ช่วยดูโคดที่ค่ะไม่รู้มันผิดตรงไหนมันไม่ยอม insert ค่ะ แต่พอ echo $com_name มันบอกว่าเป็น Array ค่ะแต่ไม่ยอม insert

<?
for($i=0;$i<count($_POST["com_name"]);$i++) 
{ 
	$com_name = $_POST["com_name"];
	if($com_name[$i] != '') {
		$sql1="insert into parent(com_name,no_major) Values('".$com_name[$i]."','$no_major')";
                                $result=mysql_db_query($dbname,$sql1)or die(mysql_error());
                                echo $sql1;
	}
}
?>
