[3]一个简单实现多条件查询的例子
    来源: 互联网  发布时间: 2013-11-30
在我们的网站设计过程中，经常会用到多条件查询，本文的源码是一个二手房屋查询的例子。在本例中，我们要实现能够通过地理位置，物业类型，房屋价格，房屋面积及信息发布日期等多个条件查询到客户所需的资料。以下是实现过程。
查询条件界面(略)：
查询文件（search.php）
一、生成查询语句：
<?
$conn=mysql_connect("localhost","root","");
$db=mysql_select_db("lingyun");
$query="select * from message where tradetype='".$tradetype."'";  //交易类型，如出租，出售
$SQL=$SQL . "wuye='" . $wuye . "'";
if($housetype!="不限"){
$query.=" && housetype='".$housetype."'"; //房屋类型，如二室一厅，三室二厅
}
if($degree!="不限"){
$query.=" && degree='".$degree."'";  //新旧程度
}
if($wuye!="不限"){
$query.=" && wuye='".$wuye."'";   //物业类型 如住房，商铺
}
if($price2!=""){
switch($price1){
case "大于":
$query.=" && price>'".$price2."'";   //价格
break;
case "等于":
$query.=" && price='".$price2."'";
break;
case "小于":
$query.=" && price<'".$price2."'";
break;
}
}
if($area2!=""){
switch($area1){
case "大于":
$query.=" && area>'".$area2."'";  //面积
break;
case "等于":
$query.=" && area='".$area2."'";
break;
case "小于":
$query.=" && area<'".$area2."'";
break;
}
}
switch($pubdate){                   //发布日期
case "本星期内":
$query.=" && TO_DAYS(NOW()) - TO_DAYS(date)<=7";
break;
case "一个月内":
$query.=" && TO_DAYS(NOW()) - TO_DAYS(date)<=30";
break;
case "三个月内":
$query.=" && TO_DAYS(NOW()) - TO_DAYS(date)<=91";
break;
case "六个月内":
$query.=" && TO_DAYS(NOW()) - TO_DAYS(date)<=183";
break;
}
if($address!=""){
$query.=" &&  address like '%$address%'";  //地址
}
if(!$page){
$page=1;
}
?>

二、输出查询结果：
<?php
     if ($page){
     $page_size=20;
     $result=mysql_query($query);
     #$message_count=mysql_result($result,0,"total");
     $message_count=10;
     $page_count=ceil($message_count/$page_size);
     $offset=($page-1)*$page_size;
     $query=$query." order by date desc limit $offset, $page_size";
     $result=mysql_query($query);
     if($result){
     $rows=mysql_num_rows($result);
     if($rows!=0){
     while($myrow=mysql_fetch_array($result)){
     echo "<tr>";
     echo "<td width='15' height='12'><img src='/blog_article/image/home2.gif' width='14' height='14'></td>";
     echo "<td width='540' height='12'>$myrow[id] $myrow[tradetype] $myrow[address] $myrow[wuye]($myrow[housetype])<font >[$myrow[date]]</font>";
     echo "</td>";
     echo "<td width='75' height='12'><a href='/blog_article/view_d/code/$myrow[code].html' target='_blank'>详细内容</a></td>";
     echo "</tr>";
         }
       }
     else echo "<tr><td><div align='center'><img src='/blog_article/image/sorry.gif'><br><br>没有找到满足你条件的记录</div></td></tr>";
     }

         $prev_page=$page-1;
         $next_page=$page+1;
         echo "<div align='center'>";
         echo " 第".$page."/".$page_count."页&nbsp";
         if ($page<=1){
             echo "|第一页|";
            }
         else{
             echo "<a href='/blog_article/$PATH_INFO/page/1.html'>|第一页|</a>";
             }
         echo " ";
         if ($prev_page<1){
             echo "|上一页|";
            }
         else{
             echo "<a href='/blog_article/$PATH_INFO/page/$prev_page.html'>|上一页|</a>";
             }
         echo " ";
         if ($next_page>$page_count){
             echo "|下一页|";
             }
         else{
             echo "<a href='/blog_article/$PATH_INFO/page/$next_page.html'>|下一页|</a>";
              }
         echo " ";
         if ($page>=$page_count){
             echo "|最后一页|";
               }
         else{
             echo "<a href='/blog_article/$PATH_INFO/page/$page_count.html'>|最后一页|</a>";
             }
        echo "</div>";
    }
     else{
         echo "<p align='center'>现在还没有房屋租赁信息!</p>";
       }
   echo "<hr width="100%" size="1">";
  ?>
    </table>
