查询中的连接有点奇怪，在ON
子句中有常量
...
JOIN customers as c ON c.invoice = ".$getID."
JOIN invoice_items as p ON p.invoice = ".$getID."
...
您需要这样做。ON子句需要表示三个表中的行之间的关系。将常量值放在这些子句中会失败。请使用WHERE
子句筛选正确的发票号
SELECT something, something
FROM invoices as i
JOIN customers as c ON c.invoice = i.invoice
JOIN invoice_items as p ON p.invoice = i.invoice
WHERE i.invoice = ".$getID."
ORDER BY i.invoice
其次，您确定在这三个表中都有一个名为invoice
的列吗？您的代码稍后提到了一个名为invoice\u id
的列。这实际上是您的join列的名称吗
第三，php代码似乎希望三个表中的两个表中的列出现在结果集中
....
$customer_postcode_ship = $row['customer_postcode_ship'];
....
$invoice_number = $row['invoice_id'];
...
但是您选择了c.*客户SELECT*SELECT customer_name, customer_email, customer_address_1, customer_address_2,
customer_town, customer_county, customer_postcode,
customer_phone, customer_name_ship, customer_address_1_ship,
customer_address_2_ship, customer_town_ship, customer_county_ship,
customer_postcode_ship,
invoice_id, invoice_date, invoice_due_date, invoice_subtotal,
invoice_shipping, invoice_discount, invoice_vat, invoice_total,
invoice_notes, invoice_status
FROM ...
发票项目表中的每个匹配行都会重复一次您的客户和发票列值
第五：检查$mysqli->query（$query）；
返回的错误
当您使用SQL时，这些东西最终将成为第二天性。不要对正确操作的复杂性感到过分恼火！Done var_dump（$results）和get back NULL-因此可能SELECT查询是错误的-表是发票、客户和发票项-都包含发票（作为ID）回复很好Ollie，我做了很多更改，但我没有运气！我完成了对结果和查询的var_转储，我得到以下信息：“选择客户名称、客户电子邮件、客户地址1、客户地址2、客户镇、客户县、客户邮编、客户电话、客户
$results = $mysqli->query($query);
if (!$results) {
printf("Errormessage: %s\n", $mysqli->error);
} else {
/* process the resultset */
}
