【问题描述】：
我有一个旅游搜索应用程序，用户可以在其中根据三个不同的参数（地区、国家和时长）搜索可用的旅游。目前我正在使用的代码在同一页面中显示输出结果。我希望输出结果显示在不同的页面中。
下面是我的 PHP 代码：
<?php
mysql_connect("localhost", "root", "");
mysql_select_db("byp");
if(isset($_POST['submit'])){
$region=$_POST['region'];
$country=$_POST['country'];
$duration=$_POST['duration'];
//define the index for the All option
$optionAllValue = 0; //add here the option index value used for the 'All' option
//define the where clause for the query
//in order to avoid many conditions verifications, we start it as 1=1
$whereClause = "1=1";
//now we check if the option selected for each field is not the value defined for the option 'All'
//this is just an example, and the best would be to create a function to avoid the replication of code
if($region != $optionAllValue)
{
$whereClause = $whereClause." and region='$region'";
}
if($country != $optionAllValue)
{
$whereClause = $whereClause." and country='$country'";
}
if($duration != $optionAllValue)
{
$whereClause = $whereClause." and duration='$duration'";
}
$query = "select * from byp_tour where ".$whereClause;
//original query select * from byp_tour where region='$region' and country='$country' and duration='$duration'"
$tour = mysql_query($query);
$tourNum = mysql_num_rows($tour);
if($tourNum >0){
while($result=mysql_fetch_array($tour)){
$tour_name = $result['tour_name'];
$tour_detail = $result['tour_detail'];
echo "Tour Name: $tour_name"; // HERE IS THE OUTPUT RESULT
echo "<br />";
echo "Tour Detail: $tour_detail";
echo "<br />";
echo "<br />";
echo "<br />";
}
}
else{
echo "No Tour Found";
echo "<br />";
echo "<br />";
}
}
?>

注意：您正在使用的
mysql_*函数正在被弃用，并将从未来的 PHP 版本中删除。您不应该使用它们编写新代码，而是使用mysqli_*或 PDO。 -
我想获得有关可以在另一个页面中回显结果的确切代码的帮助。
