Question

我有一个旅游搜索应用程序，用户可以根据三个不同的参数搜索可用的游览 - 区域，国家和持续时间。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。

Database Structure

以下是我的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 />";
        }
    }
?>
