我无法从控制器访问数据来查看（tpl = template）OpenCart

Question

Can't access variable data from controller to view(template tpl file) I have very basic function

public function index() {
$message = "hello";
return $this->load->view('common/hello.tpl', $message );
} 


In view template i try to get $message variable but not defined

<?php echo $message; ?>

public function index() {
$message = "hello";
return $this->load->view('common/hello.tpl', $message );
} 

In view template hello.tpl i try to get $message variable but not defined

This is only example. I have model which must load but for now I need only to access from Controller to View.... Help..

In your given code, the template has no chance to know anything about a variable called $message as you only transmit the value of that variable. According to another SO thread, you should add that variable an array like $data like this:

$data['message'] = $message;

This makes the content of $message available under the same name in your template. If you change the key (eg. to $data['otherKey']), it will get available under $otherKey

Afterwards, transmit that value array to the view method:

return $this->load->view('common/hello.tpl', $data );
