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": 
$query.=" && pricebreak; 
} 
} 
if($area2!=""){ 
switch($area1){ 
case "大于": 
$query.=" && area>'".$area2."'"; //面积 
break; 
case "等于": 
$query.=" && area='".$area2."'"; 
break; 
case "小于": 
$query.=" && areabreak; 
} 
} 
switch($pubdate){ //发布日期 
case "本星期内": 
$query.=" && TO_DAYS(NOW()) - TO_DAYS(date)break; 
case "一个月内": 
$query.=" && TO_DAYS(NOW()) - TO_DAYS(date)break; 
case "三个月内": 
$query.=" && TO_DAYS(NOW()) - TO_DAYS(date)break; 
case "六个月内": 
$query.=" && TO_DAYS(NOW()) - TO_DAYS(date)break; 
} 
if($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:

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 "";
echo " PHP实现多条件查询实例代码_PHP教程

";
echo "$myrow[id] $myrow[tradetype] $myrow[address] $myrow[wuye]($myrow[housetype])[$myrow[date]]";
echo "";
echo "详细内容";
echo "";
}
}
else echo "

没有找到满足你条件的记录

& lt;/td>";
}
$prev_page=$page-1;
$next_page=$page 1;
echo "

";
echo " 第".$page."/".$page_count."页&nbsp";
if ($pageecho "|第一页|";
}
else{
echo "|第一页|";
}
echo " ";
if ($prev_pageecho "|上一页|";
}
else{
echo "|上一页|";
}
echo " ";
if ($next_page>$page_count){
echo "|下一页|";
}
else{
echo "|下一页|";
}
echo " ";
if ($page>=$page_count){
echo "|最后一页|";
}
else{
echo "|最后一页|";
}
echo "

";
}
else{
echo "

现在还没有房屋租赁信息!

";
}
echo "

";
