$rs_result = mysql_query ($sql);
$num_rows = mysql_num_rows($rs_result);
$query = mysql_query("SELECT * FROM subscribers2 WHERE type  = '%$type%' AND address = '%$address%' AND bedrooms = '%$bedrooms%' AND min as '%$price%' AND max as '%$price%' "); 



$rs_result = mysql_query ($sql);
$num_rows = mysql_num_rows($rs_result);
$query = mysql_query("SELECT * FROM subscribers2 WHERE type  LIKE '%$type%' AND address LIKE '%$address%' AND bedrooms LIKE '%$bedrooms%' AND min as '%$price%' AND max as '%$price%' "); 
$number=mysql_num_rows($query);

Answer 1

当您将查询字符串注释掉时，它看起来像您的查询$sql。

但这只是3个mysql错误中的一个。

您将使用mysql_error as documented here找出错误。

您还应该查看SQL注入，您的参数将直接通过POST传递到数据库级别，这会使您的服务器数据库全开。

搜索多个标准mysql
