我希望从以数据形式存储的数据库中获取数据。当我对回显值感到恐惧时,它会显示我不想要的值。
所以当我回显国家时,它会显示AX,我在寻找奥兰群岛的价值存储在数据库中。
<form action="reg_page.php" id="regform">
Username:<input type="text" name="username">
Password:<input type="text" name="password">
Confirm Password:<input type="text" name="conpassword">
Country:
<select id="city" name="city" required>
<option value="AX">Aland Islands</option>
<input type="submit">
</form>
include("db.php"); // include the connection object from the DBConnection.php
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
$inUsername = $_POST["username"];
$inPassword = $_POST["password"];
$encryptPassword = password_hash($inPassword, PASSWORD_DEFAULT);
$inCountry = $_POST["city"];
$stmt = $db->prepare("INSERT INTO users(username,password,center) VALUES(?, ?,?)");
$stmt->bind_param("sss", $inUsername , $encryptPassword, $inCountry);
$stmt->execute();
$result = $stmt->affected_rows;
$stmt -> close();
$db -> close();
if($result > 0)
答案 0 :(得分:0)
这是我的建议 在理想的世界中,您将拥有一个额外的数据库表,其中包含城市密钥和响应的城市名称。
// fiktive Table Cities with dummy values
id | Short | Name
--------------
24 | VIE | "Vienna"
53 | AX | "Aland Islands"
....
然后,您将在表users
中存储ID或密钥。然后,当您获得数据时,您将在两个表上进行连接。
更简单(但不是最好的)最终解决方案是“存储”那些硬编码为数组的对,您可以在输出时引用它:
// array with cities you need
$cities = Array("AX"=>"Aland Island", "VIE"=>"Vienna", ....);
// data coming from database
$cityCode = "AX";
// would be something like
$cityCode = $row['city'];
// then you can do:
echo $cities[$cityCode]; // will output "Aland Island"
