Question

My databse is:

CREATE TABLE `user` (
  `id` int(4) NOT NULL auto_increment,
  `name` varchar(77) NOT NULL,
  `pass` varchar(77) NOT NULL,
  `datetime` varchar(22) NOT NULL,
  `level` varchar(33) NOT NULL,
  PRIMARY KEY  (`id`)
) ENGINE=MyISAM  DEFAULT CHARSET=utf8 AUTO_INCREMENT=6 ;

INSERT INTO `user` VALUES (1, 'majid', '123', '2012-04-16', 'admin');
INSERT INTO `user` VALUES (2, 'feras', '123', '2012-04-15', 'gs');
INSERT INTO `user` VALUES (3, 'sami', '123', '2012-04-12', 'gs');
INSERT INTO `user` VALUES (4, 'rashed', '123', '2012-04-09', 'gs');
INSERT INTO `user` VALUES (5, 'saad', 'dfd', '2012-04-13', 'bb');

My search page is a form with three dropdown lists… first for name, second for pass and third for level.

Now, if I choose one drop list it will gives me a good result, but if I choose two or more lists it does not give me anything.

How can I make all that dropdown lists act like a filter for a specific result?
Like “all pass (123) and level (gs)”

My query is:

$name= $_GET['name'];
$pass= $_GET['pass'];
$level= $_GET['level'];
mysql_select_db($database_sqltest, $sqltest);
$query_Recordset1 = "SELECT * FROM user WHERE '$name' OR pass LIKE '$pass' OR level LIKE '$level'";
$Recordset1 = mysql_query($query_Recordset1, $sqltest) or die(mysql_error());
$row_Recordset1 = mysql_fetch_assoc($Recordset1);
$totalRows_Recordset1 = mysql_num_rows($Recordset1);

You need to use AND operator instead of OR to increase specificity and limit the query. I’ve added % signs (wildcards) so that a search for “12” would match pass “123”. You can remove them if you won’t want that functionality.

$query_Recordset1 = "SELECT * FROM user WHERE `pass` LIKE '%$pass%' AND `level` LIKE '%$level%' AND `name` LIKE '%$name%'";
