How to integrate
Follow these WooCommerce-specific instructions
Get your Waitlister endpoint
Login to Waitlister → Overview → copy your waitlist key. Your form action URL is:https://waitlister.me/s/YOUR_WAITLIST_KEY
Edit WooCommerce single product template
Copy:
-
wp-content/plugins/woocommerce/templates/single-product/add-to-cart/simple.php
to:
-
wp-content/themes/your-theme/woocommerce/single-product/add-to-cart/simple.php,
Add conditional waitlist form
In your overridden template file, add this code after the add-to-cart button:
<?php
// Show waitlist form when product is out of stock
if ( ! $product->is_in_stock() ) : ?>
<div class="woocommerce-waitlist-form">
<h3>Get notified when back in stock</h3>
<form action="https://waitlister.me/s/YOUR_WAITLIST_KEY" method="POST">
<input type="email" name="email" placeholder="Your email" required>
<input type="hidden" name="product_name" value="<?php echo esc_attr( $product->get_name() ); ?>">
<input type="hidden" name="product_id" value="<?php echo esc_attr( $product->get_id() ); ?>">
<input type="hidden" name="product_url" value="<?php echo esc_url( get_permalink() ); ?>">
<button type="submit" class="button">Notify Me</button>
</form>
</div>
<?php endif; ?>Style the waitlist form
Add CSS to match your WooCommerce theme. Add to Appearance → Customize → Additional CSS:
.woocommerce-waitlist-form {
margin: 30px 0;
padding: 25px;
background: #f8f8f8;
border-radius: 5px;
}
.woocommerce-waitlist-form h3 {
margin-bottom: 15px;
font-size: 18px;
}
.woocommerce-waitlist-form input[type="email"] {
width: 100%;
padding: 12px;
margin-bottom: 12px;
border: 1px solid #ddd;
border-radius: 3px;
}
.woocommerce-waitlist-form .button {
width: 100%;
/* Button will inherit your theme's button styles */
}Add to variable products (if needed)
For variable products, copy and modify variable.php template with similar conditional logic checking variant stock status.
Create functions.php helper (optional)
Add reusable function to functions.php for easier maintenance:
function show_waitlist_form($product_id = null) {
if (!$product_id) {
global $product;
$product_id = $product->get_id();
} else {
$product = wc_get_product($product_id);
}
if (!$product->is_in_stock()) {
echo '<div class="woocommerce-waitlist-form">';
echo '<h3>Get notified when back in stock</h3>';
echo '<form action="https://waitlister.me/s/YOUR_KEY" method="POST">';
echo '<input type="email" name="email" placeholder="Your email" required>';
echo '<input type="hidden" name="product_name" value="' . esc_attr($product->get_name()) . '>';
echo '<input type="hidden" name="product_id" value="' . esc_attr($product_id) . '>';
echo '<button type="submit" class="button">Notify Me</button>';
echo '</form>';
echo '</div>';
}
}
// Use in templates:
// show_waitlist_form();Whitelist your store domain
In Waitlister → Settings → Configure → Whitelisted domains, add your WordPress/WooCommerce store URL.
Test with out-of-stock products
