Question

我为我的网站创建了注册表，但我有一个问题。

我为city，country，state和business_category创建了一个数据库。

此代码仅适用于其他国家/地区的原因无效？

这是注册表单页码选择选项：

    <?php   
  include("includes/function.php");

?>

这段代码是我选择框的function.php代码

<?php 
include("connect.php");
function connect() {
mysql_connect($db_host,$db_user,$db_pass) or die('happy coding ' . mysql_error());
    mysql_select_db($db_name);
}


function close() {


mysql_close();

   }


function query() {
     $myData = mysql_query("SELECT * FROM country");

 while($record = mysql_fetch_array($myData)){
      echo '<option value="' . $record['country_name'] . '">' . $record['country_name'] . '</option>';
     } 

 }
 ?>

Answer 1

首先，您需要将要列出的表传递给查询函数

function query( $place) {
   $sql = "SELECT * FROM {$place}";
}

然后在适当的位置，您可以致电：

query('city');

和

query('country');

N.B请使用mysqli或PDO函数代替旧的mysql_函数。

$mysqli = new mysqli("localhost", "my_user", "my_password", "world");

function query($place) {
    global $mysqli;  // I don't like globals but this will fix your problem

    // create SQL statement as before
    $sql = "SELECT * FROM {$place}";
    $result = $mysqli->query($sql);
    while ($row = $result->fetch_array()) {
      // echo stuff here or build result string
    }
}

Answer 2

连接不是全局的。您必须将它传递给函数内部。

$conn = mysql_connect(...);

function query( $conn, $statement ) {
    $query = mysql_query( $statement );

    ... 
}

query( $conn, "SELECT ... ");

在您使用此功能时，请停止使用mysql_功能。它们不再被维护and are officially deprecated。请参阅red box？转而了解prepared statements，并使用PDO或MySQLi - this article将帮助您确定哪个。
