Some of the data which I take from the user depends upon the selection of the data prior to the some inout boxes eg.batchno select box to be shonly when proudct code is selected and the for the query also the batchno selection query will depend upon the product code selected then in thatb case how do I do it without passing it in the url

You can have multiple hidden fields in the form.

See example:

<form name="myhiddenform" method="post">
<input type="hidden" name="param1" id="param1">
<input type="hidden" name="batchno" id="batchno">
<input type="hidden" name="proudctcode" id="proudctcode">
</form>

<input type="button" onclick="submitForm()" value="submit">

<script>
	function submitForm()
	{
		//window.location = "mypage.php?param1=xyz";
		document.getElementById("param1").value="xyz";
		document.getElementById("batchno").value="abc";
		document.getElementById("proudctcode").value="123";
		document.myhiddenform.action = "mypage.php";
		document.myhiddenform.submit();
	}
</script>

Select allOpen in new window

Will try n see if this fits my requirement and get back

sorry for late reply but was cuaght up with something else

But if the value in the second select box depends upon the first input box i.e the first input box value entered is used to query the table on the database server then how do i get it

I dont know your actual Objective, but what is the need for posting values using javascript?

If you are using the <form> tag with POST method. Then nothing to worry. Every HTML Control with an ID specified will be automatically posted the specified target php file.
check
<form name="YourForm" method="post" action="THEDESTINATIONFILE.php">

in THEDESTINATIONFILE.PHP , simply put
if(isset($_POST)){
echo '<pre>';
print_r($_POST);
echo '</pre>';
}
