Question

我正在使用脚本从CSV更新Magento中的产品价格。

目前，CSV中的SKU与Magento中的SKU完全不匹配。例如，CSV中的一个可能是33456，但在Magento中，它将是003456_01或003456_02。所以我需要脚本只匹配SKU的中间部分，所以如果在Magento中的SKU之后有00或_01，那么在移动到下一行之前它仍然会更新所有匹配该SKU的内容

$mageFilename = 'app/Mage.php';
    require_once $mageFilename;
    Mage::setIsDeveloperMode(true);
    ini_set('display_errors', 1);
    umask(0);
    Mage::app('admin');
    Mage::register('isSecureArea', 1);
    Mage::app()->setCurrentStore(Mage_Core_Model_App::ADMIN_STORE_ID);

    set_time_limit(0);
    ini_set('memory_limit','1024M');

Answer 1

如果您只想匹配中间部分，请使用%

$sql = "SELECT sku FROM table WHERE item LIKE '%$code%'";

Answer 2

你必须在两个函数中放入DevZer0中所说的类似条件，因为它们都被调用。最后的代码行将首先调用_checkIfSkuExists($_data[0])，然后_updatePrices($_data)调用$productId = _getIdFromSku($sku);

喜欢声明匹配部分字符串
