This plugin requires <a href="https://wordpress.org/plugins/woocommerce/" title="WooCommerce" rel="ugc">WooCommerce</a>. It allows the site owner to prevent a product from being purchased by enabling a checkbox. It also allows you to override the message on a per-product basis. This will be useful for when you want to let customers know a product is only available in-store but still have the product listed on your website.
How does it work?
This is a very simple plugin that hooks into WooCommerce’s woocommerce_is_purchasable filter. When a product is deemed unpurchasable the “add to cart” button on the main product listing is replaced with a “read more” button. When the customer views the single product page they are shown a message that the product is not available for purchase and the add to cart buttons are removed.

Easy Digital Downloads

Chris Klosowski

This plugin requires <a href="https://wordpress.org/plugins/easy-digital-downloads/" title="Easy Digital Downloads" rel="ugc">Easy Digital Downloads</a>. It outputs gravatars of all the customers who have purchased your product.
It works by using the customer’s email that they used to purchase your product, and checking it against Gravatar.com. Only unique email addresses are used, so if a customer purchases your product more than once, it will only show their Gravatar once.
To show the Gravatars of customers who have purchased your product, use the [edd_purchase_gravatars] shortcode, or drag the provided widget into the sidebar of your single download page. You can also show the gravatars of a particular product anywhere on your website using the template tag or shortcode, by passing in the download’s ID.

Shortcode usage
To show the purchase gravatars on a single download, add this shortcode into the WP editor:
<pre><code>[edd_purchase_gravatars]
</code></pre>
To show the purchase gravatars of a particular download on another page or download, add the id parameter. This example will show the download with an ID of 942.
<pre><code>[edd_purchase_gravatars id="942"]
</code></pre>
To show the purchase gravatars with a custom title, use the title parameter. This will override the heading in the main plugin options
<pre><code>[edd_purchase_gravatars title="This is my custom title"]
</code></pre>
Template Tag usage
This example will show the purchase gravatars of whichever single download it is placed on.
<pre><code>$gravatars = new EDD_Purchase_Gravatars();
echo $gravatars->gravatars( get_the_ID() );
</code></pre>
If you’d like to show purchase gravatars of a specific download from somewhere else on your site, pass in the ID of the download like so:
<pre><code>$gravatars = new EDD_Purchase_Gravatars();
echo $gravatars->gravatars( '942' );
</code></pre>
To show a custom title, pass in your title as the 2nd parameter
<pre><code>$gravatars = new EDD_Purchase_Gravatars();
echo $gravatars->gravatars( get_the_ID(), 'This is my custom title' );
</code></pre>
Widget usage
Drag the widget into your sidebar. If the widget is shown on a single download page, and that download has purchases, the purchase gravatars will be shown.
