“Cart links for WooCommerce” allows the shop manager to create urls that will redirect the customer to a fully populated cart. This is extremely useful for email campaigns or call to action buttons. If the customer already has items in the cart, they will be kept.
The shop manager can easily create the url by populating his own shopping cart, the cart url will be displayed on the cart page. The shop manager can copy this url to the clipboard and paste it anywhere he wants, for example in a promotional email.
The url looks like this: <code>www.example.com?fill_cart=12,2x44</code> 
This url will populate the cart with 1x item with id 12, and 2x item with id 44.

Cart links for WooCommerce

Easily create a url that will populate a cart

This plugin allows adding multiple simple (not variable or grouped) products to the WooCommerce cart using URL parameters. While WooCommerce natively supports adding a single product to the cart via a URL parameter like <code>add-to-cart=product_id&quantity=quantity</code>, this plugin extends that functionality to support multiple products in a single URL.
<h3>How it works:</h3>
<ul>
<li>URL Format: <code>?add-to-cart=product_id:quantity,product_id:quantity,product_id:quantity</code></li>
<li>Single Quantity: If the quantity is not specified (eg. <code>?add-to-cart=product_id,product_id:quantity</code>), the product is added with a quantity of 1.</li>
</ul>
<h3>Examples:</h3>
<ul>
<li>Adding multiple products with specific quantities: 
example.com/cart/?add-to-cart=12:2,34:1,56:5</li>
<li>Adding multiple products with default quantity: 
example.com/cart/?add-to-cart=12,34:2,56</li>
</ul>
<h3>Configuration</h3>
The plugin works out of the box with no configuration required. However, you can optionally define the following constants in your <code>wp-config.php</code> to adjust the default limits:
Maximum products per request (default: 50) 
 define( ‘ADD_MULTIPLE_TO_WC_CART_PRODUCT_LIMIT’, 50 ); 
Limits how many product entries are processed in a single URL. Extra products beyond the limit are silently ignored.
Maximum quantity per product (default: 999) 
 define( ‘ADD_MULTIPLE_TO_WC_CART_QTY_MAXIMUM’, 999 ); 
Caps the quantity of each individual product. Any quantity above this value is clamped to the maximum.
Example — allow up to 10 products with a max qty of 100: 
 define( ‘ADD_MULTIPLE_TO_WC_CART_PRODUCT_LIMIT’, 10 ); 
 define( ‘ADD_MULTIPLE_TO_WC_CART_QTY_MAXIMUM’, 100 );
