I am trying to protect my queries to check the user's ip address to make sure they are not banned...

 

When I comment out the if statement in $db->query the error goes away...

 

The checkIp function works in other instances, I am just trying to call it so nobody can inject things by trying to go around the actual pages...

 

my db function class looks like this:

 

class dblib {


function query($sql) {
	if ($this->checkIp($_SERVER['REMOTE_ADDR']) == true) {
		die("GH".$ip);  // Used to see if I can get that far...
		$result = mysql_query($sql) or die("Database error: " . mysql_error() . "<br /><br /><h2>SQL</h2><p>$sql</p>");

		return $result;
	}

	else
	{
		die("<h1>Banned</h1>");
	}
    }

/// .......some other functions

    function checkIp($ip) {

	$sql = "SELECT * FROM block WHERE ip='$ip' LIMIT 1 ";
	$result = $this->query($sql);

	if (mysql_num_rows($result) == 0)
		return true;
	else
		return false;
}
