Error in SQL Syntax HELP!!!

Posted on 16th Feb 2014 by admin

I have this page:

Code: <?php

session_start();

//connect to server and select database
$conn = mysql_connect("localhost", "root", "")
or die(mysql_error());
$db = mysql_select_db("smrpg", $conn) or die(mysql_error());

//show scouts characters
$get_scouts = "select * from scouts where username = '".$_SESSION['userName']."'";
$get_scouts_res = mysql_query($get_scouts, $conn) or die(mysql_error());
while ($list_scouts = mysql_fetch_array($get_scouts_res)) {
$identity = ucwords($list_scouts['identity']);
$topic_id = $list_scouts['id'];
echo "<ul class="character_list"><li><a href="fight.php?identity=$identity">$identity</li></ul> ";
}
?>

And it goes to this page:

Code: <?php

session_start();

//connect to server and select database
$conn = mysql_connect("localhost", "root", "")
or die(mysql_error());
$db = mysql_select_db("smrpg", $conn) or die(mysql_error());

//check for required info from the query string
if (!$_GET['identity']) {
header("Location: train_fight.php");
exit;
}

//get derived values

$derived = "select * from derived_values where identity = $_GET[identity]";
$derived_res = mysql_query($derived, $conn) or die(mysql_error());

$display_block = "<ul>";

while ($derived_info = mysql_fetch_array($derived_res)) {
$derived_id = $derived_info['id'];
$derived_identity = $derived_info['identity'];
$derived_health = $derived_info['health'];
$derived_energy = $derived_info['energy'];
$derived_acv1 = $derived_info['acv1'];
$derived_acv2 = $derived_info['acv2'];
$derived_dcv1 = $derived_info['dcv1'];
$derived_dcv2 = $derived_info['dcv2'];
$derived_total_cp = $derived_info['total_cp'];

$display_block .= "<li>$derived_identity</li>";

}

$display_block .= "</ul>";

?>

But I am getting this error:

You have an error in your SQL syntax; check the manual that correspondsto your MySQL server version for the right syntax to use atline 1

What am I doing wrong here? If I change my where statement or take it out, it is displaying the information, but I can't figure out what's wrong with my where statement or where I'm getting my "identity" from. Something's wrong but I can't find it. Can anyone help?
