Magento删除额外的图像 - magento delete additional images

<?php
require 'app/Mage.php';
Mage::app();
$products = Mage::getModel('catalog/product')->getCollection()
                                        ->addAttributeToSelect('id')
                                        ->addAttributeToSelect('image')
                                        ->addAttributeToSelect('small_image')
                                        ->addAttributeToSelect('thumbnail_image');
foreach ($products as $product) {
  if (!$product->hasImage()) continue;
  if (!$product->hasSmallImage()) $product->setSmallImage($product->getImage());
  if (!$product->hasThumbnail()) $product->setThumbnail($product->getImage());
  $product->save();
}

我试图找出如何删除额外的图像与此代码，但我没有看到一个指南在网络上的任何地方:(我使用此代码设置小，缩略图的基础图像，现在我被卡住试图删除重复的额外图像。

这是我使用soap的c#版本的方法…你可能想知道我是怎么走到这一步的…阅读全文

private void RemoveImagesFromProduct()
        {
            try
            {    
                List<catalogProductImageEntity> imageList = this.mageObject.catalogProductAttributeMediaList(this.VendorProductId, null, "sku").ToList();
                // execute the soap call to remove each one
                foreach (catalogProductImageEntity catProdImg in imageList)
                {
                    this.mageObject.catalogProductAttributeMediaRemove(this.VendorProductId, catProdImg.file, "sku");
                }
            }
            catch (Exception exception)
            {
                this.SetProgressErrUpdate("Remove Image Handler Error");
                this.SetProgressErrUpdate(exception.Message);
            }
        }

在确定soap调用指向的位置后，我发现这些方法在Core Magento中使用:

(app/代码/核心/法师/目录/模型/产品/属性/媒体/Api.php)

     public function items($productId, $store = null, $identifierType = null)
     {
         $product = $this->_initProduct($productId, $store, $identifierType);
         $gallery = $this->_getGalleryAttribute($product);
         $galleryData = $product->getData(self::ATTRIBUTE_CODE);
         if (!isset($galleryData['images']) || !is_array($galleryData['images'])) {
             return array();
         }
         $result = array();
         foreach ($galleryData['images'] as &$image) {
             $result[] = $this->_imageToArray($image, $product);
         }
         return $result;
     }
     public function remove($productId, $file, $identifierType = null)
         {
             $product = $this->_initProduct($productId, null, $identifierType);
             $gallery = $this->_getGalleryAttribute($product);
             if (!$gallery->getBackend()->getImage($product, $file)) {
                 $this->_fault('not_exists');
             }
             $gallery->getBackend()->removeImage($product, $file);
             try {
                 $product->save();
             } catch (Mage_Core_Exception $e) {
                 $this->_fault('not_removed', $e->getMessage());
             }
             return true;
         }

至此，我知道了删除图像所必须做的一切，只是现在必须编写一个独立的函数。

// Set the product ID here, or load a collection and foreach it and use $product->getId()
        $prodId = 4967;
        // Reload here. Collections in magento are just unpredictable sometimes!
        $loadedProduct = Mage::getModel('catalog/product')->load($prodId);
        $attributes = $loadedProduct->getTypeInstance(true)->getSetAttributes($loadedProduct);
        if (isset($attributes['media_gallery'])) {
                // From this point forward, the gallery is represented by $attributes
                $gallery = $attributes['media_gallery'];
                $galleryData = $loadedProduct->getData('media_gallery');
                if (!isset($galleryData['images']) || !is_array($galleryData['images'])) {
                        die('no images for this product');
                }
                $result = array();
                foreach ($galleryData['images'] as &$image) {
                        $data = array(
                            'file'      => $image['file'],
                            'label'     => $image['label'],
                            'position'  => $image['position'],
                            'exclude'   => $image['disabled'],
                            'url'       => Mage::getSingleton('catalog/product_media_config')->getMediaUrl($image['file']),
                            'types'     => array()
                        );

                        foreach ($loadedProduct->getMediaAttributes() as $attribute) {
                            if ($loadedProduct->getData($attribute->getAttributeCode()) == $image['file']) {
                                $data['types'][] = $attribute->getAttributeCode();
                                }
                        }
                        $result[] = $data;
                }
                // At this point all the media info will be displayed for the product
                // From this point forward you just need to call the same parts of the remove soap api call
                foreach ($result as $galleryResult) {
                        // if the image exists, delete it.
                        if($gallery->getBackend()->getImage($loadedProduct, $galleryResult['file'])) {
                                $gallery->getBackend()->removeImage($loadedProduct, $galleryResult['file']);
                        }
                }
        }
