Question

首先，我需要创建一个表单，允许用户输入起始邮政编码和结尾邮政编码，并在该范围内的所有邮政编码之间输出记录列表。它们也必须按姓氏排序。到目前为止，这就是我所拥有的。它可以工作，如果我从我的插入文件发送值到我的客户文件，但客户文件本身有一个错误，我无法弄清楚。我也无法弄清楚如何按姓氏对它们进行排序。

<!DOCTYPE html>
<html>
<body>

Find all customers between these two ranges.

<form action="Customers.php" method="get">

Beginning Zip:
<input type="text" name="Zip1">

Ending Zip:
<input type="text" name="Zip2">

<button type="sumbit">Find</button>

</form>
</body>
</html>

邮政编码在此处发送。他们应该使用该范围之间的邮政编码检索和发布客户，并按姓氏对其进行排序。此文件本身也不起作用并显示错误。

SELECT userID, FirstName, LastName, Address1, City, State, Zip FROM Customers WHERE Zip > AND Zip < ;No records returned:

        echo htmlentities($row["FirstName"]);

        echo "<button type='Submit'>Delete</button>";

        echo "</p>";
    }

} else {
    echo "No results returned";
}
}
$conn->close(); //this is not necessary because connection closes automatically
?>

有人能发现错误吗？

我需要有关PHP和My SQL错误的建议
