I have to disagree Ash, you can pass js variable values to PHP but only through a page load. Then you could use $_REQUEST, $_POST, $_GET to retrieve it. I have done this before.

And I am sure Ash does it on daily basis, the problem is the used therm: I want to *assign* ... not pass, assign! I am quite sure that is what he meant, since I cannot count people reading <?php ?> in the middle of the page thinking it can interact directly with nodes and javascript, and being "a new one", I think Ash replied in the correct way. Regards All true, and probably appropriate to clarify the relationship between php and js.

However, if the goal is to pre-set something in php land so you don't have to pass it with your next page navigation, you could use ajax to to pass the value to a simple php script that in turn updates a php session variable, so that it is already set when you do your next real page load. You would still be "calling a page" technically, but your current displayed page would remain in place and php would have the value available on its next page load.
