So laden Sie alle untergeordneten Blöcke in die Steuerung

Ich verwende Ajax zum Hinzufügen zum Warenkorb, daher muss die Seitenleiste des Warenkorbs aktualisiert werden.

Ich habe versucht, diesen Code in Controller, um den Block zu rendern.

Mage::app()->getLayout()->getBlockSingleton('page/html')->setTemplate("page/html/upper.phtml")->toHtml();

Der übergeordnete Block wird jedoch nicht und die untergeordneten Blöcke nicht gerendert.

Und Layoutdatei ist

   <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>

Wie kann ich einen untergeordneten Block im Controller rendern?

Assistiere mir.

Bitte versuchen Sie diesen Code: -

$layout         = Mage::app()->getLayout();
 $block_header   = $layout->createBlock('block/block')->setTemplate('template_url');

 $block_links1  = $layout->createBlock('block/block','block_name')->setTemplate('template_url');
 $block_header->setChild('block_as',$block_links1);

 $block_links2  = $layout->createBlock('block/block','block_name')->setTemplate('template_url');
 $block_header->setChild('block_as',$block_links2);

 $block_links    = $layout->createBlock('block/block','block_name')->setTemplate('template_url');
 $block_header->setChild('block_as',$block_links);

 $block_links->addItemRender('configurable','checkout/cart_item_renderer_configurable','checkout/cart/sidebar/default.phtml');
 $slide = $block_header->toHtml();

Ich habe den folgenden Code ausprobiert:

$layout         = Mage::app()->getLayout();
$block_header   = $layout->createBlock('page/html')->setTemplate('page/html/upper.phtml');
$block_links1   = $layout->createBlock('grana_checkout/sidebar','grana_checkout_topbar')->setTemplate('grana/checkout/topbar.phtml');
$block_header->setChild('grana_topbar',$block_links1);
$block_links2   = $layout->createBlock('box/box','active.grana.box')->setTemplate('grana/box.phtml');
$block_header->setChild('grana_box',$block_links2);
$block_links    = $layout->createBlock('checkout/cart','top.cart')->setTemplate('checkout/topcart.phtml');
$block_header->setChild('cart_overview',$block_links);
$block_links->addItemRender('configurable','checkout/cart_item_renderer_configurable','checkout/cart/sidebar/default.phtml');
$slide = $block_header->toHtml();
