Magento – Programmatically inject header mini cart

blocksce-1.9.0.1checkout

I'm trying to update my header mini cart dynamically by creating a new block, I've tried several ways including:

$this->loadLayout();
$block = $this->getLayout()->createBlock(
    'Mage_Checkout_Block_Cart',
    //'checkout/cart', // OR 'Mage_Checkout_Block_Cart'
    'minicart_content',
    array('template' => 'ajax/checkout/cart/sidebar/default.phtml')
);

$this->getLayout()->getBlock('content')->append($block);
//Release layout stream... lol... sounds fancy
$this->renderLayout();

And also

$block = $this->getLayout()->createBlock('checkout/cart')->setTemplate('ajax/checkout/cart/sidebar/default.phtml')->toHtml();

They always come back empty, I can get it to bring back static content fine. Any ideas please?

In your module/controller/CartController.php action (or another) :

$data["cart_sidebar"] = $this->getLayout()
->createBlock('checkout/cart_sidebar')
->setTemplate('checkout/cart/minicart/items.phtml')
->addItemRender("default", "checkout/cart_item_renderer", "checkout/cart/minicart/default.phtml")
->addItemRender("simple", "checkout/cart_item_renderer", "checkout/cart/minicart/default.phtml")
->addItemRender("grouped", "checkout/cart_item_renderer_grouped", "checkout/cart/minicart/default.phtml")
 ->addItemRender("configurable", "checkout/cart_item_renderer_configurable", "checkout/cart/minicart/default.phtml")
 ->toHtml();

You can use json to serialize your data.

Then have just to put in your js :

jQuery(".block.block-cart").html(data.cart_sidebar);

If you want upgrade cart qty, serialize it too ;)

Magento – programmatically create block to inject on checkout page in magento

the saveBillingAction is not a regular action. It does not return a full page.
It does not have a layout to it. It just returns a JSON that is evaluated by the js in charge of the checkout.

If you want to display something in the page after the saveBillingAction is executed you can try to add that html as a section of the returned JSON and then modify the opcheckout.js file so you can inject that html in the section you need.

You can try this. I didn't test this code.

class My_Details_Block_Product extends Mage_Core_Block_Template
{
    protected $_template = 'details/product_details.phtml';

    protected function _prepareLayout() {
        if ($addToTabBlock = $this->getLayout()->getBlock('product.description')) {

            //sets this block as child to description block
            $addToTabBlock->setChild( 'my.custom.block',$this->getLayout()->createBlock( $this,'my.custom.block',array('template' => 'details/product_details.phtml')));
        }
        return parent::_prepareLayout();
    }
}

You may need to call this block in description.phtml as like this

<div><?php echo $this->getChildHtml('my.custom.block');  ?> </div>

in the desired position
