Question

我需要更换模板PDF中的条形码，

代码：

using (new SecurityDisabler())
{
    DateTime archiveDate = new DateTime(2015, 9, 8);
    string pathPrefix = "/sitecore/media library";

    // get the recyclebin for the master database
    Sitecore.Data.Archiving.Archive archive = Sitecore.Data.Database.GetDatabase("master").Archives["recyclebin"];

    // get as many deleted items as possible 
    // where the archived date is after a given date 
    // and the item path starts with a given path
    var itemsRemovedAfterSomeDate =
        archive.GetEntries(0, int.MaxValue)
                .Where(entry => 
                    entry.ArchiveDate > archiveDate && 
                    entry.OriginalLocation.StartsWith(pathPrefix)
                ).ToList();

    foreach (var itemRemoved in itemsRemovedAfterSomeDate)
    {
        // restore the item
        archive.RestoreItem(itemRemoved.ArchivalId);
    }
}

模板HTML：

$tmp_product = str_replace("{::prod_price}", $product['price'], $tmp_product);
$eancodes = $product['ean']; 
$eancode =  new TCPDFBarcode($eancodes, 'EAN13'); 
$tmp_product = str_replace("{::prod_ean}", $eancode, $tmp_product);

根据TCPDFBarcode documentation文档，TCPDFBarcode类为您提供了一种可用于显示条形码的方法：

getBarcodeHTML - 返回条形码的HTML表示。您可以将此HTML直接插入到PDF_TEMPLATE_PROD模板

使用getBarcodeHTML方法可以执行以下操作：

// define the HTML template you'll use to markup the product data
define('PDF_TEMPLATE_PROD', '  
    <tr class="pdf_prod" id="{::prod_name}" nobr="true">         
        <td class="pdf_prod_desc">               
            <ul class="pdf_prod_ul">
                <li><strong>{::txt_prod_price}</strong> {::prod_price}</li>            
                <li class="pdf_prod_bcode">{::prod_ean}</li>
            </ul>
        </td> 
    </tr>

    ');

// pass the template into a variable where you'll fill in the data
$tmp_product = constant('PDF_TEMPLATE_PROD');
// insert the price
$tmp_product = str_replace("{::prod_price}", $product['price'], $tmp_product);

// extract the data you want to encode and create your TCPDFBarcode object:
$eancodes = $product['ean'];
$eancode =  new TCPDFBarcode($eancodes, 'EAN13'); 

// insert the HTML represenation of the barcode and print the result
$tmp_product = str_replace("{::prod_ean}", $eancode->getBarcodeHTML(), $tmp_product);
echo $tmp_product;
