Transfer Values Between Controller/View #top

Let's say you have a indexController.php controller in your controller directory, and you want to set a variable in your view file. There is lots of methods to do that like ObjectMapper of Ness framework, but in classic way you need to define a variable in your view file;

                                  
...HTML CODES
<?= $this->sayhello; ?>
...HTML CODES
                        

And in your controller;

class indexController extends Ness\Controller{


    public function IndexAction($param=0)
    {
            $this->View->sayhello = "Hello World :)"; 
            $this->View->Render("test.php");
    }
}
                              

Examples #top

Check if View file is available

$this->View->isAvailable("home\index.php");

will look for Application/View/home/index.php


Check if view file is anywhere else

$this->View->isAvailable("test_folder\index.php", false);

will look for Application/test_folder/index.php



Load if view exists

if($this->View->isAvailable("home/home.php"))
{
    $this->View->Render("home/home.php");
}else{
    $this->Content->Render("View Not Found");
}
