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 "一个月慎蔽内":
$query.=" &&TO_DAYS(NOW()) - TO_DAYS(date)<=30"
break
case "宽睁州三个月内":
$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($result)){
echo "<tr>"
echo "<td width='15' height='12'><img src='image/home2.gif' width='14' height='14'></td>"
echo "<td width='540' height='12'>$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></td></tr>"
}
$prev_page=$page-1
$next_page=$page+1
echo "<div align='center'>"
echo " 第".$page."/".$page_count."页&nbsp"
if ($page<=1){
echo "|第一页|"
}
else{
echo "<a href='$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=$page_count'>|最后一页|</a>"
}
echo "</div>"
}
else{
echo "<p align='center'>现在还没有房屋租赁信息!</p>"
}
echo "<hr width="100%" size="1">"
?>
</table>
很简单,判断URL的参数(他的url是伪的),比如?pam1=beijing&pam2=zufang那么php代码里面:判断pam1参数是否存在,存在的话,sql语句内where条件就添加pam1=beijing,
把sql语句内的where后面条件设为变量,如$where,通过判断url参数改变这个变量就实现了多条件复合查询了!
希望对你有帮助!
