(Magento 2) Modify Select.php in Vendor Module-Catalog

Question

I want to override the "Select.php" file at: /vendor/magento/module-catalog/Block/Product/View/Options/Type/ but I'm not sure where to put the modified "Select.php" file. The only thing I changed was commenting out the "--Please Select--" line 47.

Where do I put the modified "Select.php" file?

I am using stock Magento theme.

Thank you.

You need to write a small module to override this file.

1. Create a module under

   app/code//Catalog/

2. Create module.xml under app/code/<vendor_name>/Catalog/etc:

   <?xml version="1.0"?>
   <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
       <module name="<vendor_name>_Catalog" setup_version="1.0.0"/>
   </config>
   

3. Create registraion.php on module root folder, that is app/code/<vendor_name>/Catalog/:

   <?php
   
   \Magento\Framework\Component\ComponentRegistrar::register(
       \Magento\Framework\Component\ComponentRegistrar::MODULE,
       '<vendor_name>_Catalog',
       __DIR__
   );
   ?>
   

4. Create di.xml under app/code/<vendor_name>/Catalog/etc:

   <?xml version="1.0"?>
   <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
       <preference for="Magento\Catalog\Block\Product\View\Options\Type\Select" type="<vendor_name>\Catalog\Block\Product\View\Options\Type\Select" />
   </config>
   

5. Finally, create Select.php under app/code/<vendor_name>/Catalog/Block/Product/View/Options/Type. The file should be look like this:

   <?php
   
   namespace <vendor_name>\Catalog\Block\Product\View\Options\Type;
   
   class Select extends \Magento\Catalog\Block\Product\View\Options\Type\Select
   {
       public function getValuesHtml()
       {
           //do your stuff
   
       }
   }
   

You should able to override the getValuesHtml functions on template file.
