Regarding Variable Product

You actually don’t need code for this :). WooCommerce has a ”
Default Form Values” option on the page where you manage variations.

See https://docs.woocommerce.com/document/variable-product/#setting-defaults for information on how to use it.

Hello Justin,

Thank you very much for your reply, this what I need. But I have more than 5000 products now including one and more variables. So, is there any options to replace all the single variation at a time or I need to do it manually one by one?

Looking forward to your reply. Thank you.

If you’re comfortable with development, you could add a custom column to the CSV importer in WooCommerce core:
https://github.com/woocommerce/woocommerce/wiki/Product-CSV-Importer-&-Exporter#mapping-screen

Otherwise, I can recommend our Product CSV Importer, which supports default variations.

Here’s the plugin:
https://woocommerce.com/products/product-csv-import-suite/

And here’s how to set it up to use default variations: https://docs.woocommerce.com/document/product-csv-import-suite-importing-product-variations/#section-1

Hello,

Thank you very much for your reply, it’s suitable to add custom column.

I have another question. How can I set a particular color for a particular size?
For example when I select a particular size for a product the default color for that size will automatically selected.

Example site: https://pooltech.invocrea.com/product/vita-spa/

Here when you select a value in “Bredde” the other sections are automatically change as per the first section.

Please suggest me how to do that. Looking forward to your reply.

Thank you.

So if the customer chooses “Bredde”, the other settings have defaults based on the selected value of “Bredde”?

In that case, you’re starting to move beyond what WooCommerce can handle, and would need to look at customizations like Gravity Forms. The WooCommerce Gravity Forms Product Add-ons can do what you need:
https://woocommerce.com/products/gravity-forms-add-ons/

You’d need both Gravity Forms and the WooCommerce Gravity Forms Product Add-ons.

Hope that helps you in the right direction!
