I have to pass a variable in layer/view.phtml


to its getChildBlock which is renderer/labels.phtml


I am not able to send a variable, have added a setter & getter in its block file.

Following the layer/view.phtml file the block file I find is $block \Magento\LayeredNavigation\Block\Navigation

I have overridden the vendor file with the following code

class Navigation extends \Magento\LayeredNavigation\Block\Navigation

   private $_filter;

   public function setCustomVariable($filter){
   $this->_filter = $filter;

   public function getCustomVariable(){
    return $this->_filter;

I want something like that

<div class="filter-options-content"><?php /* @escapeNotVerified */ echo $block->getChildBlock('renderer')->setCustomVariable($customData)->render($filter); ?></div>

and in the child HTML which is layer/filter/category/items/renderer/labels.phtml


but it doesn't set the variable in layer/view.phtml and not able to get the value in its child phtml renderer/labels.phtml

So upon digging I find the catalog_category_view_type_layered.xml in vendor which


 <attribute name="class" value="page-with-filter"/>
    <referenceContainer name="sidebar.main">
        <block class="Magento\LayeredNavigation\Block\Navigation\Category" name="catalog.leftnav" before="-" template="Magento_LayeredNavigation::layer/view.phtml">
            <block class="Magento\LayeredNavigation\Block\Navigation\State" name="catalog.navigation.state" as="state" />
            <block class="Magento\LayeredNavigation\Block\Navigation\FilterRenderer" name="catalog.navigation.renderer" as="renderer" template="Magento_LayeredNavigation::layer/filter.phtml"/>

This say Magento_LayeredNavigation::layer/view.phtml has block file Magento\LayeredNavigation\Block\Navigation\Category which doesnt even exist in my code base of vendor.

Magento\LayeredNavigation\Block\Navigation\State and Magento\LayeredNavigation\Block\Navigation\FilterRenderer is there in the vendor block folder but no Magento\LayeredNavigation\Block\Navigation\Category.

enter image description here

At first, I have overridden the Navigation.php which is under Block\Nagivation.

  • You want to set value in $filter object? Nov 14, 2019 at 6:23
  • No... a different variable... i just named the getter and setter that way as it was related to filter

  • But, in $filter object you can pass array/Object which you want. Then, you want to add in custom function? Nov 14, 2019 at 6:31
  • @RohanHapani you mean in $filter object I can set my custom variable and retrieve it in the child phtml ?

You can set value in $filter object and access in your labels.phtml.

Add this code in your layer/view.phtml file :

<?= $filter->setData('custom_variable','custom_value');
<div class="filter-options-content"><?php /* @escapeNotVerified */ echo $block->getChildBlock('renderer')->setCustomVariable($customData)->render($filter); ?></div>

Now, access in your labels.phtml :




Clean cache and check it.

  • Can you tell me what does render($filter) function does on getChildBlock....
