How To Add A WC Quantity Discount Table Using Code

This code adds a table for quantity discounts on your single product page in WooCommerce. The table includes a column for the quantity and a column for the discounted price, per unit.

Code Installation

There’s 4 steps :

1. Copy and paste the PHP code to the end of your child themes functions file
2. Modify the values to match your quantity and discount percentages.
3. Copy and paste the CSS to the end of your child themes style.css file.
4. Use a quantity and pricing discounts plugin for WooCommerce to setup and calculate bulk discounts per product.

Here’s the PHP code for your child themes functions file.

add_action( 'woocommerce_single_product_summary', 'display_discount_table', 20 );
function display_discount_table() {

    global $product;
    
    if ( ! $product->is_type( 'simple' ) ) {
        return;
    }

    $discounts = [
        5 => '5%',
        10 => '10%',
        25 => '15%',
        50 => '20%',
        100 => '25%',
        250 => '27%',
        500 => '29%'
    ];

    echo '<table class="discount-table">';
    echo '<thead><tr><th>Quantity</th><th>Discount</th></tr></thead>';
    echo '<tbody>';
    foreach ( $discounts as $quantity => $discount ) {
        echo '<tr><td>' . $quantity . '</td><td>' . $discount . '</td></tr>';
    }
    
    echo '</tbody>';
    echo '</table>';
    

Here’s the CSS for your style.css file or additional CSS field.

.discount-table {
    width: 100%;
    border-collapse: collapse;
    margin-top: 20px;
    font-family: Arial, sans-serif;
}

.discount-table th, .discount-table td {
    border: 1px solid #ddd;
    padding: 8px;
    text-align: center;
}

.discount-table th {
    background-color: #f4f4f4;
    color: #333;
    font-weight: bold;
}

.discount-table tbody tr:nth-child(even) {
    background-color: #f9f9f9;
}

.discount-table tbody tr:hover {
    background-color: #e9e9e9;
}

.discount-table tbody td {
    color: #555;
}

Restrictions

This code only enables you to add the same table with the same values.

If you need a more dynamic solution which :

• Enables you to add unique quantities and discounts per product without editing code.
• Includes the logic to calculate cart values based on the quantity and discounts in your table per product.
• Creates a clickable table rows enabling rapid selection of bulk quantities.
• Includes an extra column for price per unit based on quantity & discount percentage.
• Only requires you to enter numbers on your product edit screen.

Try the Quantity Discount Table Plugin for WooCommerce which you can install as a plugin OR use as code in your child theme. Works exactly the same for both.
