Passing variables from Javascript to PHP

tiger

I hope this is the right place to ask this question...

How do I pass variables between javascript and php?

Here's the situation...

I've created a website entirely in PHP, I need to delete a record from the MySQL database, but I want to ask the user if their sure they want to delete it, before actually deleting it.

I don't know how to create a dialoge box in php(if there's a way, that would be the best solution), so I've created the dialoge box in javascript but don't know how to pass the users reponse back into the php code.

Please help.
Thanks in advance!

If you're using a form on the page you can have a hidden field that you set the value of with javascript, or even have no submit button on the form and only let the form be submitted via javascript.

Exactly how can the variable be assigned?

i try:

<SCRIPT LANGUAGE="JavaScript">
<!--

function RecordVariable(callingElement) {
<?php $COD=echo"callingElement.elements[0].value;";?>
}

// -->
</SCRIPT>

but did not work , any ideas?
Thank´s in advance

Here's what I ended up doing:

I have a file called scripts.php that I include in my header. Here is the code for the dialog box:

function ConfirmDelete()
{
	if(confirm("Are you sure you want to delete this record?") == true)
	{
		document.location.href=document.location+"&DeleteResponse=Confirm&Action=View";
	}
}

</script>

Then, within my original page code:

	if($Action == "DeleteRecord")
	{
		if($_SESSION['CanDeleteCompanies'] == 1)
		{
			$Action = "View";
			echo '<script 				language="javascript">ConfirmDelete()</script>'."\n";
		}
	}

	if($DeleteResponse == "Confirm")
	{
		if($_SESSION['CanDeleteCompanies'] == 1)
		{
			DeleteCompanyRecord($RecordNum);
			$DeleteResponse = '';
		}
	}

Hope this helps...
