我正在使用脚本来更新价格。到目前为止，它从CSV获取数据，并使用它在数据库中查找并使用该行的CSV信息更新产品。
我遇到的问题是CSV中的SKU与Magento中的SKU不完全匹配。例如，在CSV中可能有1234但是在magento中，需要使用此行中的信息进行更新的产品将是001234_01和001234_02以及001234_03等等
所以我添加了一个LIKE搜索来获取Magento的所有结果，就像CSV中该行的SKU一样。
问题是它只找到一个更新它然后移动到下一行。因此它会更新001234_01，但我需要它来更新001234_02和001234_03，然后再转到下一行。
我想我需要将_updatePrices调整为foreach，但我似乎无法让它工作。

答案 0 :(得分：1)
好的，您的函数_checkIfSkuExists($sku)应该返回不计行，而是返回行：
function _checkIfSkuExists($sku){
$connection = _getConnection('core_read');
$sql = "SELECT * FROM " . _getTableName('catalog_product_entity') . " WHERE sku LIKE '%$sku%'";
// I think you can try $conn->fetchAll();
return $connection->fetchAll($sql, array($sku));
// print_r this - it will be an array (empty or not)
}
// in each row's data there's a record (or row) ID
function _updatePrices($data, $row){
$connection = _getConnection('core_write');
$sku = $data[0];
$newPrice = $data[4];
$specialPrice = $data[6];
$status = $data[10];
// here - you don't need to find `entity_id`, you already have it in $row
//$productId = _getIdFromSku($sku);
$productId = $row['entity_id'];
$attributeId = _getAttributeId();
// all your code remains the same
// ....
} // function _updatePrices ends
// ....
// Here comes your code after UTILITY FUNCTIONS:
$csv = new Varien_File_Csv();
$data = $csv->getData('price-update/PRDAH014.csv'); //path to csv
array_shift($data);
$message = '';
$count = 1;
foreach($data as $_data){
// insted of checking if number of rows that
// match your LIKE query is greater than zero
// if(_checkIfSkuExists($_data[0])){
// you get rows themselves that match your LIKE query
$skuRows = _checkIfSkuExists($_data[0]);
if(0 < sizeof($skuRows)){
// okay you have records, let's iterate through them
foreach ($skuRows as $row) {
try{
// modify your _updatePrices so as to use record ID from $row and CSV data from $data both
_updatePrices($_data, $row);
} catch(Exception $e){
// exception warning

我对Magento并不熟悉，但我认为algorythm是这样的。
