hi !
here is a working solution (show unit product price without tax in product list) for prestashop 1.7.6.9 with classic theme (may work with others versions)
edit themes/classic/templates/catalog/_partials/miniatures/product.tpl
around line 70 after :
<span class="sr-only">{l s='Price' d='Shop.Theme.Catalog'}</span>
<span itemprop="price" class="price">{$product.price} HT</span>
add :
{if $product.unit_price_full != ""}
{math assign="result" equation="rprice / ratio" rprice=$product.price_tax_exc ratio=$product.unit_price_ratio}
<br><span class="unit_price">(soit {$result|string_format:"%.2f"} € HT {$product.unity})</span>
{/if}
result in product list is (in euros / french) :
Sable en sac de 2kg
20,60 € HT
(soit 10,30 € HT le kilo)
You have to add some custom CSS to expand the miniature look
in themes/classic/assets/css/custom.css
add :
/* PRODUCTS LIST */
.products .thumbnail-container, .featured-products .thumbnail-container, .product-accessories .thumbnail-container, .product-miniature .thumbnail-container {height:338px;}
.products .thumbnail-container .product-thumbnail, .featured-products .thumbnail-container .product-thumbnail, .product-accessories .thumbnail-container .product-thumbnail, .product-miniature .thumbnail-container .product-thumbnail {height:calc(100% - 90px)}
.products .product-description, .featured-products .product-description, .product-accessories .product-description, .product-miniature .product-description {height:90px;}
.products .highlighted-informations, .featured-products .highlighted-informations, .product-accessories .highlighted-informations, .product-miniature .highlighted-informations {height : 4.125rem}
Enjoy !
