查询文件（search.php）
一、生成查询语句：

复制代码 代码如下:
<?
$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：
复制代码 代码如下:
<?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($result)){
echo "<tr>";
echo "<td width="15" height="12"><img src="image/home2.gif" width="14" height="14"></td>";
echo "<td width="540" height="12">$myrow[id] $myrow[tradetype] $myrow[address] $myrow[wuye]($myrow[housetype])<font style="font-size:9pt">[$myrow[date]]</font>";
echo "</td>";
echo "<td width="75" height="12"><a href="view_d.php?code=$myrow[code]" target="_blank">详细内容</a></td>";
echo "</tr>";
}
}
else echo "<tr><td><div align="center"><img src="image/sorry.gif"><br><br>没有找到满足你条件的记录</div>& lt;/td></tr>";
}
$prev_page=$page-1;
$next_page=$page 1;
echo "<div align="center">";
echo " 第".$page."/".$page_count."页 ";
if ($page<=1){
echo "|第一页|";
}
else{
echo "<a href="$PATH_INFO?page=1">|第一页|</a>";
}
echo " ";
if ($prev_page<1){
echo "|上一页|";
}
else{
echo "<a href="$PATH_INFO?page=$prev_page">|上一页|</a>";
}
echo " ";
if ($next_page>$page_count){
echo "|下一页|";
}
else{
echo "<a href="$PATH_INFO?page=$next_page">|下一页|</a>";
}
echo " ";
if ($page>=$page_count){
echo "|最后一页|";
}
else{
echo "<a href="$PATH_INFO?page=$page_count">|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">";
?>
