Send data from the controller to phtml

Question

I have this controller:

...
public function insertAction() {
    $something = 'testcase';
    $this->loadLayout();
    $this->_title($this->__("the title"));
    $this->renderLayout();
}
...

I would like to access $something in my .phtml document, how do I do this? (or to put it in another way: how can I access $something in my .phtml file)

Answer 1

There are a couple of ways to do this.

Assign directly to the Block:

$block->assign($var);

or

$block->assign(array('myvar'=>'value','anothervar'=>true));

Then you can access it in the phtml file like this:

$this->myvar

Use the Mage registry:

Mage::register('custom_var', $var);

and then use it like:

$var = Mage::registry('custom_var');

Answer 2

Your phtml must be rendered by a block. The block must have a name in the layout.
You can do this after calling $this->loadLayout();

$block = Mage::app()->getLayout()->getBlock('block_name_here')
if ($block){//check if block actually exists
   $block->setSomething($something);
}

Then you can get the value in the phtml file like

$value = $this->getSomething();
//or 
$value = $this->getData('something');

Answer 3

In case you people missed there is one more way to get this done

using sessions

Mage::getSingleton('core/session')->setSomeSessionVar($data);// In the Controller
$data = Mage::getSingleton('core/session')->getSomeSessionVar(); // In the View;

Answer 4

If you're within your block controller.

class module_namespace_Block_example extends Mage_Core_Block_Template 
{
      protected $_var;

     public function __construct(){

         $this->_var = "something"; 


     }
}

Then in your .phtml file

   <?php 
        $variable = $this->_var;
        echo $variable; // prints "something"

   ?>

   <h1>You're inside your phtml file...... <?php echo $variable;  //prints "something" ?></h1>

Answer 5

this is very easy to send data from controller to phtml file.

Step1:- Firstly create the Model class and extends from Varien_Object

class Namespace_Modulename_Model_Modelfilename extends Varien_Object
{

}

step2:- Now Open the contollerfile and put the code in the function.

$name='gaurav';
$this->loadLayout();
Mage::getSingleton('Modulename/Modelfilename')->setData('name',$name);
$this->renderLayout();

Step3:- Open the phtml file and put the code.

echo $name=Mage::getSingleton('Modulename/Modelfilename')->getData('name');

Output:- 'gaurav';
