Hi Foysal,
I'm new to this so please pardon me if I'm not 100% accurate.
The first line creates the JInput object. Checkout the following doc:
http://docs.joomla.org/JInput_Background_for_Joomla_Platform
The second line executes the task.
Kind regards,
Nick

Hi Foysal,
You're welcome!
getCmd gets a filtered variable. The cmd filter only allows the
characters [A-Za-z0-9.-_]
Check out the following two docs:
http://docs.joomla.org/API15:JRequest/getCmd
http://docs.joomla.org/Secure_coding_guidelines
Kind regards,

Dear Nick Savov,
Thanks for reply.
I think 'task' is a variable here getCmd('task'). My question is where is the source of this variable ?? Where is the production place of this variable ?? What is the value of this variable ??
Thanks
Foysal

Dear Rouven Weßling,
Thanks for reply.
I felt that previously, the task comes from the HTTP request via GET or POST. But why is it 'task' ?? Not 'taskee' or 'atask' or 'mouse' or something else. Where is the source of this 'task' ??

The Jrequst::getCmd, is way of getting data from a php Hash (POST,GET) etc...,
There are more than 6 nor 7 method of JRequest , The base method of this is JRequest getVar,
In php when a form submit happen, if the the form method is POST, How we get the data in php is, $_POST['name'], but in joomla environment, we can get the same thing using JRequest::getVar('name') method, but other methods are jrequest::getInt, jrequest::getString,jrequest::getWord, jrequest::getCmd(), etc.., are getting the post data in a specific filteration......

Hi
Foysal,
I think the 'task' in your example doesn't come from anywhere, and is void in this case. "getCmd('task')" is added in that part of the tutorial for future use, e.g. when there really is a task to perform. It is most commonly used in the backend of a component, where you can find it in the toolbar. Further on in the tutorial you are following, you will see examples.
You can test it yourself by making a form in the frontend, and adding a hidden field with: " name="task" value="do_something" ".

Hi Foysal, Sorry for Late reply,
In this case ,
the file which is hold
$input = JFactory::getApplication()->
Is the entry point to the component (MVC), here when ur component is called,
Joomla looks for a task perameter in the Global Hash (GET, POST), if its not set the default task which ispublic function display will be executed , if joomla found a task perameter, the joomla look for a function in the controller with name which set in the task perameter,
If u need a good place to continue with Joomla MVC, u try to get Packtpub.Mastering.Joomla.1.5.2nd.Edition.May.2010 ebook, their u can get good clarification and understanding, Dont worry about Joomla version, its not big deal if u could learn Joomla 1.5 MVC Trawly, then u could easily move to Joomla 2.5, Only some of the Libabraries are changed from Joomla 1.5 and newever version after that..
In this case ,
the file which is hold
$input = JFactory::getApplication()->
input;
$controller->execute($input->getCmd('task'));
$controller->execute($input->getCmd('task'));

Thanks to all who try to help me. After a long search, I got something(Though I am not so clear so far).
There is a protected variable named $task in line 137 of controller.php file which is kept here E:\xampp\htdocs\new_joomla\libraries\joomla\application\component .
When we are using this function public static function getInstance($prefix,$config = array()) we are putting some thing to that protected variable name $task in line 137 of controller.php
Later when we are trying to get that value using this syntax
If I echo that line I am getting the controller class name that is 'HelloWorldController' .
But I little confused so far, In which point(Where) joomla inserting value and which value joomla inserting in $task variable??
Thanks
Foysal

I saw several component code in newly installed joomla. I got this line of code $controller->execute(JRequest::getCmd('task')); several times. This returns the name of the controller class.
How do you develop a component ??
thanks
Foysal

Dear Foysal,
Just Look at the code of mine in one of a component entry point,
<?php
defined('_JEXEC') or die;
$view = JRequest::getCmd('view');
$task = JRequest::getCmd('task');
$session = JFactory::getSession();
$employer = $session->get('employer_logined', false, 'appcurrentlogin');
if(!$employer){
if(!($view == 'registration' || $task == 'registration.activate' || $task == 'registration.register')){
$app = JFactory::getApplication();
$app ->redirect('index.php', 'You are not authorized to view this page', 'Error');
}
}
jimport('joomla.application.component.controller');
JLoader::register('JobsHelper', dirname(__FILE__) . '/helpers/jobs.php');
$controller = JController::getInstance('Jobs');
$controller ->execute(JRequest::getCmd('task'));
$controller ->redirect();
?>
I think You are confused with Task variable, it just a task. Normally Joomla handle functions by passing a value with the name of task via the hash.. assume you want to submit a form to a particular function in the default controller, , your form action would look like something following...
<form action="index.php?option=com_xxx&task=saveEmployerDetails" method="post">
<!--or you can even past the task value look like this in a hidden field, -->
<input type="hidden" name="task" value="saveEmployerDetails" />
</form>
if task is not set , the Jequest::getCMD('task'); will return null, and joomla will try to execute a default function called display(); if its not also defined, then nothing is executed.....
