Assign Value To Unchecked Checkbox

السلام عليكــم ورحمـة الله وبركاتــه ،،

اريد اعطاء قيمة للتشيك بوكس عندما يكون unchecked

حاولت استخدام دالة جافا سكريبت (check)

لكن لم تنجح معي

اخر رسالة يقف عندها (minute)

ولا يعطي رسالة (work again)

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<script language="javascript">
function checkCheckBoxes(form) 
	{
	alert(" will work!");
	for(var i=0; i<4; i++)
		{
			alert("minute");
			if (document.langu.view.checked == false )			
			{	
				alert("will work again");
				document.langu.view.value =0;		
			}	

		}
	}

</script>

<?

if($_REQUEST["hed"]!="")
	{
		$property = array("monthly_bandwidth","disk_space","monthly_price","yearly_price");
		$lang=$_REQUEST["lang"];
		$offer=$_REQUEST["offer"];
		$view=$_REQUEST["view"];

		$vall=$_REQUEST["vall"];




		for($i = 0; $i < 4; $i++)

		{
	echo 	$qq="insert into hosting_offers(hosting_offer_id,name,value,language,disply) values ('$offer','$property[$i]','$vall[$i]','$lang','$view[$i]' )";		
		$ss= $obj->Get_Query($qq);

		} 

} 

if(!isset($lang))
{
$lang='e';
}
