An HTTP requestGET

works with a URL, so variables are always passed in the request URL.

To add q

to the current url, just add &q=SomeValue

where SomeValue

the percentage or url was appropriately .

Joomla 1.5

If you are using Joomla! 1.5 you can use JRequest

to get the value of any variable regardless of whether it is posted POST

or GET

see this document about finding a query variable . 

$q = JRequest::getVar('q');

Joomla 1.6 +



For Joomla! 1.6+ is recommended to use JInput

for retrieving query data as it is JRequest

depreciated, but for Joomla! 3.0+ you MUST use JInput

as it JRequest

has funcitonality removed and will continue to disappear over the next few releases.

To use JInput

, you can either get the current object or chain through the current Joomla app to retrieve the variables.

Receiving JInput 

$jAp = JFactory::getApplication();  // Having the Joomla application around is also useful
$jInput = $jAp->input;  // This is the input object
$q = $jInput->get('q');  // Your variable, of course get() support other option...

Use JInput

through a chain

$jAp = JFactory::getApplication();  // Having the Joomla application around is also useful
$q = $jAp->input->get('q');  // Your variable

You can get GET vars in Joomla using:

$q = JRequest::getVar( 'q' );


This will work for url string like below:

index.php?option=com_google&view=google&q=some_variable
