I am using Ajax to add to cart, so need to update the cart side bar.
I have try this code in controller to render the block.
Mage::app()->getLayout()->getBlockSingleton('page/html')->setTemplate("page/html/upper.phtml")->toHtml(); but it render the parent block and doesn't render the child blocks.
And layout file is
<block type="core/text_list" name="upper" as="upper" template="page/html/upper.phtml"> <block type="checkout/cart" name="top.cart" as="cart_overview"> <action method="setCartTemplate"><value>checkout/topcart.phtml</value></action> <action method="setEmptyTemplate"><value>checkout/cart/cartEmpty.phtml</value></action> <action method="chooseTemplate"/> <action method="addItemRender"><type>simple</type><block>checkout/cart_item_renderer</block><template>checkout/cart/sidebar/default.phtml</template></action> <action method="addItemRender"><type>grouped</type><block>checkout/cart_item_renderer_grouped</block><template>checkout/cart/sidebar/default.phtml</template></action> <action method="addItemRender"><type>configurable</type><block>checkout/cart_item_renderer_configurable</block><template>checkout/cart/sidebar/default.phtml</template></action> </block> </block> how can i render child block in controller.
