我正在使用 osCommerce 创建一个报告页面来显示每天销售的农产品总量。这是迄今为止我用来显示类别和子类别的标记:
<table border="0" width="100%" cellspacing="0" cellpadding="2">
<tr class="dataTableHeadingRow">
<td class="dataTableHeadingContent"><?php echo TABLE_HEADING_PRODUCTS; ?></td>
<td class="dataTableHeadingContent" align="right"><?php echo TABLE_HEADING_TOTAL_WEIGHT; ?> </td>
</tr>
<?php
function category_list( $category_parent_id = 0 )
{
$sql = 'select cd.categories_name,c.categories_id, c.parent_id, c.sort_order from ' . TABLE_CATEGORIES . ' c, ' . TABLE_CATEGORIES_DESCRIPTION . ' cd where c.categories_id = cd.categories_id AND c.parent_id='.$category_parent_id;
$res = tep_db_query( $sql );
$cats = array();
while ( $cat = tep_db_fetch_array( $res ) )
{
$cats[] = $cat;
}
if (count($cats) == 0)
{
return '';
}
$list_items = array();
foreach ( $cats as $cat )
{
$list_items[] = '<tr class="dataTableRow"><td class="dataTableContent">';
if($category_parent_id != 0)$list_items[] = ' ';
if($category_parent_id == 0)$list_items[] = '<b>';
$list_items[] = $cat['categories_name'];
if($category_parent_id == 0)$list_items[] = '</b>';
$list_items[] = '</td><td class="dataTableContent">';
$list_items[] = category_list( $cat['categories_id'] );
$list_items[] = '</td></tr>';
}
$list_items[] = '';
return implode( '', $list_items );
}
echo category_list();
?>
</table>
我想在子类别之后显示的是每个产品中的产品,这意味着使用TABLE_PRODUCTS_TO_CATEGORIES
表格。我有以下代码用于计算产品$query = 'SELECT COUNT(*) FROM '.TABLE_PRODUCTS_TO_CATEGORIES.' WHERE
categories_id` = "'.$cat['categories_id'].'"';。
我将把它放在我的标记中的哪里,我将如何展示产品?
