Carbon footprint module for products and orders

v1.7.22026/10/04

Revision of 1.7.1 (LFR). Tested on PrestaShop 8.2.8 and 9.2.0 , with and without rkrmixmatchbox 2.23.0 , and the update 1.1.9 → 1.7.1 → 1.7.2.

Serious flaws in version 1.7.1 :

• The product data sheet would give a fatal error (blank page) as soon as the product had a footprint or was a box: the bridge log would receive a non-existent cart.
• The selftest feature used to return the contents of ANY shopping cart by its number, with a token that was the same for all visitors and published on the page. Now it only exists in debug mode and only for the user's own shopping cart.
• The ?rkrcf_diag=1 panel could be opened by any visitor (PrestaShop and PHP version, cart configuration and contents). Only in debug mode.
• The log used to write to the module's folder on each page , with one file per cart that was never deleted (and in Nginx, readable from outside). Now it only writes in debug mode and to the kernel's var/logs . Additionally:
• Without rkrmixmatchbox installed, its table is no longer consulted, nor is it written to error_log on each render.
• The line hook ( displayProductPriceBlock ) and the menu are no longer repaired on every request: upgrade-1.7.2.php does it once (there was no upgrade from 1.1.9 to 1.7.1 ).
• The Addons rules that version 1.7.x had lost are clean again: Context::getContext() , Tab::getIdFromClassName , nofilter (the data of the boxes and the order lines go in a data-json attribute), HTML within the PHP (to templates), PHPStan and formatting.
• Outside the package: logs/ , config_es.xml and a translation catalog in the translations/ root that PrestaShop does not read.
• The annual panel and desktop amount is displayed in currency format ("€0.30").
• Pending: footprint and weight figures also appear with a decimal point in Spanish ("4.34 kg CO₂e").

v1.1.92026/09/30

Full revision of version 1.1.8 , tested on PrestaShop 8.2.8 , 9.0.0 and 9.1.5.

Failures that affected money or data:

• The compensation paid was recorded as €0. The customer paid the compensation line, but the order showed a zero amount: the annual panel, the CSV export, and the seal all said "compensated" with no amount.
• With the amount correctly registered, the stamp broke the page in PrestaShop 9 (confirmation, customer account, order in the back-office and PDF invoice): it used a function that PrestaShop 9 no longer has.
• Saving a product's footprint would leave it "without a footprint". From the "Footprint by product" panel, or by choosing "Module default" on the product page, the product would disappear from the page, listings, and shopping cart.
• Changing the compensation tax didn't affect the service product : it was charged differently than advertised (17% less when switching to 21% VAT). Now it's applied when saving, and the calculation uses the actual tax.
• National orders at 0 km. The centroid of Spain coincides with the default origin (Madrid) and national transport did not add anything; now it uses the configured average distance (350 km by default).
• Saving the Distances tab left the countries without coordinates at (0,0) —Gulf of Guinea—.
• In multi-currency transactions, the amount was displayed without conversion.
• A shopping cart divided into several orders had its footprint counted multiple times. Other arrangements:
• The service product is created as a virtual product (previously requiring shipping) and is removed upon uninstallation; upon reinstallation, it is no longer duplicated. The upgrade marks as virtual the products of stores that already had them.
• The compensation cart prices are automatically cleared when validating orders and with "Purge old carts".
• Only an employee with editing permissions can save or purge on the panel.
• Geocoding does not repeat the query to Nominatim for a postal code that it did not find, and it also works without allow_url_fopen .
• The compensation switch no longer deselects itself when another module prints warnings in debug mode.
• Original texts in English with a complete Spanish catalog (445 chains): the English store no longer displays the panel and shopping cart in Spanish. The back-office menu appears in each employee's language.
• Addons validator structure and rules: index.php in each folder, .htaccess , LICENSE.txt , no nofilter , no removed functions, PHPStan and PHP CS Fixer without warnings.
