Override default "Only x left" message

Question

I want to extend default "Only x left" message. Can you tell me which file controls it?

At the moment message is visible only when stock is less than qty threshold. I want if stock is more than qty threshold, to show message "More than qty threshold" and if sock is 0 or below 0(I have activated backorder) to show "Orderable with delivery" message.

Answer 1

Actually you asked 2 questions. To override the template file and override the block function.

The first one is easy.The original file is on vendor/magento/module-catalog-inventory/view/frontend/templates/stockqty/default.phtml. To override this file, you can copy this file and paste it on your active theme. So that app/design/frontend/Your_Vendor/Your_Theme/Magento_CatalogInventory/templates/stockqty/default.phtml. You can start editing it now.

The second one is a bit tricky, but still OK. To override the original threshold function isMsgVisible, you can just modify it a bit.

1. Create a new module. Let's say, MyVendor_CatalogInventory. Create a new file app/code/MyVendor/CatalogInventory/etc/module.xml and add the following content:

   <?xml version="1.0" encoding="UTF-8"?>
   <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
       <module name="MyVendor_CatalogInventory" setup_version="0.0.1"/>
   </config>
   

2. Create new file app/code/MyVendor/CatalogInventory/etc/di.xml and add the following content:

   <?xml version="1.0" encoding="UTF-8"?>
   <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
       <type name="\Magento\CatalogInventory\Block\Stockqty\AbstractStockqty">
           <plugin name="MyVendor_CatalogInventory::aroundIsMsgVisible" type="MyVendor\CatalogInventory\Block\Stockqty" sortOrder="10"/>
       </type>
   </config>
   

3. Create new file app/code/MyVendor/CatalogInventory/Block/Stockqty.php with the following content:

   <?php
   
   namespace MyVendor\CatalogInventory\Block\;
   
   class Stockqty{
   
   
       public function aroundIsMsgVisible()
       {
           //Start your logic here
       }
   }
   

4. Enable this module

   cd <your magento root>
   php bin/magento module:enable MyVendor_CatalogInventory

Answer 2

Will it be possible modifying only default.phtml file to have:

If StockQty > 0 && StockQty < QtyThreshold --- StockQty pcs 

If StockQty > QtyThreshold ---. More than QtyThreshold

If StockQty <=0 ---. With delivery: $stockdelivery (we will have such attribute with drop-down)

And show nothing if In Stock is set to Out of stock.
