Product Warning

eTechFlow Product Warning adds per-product and per-category coloured warning banners to your Magento 2 and Adobe Commerce product detail pages. Create notices in the admin — "Ships from a remote warehouse", "Repair case only", "Backorder — 7 day lead time", or any custom message — assign them to specific products or whole categories, and the storefront auto-renders them above the price on every matching product. It is theme-agnostic (Hyvä, Luma, Mage-OS and custom themes), needs no template overrides, adds no external service, and renders nothing until you create a warning, so installing it never changes your storefront.

Warnings can be pinned to individual SKUs or to a whole category — every product in that category (including products added later) inherits the banner automatically. When several warnings match a product they render in a vertical stack ordered by sort order, and duplicates are shown once. Each banner uses a custom hex colour for its tint and left border and can be toggled active or inactive without deletion. The banner block is scoped (.epw-* CSS), server-rendered with zero JavaScript, and respects Full Page Cache. A WarningResolver PHP API is available for rendering warnings in custom locations such as listing pages, the cart, or transactional emails.
