Joomla Component error - Fatal error - arrays

Question

I have installed a ticket module on my Joomla website, I get the following error when a ticket is submitted
Fatal error: Call to undefined method JRegistry::getValue() in /home/xboxfifa/public_html/HD/components/com_jtaghelpdesk/controller.php on line 300
function mailme($formData){
$version = new JVersion();
$body = "A new inquiry has been recieved: <br /> Name : ". $formData['inqName']. "<br /> Email ID : ". $formData['inqEmail']. "<br/> Message : ".$formData['inqMessage'] ;
$mailer =& JFactory::getMailer();
$config =& JFactory::getConfig();
if($version->RELEASE==3.0)
{
$recipient = array(
$config->get('mailfrom'),
$config->get('fromname'));
}else
{
$recipient = array(
$config->getValue( 'config.mailfrom' ),
$config->getValue( 'config.fromname' ));
}
$mailer->addRecipient($recipient);
$subject=$formData['inqSubject'];
$mailer->setSubject($subject);
$mailer->isHTML(true);
$mailer->Encoding = 'base64';
$mailer->setBody($body);
$send =& $mailer->Send();
if ( $send !==true )
{ $msg = 'Reply not Sent!';
} else
{
$msg = 'Reply Sent Successfully!';
}
}
If anyone could help me I would appreciate it.

Answer 1

JRegistry::getvalue() was removed in Joomla 3.x so make sure you use JRegistry::get() instead.
As for your version compare, you should use this:
if (version_compare(JVERSION, '3.0.0', 'ge')){
// code here
}

Answer 2

Editing this answer because I realized the issue is something else. The problem here is the $version check you're doing looks for the release to be EXACTLY == 3.0. When really you want that get() method to be used for 3.0 and up. You should change your if-statement to:
if($version->RELEASE >= 3.0)
{ ... }
Because you're using 3.2.1 this will use the proper method gets for that version.
