Yes,

you can do that. Just make two inputs with a name in your form in the 
php file (e.g. <input .... name=javasX>).

I don't know what your does exactly but you can asign the Values from 
your coordinates to the html/php inputs (e.g. 
document.yourform.javasX.value = someXcoordinate). Notice that you 
should know what coordinates you get from the script (pixel, position of 
start point).

If the from gets submitted you can use this in php script. If your form 
uses POST then it could look like:

     if (isset($HTTP_POST_VARS["javasX"]))
     {
       $click_x = $HTTP_POST_VARS["javasX"];
     }

Now you can use this coordinates in php and do what you want to do.
