* can you please provide a functional example on how to make the variable description
to display on my item page? You mention that the helper ‘wcpvd_get_variation_description’
is needed, but I am not sure how to use this? I am guessing that I need a function
added to my child them functions.php. any help would be appreciated. Thank you

* Ditto on this. Giving us the helper does nothing for us if you don’t also give
a working example of what exactly calls the code. Sounds good in concept, but…
I know I’m not going to spend a lot of time doing the trial and error just to
finally figure out what code you’re using to actually display it. As in the “
echo” part of the function, etc.

* Great! Looking forward to it. I have a few projects that I want to use this on
so the sooner the better.

* The dev just replied to my review of the plugin and outright said if we want
the code snippet that actually makes it work, then we have to pay for it. Shady
extortion. I reported the dev for that one.
* Like I said…as it is right now this free plugin is nonfunctional. You can’t use
it. There is no means of displaying the variation descriptions because the devs
failed to provide a working snippet. Now the dev wants us to extort users for
the snippet. Classy.

* Hi digitaliway!
* I updated the readme.txt and added a F.A.Q.-Section: [https://wordpress.org/plugins/woocommerce-product-variations-description/faq/](https://wordpress.org/plugins/woocommerce-product-variations-description/faq/)
* I hope, that helps,
* Best regards,
Thomas

* That snippet doesn’t help us as users. It is a stop gap measure as the moment
WooCommerce is updated, the plugin will break again. It needs to be a function
added to the theme’s or child theme’s function.php file. One that hooks into
Woocommerce so it remains update proof.

* Here’s just an example of code for the function.php file that uses Woocommerce
hooks. Your plugin should be using this rather than requiring users to edit core
WooCommerce plugin files. Average users aren’t comfortable with doing all of
that supplementary core editing just to get a little field to display….advanced
users aren’t either, especially when there are simpler ways to do this.
* ```
add_action( 'woocommerce_single_product_summary', 'wc_product_sold_count', 11 );
function wc_product_sold_count() {
global $product;
$units_sold = get_post_meta( $product->id, 'total_sales', true );
echo '' . sprintf( __( 'Units Sold: %s', 'woocommerce' ), $units_sold ) . '
';
}
```

* Yes. Which does the trick with the filter `woocommerce_after_add_to_cart_form`.
This filter is update proof and will not be changed within the next minor and
next major updates of WooCommerce.
* There is no out-of-the-box way to display the variation description at once with
the activation of this plugin. It’s just a helper to get things done. Nevertheless,
if you want to have this as a feature request, please use the Github-Issues and
open a new issue. But according to my analyses I really don’t think that it will
become a feature of this plugin.
* This topic here was about a snippet to help with display of the variation description.

* That’s what your “functional code” produces.

* So maybe you don’t have any variations for this product setted. Also you can
add a check to the $variation_ids:
* `if ( empty( $variation_ids ) ) return;`

* I have variation descriptions set. Your code should be where if empty statements
are made. Again, thanks for confirming your code and example is incomplete.
* To top it off, your example styles the entire div to be hidden, so that if anything
was there to be displayed, it still wouldn’t show.

* As written in the F.A.Q:
* > Create a JavaScript or jQuery-Script to get the current selected variation (
> see /woocommerce/single-product/add-to-cart/variable.php for details) and display
> the variation description.
* Also: If you can provide more information about you current setup of products
with its variations, I can help.
* Also, thanks for reading the Support-Advice at the very first page of this plugin

* Heres the code how I did it. Maybe it will help some of you.
In functions.php:
* function additional_information_tab_content() {
// get the product global $product;
* // Get the post IDs of all the product variations
$variation_ids = $product-
>children;
* // check if we have variations
* if ( empty( $variation_ids ) )
return;
* // walk the variations
foreach( $variation_ids as $variation_id ) { $description
= wcpvd_get_variation_description( $variation_id ); $model_name = ‘-‘.get_post_meta(
$variation_id, ‘attribute_pa_zustand’, true); // echo ‘’; echo ‘
’ . ‘
’ . $description.‘
’ . ‘
’; // echo ‘
