Version 1.1.0

• Conditional payment-method visibility engine for PrestaShop — control which payment gateways appear at checkout using named policies, each with its own scoped AND/OR condition tree and a dedicated set of per-module rules (SHOW or HIDE). Compatible with PrestaShop 1.7.x, 8.x and 9.x from a single codebase with a dedicated compatibility layer.
• Visual condition builder with nested logic — build checkout rules without code using a premium back-office interface:
  • 12 live evaluation fields: cart total (tax incl.), products total, product quantity in cart, currency, delivery country, delivery zone, customer group, carrier, customer logged-in status, product in cart, category in cart and manufacturer in cart.
  • 9 comparison operators: equals, not equals, greater than, greater or equal, less than, less or equal, in list, not in list and between range.
  • Unlimited nested AND/OR groups at policy level and per individual payment rule.
  • One-click quick presets (guest-only, business-to-business group, minimum cart value and more) plus server-stored presets and a raw JSON editor for advanced configurations.
  • searchTool autocomplete for products, categories, manufacturers and customer groups in condition fields — with reliable binding on dynamically created builder rows.
• Five merge strategies per policy — resolve conflicts when multiple rules target the same payment module:
  • Deny wins — any matching HIDE rule hides the payment method.
  • Allow wins — any matching SHOW rule shows the payment method.
  • Priority cascade — the first matching rule by priority decides the outcome.
  • Weighted score — SHOW adds +1, HIDE subtracts −1; net score determines visibility.
  • Unanimous SHOW — all matching rules must be SHOW for the payment to appear.
• Per-gateway payment rules — one rule card per installed payment module inside each policy: set visibility (SHOW/HIDE), evaluation priority, display position, optional active date range, and a multilingual unavailable message with a PrestaShop-style language selector (flag and ISO code per shop language).
• Unavailable payment messages at checkout — global setting lets you either remove hidden methods from the payment list entirely, or keep them visible as disabled options with your custom explanation inline on the payment step (not a separate alert block). Messages are stored per rule and per language in a dedicated translation table.
• Checkout filtering and order validation guard — payment options are filtered through the native actionFilterPaymentOptions hook on PrestaShop 8.1 and above, with a compatibility fallback on earlier versions. Rules are enforced again at order validation; if a customer reaches a hidden gateway validation URL, the order is blocked before creation. A visibility snapshot and payment module name are stored on the order record for back-office traceability.
• Enterprise back-office dashboard and analytics — KPI cards, configurable reporting period (30, 90, 180 or 365 days), Chart.js trend charts (daily, weekly and monthly views), stacked bar chart of rule evaluations per payment module, donut chart with global totals, and a recent activity feed linked to the audit log.
• Checkout simulator — test policies against real shop data without placing orders: search and select an active shopping cart, optionally attach a customer, run the evaluation engine and review a detailed result table showing final visibility per payment module, matched policies and unavailable messages. Clear three-step flow with field descriptions and browsable cart list with load-more pagination.
• Policy management workflow — full CRUD for payment visibility policies with drag-and-drop ordering, stop on first match option, policy-level default visibility, merge strategy override, and quick enable/disable:
  • Duplicate policy — one-click copy of conditions, rules, merge strategy and multilingual messages as an inactive policy; available from the HelperList row action, policy editor toolbar and module configuration preview (with correct initProcess() handling for PrestaShop list actions).
  • JSON import and export — download any policy as a portable file or upload to create a new policy on the same shop or a staging environment; every import, export and duplicate action is recorded in the audit log.
  • Native PrestaShop active toggle on the policies HelperList (bool / status column) and in the module configuration preview, with a custom processStatus() redirect so toggling from the module page returns correctly without PHP notices.
• Payment policies HelperList enhancements — payment-module colour pills, rules and conditions summary columns, merge strategy and stop-on-match indicators, updated date column, export shortcut, and a premium policy editor toolbar (title, meta pills, Export, New policy, Simulator, Audit log and Module settings quick actions).
• Full audit log — dedicated admin controller under the Payments menu records visibility evaluations, order validation blocks, policy create/update/delete, imports, exports, duplicates, settings changes and simulation runs. Filter by date, event type and payment module; preview full detail payloads; export to CSV.
• Six module configuration tabs plus native admin menus — Dashboard, Policies, Settings, Simulator, Audit log and Updates inside module configuration; Payment policies and Audit log also available as standalone entries under the PrestaShop Payments menu.
• Back-office UX and layout refinements:
  • Premium wallet-style stat cards, condition builder live preview and full-width form groups for the condition builder and payment rules editor (labels hidden, content column spans full panel width).
  • Policy rule cards with improved multilanguage unavailable-message input (input-group with language dropdown append); card overflow set to visible so language selectors are never clipped.
  • Policies list panel overflow corrected so dropdown menus are not cut off at the panel edge.
  • Dashboard analytics parameters and charts integrated inside the main panel frame; simulator cart lookup renamed and documented for clarity.
• Reliability and compatibility fixes:
  • Fixed policy condition Products total always evaluating as zero — cart context now includes products total (tax incl.) from Cart::ONLY_PRODUCTS.
  • Fixed checkout fatal error when building evaluation context — Customer::getStats() is now called on the customer instance, not statically.
  • Fixed simulator and searchTool AJAX endpoints — correct AdminModules URL (index.php + token via getAdminLink) and customer searchType handler; resolves HTTP 308 on autocomplete requests.
  • Fixed searchTool autocomplete formatItem returning an object instead of a string (preventing value.replace JavaScript errors).
  • Fixed searchTool binding on the policy editor — autocomplete.js loaded via initTool() before the binder script, with retry binding for dynamically created condition fields.
  • Removed broken ensureSchema() on fresh install (invalid SHOW TABLES … LIMIT 1 on MariaDB); schema is applied from install.sql only. Audit log writes use correct column names.
  • Back office refactored to standard PrestaShop HelperForm, HelperView and Smarty preview templates for settings, simulator, import and policy editor panels.
• Database layer — custom tables for policies, rules, rule language messages, condition presets and audit log; optional payment sort positions per shop; order table columns for visibility snapshot and selected payment module name.
• MyPresta updates tab — built-in module version check and update notifications from MyPresta.eu.
