How can I get all the simple products associated with a configurable product? I found how to do the opposite (get a product configurable from a simple product) but that's not what I need.
I want to show how many units I have in stock for the selected product (configurable attribute). My initial idea is to print all quantities of stock and control the display with jQuery. Any idea?
use the following script in
app/design/frontend/default/[your theme]/template/catalog/product/view/type/options/configurable.phtml
Inside the script:
spConfig.getIdOfSelectedProduct = function () {
var existingProducts = new Object();
for (var i = this.settings.length - 1; i >= 0; i--) {
var selected = this.settings[i].options[this.settings[i].selectedIndex];
if (selected.config) {
for (var iproducts = 0; iproducts < selected.config.products.length; iproducts++) {
var usedAsKey = selected.config.products[iproducts] + "";
if (existingProducts[usedAsKey] == undefined) {
existingProducts[usedAsKey] = 1;
} else {
existingProducts[usedAsKey] = existingProducts[usedAsKey] + 1;
}
}
}
}
for (var keyValue in existingProducts) {
for (var keyValueInner in existingProducts) {
if (Number(existingProducts[keyValueInner]) < Number(existingProducts[keyValue])) {
delete existingProducts[keyValueInner];
}
}
}
var sizeOfExistingProducts = 0;
var currentSimpleProductId = "";
for (var keyValue in existingProducts) {
currentSimpleProductId = keyValue;
sizeOfExistingProducts = sizeOfExistingProducts + 1
}
if (sizeOfExistingProducts == 1) {
alert("Selected product is: " + currentSimpleProductId)
}
}
Now add onchange event to your dropdown in same page :
onchange = "spConfig.getIdOfSelectedProduct()"
