如何在洋红色的购物车页面上显示自定义图像

Question

我想在Magento的购物车页面上显示产品的自定义图像。

配置.xml文件

<checkout>
    <rewrite>
        <cart_item_renderer>ProductCustomizer_ProductCustomizer_Block_Checkout_Cart_Item_Renderer</cart_item_renderer>
    </rewrite>
</checkout>

我在块/结帐/购物车/项目/渲染器.php文件中添加了以下代码

<?php
class ProductCustomizer_ProductCustomizer_Block_Checkout_Cart_Item_Renderer extends Mage_Checkout_Block_Cart_Item_Renderer{
    public function getProductThumbnail()
    {
        $item = $this->_item;
        $customize_data = $item->getData('customize_data');
        $customize_image = $item->getData('customize_image');
        $results_data = $item->getOptionByCode("customizer_data")->getValue();
        if(!is_null($results_data)){
            $results = unserialize($results_data); 
            $path = Mage::getBaseDir()."/skin/";
            $_product = $item->getProduct()->load();
            $customize_image = $this->helper('catalog/image')->init($_product, 'thumbnail',$path.'adminhtml/default/default/images/logo.gif');
            //$customize_image = $this->helper('catalog/image')->init($_product, 'thumbnail',$results['image']);
        }
        if (!empty($customize_image)) {
            return $customize_image;
        } else {
            return parent::getProductThumbnail();
        }
    }
}

我已经尝试使用图像"URL"，"路径"和"数据（data:image/png;base64,iVBORw0KG....）"进行$customize_image，但它不起作用。

Answer 1

所以这就是这个想法。您正在调用的 init 函数正在为您创建问题。做这样的事情，因为你已经完成了该类的覆盖。

public function getProductThumbnail1()
    {
        if (!is_null($this->_productThumbnail)) {
            return $this->_productThumbnail;
        }
        return $this->getSkinUrl('images/jhonson.jpg');
        //return $this->helper('catalog/image')->init($this->getProduct(), 'thumbnail');
    }

将此函数添加到您已经覆盖的类中，该类Mage_Checkout_Block_Cart_Item_Renderer。现在，在您的app/design/frontend/rwd/default/template/checkout/cart/item/default.phtml文件或任何文件中，像这样调用此函数echo $this->getProductThumbnail1()而不是此echo $this->getProductThumbnail()->resize(180)。

我已经找到了解决方案。你已经覆盖了核心类，我在下面添加了类。

在自定义模块的帮助程序中创建帮助程序"自定义图像.php"

<?php
class ProductCustomizer_ProductCustomizer_Helper_Customezerimage extends Mage_Catalog_Helper_Image {
    public function setCustomeImage($path){
        $this->_imageFile = $path;
        $this->_setModel(Mage::getModel('productcustomizer/product_image'));
        $this->_getModel()->setCustomeBaseFile($this->_imageFile);
        return $this;
    }
    public function __toString() {
        try {
            $model = $this->_getModel();
            $url = $model->getUrl();
        } catch (Exception $e) {
            $url = Mage::getDesign()->getSkinUrl($this->getPlaceholder());
        }
        return $url;
    }
}

在自定义模块的模型/产品目录中创建模型"图像.php"。

    <?php 
class ProductCustomizer_ProductCustomizer_Model_Product_Image extends Mage_Catalog_Model_Product_Image{
    public function setCustomeBaseFile($baseFile){
        if (!file_exists($baseFile)) {
            throw new Exception(Mage::helper('catalog')->__('Image file was not found.'));
        }
        $this->_newFile = $this->_baseFile = $baseFile;
        return $this;
    }
    public function saveCustomeImage($file = ""){
        if(empty($file)){
            $file = $this->_newFile;
        }
        Mage::log($file);
        $this->getImageProcessor()->save($file);
        return ;
    }
    public function getUrl(){
        $baseDir = Mage::getBaseDir();
        $path = str_replace($baseDir . DS, "", $this->_newFile);
        return Mage::getBaseUrl() . str_replace(DS, '/', $path);
    }
}

现在，您可以设置要在购物车中显示的自定义图像路径，如下所示

<?php
class ProductCustomizer_ProductCustomizer_Block_Checkout_Cart_Item_Renderer extends Mage_Checkout_Block_Cart_Item_Renderer{
    public function getProductThumbnail()
    {
        $item = $this->_item;
        $customize_data = $item->getData('customize_data');
        $customize_image = $item->getData('customize_image');
        $results_data = $item->getOptionByCode("customizer_data")->getValue();
        if(!is_null($results_data)){
            $results = unserialize($results_data); 
            $imagePathFull = $customize_image;
            $_product = $item->getProduct();
            $image = $imagePathFull;
            return $this
                ->helper('productcustomizer/customezerimage')
                ->init($_product, 'thumbnail')->setCustomeImage($image);
        }else{
            return parent::getProductThumbnail();
        }
    }
}
