== Usage ==
#1) To add an 'Add to Cart' button for a product, simply add the following shortcode to a post or page next to the product. Replace PRODUCT-NAME and PRODUCT-PRICE with the actual name and price.

`[wp_cart_button name="PRODUCT-NAME" price="PRODUCT-PRICE"]`

#2) To add the shopping cart to a post or page (eg. checkout page) add the following shortcode to a post or page or use the sidebar widget to add the shopping cart to the sidebar. The shopping cart will only be visible in a post or page when a customer adds a product.

`[show_wp_shopping_cart]`

#3) Alternatively, you have the option to utilize the Gutenberg editor blocks provided by this plugin to conveniently insert the add to cart button and shopping cart in desired locations within your content.

Read the [documentation for using the blocks](https://www.tipsandtricks-hq.com/ecommerce/simple-shopping-cart-blocks)

#4) To insert the 'Add to Cart' button from a template or PHP file, you can utilize the following PHP function:

&lt;?php echo print_wp_cart_button_for_product('PRODUCT-NAME', PRODUCT-PRICE); ?&gt;

Replace PRODUCT-NAME and PRODUCT-PRICE with the actual name and price.

= Using Product Display Box =

Here is an exmaple shortcode that shows you how to use a product display box.

`[wp_cart_display_product name="My Awesome Product" price="25.00" thumbnail="http://www.example.com/images/product-image.jpg" description="This is a short description of the product"]`

Simply replace the values with your product specific data

= Using a compact shopping cart =

Add the following shortcode where you want to show the compact shopping cart:

`[wp_compact_cart]`

= Using Shipping =

To apply a shipping cost to your product, use the 'shipping' parameter. Below is an example of how to include it in a shortcode:

`[wp_cart_button name="Test Product" price="19.95" shipping="4.99"]`

Visit the [shipping setup documentation page](https://www.tipsandtricks-hq.com/ecommerce/wordpress-shopping-cart-how-the-shipping-cost-calculation-works-297) for more details.

= Using Variation Control (Product Variations) =

To enable variation control, use the variation parameter. Below is an example of how to include it in a shortcode:

`[wp_cart_button name="Test Product" price="25.95" var1="VARIATION-NAME|VARIATION1|VARIATION2|VARIATION3"]`

Example shortcode usage:

`[wp_cart_button name="Test Product" price="29.95" var1="Size|small|medium|large"]`

To add multiple variations to a product (such as a second or third variation), use the following format:

`[wp_cart_button name="Test Product" price="29.95" var1="Size|small|medium|large" var2="Color|red|green|blue"]`

To add variations with price modifiers to a product (so the selected variation can update the price), use the following format:
