Problem with text attribute and update_quantity()

[jdill2d]

Zen Cart 1.3.8a

I'm trying to update the qty of products in the shopping cart that contain attributes including a text attribute. After the update occurs, all attributes remain but the text attribute disappears. How do I pass the correct $attributes parameter in the update_quantity function to make this work.

My simplified observer class class.test.php

<?php
class test extends base {

function test() {
$_SESSION['cart']->attach($this,array('NOTIFIER_CART_ADD_CART_END', NOTIFIER_CART_REMOVE_END'));
}

function update(&$class, $eventID) {
$products = $_SESSION['cart']->get_products();
for ($i=0, $n=sizeof($products); $i<$n; $i++) {
$_SESSION['cart']->update_quantity($products[$i] ['id'],5,$products[$i]['attributes']);
}
}
}
?>

I finally figured this out (I'm a newby at php programming and wasn't familiar with associative arrays).

$products[$i]['attributes'] does not include the attribute values for text attributes. You have to get text values out of the $products[$i]['attributes_values'] array. I solved this by generating a new attributes array to pass to update_quantity() which contains the text attribute values. You have to look at each array element to see if it's a text value then update the $key and $value in the new array. Here's the simplified code:

function update(&$class, $eventID) {
$total = $_SESSION['cart']->count_contents();
$products = $_SESSION['cart']->get_products();

for ($i=0, $n=sizeof($products); $i<$n; $i++) {
foreach ($products[$i]['attributes'] as $key => $value){
if ($value == PRODUCTS_OPTIONS_VALUES_TEXT_ID) {
$text = $products[$i]['attributes_values'][$key];
$new_key = TEXT_PREFIX . $key;
$products[$i]['new_attributes'][$new_key]=$text;
} else {
$products[$i]['new_attributes'][$key]=$value;
}
}

}

for ($i=0, $n=sizeof($products); $i<$n; $i++) {
$_SESSION['cart']->update_quantity($products[$i]['id'],5,$products[$i]['new_attributes']);
}
}
