亲爱的朋友，我有两个功能，也许我将来可能会有更多功能，但重点是当用户在同一文本字段上根据邮政编码搜索酒店时，应该调用函数 hotel_by_postel_code($textvalue) 并且当我根据国家搜索，然后应该调用函数 hotel_by_country($textvalue)。以下是应该显示结果的代码，但它根本没有显示结果。
<?php require_once("includes/header.php");?>
<?php require_once("includes/connection.php")?>
<?php
if(isset($_POST['submit'])){
$message ="";
$textvalue = $_POST['search'];
if(empty($allhotels = hotel_by_postel_code($textvalue)) || empty($allhotels = hotel_by_country($textvalue))){
$message = "There is no record in the database";
}
}else{
$allhotels = select_all_hotels();
}
?>

以下代码是函数本身
function hotel_by_country($country){
global $connection;
$query = "SELECT * FROM Hotels WHERE country ='{$country}'";
$hotel_set = mysql_query($query,$connection);
confirm_query($hotel_set);
return $hotel_set;
}
function hotel_by_postel_code($postal){
global $connection;
$query = "SELECT * FROM Hotels WHERE hotel_postal_code ='{$postal}'";
$hotel_set = mysql_query($query,$connection);
confirm_query($hotel_set);
return $hotel_set;
}
function select_all_hotels(){
global $connection;
$query = "SELECT *
FROM Hotels";
$hotel_set = mysql_query($query,$connection);
confirm_query($hotel_set);
return $hotel_set;
}
