WooCommerce: Display Stock Status For External Products
By default, WooCommerce external products do not have and do not display any stock, as they are simple redirects to an external URL. This may be unfortunate, because before clicking on an external URL and send people away from your website, you may want to make sure the current item is in stock (so that you have more chances to convert the sale and earn a referral commission, if that’s your business model).
So, how do we “manage stock” for an external product, and display the stock status on the single product page, just before the “Buy Product” button?
PHP Snippet: Show Stock Availability @ WooCommerce Single External Product Page
Before you use the snippet below, you first need to “set” the external product stock status via a custom field that we’ll call “extstock“. I set its value to either 1 (in stock) or 0 (out of stock). You can of course rename it to whatever you want it, redefine values, use it as stock quantity as opposed to stock status, and even “get” it from another custom field defined by a plugin:
You can place PHP snippets at the bottom of your child theme functions.php file (delete "?>" if you have it there). CSS, on the other hand, goes in your child theme style.css file. Make sure you know what you are doing when editing such files - if you need more guidance, please take a look at my free video tutorial "Where to Place WooCommerce Customization?"
Does this snippet (still) work?
Please let me know in the comments if everything worked as expected. I would be happy to revise the snippet if you report otherwise (please provide screenshots). I have tested this code with Storefront theme, the WooCommerce version listed above and a WordPress-friendly hosting on PHP 7.3.
