PHP实现多条件查询实例代码_php实例

查询文件（search.php）
一、生成查询语句：

 <BR><? <BR>$conn=mysql_connect("localhost","root",""); <BR>$db=mysql_select_db("lingyun"); <BR>$query="select * from message where tradetype='".$tradetype."'"; //交易类型，如出租，出售 <BR>$SQL=$SQL . "wuye='" . $wuye . "'"; <BR>if($housetype!="不限"){ <BR>$query.=" && housetype='".$housetype."'"; //房屋类型，如二室一厅，三室二厅 <BR>} <BR>if($degree!="不限"){ <BR>$query.=" && degree='".$degree."'"; //新旧程度 <BR>} <BR>if($wuye!="不限"){ <BR>$query.=" && wuye='".$wuye."'"; //物业类型 如住房，商铺 <BR>} <BR>if($price2!=""){ <BR>switch($price1){ <BR>case "大于": <BR>$query.=" && price>'".$price2."'"; //价格 <BR>break; <BR>case "等于": <BR>$query.=" && price='".$price2."'"; <BR>break; <BR>case "小于": <BR>$query.=" && price<'".$price2."'"; <BR>break; <BR>} <BR>} <BR>if($area2!=""){ <BR>switch($area1){ <BR>case "大于": <BR>$query.=" && area>'".$area2."'"; //面积 <BR>break; <BR>case "等于": <BR>$query.=" && area='".$area2."'"; <BR>break; <BR>case "小于": <BR>$query.=" && area<'".$area2."'"; <BR>break; <BR>} <BR>} <BR>switch($pubdate){ //发布日期 <BR>case "本星期内": <BR>$query.=" && TO_DAYS(NOW()) - TO_DAYS(date)<=7"; <BR>break; <BR>case "一个月内": <BR>$query.=" && TO_DAYS(NOW()) - TO_DAYS(date)<=30"; <BR>break; <BR>case "三个月内": <BR>$query.=" && TO_DAYS(NOW()) - TO_DAYS(date)<=91"; <BR>break; <BR>case "六个月内": <BR>$query.=" && TO_DAYS(NOW()) - TO_DAYS(date)<=183"; <BR>break; <BR>} <BR>if($address!=""){ <BR>$query.=" && address like '%$address%'"; //地址 <BR>} <BR>if(!$page){ <BR>$page=1; <BR>} <BR>?> <BR>

二、输出查询结果：

 <BR><?php <BR>if ($page){ <BR>$page_size=20; <BR>$result=mysql_query($query); <BR>#$message_count=mysql_result($result,0,"total"); <BR>$message_count=10; <BR>$page_count=ceil($message_count/$page_size); <BR>$offset=($page-1)*$page_size; <BR>$query=$query." order by date desc limit $offset, $page_size"; <BR>$result=mysql_query($query); <BR>if($result){ <BR>$rows=mysql_num_rows($result); <BR>if($rows!=0){ <BR>while($myrow=mysql_fetch_array($result)){ <BR>echo "<tr>"; <BR>echo "<td width='15' height='12'></td>"; <BR>echo "<td width='540' height='12'>$myrow[id] $myrow[tradetype] $myrow[address] $myrow[wuye]($myrow[housetype])<font style='font-size:9pt'>[$myrow[date]]</font>"; <BR>echo "</td>"; <BR>echo "<td width='75' height='12'>详细内容</td>"; <BR>echo "</tr>"; <BR>} <BR>} <BR>else echo "<tr><td><div align='center'><br><br>没有找到满足你条件的记录

& lt;/td>

“;
}
$prev_page=$page-1;
$next_page=$page 1;
echo “

}
else{
