How to Show the Add To Cart Buttons in the Sidebar (Method 1)

We have recently added new shortcodes that uses the WordPress shortcodes API. You can use these shortcodes to place a purchase button for a product on the sidebar widget of your WordPress site:

Here is how to do it:

Step 1) Go to the widgets menu of your WP Admin

Step 2) Add a standard text widget to the sidebar of your site

Step 3) Use one of the shortcodes to create a purchase button for your product that you want to sell:

[wp_cart_button name=”Test Product One” price=”29.95″]

[wp_cart_button name=”Test Product Two” price=”19.95″ shipping=”4.99″]

How to Show the Add To Cart Buttons in the Sidebar (Method 2)

Step 1) Download and activate the Executable PHP code plugin if you don’t have it already (any other PHP executable plugin will work too):

This plugin lets you call php functions from the widgets (it’s similar to the Text widget but it allows you execute PHP code too).

Step 2) Go to the widgets menu and add a ‘PHP Code’ widget to the sidebar (where you want to display the ‘Add to Cart’ buttons or shopping cart). Now you can enter HTML and PHP code here to display whatever you want to show. For example, entering the following line will display an add to cart button:

<?php
$product_name = "Product Name";
$product_price = "10.00";
echo print_wp_cart_button_for_product($product_name, $product_price);
?>

How to Collect Special Instructions from the Customer

If you need to collect special instructions from the customer for some customized work on the item you are selling then you can use the Collect Customer  Input Addon.
