我正在使用 OC 2.2.0，并且我制作了自定义最新页面，其中显示 20 个最新产品。我设法将默认排序设置为按降序添加的日期。由于某种原因，我正在努力使其他排序选项(按名称、价格和型号)正常工作。显示了正确的产品数量(在我的例子中为 20)，但它们不是最新的。它们只是所有产品列表中的产品。我的

在
model-catalog-product-product.php file I made function getProductLatestS($data = array())
public function getProductLatestS($data = array()) {
$sql = "SELECT DISTINCT p.product_id FROM oc_product p LEFT JOIN oc_product_description pd ON (p.product_id = pd.product_id) LEFT JOIN oc_product_to_store p2s ON (p.product_id = p2s.product_id) WHERE p.status = '1' AND p.stock_status_id = '7' AND p.date_available <= NOW() AND p2s.store_id = '0' GROUP BY p.product_id";
$sort_data = array(
'pd.name',
'p.model',
'p.date_available',
'p.date_added',
'p.price',
'rating',
'p.sort_order'
);
if (isset($data['sort']) && in_array($data['sort'], $sort_data)) {
if ($data['sort'] == 'pd.name' || $data['sort'] == 'p.model') {
$sql .= " ORDER BY LCASE(" . $data['sort'] . ")";
} else {
$sql .= " ORDER BY " . $data['sort'];
}
} else {
$sql .= " ORDER BY p.date_added";
}
if (isset($data['order']) && ($data['order'] == 'DESC')) {
$sql .= " DESC, LCASE(pd.name) DESC";
} else {
$sql .= " ASC, LCASE(pd.name) ASC";
}
if (isset($data['start']) || isset($data['limit'])) {
if ($data['start'] < 0) {
$data['start'] = 0;
}
if ($data['limit'] < 1) {
$data['limit'] = 20;
}
$sql .= " LIMIT " . (int)$data['start'] . "," . (int)$data['limit'];
}
$product_data = array();
$query = $this->db->query($sql);
foreach ($query->rows as $result) {
$product_data[$result['product_id']] = $this->getProduct($result['product_id']);
}
return $product_data;
}
我的问题是如何使其他排序也能正常工作(按两个参数排序，添加日期始终是第一个参数)？欢迎任何建议，因为我不知道我在这里做错了什么。谢谢。
最佳答案
我意识到我的代码出了什么问题。
问题出在我在 getProductLatestS($data = array()) 函数中的查询中。我没有定义时间间隔。比如说，如果您只想获取最近 10 天内添加的产品，则需要定义时间间隔，就像我最终在查询中所做的那样:
$sql = "SELECT DISTINCT p.product_id FROM oc_product p LEFT JOIN oc_product_description pd ON (p.product_id = pd.product_id) LEFT JOIN oc_product_to_store p2s ON (p.product_id = p2s.product_id) WHERE p.status = '1' AND p.stock_status_id = '7' AND p.date_added BETWEEN DATE_SUB(NOW(), INTERVAL 10 DAY) AND NOW() AND p2s.store_id = '0' ";
我希望这对某人有帮助。干杯。
