Weight Filter via URL Parameters

The Weight Filter via URL Parameters plugin enables filtering of product listings by weight via URL parameters. Customers and external systems can restrict product listings to a specific weight range by passing min-weight and max-weight directly in the URL. The plugin is ready to use immediately after activation and requires no further configuration.

How It Works

The plugin registers an event subscriber on the ProductListingCriteriaEvent. Every time a product listing is loaded, the handler checks the incoming URL parameters. If min-weight or max-weight are set, a RangeFilter on the product.weight field is added to the listing criteria. Filtering takes place server-side before the database query is executed.

URL Parameter	Description
min-weight	Minimum weight in kilograms (inclusive)
max-weight	Maximum weight in kilograms (inclusive)

Both parameters can be used independently or combined. If only max-weight is set, the minimum value is automatically set to 0.
