Attributtify — Rule-Based Combination Builder for PrestaShop 8

Attributtify replaces PrestaShop's default cartesian combination generator with a rule-based pricing engine. Instead of generating every attribute combination and editing prices row by row, you define pricing rules with conditions — the module generates exactly the combinations you need with correct prices applied automatically.

Built for PrestaShop 8.x products with complex combination pricing: configurable pricing per attribute group, fixed prices, percentage impacts, condition-based exclusions — without manually touching 100+ combination rows.

Features

• Rule engine — define conditions (attribute group → values) instead of editing each combination by hand
• Fixed prices — most-specific matching rule sets the exact combination price automatically
• Impact pricing — add fixed dollar or percentage amounts on top of a base price; all matching impact rules are summed
• Condition groups — AND-chains with multiple OR blocks; fine-grained control over which combinations get which price
• Excludes & Applies-to — restrict or skip combinations by attribute value
• Preview before generating — inspect the full combination list before writing to the database
• Anti-amplification guard — prevents the same impact rule from applying more than once to a combination
• Custom reference patterns — {product_ref}, {attrs}, {n} tokens for auto-generated SKUs
• Zero configuration — the panel appears automatically inside the Combinations tab on every product page

The problem it solves

Standard PrestaShop combination generation is cartesian: pick all attribute groups, generate all combinations, then manually edit each price. For products with complex pricing — base model × color × accessory kit × subscription tier — this means editing hundreds of rows by hand.

Example — a configurable product with base models, options and subscription tiers:

Combination	Price
Widget Basic White	$200
Widget Basic Black	$200
Widget Pro White	$450
Widget Pro Black	$450
Widget Pro White + Accessory Kit S	$450 + $40
Widget Pro White + Accessory Kit S + Support 1 Year	$450 + $40 + $90
...	...

With Attributtify you define ~5 rules instead of editing 80+ combinations.

How it works

Rules table

Each row in the Attributtify table is a pricing rule with three tabs:

Conditions — AND-chain of (Attribute Group → Values) pairs. All pairs must match for the rule to apply. Multiple OR blocks mean any block can match.

Applies to — restrict an impact rule to combinations that already contain specific attribute pairs. Leave empty to apply to all.

Excludes — skip combinations that contain any of the listed attribute values.

Price types

Type	Behavior
Fixed $	Most-specific matching rule sets the exact combination price. Specificity = number of condition pairs × 10000 − total values.
Impact $	Dollar amount added to the base price. All matching impact rules are summed.
Impact %	Percentage of the base price added as impact.

Generation logic

1. Phase 1 — Fixed rules define the base combination tuples and their prices.
2. Phase 2 — Impact rules expand each tuple, adding price deltas. Anti-amplification guard prevents the same impact from applying multiple times to the same combination.
3. Fallback — If no fixed rules exist, the cartesian product of impact rules (where Applies to is empty) is used as the base.

Interface

The panel appears inside the Combinations tab of the product page, above the standard combination generator.

Toolbar

Button	Action
Save	Persist the current rule table to the database (stored as JSON in ps_configuration).
Load	Discard unsaved changes and reload the last saved config. Prompts if there are unsaved changes.
Preview & Generate	Save → compute combinations server-side → show a preview table → confirm → create/update combinations in PrestaShop.

Settings strip

• Ask for confirmation before deleting rows and blocks — enables confirm dialogs for destructive actions. Persisted in localStorage.
• Auto-generate references (ATTY-{attrs}) when no custom ref is set — when unchecked, combinations without a custom reference pattern are created with an empty reference. Persisted in localStorage.

Reference patterns

Custom reference field supports tokens:

Token	Resolves to
{attrs}	Hyphen-joined attribute value IDs
{n}	Sequential combination number
{product_ref}	Product's base reference

Example: WK-{product_ref}-{n} → WK-SKU001-1, WK-SKU001-2, …

---

Installation

1. Upload the ps_attributtify folder to /modules/.
2. Install via Modules → Module Manager.
3. No configuration needed — the panel appears automatically on all product pages that have the Combinations tab.

Requirements

• PrestaShop 8.0.0 or higher
• PHP 7.4+

---

Uninstall

Uninstalling removes all saved rule configurations (ATTRIBUTTIFY_PRODUCT_* keys from ps_configuration). Generated combinations are not affected.

AJAX actions

Action	Description
saveConfig	Saves serialised rules JSON for the product.
loadConfig	Returns saved rules JSON for the product.
preview	Computes combinations without writing to DB. Returns preview array.
generate	Computes and creates/updates combinations in PrestaShop.

Data storage

Rules are stored as JSON in ps_configuration under the key ATTRIBUTTIFY_PRODUCT_{id_product}.

Rule schema:

{
  "price_type": "fixed | impact | impact_pct",
  "price_value": 1234.56,
  "qty": 1,
  "reference": "WK-{n}",
  "weight": 0,
  "condition_groups": [
    {
      "pairs": [

      ]
    }
  ],
  "applies_to": [],
  "excludes": []
