我想在产品页面中显示我的所有折扣优惠，我在后端总共有 5 个优惠这是代码 <?php foreach ($discounts as $discount) { ?> <?php echo $discount['quantity']; ?><?php echo $text_discount; ?><?php echo $discount['price']; ?><br /> <?php } ?但结果是第一个报价被忽略了，它从第二个值开始数组的输出是 Array ( [0] => Array ( [quantity] => 40 [price] => $5.00 ) [1] => Array ( [quantity] => 160 [price] => $4.00 ) [2] => Array ( [quantity] => 320 [price] => $3.90 ) [3] => Array ( [quantity] => 480 [price] => $3.50 ) )和优惠的后端设置是有什么办法可以显示所有优惠吗？

尝试运行以下命令：
<html>
<head></head>
<body>
<-- Other html code -->
<?php
foreach($discounts as $discount) {
echo $discount['quantity'] . ' or more '. $discount['price'] .'<br>';
}
?>
<-- Other html code -->
</body>
</html>

在此处更改
public function getProductDiscounts($product_id) {
$query = $this->db->query("SELECT * FROM " . DB_PREFIX . "product_discount WHERE product_id = '" . (int)$product_id . "' AND customer_group_id = '" . (int)$this->config->get('config_customer_group_id') . "' AND quantity >= 0 AND ((date_start = '0000-00-00' OR date_start < NOW()) AND (date_end = '0000-00-00' OR date_end > NOW())) ORDER BY quantity ASC, priority ASC, price ASC");
return $query->rows;
}
请AND quantity > 1 改为AND quantity >= 0
