I'm trying to filter the search results of my MySQL database, I am wanting to filter the results by selecting values from two drop down boxes, the first box being Club and the second being Division so I can filter the results by Division and Club.

My issue is that when I make a selection in the club field nothing happens, I can select from the Division field and the results will display the selected division but nothing happens when I select by club.

include("config.php");

    $sql = "SELECT * FROM ".$SETTINGS["data_table"]." GROUP BY club ORDER BY club";
    $sql_result = mysql_query ($sql, $connection ) or die ('request "Could not execute SQL query" '.$sql);
    while ($row = mysql_fetch_assoc($sql_result)) {
        echo "<option value='".$row["club"]."'".($row["club"]==$_REQUEST["club"] ? " selected" : "").">".$row["club"]."</option>";
    }
?>
</select>

    <label>Division</label>

  <tr>

    }
} else {
?>
<tr><td colspan="5">No results found.</td></tr>
<?php   
}
?>
</table>
<br/>
</fieldset>
</body>
</html>

UPDATE: I changed the following code from this:

if ($_REQUEST["club"]='') {
$search_string = " AND (club LIKE '%".mysql_real_escape_string($_REQUEST["club"])."%' OR (division LIKE '%".mysql_real_escape_string($_REQUEST["division"])."%')";

}

to this:

if ($_REQUEST["club"]<>'') {
    $search_club = " AND (club LIKE '%".mysql_real_escape_string($_REQUEST["club"])."%' OR (club LIKE '%".mysql_real_escape_string($_REQUEST["club"])."%')";    
}

and now it will allow me to filter by club and division but I still can't do just by club alone!

Change this:

if ($_REQUEST["club"]='') {
$search_string = " AND (club LIKE '%".mysql_real_escape_string($_REQUEST["club"])."%' OR (division LIKE '%".mysql_real_escape_string($_REQUEST["division"])."%')";

and this:

$sql = "SELECT * FROM ".$SETTINGS["data_table"]." WHERE id>0".$search_string.$search_division;

To this:

if ($_REQUEST["club"]<>'') {
    $search_club = " AND club='".mysql_real_escape_string($_REQUEST["club"])."'";   
}

And this:

$sql = "SELECT * FROM ".$SETTINGS["data_table"]." WHERE id>0".$search_club.$search_division;

And it will work!

You are using = operator in your if statements, you want to use == comparison operator like follows: 

if ($_REQUEST["club"] == '') {
    $search_string = " AND (club LIKE '%".mysql_real_escape_string($_REQUEST["club"])."%' OR (division LIKE '%".mysql_real_escape_string($_REQUEST["division"])."%')";  
}
if ($_REQUEST["division"] <> '') {
    $search_division = " AND division='".mysql_real_escape_string($_REQUEST["division"])."'";   
}

if ($_REQUEST["club"] == '' and $_REQUEST["division"] == '') {
    $sql = "SELECT * FROM ".$SETTINGS["data_table"]." WHERE club = '".mysql_real_escape_string($_REQUEST["club"])."' AND division = '".mysql_real_escape_string($_REQUEST["division"])."'".$search_string.$search_division;
}  else {
    $sql = "SELECT * FROM ".$SETTINGS["data_table"]." WHERE id>0".$search_string.$search_division;
}
