亲爱的朋友我有两个功能，也许我可能有更多的未来，但重点是，我想当一个用户搜索酒店基于同一文本字段上的邮政编码功能 应该调用hotel_by_postel_code（$ textvalue），并且当我根据国家进行搜索时，应调用hotel_by_country（$ textvalue）函数 。以下是应该显示结果的代码，但它不是应该显示结果的代码。调用不同的功能为不同的搜索选项
<?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();
}
?>

和下面的代码是函数本身
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;
}

@swapnesh是的。 – alfasin 2012-07-26 05:38:35
这不是原因，因为我尝试了两个，它仍然无法正常工作。 – 2012-07-26 05:42:56
