So I planned to write a simple jquery code to skin the select box. I share the code here
<script>
$(document).ready(function(){
$("#Selectboxid").before("<

span class='selectboxspan'>Select One</span>");

    //On Change Event
    $("#Selectboxid").change(function(){
        $(".selectboxspan").html($("#Selectboxid option:selected").html());
    });
});
</script>

Also add these CSS in the code

select#selectboxid{width:61px;height:20px;opacity:0;filter:alpha(opacity=0);position:relative;z-index:5;}
span.selectboxspan{background:url(skin.png) no-repeat scroll 0 0 transparent; height:17px;overflow:hidden;padding-left:4px;position:absolute;width:63px; border:1px solid #cccccc;}

The HTML code
<select id="Selectboxid" name="skinnedSelectbox">
        <option value="0">Select One</option>
        <option value="1">Test1</option>
        <option value="2">Test2</option>
        <option value="3">Test3</option>
    </select>

Installing Apache, MySQL and PHP in Linux-Ubuntu

2011-02-20T17:34:00.009+05:30

Apache is the most commonly used web server. It is a free open source web server. PHP is an open source server scripting language. It has a lot of advantages. MySQL is also an open source database used for small and medium data storage. It can also used for large data storage also.

We can install apache, PHP and MySQL in two ways. 1. Download source code from their site and install. 2 the easiest way install it from synaptic package manager. If you use this method apt-get automatically manage all dependencies. So I explain the second method here.

1. Open the Terminal from Applications -> Accessories -> Terminal

2. Install apache2 copy paste command to terminal

sudo apt-get install apache2

3. Install PHP5

sudo apt-get install php5 libapache2-mod-php5

4. Restart apache

sudo /etc/init.d/apache2 restart

Now the PHP was installed. To test it create a php page in /var/www/ - the webroot and run it
Example sudo gedit /var/www/hello.php
write a basic php code in it

to run this script type http://localhost/hello.php in your browser and you can see "Hello World" in it.

5. Install mySQL

sudo apt-get install mysql-client mysql-server mysql-query-browser mysql-admin mysql-navigator php5-mysql php5-gd

6. Restart apache

sudo /etc/init.d/apache2 restart

7. If you need phpmyadmin follow this step. If you like to use MySQL GUI then skip this step

sudo apt-get install phpmyadmin

Restart apache

sudo /etc/init.d/apache2 restart

Add following lines in httpd.conf

# Enable PHPMyAdmin
Include /etc/phpmyadmin/apache.conf

To access httpd.conf copy paste following line to terminal

sudo gedit /etc/apache2/httpd.conf

Restart apache
8. If you need to access your url as http://localhost/~username, enable userdir module in apache2. enable mod_rewrite to allow clean url

cd /etc/apache2/mods-enabled
sudo ln -s ../mods-available/userdir.load
sudo ln -s ../mods-available/userdir.conf
sudo ln -s ../mods-available/rewrite.load
sudo /etc/init.d/apache2 reload

9. Create folder /home/<username>/public_html -- > this is the folder which we are going to use as the document root for local development. So you will be accessing your local websites as http://localhost/~username/sitename

10. Edit /etc/apache2/mods-available/userdir.conf and change the AllowOverride line to just read AllowOverride All
Now you can use public_html as user document root

Enjoy scripting
