在excel中保存Magento條碼圖像

Question

我試圖保存生成並在Excel中保存條碼。但是，我有問題以正確的格式保存圖像。圖像保存在最後一列。但是，我不知道如何保存它。

希望有人能幫忙。代碼如下：

<?php 

require_once '../app/Mage.php'; 
umask(0); 
Mage::app(); 
Mage::app()->loadArea(Mage_Core_Model_App_Area::AREA_FRONTEND); 

header("Content-type:text/octect-stream"); 
header("Content-Disposition:attachment;filename=exportMyEANCodes.csv"); 

$eanPrefixCode=""; 

$storeId = Mage::app()->getStore()->getId(); 
$product = Mage::getModel('catalog/product'); 
$products = $product->getCollection()->addStoreFilter($storeId)->getAllIds(); 

echo '"sku","ean","barcode"'. "\n"; 

foreach($products as $productid) 
{ 
$product = Mage::getModel('catalog/product')->load($productid); 

$sku = $product->getSku(); 

$ean=ean13_check_digit($eanPrefixCode. str_pad($product->getId(), 5, "0", STR_PAD_LEFT)); 

$bc = new barCode(); 
//$bc->build($ean); 

$output='"'. $sku. '","'. $ean. '","'.$bc->build($ean).'"'; 
echo $output. "\n"; 
} 

$bc = new barCode(); 
$bc->build($ean); 


function ean13_check_digit($digits){ 
$digits =(string)$digits; 
$even_sum = $digits{1} + $digits{3} + $digits{5} + $digits{7} + $digits{9} + $digits{11}; 
$even_sum_three = $even_sum * 3; 
$odd_sum = $digits{0} + $digits{2} + $digits{4} + $digits{6} + $digits{8} + $digits{10}; 
$total_sum = $even_sum_three + $odd_sum; 
$next_ten = (ceil($total_sum/10))*10; 
$check_digit = $next_ten - $total_sum; 
return $digits . $check_digit; 
} 


class barCode 
{ 
    public $bcHeight, $bcThinWidth, $bcThickWidth, $bcFontSize, $mode;

我做了一些測試，我也看到了很多相同的字符！

也許一種替代方法：讓腳本輸出所需的CSV文件，但在第三個字段中輸入一個URL。你能在var/export/sku.php一個小腳本：

<?php 
require_once '../../app/Mage.php'; 
umask(0); 
Mage::app(); 
Mage::app()->loadArea(Mage_Core_Model_App_Area::AREA_FRONTEND); 
if(isset($_GET['sku']) && strlen($_GET['sku']) > 5) { 
    header('Content-Type: image/jpeg'); 
    $barcodeOptions = array('text' => $_GET['sku']); 
    $rendererOptions = array(); 
    $imageResource = Zend_Barcode::draw( 
     'code39', 'image', $barcodeOptions, $rendererOptions 
    ); 
    imagejpeg($imageResource); 
} ?> 

然後在你的腳本，你必須(sku),ean,http://yoursite.com/var/export/sku.php?sku=(sku)有辦法讓電子表格加載圖像 - 雖然我還沒有這樣做就個人而言，我所看到的鏈接顯示爲嵌入圖像。

我上面的示例輸出一個code39條形碼，它是可掃描的。你可以用你自己的圖像代替代。這就是爲什麼我問你是否看到條形碼，因爲我以前沒有輸出過這樣的圖像。
