Prestashop Module Override May 2026

<?php // override/modules/customshipping/classes/CustomShippingCalculator.php class CustomShippingCalculatorOverride extends CustomShippingCalculator

/override/modules/customshipping/classes/CustomShippingCalculator.php Your override must extend the original class and use the same namespace. prestashop module override

// Original logic would run if we called parent $originalCost = parent::calculateCost($products); Use overrides sparingly

Use overrides sparingly, document them religiously, and always ask: “Could I achieve this with a hook or a custom module instead?” document them religiously

When used correctly, overrides will save you from module vendor lock-in and let you bend PrestaShop to your exact business needs – without losing the ability to update. Have a tricky module override scenario? Share it in the comments below!
