ดูโค้ดให้หน่อยค่ะ พอเวลากด Delete แล้ว มันไม่ยอมลบ ในฐานข้อมูลอ่าค่ะ

if ($TypeID>0){
$sql = "Delete from news where id_new = $id_new";
mysql_query($sql);
}

$id_new = $_POST['id_new'];
if ($id_new != ''){
$sql = "Delete from news where id_new =".$id_new;
mysql_query($sql);
}

<form id='form1' name='form1' method='post' action='ShowNews.php'>

<form id='form1' name='form1' method='post' action=''>

<?php
include("ConnectNews.php");
if ($TypeID>0){
$sql = "Delete from news where id_new = $id_new";
$qr=mysql_query($sql);
if(isset($qr)){
	echo "<script>alert('ลบข้อมูลเรียบร้อยแล้ว'); window.location='ShowNews.php';</script>";
}
mysql_query ("SET NAMES utf8") or die (mysql_errno());
$sql = "SELECT * FROM `news`";
$result = mysql_query($sql);
$totalPrice=0;
echo"<table width='50%' border='1' bordercolor='#fff' bgcolor='#34B2C9' ><tr align='center'><td><b>ลำดับ</b></td>
<td>	<b>ชื่อข่าว</td>
<td><b>ลบข่าว</b></td>
<b></b>
</td></tr>";
while($row=mysql_fetch_array($result)){
$id_new = $row["id_new"];
$head_new = $row["head_new"];
echo "<tr bgcolor='#C6EAF0' align='center'><form id='form1' name='form1' method='post' action=' '>";
echo "<td>$id_new<input name='id_new' type='hidden' value='$id_new'></td><td>$head_new</td>";
echo "<td><input type='submit' name='Delete' id='Delete' value='Delete' onclick=" ?>"return confirm('คุณแน่ใจว่าต้องการลบข้อมูลนี้หรือไม่ ? ')" /><? "/>";
echo "</td></form></tr>";
