WooCommerce Cart Link Admin Bar

A WordPress plugin that adds a convenient cart link to the WordPress admin bar, allowing users to quickly copy a checkout link with their current cart contents.

Description

The WooCommerce Cart Link Admin Bar plugin enhances the WordPress admin bar by adding a "Copy Checkout Link" button that appears when users are on the cart page. This button fetches the current cart contents using the WooCommerce Store API and generates a checkout link that includes all products and applied coupons, which can then be copied to the clipboard with a single click.

Features

• Admin Bar Integration: Adds a cart link button to the WordPress admin bar
• Smart Cart Detection: Only shows the button when users are on the cart page
• WooCommerce Store API Integration: Uses the modern WooCommerce Store API to fetch cart data
• Automatic Link Generation: Generates checkout links with product IDs, quantities, and coupon codes
• Clipboard Integration: Copies the generated checkout link to the clipboard automatically
• Visual Feedback: Provides visual confirmation when the link is copied
• Fallback Support: Includes fallback clipboard functionality for older browsers
• Clean UI: Uses WordPress dashicons for consistent styling

Requirements

• WordPress 5.0 or higher
• WooCommerce plugin 10.0.0 or higher (active)
• PHP 7.4 or higher
• Modern web browser with clipboard API support (fallback available for older browsers)

Installation

Method 1: Manual Installation

1. Download the plugin files
2. Upload the woo-cart-link-admin-bar folder to the /wp-content/plugins/ directory
3. Activate the plugin through the 'Plugins' menu in WordPress
4. Navigate to your cart page to see the new admin bar button

Method 2: Git Clone

Usage

1. Navigate to Cart Page: Go to your WooCommerce cart page (/cart/)
2. Locate Admin Bar Button: Look for the "Copy Checkout Link" button in the WordPress admin bar
3. Click to Copy: Click the button to automatically copy the checkout link to your clipboard
4. Share the Link: Paste the copied link anywhere to share your cart contents

How It Works

The plugin works by:

1. Detecting Cart Page: Only shows the button when users are on the cart page
2. Fetching Cart Data: Uses the WooCommerce Store API to get current cart contents
3. Generating Checkout Link: Creates a URL with product IDs, quantities, and coupon codes
4. Copying to Clipboard: Automatically copies the generated link to the clipboard
5. Providing Feedback: Shows visual confirmation that the link was copied

Generated Link Format

The plugin generates checkout links in the following format:

https://yoursite.com/checkout-link/?products=123:2,456:1&coupon=SAVE10

Where:

• products parameter contains product_id:quantity pairs
• coupon parameter contains applied coupon codes (if any)

Configuration

The plugin requires no configuration and works out of the box. However, you may need to ensure:

1. WooCommerce is Active: The plugin requires WooCommerce to be installed and activated
2. Admin Bar is Visible: The admin bar must be visible for the button to appear
3. Cart Page Exists: Your site must have a cart page at /cart/

Browser Compatibility
