Question

我正在使用Magento（1.6.2.0）XMLRPC-API来分配/删除某个类别的产品。我最近查看了异常日志，发现有很多异常。每当我更新类别时，都会发生以下错误：

2012-03-14T10:35:33+00:00 ERR (3):

该类别已成功更新，但我仍然想知道为什么会这样。

Answer 1

Magento 2中包含的“官方”修复：

class Mage_Catalog_Model_Category_Attribute_Backend_Image extends Mage_Eav_Model_Entity_Attribute_Backend_Abstract
{

    /**
    * Save uploaded file and set its name to category
    *
    * @param Varien_Object $object
    * @return Mage_Catalog_Model_Category_Attribute_Backend_Image
    */
    public function afterSave($object)
    {
        $value = $object->getData($this->getAttribute()->getName());

        // if no image was set - nothing to do
        if (empty($value) && empty($_FILES)) {
            return $this;
        }

        if (is_array($value) && !empty($value['delete'])) {
            $object->setData($this->getAttribute()->getName(), '');
            $this->getAttribute()->getEntity()
                ->saveAttribute($object, $this->getAttribute()->getName());
            return $this;
        }

        $path = Mage::getBaseDir('media') . DS . 'catalog' . DS . 'category' . DS;

        try {
            $uploader = new Mage_Core_Model_File_Uploader($this->getAttribute()->getName());
            $uploader->setAllowedExtensions(array('jpg','jpeg','gif','png'));
            $uploader->setAllowRenameFiles(true);
            $result = $uploader->save($path);

            $object->setData($this->getAttribute()->getName(), $result['file']);
            $this->getAttribute()->getEntity()->saveAttribute($object, $this->getAttribute()->getName());
        } catch (Exception $e) {
            if ($e->getCode() != Mage_Core_Model_File_Uploader::TMP_NAME_EMPTY) {
                Mage::logException($e);
            }
            /** @TODO ??? */
        }
        return $this;
    }
}

Answer 2

解决方法：

将此重写添加到config.xml

中的自定义模块（即catalogextended）

    <models>
        <catalogextended>
            <class>Myname_Catalogextended_Model</class>
        </catalogextended>
        <catalog>
            <rewrite>
                <category_attribute_backend_image>Myname_Catalogextended_Model_Category_Attribute_Backend_Image</category_attribute_backend_image>
            </rewrite>
        </catalog>
    </models>

并添加此文件：

app/code/local/Myname/Catalogextended/Model/Category/Attribute/Backend/Image.php

含：

/**
 * Save uploaded file and set its name to category
 *
 * @param Varien_Object $object
 */
public function afterSave($object)
{
    $value = $object->getData($this->getAttribute()->getName());

    if (is_array($value) && !empty($value['delete'])) {
        $object->setData($this->getAttribute()->getName(), '');
        $this->getAttribute()->getEntity()
            ->saveAttribute($object, $this->getAttribute()->getName());
        return;
    }

    /* Workaround to avoid exception '$_FILES array is empty' when assiging
     * products to a category or creating a category with the API.
     * Inspired by http://www.magentocommerce.com/bug-tracking/issue/?issue=11597
     */
    if (!isset($_FILES) || count($_FILES) == 0)
    {
        return;
    }

    $path = Mage::getBaseDir('media') . DS . 'catalog' . DS . 'category' . DS;

    try {
        $uploader = new Mage_Core_Model_File_Uploader($this->getAttribute()->getName());
        $uploader->setAllowedExtensions(array('jpg','jpeg','gif','png'));
        $uploader->setAllowRenameFiles(true);
        $result = $uploader->save($path);

        $object->setData($this->getAttribute()->getName(), $result['file']);
        $this->getAttribute()->getEntity()->saveAttribute($object, $this->getAttribute()->getName());
    } catch (Exception $e) {
        if ($e->getCode() != Mage_Core_Model_File_Uploader::TMP_NAME_EMPTY) {
            Mage::logException($e);
        }
        /** @TODO ??? */
        return;
    }
  }
}

Answer 3

Mondane答案启发的其他选项是：

copy /app/code/core/Mage/Catalog/Model/Category/Attribute/Backend/Image.php to /app/code/local/Mage/Catalog/Model/Category/Attribute/Backend/Image.php < / LI>
（如果您没有路径CREATE IT）

之后编辑您创建的文件

用此代码替换afterSave函数

public function afterSave($object)
{
    $value = $object->getData($this->getAttribute()->getName());

    if (is_array($value) && !empty($value['delete'])) {
        $object->setData($this->getAttribute()->getName(), '');
        $this->getAttribute()->getEntity()
            ->saveAttribute($object, $this->getAttribute()->getName());
        return;
    }

    /* Workaround to avoid exception '$_FILES array is empty' when assiging
     * products to a category or creating a category with the API.
     * Inspired by http://www.magentocommerce.com/bug-tracking/issue/?issue=11597
     */
    if (!isset($_FILES) || count($_FILES) == 0)
    {
        return;
    }

    $path = Mage::getBaseDir('media') . DS . 'catalog' . DS . 'category' . DS;

    try {
        $uploader = new Mage_Core_Model_File_Uploader($this->getAttribute()->getName());
        $uploader->setAllowedExtensions(array('jpg','jpeg','gif','png'));
        $uploader->setAllowRenameFiles(true);
        $result = $uploader->save($path);

        $object->setData($this->getAttribute()->getName(), $result['file']);
        $this->getAttribute()->getEntity()->saveAttribute($object, $this->getAttribute()->getName());
    } catch (Exception $e) {
        if ($e->getCode() != Mage_Core_Model_File_Uploader::TMP_NAME_EMPTY) {
            Mage::logException($e);
        }
        /** @TODO ??? */
        return;
    }
  }
}

通过这样做，您将替换magento代码而不涉及核心文件，因为magento将在获取原始文件之前自动获取此文件
