php - Magento 2 - Empty custom widget render -


i try create custom widget on magento 2 ee list products custom attribute 'end_life' yes/no type. it's ok in backoffice, created widget type "end life products" , inserted on homepage.

but render on homepage empty. <p></p>

please me render products list :)

app/code/my/custommodule/etc/module.xml

<?xml version="1.0"?> <config xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xsi:nonamespaceschemalocation="../../../../../lib/internal/magento/framework/module/etc/module.xsd">     <module name="my_custommodule" setup_version="1.0.0">     </module> </config>

app/code/my/custommodule/etc/widget.xml

<?xml version="1.0" encoding="utf-8"?> <widgets xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xsi:nonamespaceschemalocation="../../../magento/widget/etc/widget.xsd">     <widget id="my_custommodule_end_life_products" class="my\custommodule\block\widget\endlifeproducts">         <label translate="true">end life products</label>         <description></description>     </widget> </widgets>

app/code/my/custommodule/block/widget/endlifeproducts.php

namespace my\custommodule\block\widget;  class endlifeproducts extends \magento\framework\view\element\template implements \magento\widget\block\blockinterface {      public function getendlifecollection() {         $objectmanager = \magento\framework\app\objectmanager::getinstance();         /** @var \magento\catalog\model\resourcemodel\product\collection $productcollection */         $productcollection = $objectmanager->create('magento\catalog\model\resourcemodel\product\collection');         $productcollection->addattributetofilter('end_life', true)             ->load();         return $productcollection;     }      public function _tohtml()     {         $this->settemplate('widget/end_life_products.phtml');     } }

app/code/my/custommodule/view/frontend/widget/end_life_products.phtml

<h1>end life products</h1> <?php if ($exist = ($block->getendlifecollection() && $block->getendlifecollection()->getsize())) {     $items = $block->getendlifecollection()->getitems(); }

i found solution :

define template protected $_template variable, , don't define _tohtml() function

namespace my\custommodule\block\widget;  class endlifeproducts extends \magento\framework\view\element\template implements \magento\widget\block\blockinterface {      protected $_template = 'widget/end_life_products.phtml';      public function getendlifecollection() {         $objectmanager = \magento\framework\app\objectmanager::getinstance();         /** @var \magento\catalog\model\resourcemodel\product\collection $productcollection */         $productcollection = $objectmanager->create('magento\catalog\model\resourcemodel\product\collection');         $productcollection->addattributetofilter('end_life', true)             ->load();         return $productcollection;     } }

and put template .phtml in custom module template folder : app/code/my/custommodule/view/frontend/template/widget/end_life_products.phtml
