pagina prodotto il prezzo non cambia in base alla quantità e ai prezzi specifici

mighi · February 3, 2014

Ciao a tutti, sto facendo un sito con Prestashop 1.5.6.1

Ho un problema che riguarda i prezzi specifici, in sostanza ho un prodotto che ad esempio costa 10€.

A questo prodotto ho impostato diversi attributi ad esempio colore e tipo di stampa, impostando un prezzo solo a quest'ultima.

Avendo la necessità di fare degli sconti in base alla quantità scelta, ho impostato nei prezzi specifici degli sconti a tutte le possibili combinazioni.

Tutto funziona perfettamente ad eccezione del fatto che se vado nella pagina del prodotto nel FO i prezzi cambiano solo in base alla combinazione, io vorrei che cambiasse anche in base alla quantità e quindi che venisse mostrato il prezzo con una diminuzione se ad esempio scelgo di prendere 50 o 100 prodotti.

Qualcuno ha già avuto a che fare con un problema del genere???

in giro ho trovato questo ma non mi funziona :

Come al solito sul forum italiano tutto tace...

Se a qualcuno interesso ho risolto sta cosa del cambio di prezzo in base alla quantià in product.tpl, basta aggiungere questo codice alla fine del file product.js (url_tema/js/product.js)

$(document).ready(function(){
$("#quantity_wanted").on("input",function(){

Sono molto vicino a far cambiare il prezzo anche in base ai prezzi specifici, devo solo fare le query...

Grazie per lo script

Ho seguito le istruzioni, ma non succede niente...
