Magento – Block->toHtml() dosn’t have template

magento-1.9template

I have a function like that:

public function aAction()
{
    $productId = $this->getRequest()->getParam('id');
    $block = Mage::getBlockSingleton('catalog/product_view_options');
    $product = Mage::getModel('catalog/product')->load($productId);
    $block->setProduct($product);
    echo $block->toHtml();
}

the method toHtml doesn't have a template set and returns nothing.
How can I fix it?

public function aAction()
{
    $productId = $this->getRequest()->getParam('id');
    $block = Mage::getBlockSingleton('catalog/product_view_options');
    //add this line.
    $block->setTemplate('catalog/product/view/options.phtml');
    $product = Mage::getModel('catalog/product')->load($productId);
    $block->setProduct($product);
    echo $block->toHtml();
}

But this might now work properly because the options block makes use of options renderes to render different types of options.

So you can try this:

public function aAction()
{
    $productId = $this->getRequest()->getParam('id');
    $optionRenderers = array(
          'text' => array (
               'block' => ' catalog/product_view_options_type_text',
               'template' => 'catalog/product/view/options/type/text.phtml',
           ),
           'file' => array (
               'block' => ' catalog/product_view_options_type_file',
               'template' => 'catalog/product/view/options/type/file.phtml',
           ),
           'select' => array (
               'block' => ' catalog/product_view_options_type_select',
               'template' => 'catalog/product/view/options/type/select.phtml',
           ),
           'date' => array (
               'block' => ' catalog/product_view_options_type_date',
               'template' => 'catalog/product/view/options/type/date.phtml',
           ),
    )
    $block = Mage::getBlockSingleton('catalog/product_view_options');
    $block->setTemplate('catalog/product/view/options.phtml');
    foreach ($optionRenderers as $type => $settings) {
        $block->addOptionRenderer($type, $settings['block'], $settings['template']);
    }
    $product = Mage::getModel('catalog/product')->load($productId);
    $block->setProduct($product);
    echo $block->toHtml();
}

Where to Place Templates of an Adminhtml Block in Magento

By default Magento does not offer a package/theme setting for the admin section and it uses default/default

Placing your template into
app/design/adminhtml/default/default/template/mydesign/catalog/product/edit/options/type/test.phtml should do the trick.

Theme fallback also works so you can use
app/design/adminhtml/base/default/template/mydesign/catalog/product/edit/options/type/test.phtml
as well, but I haven't seen base used widely for admin themes yet.

If you want to be able to use a custom admin theme (app/design/adminhtml/mydesign/default/) please see this blog post outlining different options.

Magento – How to call Mage_Page_Block_Html_Pager class in list.phtml

There are two ways of doing this. One is slightly easier than the other.

Add After getToolbarHtml call

If you do it after the call to getToolbarHtml in the list.phtml then the following code will work.

<?php echo $this->getChild('product_list_toolbar')->getChild('product_list_toolbar_pager')->getNextPageUrl() ?>

This is because the pager is actually inside the toolbar and not the list, see layout xml.

<block type="catalog/product_list" name="product_list" template="catalog/product/list.phtml">
    <block type="catalog/product_list_toolbar" name="product_list_toolbar" template="catalog/product/list/toolbar.phtml">
        <block type="page/html_pager" name="product_list_toolbar_pager"/>

And most importantly the collection is setup in the toolbar's getPagerHtml function:

public function getPagerHtml()
{
    $pagerBlock = $this->getChild('product_list_toolbar_pager');

    if ($pagerBlock instanceof Varien_Object) {

        /* @var $pagerBlock Mage_Page_Block_Html_Pager */
        $pagerBlock->setAvailableLimit($this->getAvailableLimit());

        $pagerBlock->setUseContainer(false)
            ->setShowPerPage(false)
            ->setShowAmounts(false)
            ->setLimitVarName($this->getLimitVarName())
            ->setPageVarName($this->getPageVarName())
            ->setLimit($this->getLimit())
            ->setFrameLength(Mage::getStoreConfig('design/pagination/pagination_frame'))
            ->setJump(Mage::getStoreConfig('design/pagination/pagination_frame_skip'))
            ->setCollection($this->getCollection());

        return $pagerBlock->toHtml();
    }

    return '';
}

Add before getToolbarHtml call

Or if you simply want to put it anywhere in the template what you can do is set the collection using the list`s collection with the following code.

$productCollection = $this->getLoadedProductCollection();
$pagerBlock = $this->getChild('product_list_toolbar')->getChild('product_list_toolbar_pager');
$pagerBlock->setCollection($productCollection);
echo $pagerBlock->getNextPageUrl();
