My Block

class CompanyName_ModuleName_Block_Adminhtml_Catalog_Product_Edit_Tab_Options_Type_Stone extends Mage_Adminhtml_Block_Catalog_Product_Edit_Tab_Options_Type_Abstract
{
public function __construct()
{
    parent::__construct();
    $this->setTemplate('companyname/modulename/catalog/product/edit/options/type/stone.phtml');
    //var_dump($this->hasData('template'));exit;
    $this->setCanEditPrice(true);
    $this->setCanReadPrice(true);
}
}

In my phtml file I var_dump something to test but it doesn't work. var_dump in the block works. And i put my phtml in

design/adminhtml/default/default/template/companyname/modulename/catalog/product/edit/options/type/stone.phtml

Did I do somthing wrong? Any help would be very appreciated.

Thanks.

Answer 1

you can call phtml file by using below code

1) call phtml via block file

class CompanyName_ModuleName_Block_Adminhtml_Catalog_Product_Edit_Tab_Options_Type_Stone extends Mage_Adminhtml_Block_Catalog_Product_Edit_Tab_Options_Type_Abstract
{
    public function __construct()
    {
        parent::__construct();
        $this->setTemplate('modulename/catalog/product/edit/options/type/stone.phtml');
    }
}

your template file should be in

design/adminhtml/default/default/template/modulename/catalog/product/edit/options/type/stone.phtml
