I’ve seen both on the WooThemes Help Desk and on some Facebook groups that customers need to edit many of their products, or even all of them, all together.
In example, you may need to discount all the products for a special offer.
Everybody knows that there are plugins for this, like Dynamic Pricing or Bulk Stock Management, but not everybody knows about a neat feature that WooCommerce includes in its core by default, which allows you to do the same, maybe with more steps.
It’s the Bulk Actions feature, already available by default in WordPress for its default post types, and extended for Products in WooCommerce.
The Bulk Actions it’s a dropdown menu you have in the Products page, on the top left of the table.
To use it, select one or more products in the table, then choose what to do with the Bulk Actions dropdown, so choose Edit or Move to Trash. It’s obvious what would happen if you choose Move to Trash.
If you choose instead to Edit the selected products you will be able to edit a lot of options for those products.
Here is how it looks when you try to edit products in bulk:
As you can see you can choose the categories of the products, change the comments status and the products status, add tags, and change a lot of product data.
In example, if you want to discount all the products in the shop just select all of them, then click on Bulk Actions > Edit and in the PRODUCT DATA section choose how to edit the Price, increasing/decreasing it by X%. This would edit the product regular price by X%.
In the same way, you can bulk edit the stock (if the stock is the same for all products) or allow backorders and a lot of other things.
