Configuration and Setup

Step 1: Enable WooCommerce® Compatibility

Ensure WooCommerce® is installed and activated before using this plugin. The plugin will automatically deactivate if WooCommerce® is not active.

Step 2: Configure the Plugin

Upon activation, the plugin creates the following custom database tables:

• Waitlist: Tracks product waitlists by customer email.
• Waitlist History: Records historical waitlist data.
• Notifications: Stores sent notifications for back-in-stock alerts.

These tables are created and maintained automatically.

Step 3: Email Customization

The plugin includes customizable email templates located in:

• templates/emails/back-in-stock-notification.php: HTML version of the back-in-stock email.
• templates/emails/plain/back-in-stock-notification.php: Plain text version of the email.

You can further customize these templates by copying them to your theme folder under woocommerce/emails/ and editing them to match your brand style.

Usage

1. Adding Customers to the Waitlist

• Customers can join a waitlist on a product's single page.
• The waitlist form captures the customer's email, saving it to the waitlist database table.
• The plugin enqueues JavaScript only on out-of-stock single product pages, optimizing performance.

2. Notifying Customers

When stock levels are updated (via WooCommerce®'s product update), the plugin will:

• Check if the product's stock is now above zero.
• Send a back-in-stock email notification to all users on that product's waitlist.
• Log notifications and remove customers from the waitlist after notifying them.

3. Managing Waitlists and Analytics

Admins can access the Back In Stock submenu under WooCommerce®. The dashboard provides insights, including:

• Most Wanted Products: Products with the highest waitlist counts.
• Most Overdue Products: Products that have been out of stock the longest.
• Most Signed-Up Products: Top products based on waitlist sign-ups over time.
• Sign-Ups and Notifications: Daily and monthly sign-up and notification statistics are tracked, with values stored for easy access via a helper class.

4. CSV Exporting

Two CSV export options are available on the Back In Stock dashboard:

• Export Emails: Exports all unique emails from the waitlist history table.
• Export Data: Exports demand insights such as the most wanted, most overdue, and most signed-up products.

Helper Functionality

The plugin introduces a BISN_Data_Helper class to simplify database queries for various waitlist and notification statistics, such as:

• get_most_wanted_products(): Retrieves the top 10 most wanted products based on waitlist count.
• get_most_overdue_products(): Retrieves the top 10 products out of stock the longest.
• get_signups_today(): Counts the sign-ups from today.
• get_sent_today(): Counts notifications sent today.

The helper class enables efficient data retrieval for a streamlined and modular plugin structure.

Customizable Back In Stock Email

The BISN_Back_In_Stock_Email class controls the back-in-stock email notifications, which are sent when products are restocked. Emails are triggered by the bisn_send_back_in_stock_email action, providing seamless integration into WooCommerce's email management system.
