• autoAssignLicensesOnUserRegistration (boolean) – Whether licenses should be automatically assigned to newly-registered users if the emails match. (Default is true.)

• requireLoggedInUser (boolean) – Whether a user must be logged in when completing an order with at least one digital product in the cart. (Default is false.)

Plugin Hooks

Digital Products offers a few hooks that enable other plugins to modify its behavior:

• digitalProducts_modifyLicenseKey – Gives plugins a chance to modify a license key when it’s getting generated.

• digitalProducts_modifyProductSources – Gives plugins a chance to modify the sources on digital product indexes.

• digitalProducts_defineAdditionalProductTableAttributes – Gives plugins a chance to add additional available table attributes to digital product indexes.

• digitalProducts_getProductTableAttributeHtml – Gives plugins a chance to override the HTML of the table cells on digital product indexes.

Eager loading

Both licenses and products have several eager-loadable properties

Licenses

• product - Allows you to eager-load the product associated with the license.
• order - Allows you to eager-load the order associated with the license, if any.
• owner - Allows you to eager-load the Craft user that owns the license, if any.

Products

• isLicensed - Eager-loads whether the product is licensed for the currently logged in Craft User.

Examples

Displaying the licensed product for the currently logged in Craft User.

    {% if currentUser %}
        {% set licenses = craft.digitalProducts.licenses.owner(currentUser).with(['products', 'order']) %}

        <div class="panel panel-default">
        <div class="panel-heading"><h3 class="panel-title">Licenses</h3></div>
        {% if licenses %}
            <table class="table">
                <thead>
                    <tr>
                        <th>Licensed product</th>
                        <th>License date</th>
                        <th>Order</th>
                    </tr>
                </thead>
                <tbody>
                {% for license in licenses %}
                    <tr>
                        <td><a href="{{ license.product.getUrl() }}">{{ license.product.title }}</a></td>
                        <td>{{ license.dateCreated|date('Y-m-d H:i:s') }}</td>
                        <td>
                            {% if license.orderId %}
                                <a href="/store/order?number={{ license.order.number }}">Order no. {{ license.orderId }}</a>
                            {% endif %}
                        </td>
                    </tr>
                {% endfor %}
                </tbody>
            </table>
        {% endif %}
    {% else %}
        <p>Please log in first</p>
    {% endif %}

Checking if currently logged in user is licensed to access a product.

    {% set products = craft.digitalProducts.products({type: 'onlineCourses'}).with(['isLicensed']) %}
    {% if products %}
        <table class="table">
            <thead>
                <tr>
                    <th>Product</th>
                    <th>License status</th>
                </tr>
            </thead>
            <tbody>
                {% for product in products %}
                    <tr>
                        <td>{{ product.title }}</td>
                        <td>
                            {% if product.isLicensed() %}
                                You already own this product.
                            {% else %}
                                <a href="{{ product.getUrl() }}">Get it now!</a>
                            {% endif %}
                        </td>
                    </tr>
                {% endfor %}
