How to remove product_list block from cache in Magento 2?

Question 1

I need to remove the product_list block from cache Class: Magento\Catalog\Block\Product\ListProduct Block: /var/www/html/vendor/magento/module-catalog/view/frontend/templates/product/list.phtml

I have tried these solutions:

public function getCacheLifetime()
{
 return null;
}

I have tried $_isScopePrivate = true; too.

Nothing seems to be working. I need to update the product collection on category list page based upon user input, so I need to remove the block from cache. Please help.

Question 2

Are you sure, that this is a good idea? because all pages with non cached blocks are excluded from full page caching. in your case, all category pages are excluded from full page caching. i think, you have to solve your problem with dynamic loaded content.

if you really want to disable the cache for a specific magento block, you can do it in a xml file. See here.

<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
 <body>
 <referenceContainer name="category.products">
 <block class="Magento\Catalog\Block\Product\ListProduct" name="category.products.list" template="Magento_Catalog::product/list.phtml" cacheable="false"/>
 </referenceContainer>
 </body>
</page>

Question 3

Hi, putting cacheable="false" will remove entire page from cache, won't it?

Question 4

yes. all pages with a non cacheable block on it are excluded from full page cache.

Question 5

So, this is not what I need to achieve. I just need my block out of the cache which is not working for me.

Question 6

yes, but if you have just one block on a page, the whole page is excluded from full page cache. this is a magento behavior. if you can live with that, try the xml solution in my answer to exclude the block from cache.

Question 7

Sorry, this solution won't work as we definitely cannot exclude entire page from FPC.
