В Magento есть функция, в которой вы можете определить порядок подсчета итогов, указав до и после которого итоги должны выполняться.
Я добавил пользовательский итог, и если я добавлю следующие строки в config.xml, сортировка будет неправильной. Неверное значение: tax_shipping
предшествует раньше shipping
.
Это приводит к тому, что налог на стоимость доставки будет добавлен дважды.
Но это нарушает условие
tax_shipping
after: shipping
Мое предположение: В полном наборе правил должно быть какое-то противоречие. Но как мне его найти?
Это единственное правило, которое я добавляю. Без этого правила tax_shipping
сортируется после shipping
.
<shippingprotectiontax>
<class>n98_shippingprotection/quote_address_total_shippingprotectionTax</class>
<after>subtotal,discount,shipping,tax</after>
<before>grand_total</before>
</shippingprotectiontax>
Ниже я вставляю отсортированный массив, который возвращается вызовом usort в Mage_Sales_Model_Quote_Address_Total_Collector::_getSortedCollectorCodes()
Для тех, у кого нет установки Magento, код выглядит так:
/**
* uasort callback function
*
* @param array $a
* @param array $b
* @return int
*/
protected function _compareTotals($a, $b)
{
$aCode = $a['_code'];
$bCode = $b['_code'];
if (in_array($aCode, $b['after']) || in_array($bCode, $a['before'])) {
$res = -1;
} elseif (in_array($bCode, $a['after']) || in_array($aCode, $b['before'])) {
$res = 1;
} else {
$res = 0;
}
return $res;
}
protected function _getSortedCollectorCodes()
{
...
uasort($configArray, array($this, '_compareTotals'));
Mage::log('Sorted:');
// this produces the output below
$loginfo = "";
foreach($configArray as $code=>$data) {
$loginfo .= "$code\n";
$loginfo .= "after: ".implode(',',$data['after'])."\n";
$loginfo .= "before: ".implode(',',$data['before'])."\n";
$loginfo .= "\n";
}
Mage::log($loginfo);
...

EDIT:
После ответа Vinai я добавил еще отладочный код
$fp = fopen('/tmp/dotfile','w');
fwrite($fp,"digraph TotalOrder\n");
fwrite($fp,"{\n");
foreach($configArray as $code=>$data) {
$_code = $data['_code'];
foreach($data['before'] as $beforeCode) {
fwrite($fp,"$beforeCode -> $_code;\n");
}
foreach($data['after'] as $afterCode) {
fwrite($fp,"$_code -> $afterCode;\n");
}
}
fwrite($fp,"}\n");
fclose($fp);
И визуализировал это с помощью графика: dot -Tpng dotfile > viz.png
. Это результат первой попытки. Вызывается после сортировки.

EDIT2:
Я думаю, что это довольно бесполезно.
Итак, я сделал визуализацию массива перед объединением записей после / до. (сразу после $configArray = $this->_modelsConfig;
)
Это без моей shippingprotectiontax
записи:
![enter image description here](https://i.stack.imgur.com/hXHxT.png)
Вот с моей shippingprotectiontax
записью:
![enter image description here](https://i.stack.imgur.com/uiAjb.png)
Я не вижу четких противоречий.
