Back in Stock Notification for Site Contacts

Collection

For this example we added a collection called ‘backInStock‘ that contains data about the site visitors that need to get the notifications and the products that they need to be notified about, as well as more information about the visitor’s notification status.

Pages & Lightboxes

Our site contains the following pages and lightboxes:

• Enter Details lightbox: for registering the site visitor for back-in-stock notifications.

• Product page with a ‘Notify Me When Back In Stock’ button

• ‘EmailConfirmation (ID)’ dynamic page: This is the landing page seen on the site when the site visitor confirms their email. This page is hidden from the site menu and search engines.

Backend files

Our site contains the following backend files:

• backInStock.jsw: Contains the back-in-stock functionality handler.

• Jobs.config: The cron configuration file for the Job Scheduler.

Code

Note: If you didn’t add a members area to the site, you can’t test the site with your owner or contributor email. You can test the site with a different email address.

Note: In order to make this example work in your account you need to change the URL constant in backInStock.jsw to you site's URL.

Our site contains code that performs the following actions:

1. In the product page, get the product data and check whether the product is in stock. If the product is out of stock, add a ‘Notify me when back in stock’ button.

2. If a site visitor clicks the button, do the following:

3. Since you can’t create a contact that is already a member, check if the visitor is a logged-in member. If they are, the first name, last name, and email inputs are populated with their information. If they’re not a logged-in member, the site visitor enters their information in the inputs.

4. When the site visitor clicks the ‘Submit’ button, validate the input fields, create a contact for the site visitor if they’re not a member, and insert the contact information into the ‘backInStock’ collection.

5. If the insertion is successful, show a text message informing them that they were sent a verification email. Otherwise, show an error text message.

6. When the site visitor confirms their email, show the ‘BackInStock Emailconfirmation (ID)’ dynamic page with a success or failure message and update the visitor’s status in the `backInStock` collection.

7. Use the Job Scheduler to check every hour whether the product is back in stock. If it’s back in stock, send the visitor a triggered email.
