107. What is a sub theme in Drupal ?

Sub-themes are just like any other theme, with one difference: They inherit the parent theme's resources. There are no limits on the chaining capabilities connecting sub-themes to their parents. A sub-theme can be a child of another sub-theme, and it can be branched and organized however you see fit. This is what gives sub-themes great potential.

Drupal Job Interview Questions and Answers ( a set of 50 questions, q52-q101)

101. What hardware does Drupal.org run on?

People often wonder what kind of hardware drupal.org runs on. Throughout the project history this has been a tough question. For a while it was a server in a random office building. That server eventually died and required a fund-raising effort to replace (the funds were raised in 24 hours!).

The critical infrastructure is all configured to share the load and be redundant. For example, db1 and db2 are configured to be master-slave most of the time to provide for better performance and allow the slave to be promoted to master if the master fails.

100. Drupal and Working with JavaScript

Drupal provides methods for implementing JavaScript. Using these methods will help to keep your code clean and to ensure compatibility with the way other modules implement JavaScript.

A couple of simple principles guide Drupal's JavaScript approach:

· All pages should be perfectly functional without scripts. JavaScript provides alternatives or supplements - not replacements - for standard elements.

No JavaScript is hard-coded into pages. Rather, actions are attached dynamically to page elements--and only if the needed JavaScript support is present.

99. Why does Drupal need a database? What databases are supported?

Drupal stores its information - the individual pages, the registered users, and so on - in the database. The database forms the back-end for your Drupal site. At this time, Drupal supports MySQL (or an equivalent such as MariaDB), PostgreSQL, and in Drupal 7, SQLite.

25. How to post videos from mobile to Drupal website ?

Posting video from mobile phone to drupal website via email requests from user to configure a mobile phone with smtp settings and reasonable Internet connection (3g). Costs depends from your mobile phone provider: at some networks you pay only for transfer volume, at others you might pay for "event" of establishing connection.
On server side you will probably need to setup smtp server and provide access to it to users of your website. Transcoding of posted video employs ffmpeg, its standard software on proper hosting server.
Process Overview
1. Email with video attachment from mobile phone is sent to a defined mailbox
2. Drupal website downloads Mail on cron (mailhandler module)
3. Emails are turned into nodes with videos as attachments
4. Media Mover runs on cron, trans-coding mobile video formats and creating thumbnails
5. Transcoded flash video files are added to cck file field
6. Thumbnail added to file field
7. Nodes are themed using swftools to display video using "JWplayer"
Modules used
• Mailhandler
• Mailssave
• Mediamover
• SWFTools
• FFMPEG_wrapper

21. How To Define New Regions in Drupal

To add regions for Drupal 5.x
ADD this code in its entirety to the bottom of your template.php file:
/** Define the regions **/
function framework_regions() {
return array(
'left' => t('left sidebar'),
'right' => t('right sidebar'),
'content' => t('content'),
'header' => t('header'),
'footer' => t('footer'),
'newregion' => t('new region'),
);
}
Replace "newregion" with what you would like to call that region instead. Note that the name on the left before the = is the machine readable format, and cannot have spaces. the name after the = is the human readable format, and can have spaces, capital letters etc. You may add as many regions as you like in the same manner that "newregion" has been added in the example above.
Then, in your page.tpl.php file, define where you would like you regions to be using a print call like so:
You need to replace "newregion" with what you named your region. The id, class and any other html can be changed to anything.

To add regions for Drupal 6.x
ADD the following code to you themename.info file:
regions[left] = Left sidebar
regions[right] = Right sidebar
regions[content] = Content
regions[header] = Header
regions[footer] = Footer
regions[newregion] = New Region

The internal "machine" readable name in square brackets and the human readable name as the value, e.g., regions[theRegion] = The region label.
The contents of the .info file is cached in the database so altering it will not be noticed by Drupal. To clear it, do ONE of the following:
1. Clear button located at "Administer > Site configuration > Performance".
2. With devel block enabled (comes with devel module), click the "Empty cache" link.
3. Simply visit the theme select page at "Administer > Site building > Themes".
Then, in your page.tpl.php file, define where you would like you regions to be using a print call like so:
You need to replace "newregion" with what you named your region. The id, class and any other html can be changed to anything.

18 . How database system of drupal works ?

Drupal stores information in a database; each type of information has its own database table. For instance, the basic information about the nodes of your site are stored in the Node table, and if you use the CCK module to add fields to your nodes, the field information is stored in separate tables. Comments and Users also have their own database tables, and roles, permissions, and other settings are also stored in database tables.

13. What is a Module in drupal ?

13. What is a Module in drupal ?
A module is software (code) that extends Drupal features and/or functionality. Core modules are those included with the main download of Drupal, and you can turn on their functionality without installing additional software. Contributed modules are downloaded from the Modules download section of drupal.org, and installed within your Drupal installation. You can also create your own modules; this requires a thorough understanding of Drupal, PHP programming, and Drupal's module API.
