Question

如何在opencart中对我的产品进行排序，如下所示，

所有产品将按订单排序，但缺货产品（即数量= 0）将列在该类别的末尾！

Answer 1

在opencart 2.2中，您必须更改catalog \ model \ catalog \ product.php

找到

if (isset($data['sort']) && in_array($data['sort'], $sort_data)) {
   if ($data['sort'] == 'pd.name' || $data['sort'] == 'p.model') {
            $sql .= " ORDER BY LCASE(" . $data['sort'] . ")  ";
        } elseif ($data['sort'] == 'p.price') {
            $sql .= " ORDER BY (CASE WHEN special IS NOT NULL THEN special WHEN discount IS NOT NULL THEN discount ELSE p.price END)";
        } else {
            $sql .= " ORDER BY " . $data['sort'];
        }
} else {
        $sql .= " ORDER BY p.sort_order";
}

并在＆＃34; ORDER BY＆＃34;

之后添加其他订单规则 p.quantity＆lt; 1

if (isset($data['sort']) && in_array($data['sort'], $sort_data)) {
   if ($data['sort'] == 'pd.name' || $data['sort'] == 'p.model') {
            $sql .= " ORDER BY       p.quantity<1,               LCASE(" . $data['sort'] . ")  ";
        } elseif ($data['sort'] == 'p.price') {
            $sql .= " ORDER BY       p.quantity<1,               (CASE WHEN special IS NOT NULL THEN special WHEN discount IS NOT NULL THEN discount ELSE p.price END)";
        } else {
            $sql .= " ORDER BY       p.quantity<1,                " . $data['sort'];
        }
} else {
        $sql .= " ORDER BY           p.quantity<1,                p.sort_order";
}

Answer 2

您可以有2个查询。一个，其中quantity != 0 ORDER BY sort_order和秒 quantity = 0。然后，您可以合并记录并获得所需的输出。

Opencart在类别结束时显示缺货
