Passing on javascript values to PHP variable?

The javascript code below adds values "sh" and "ww" for the text box named "shipping" and updates instantly when the user selects the location to ship to.


document.autoSumForm.shipping.value = (sh * 1) + (ww * 1);

I would like to pass that value on to a PHP variable. Can this be done?

Thanks

You would need to either submit the form to a php script:

<form action="yourpage.php">

or redirect to a php script using something like this:

window.open("yourpage.php?shipping="document.autoSumForm.shipping.value,"newWindow");

Then in your php script use:

$input = $_REQUEST['shipping'];

The input variable would then contain the shipping value from your form.

Ok thanks pccode....

I got it to work with code #1 and #3. And I will look into code #2 later on. I'm building a PHP, MySQL and Javascript shopping cart from scratch.

You could also store your calculated value as a 'hidden' type of input field and have it get passed along as a $_POST[] value...
