Virtuemart 添加到购物车，价格详细信息等未出现

Question

我有 Joomla Virtuemart 网站，我不小心卸载了 Virtuemart，但幸运的是我有备份，所以我再次将大部分文件覆盖到服务器，并将一些 MySQL 数据写入数据库，但我似乎无法获取价格并添加到购物车等详细信息显示在产品详细信息页面中。

发生这种情况有原因吗？我是否错过了某个表或数据库？

我不确定我应该在产品详细信息页面中查看哪个文件...

感谢您的帮助。

以下是产品详细信息页面的代码：

<?php if( !defined( '_VALID_MOS' ) && !defined( '_JEXEC' ) ) die( 'Direct Access to '.basename(__FILE__).' is not allowed.' );
mm_showMyFileName(__FILE__);
require_once ( CLASSPATH. 'ps_product.php');
$ps_product = new ps_product;

 ?>
<div id="ttn_prdDetail_wrapper"><div id="product_list_inner1"><div id="product_list_inner2"><div id="product_list_inner3">
<?php if( $this->get_cfg( 'product_navigation', 1 )) {
    if( !empty( $previous_product )) {
        echo '<a class="previous_page" href="'.$previous_product_url.'">'.shopMakeHtmlSafe($previous_product['product_name']).'</a>';
    }
    if( !empty( $next_product )) {      
        echo '<a class="next_page" href="'.$next_product_url.'">'.shopMakeHtmlSafe($next_product['product_name']).'</a>';
    }
} ?>
<br clear="all"/>
    <?php $ttn_prdName = explode('|',$product_name,2);?>
    <h1 class="prdName">

        <?php echo $ttn_prdName[0] ?> <?php echo $edit_link ?>
    </h1>
    <div class="prdImages">
        <div class="mainImage">
        <?php  echo $product_image ?>
        </div>
        <h2> More images (click to enlarge)</h2>
        <div id="altviews">
            <div class="alter_img">
            <?php  echo $product_image2 ?>
            </div>
            <?php  echo $this->vmlistAdditionalImages( $product_id, $images ) ?>
            <div style="clear:both;"></div>
        </div>
    </div>
    <div class="prdDesc_wrapper">
        <?php echo $product_description ?>
    </div>
    <div style="clear:both;"></div>

</div></div></div></div>
<!--Show bottom note ò prdoduct--->
<div class="prdBotNote">
        <?php echo $this->get_cfg('ttn_botnote')?>
    </div>
<?php
// Show Featured Products
if( $this->get_cfg( 'showFeatured', 1 )) {
    /* featuredproducts(random, no_of_products,category_based) no_of_products 0 = all else numeric amount
    edit featuredproduct.tpl.php to edit layout */
?>
    <div id="ttn-fp"><div id="ttn-fp-inner1"><div id="ttn-fp-inner2"><div id="ttn-fp-inner3">
<?php
    echo $ps_product->ttnfeaturedProducts(true,50,true);
?>
    </div></div></div></div>
<?php
}
?>

我还有一个 jos_vm_weblinks 表，但我怀疑这会是问题的原因。您说您已“再次将大部分文件覆盖到服务器”；你是怎么做到的？如果您还没有这样做，也许全新安装 Joomla/Virtuemart 会有所帮助？然后，您可以简单地删除它安装的数据库架构，并再次用您自己的数据库架构替换它。

我还建议检查您的错误日志 (/logs/error.txt) 以查看是否报告了任何内容。检查 Apache 错误日志也没什​​么坏处。另外，您是否检查过是否正确插入了旧数据库信息？我知道这是一个非常明显的建议，但我总是做这样的傻事！
