Adds item to cart.

Options

• :selected_specs - Map of selected specifications (for dynamic pricing)

Examples

# Add simple product
add_to_cart(cart, product, 2)

# Add product with specification-based pricing
add_to_cart(cart, product, 1, selected_specs: %{"material" => "PETG", "color" => "Gold"})

Aggregates filter values for sidebar display.

Returns a map of filter_key => aggregated data. For price_range: %{min: Decimal, max: Decimal} For vendor: [%{value: "Vendor", count: 5}, ...] For metadata_option: [%{value: "8 inches", count: 3}, ...]

Options:

• :category_uuid - Scope aggregation to a specific category by UUID

Auto-selects payment option if only one is available.

If cart already has a payment option selected, does nothing. If only one option is available, selects it.

Auto-selects the cheapest available shipping method for a cart.

If cart already has a shipping method selected, does nothing. If only one method is available, selects it. If multiple methods are available, selects the cheapest one.

Bulk delete categories. Returns count of deleted categories. Nullifies category references on orphaned products.

Bulk delete products. Returns count of deleted products.

Bulk update category parent. Returns count of updated categories. Excludes the target parent from the update set to prevent self-reference. Uses a single UPDATE with subquery to resolve parent_uuid.

Bulk update category status. Returns count of updated categories.

Bulk update product category. Returns count of updated products.

Bulk update product status. Returns count of updated products.

Calculates the final price for a product based on selected specifications.

Applies option price modifiers (fixed and percent) to the base price. Fixed modifiers are applied first, then percent modifiers.

Example

product = %Product{price: Decimal.new("20.00")}
selected_specs = %{"material" => "PETG", "finish" => "Premium"}

# If PETG has +$10 fixed and Premium has +20% percent:
calculate_product_price(product, selected_specs)
# => Decimal.new("36.00")  # ($20 + $10) * 1.20

Whether any line in the cart needs physical shipping.

Reads the "requires_shipping" flag snapshotted onto each cart item at add time. Rows created before the snapshot existed fall back to the live product's flag (batched, one query); a line whose product is GONE counts as requiring shipping — the conservative default, since charging shipping on a digital line is a smaller failure than shipping-free physical goods.

Digital-only carts skip the shipping-method requirement, the shipping charge, and the shipping line on the resulting order.

@spec cart_session_id(String.t() | any()) :: String.t() | nil

Returns just the session_id of a cart, without loading items.

Used to authorize order confirmation pages for orders placed BEFORE metadata["session_id"] was recorded on the order itself. Those orders still carry metadata["cart_uuid"], and the cart row survives conversion (mark_cart_converted/2 flips its status, it is never deleted) with its session_id intact — so the placing session is still recoverable for them.

Deliberately a narrow select rather than get_cart/1: this runs on a page load purely to compare one string, and get_cart/1 preloads items and the shipping method.

@spec cart_url(String.t()) :: String.t()

Generates a localized URL for the cart page.

Examples

iex> Shop.cart_url("ru")
"/ru/cart"

iex> Shop.cart_url("en")
"/cart"

@spec catalog_url(String.t()) :: String.t()

Generates a localized URL for the shop catalog.

Examples

iex> Shop.catalog_url("es-ES")
"/es/shop"

iex> Shop.catalog_url("en")
"/shop"

Returns categories as options for select input. Returns list of {localized_name, id} tuples.

Checks if a category slug exists for a language.

iex> Shop.category_slug_exists?("jarrones-macetas", "es-ES")
true

@spec category_url(PhoenixKitEcommerce.Category.t(), String.t()) :: String.t()

Generates a localized URL for a category.

Returns the correct locale-prefixed URL with translated slug.

Parameters

• category - The Category struct
• language - Language code (e.g., "en-US", "ru", "es-ES")

Examples

iex> Shop.category_url(category, "es-ES")
"/es/shop/category/jarrones-macetas"

Examples

iex> Shop.checkout_url("ru")
"/ru/checkout"

iex> Shop.checkout_url("en")
"/checkout"

Clears all items from cart.

Clears the cart's shipping selection and recalculates totals.

Used when the selected method stops being eligible for the cart as it is NOW (weight change, last physical line removed) — leaving it selected showed a zero-cost method the cart had outgrown and let checkout proceed to an inevitable conversion failure.

Collects all storage file UUIDs associated with a single product.

Collects all storage file UUIDs for a list of product UUIDs.

Marks import as completed.

Converts a cart to a Billing.Order.

Takes an active cart with items and creates an Order with:

• All cart items as line_items
• Shipping as additional line item (if selected)
• Billing profile snapshot (from profile_uuid or direct billing_data)
• Cart marked as "converted"

For guest checkout (no user_uuid on cart):

• Creates a guest user via Auth.create_guest_user/1
• Guest user has confirmed_at = nil until email verification
• Sends confirmation email automatically
• Order remains in "pending" status

Options

• billing_profile_uuid: uuid - Use existing billing profile (for logged-in users)
• billing_data: map - Use direct billing data (for guest checkout)

Returns

• {:ok, order} - Order created successfully
• {:error, :cart_not_active} - Cart is not active
• {:error, :cart_empty} - Cart has no items
• {:error, :no_shipping_method} - No shipping method selected
• {:error, :email_already_registered} - Guest email belongs to confirmed user

Creates a new import log entry.

Creates a new product.

Automatically normalizes metadata (price modifiers, option values) before saving to ensure consistent storage format.

Creates a new shipping method.

Tailwind source roots contributed to the host's CSS build.

Both README.md and AGENTS.md claimed this was implemented; it was not, and the use PhoenixKit.Module default returns []. The consequence was invisible rather than loud: core's :phoenix_kit_css_sources compiler collects this from every discovered module and writes assets/css/_phoenix_kit_sources.css, so with shop contributing nothing, Tailwind purged every class used only by this module's storefront and admin templates from the host build.

It stayed hidden because the compiler only warns when the TOTAL source list is empty — any other installed module masked the absence.

Resolves the currency a PERSISTED record was denominated in.

Order and cart pages used to load today's default currency, so changing the shop currency silently relabeled every historical order's amounts. Given the code stored on the record, this returns its Currency struct; an unresolvable code returns nil — callers then show the bare code rather than borrowing today's default symbol for an amount it does not describe.

Returns {:created, config} if a new config was created, or :exists if configs already exist.

Ensures a category has a featured_product_uuid set.

If the category has no image_uuid and no featured_product_uuid, auto-detects the first active product with an image and saves it. Returns the (possibly updated) category with :featured_product preloaded.

Ensures a default Prom.ua import config exists. Creates one if no config with name "prom_ua_default" is found.

Expires old guest carts.

Marks import as failed.

Marks abandoned carts (no activity for X days).

Merges guest cart into user cart after login. Accepts a user struct or user_uuid (string).

Merges import attributes into an existing product.

A feed states what it knows; it cannot state what it does not know. The importers always emit the full attribute set, so a column the file omits arrives as a blank — and treating that blank as an instruction meant a routine second import DELETED data the file never mentioned:

• a blank Body (HTML) cell erased that product's description in every language, not merely the imported one;
• a feed with no image columns cleared the product's images and vendor;
• metadata was rebuilt from the feed, dropping the admin's option price modifiers, image mappings, price-display unit and custom keys.

So a blank incoming value leaves the stored one alone, localized maps merge per language, and metadata merges per key. Anything the feed does carry still wins — including a value that clears a single translation.

Examples

iex> merge_localized_attrs(%Product{title: %{"en-US" => "Old"}}, %{title: %{"es-ES" => "Nuevo"}})
%{title: %{"en-US" => "Old", "es-ES" => "Nuevo"}}

Merges built-in default filters missing from a saved filter config.

Configs saved before a built-in filter existed (e.g. search) never gain it on their own; this merges the absent built-ins in as disabled so admins can discover and enable them from the settings page without changing storefront behavior until they do.

Missing filters are positioned below every saved filter's "position" (preserving their relative order from default_storefront_filters/0) rather than reusing their default position outright — a saved config predating the new filter can already hold that same position number, and a tie would fall back to list order once enabled, silently overriding the intended placement (e.g. search no longer sorting first).

Notification types this module contributes (duck-typed, discovered by core's Notifications.Types).

Two audiences, deliberately separate sub-types so a shop operator can mute the order firehose without silencing their own receipts — and so a customer's confirmation is never governed by an admin-facing preference.

⚠️ The actions registered here are the NOTIFY actions. The audit trail uses different action strings on purpose: Activity.log/1 auto-derives notifications from registered actions, so an audit row written with a notify action would deliver a second, duplicate notification.

@spec preview_checkout_totals(
  PhoenixKitEcommerce.Cart.t(),
  keyword()
) :: {:ok, PhoenixKitEcommerce.Cart.t()} | {:error, term()}

Applies the checkout billing country to the cart and recalculates totals, WITHOUT converting anything.

The review step must show the amount the customer is about to be charged. The cart page deliberately leaves shipping_country nil ("set at checkout"), and tax is zero for a nil-country cart — so before this existed, a customer reviewed a pre-tax total and convert_cart_to_order/2 then applied the country, recalculated, and charged more. Cart 100.00 + shipping 10.00 at 20%: review said 110.00, the order said 130.00.

That gap opened the moment tax started working at all, so it ships with the same change. Runs the identical country resolution and recalculation the conversion uses, so the two cannot disagree.

Takes the same :billing_profile_uuid / :billing_data options as convert_cart_to_order/2. Returns the reloaded cart.

Returns a map of category_uuid => product_count for all categories.

Checks if a product slug exists for a language.

Useful for validation during translation editing.

Examples

iex> Shop.product_slug_exists?("maceta-geometrica", "es-ES")
true

iex> Shop.product_slug_exists?("maceta-geometrica", "es-ES", exclude_uuid: "some-uuid")
false

@spec product_url(PhoenixKitEcommerce.Product.t(), String.t()) :: String.t()

Generates a localized URL for a product.

Returns the correct locale-prefixed URL with translated slug. The URL respects the PhoenixKit URL prefix configuration.

Parameters

• product - The Product struct
• language - Language code (e.g., "en-US", "ru", "es-ES")

Examples

iex> Shop.product_url(product, "es-ES")
"/es/shop/product/maceta-geometrica"

iex> Shop.product_url(product, "ru")
"/ru/shop/product/geometricheskoe-kashpo"

iex> Shop.product_url(product, "en")
"/shop/product/geometric-planter"  # Default language - no prefix

@spec rekey_cart_session(String.t(), String.t()) :: :ok | :error

Moves a live guest cart from one shop-session id to another.

Used by the pre-signing cookie migration. The plug mints a FRESH id and re-keys the cart onto it, rather than re-signing whatever the client presented — re-signing a replayed value would have turned it into a fully trusted session on the very next request, which is the capability the signing exists to prevent.

Scoped to active, unclaimed carts for the same reason session_has_cart?/1 is: a converted or account-owned cart must never be re-keyed by an unsigned cookie. Returns :ok when exactly one cart moved.

Removes item from cart.

@spec session_has_cart?(String.t() | any()) :: boolean()

Whether any cart exists for this shop session id.

Used by PhoenixKitEcommerce.Web.Plugs.ShopSession to decide whether an unsigned, pre-migration cookie names a real session worth adopting. Existence only — no cart is loaded and nothing is authorized by this.

Sets payment option for cart.

Sets shipping method for cart.

Sets the shipping country for the cart.

Marks import as started.

Returns translation helpers module for direct access.

Examples

iex> Shop.translations()
PhoenixKitEcommerce.Translations

Updates item quantity in cart.

Updates a category.

Updates translation for a specific language on a category.

Parameters

• category - The category struct
• language - Language code (e.g., "es-ES")
• attrs - Translation attributes: name, slug, description

Examples

iex> Shop.update_category_translation(category, "es-ES", %{
...>   "name" => "Jarrones y Macetas",
...>   "slug" => "jarrones-macetas"
...> })
{:ok, %Category{}}

Updates an import config.

Updates an import log.

Updates import progress.

Updates a product.

Automatically normalizes metadata (price modifiers, option values) before saving to ensure consistent storage format.

Updates translation for a specific language on a product.

Parameters

• product - The product struct
• language - Language code (e.g., "es-ES")
• attrs - Translation attributes: title, slug, description, body_html, seo_title, seo_description

Examples

iex> Shop.update_product_translation(product, "es-ES", %{
...>   "title" => "Maceta Geométrica",
...>   "slug" => "maceta-geometrica"
...> })
{:ok, %Product{}}

Updates a shipping method.

Saves storefront filter configuration.

Creates or updates a product by slug.

Uses explicit find-or-create pattern with proper localized field merging. After V47 migration, slug is a JSONB map (e.g., %{"en-US" => "my-slug"}), so ON CONFLICT doesn't work correctly - this function handles the lookup manually.

Returns {:ok, product, action} where action is :inserted or :updated.

Parameters

• attrs - Product attributes including localized fields as maps

Examples

# Create new product
iex> upsert_product(%{title: %{"en-US" => "Planter"}, slug: %{"en-US" => "planter"}, price: 10})
{:ok, %Product{}, :inserted}

# Update existing product (found by slug)
iex> upsert_product(%{title: %{"en-US" => "Planter V2"}, slug: %{"en-US" => "planter"}, price: 15})
{:ok, %Product{}, :updated}

# Add translation to existing product
iex> upsert_product(%{title: %{"es-ES" => "Maceta"}, slug: %{"es-ES" => "maceta", "en-US" => "planter"}, price: 10})
{:ok, %Product{title: %{"en-US" => "Planter", "es-ES" => "Maceta"}}, :updated}

Validates selected_specs against product's option schema.

Checks:

• All spec keys exist in the option schema
• All spec values are in allowed values list (if defined)
• All required options have values

Returns

• :ok - All specs are valid
• {:error, :unknown_option_key, key} - Key not in schema
• {:error, :invalid_option_value, %{key: key, value: value, allowed: list}} - Value not allowed
• {:error, :missing_required_option, key} - Required option not provided

Examples

iex> validate_selected_specs(product, %{"material" => "PETG"})
:ok

iex> validate_selected_specs(product, %{"material" => "Unobtainium"})
{:error, :invalid_option_value, %{key: "material", value: "Unobtainium", allowed: ["PLA", "PETG"]}}
