[mapserver-users] passing arrays betn. php and javascript

[Stephen Woodbridge]

Pushkar,

Your php writes the page that is sent to the browser (or can write it)
so just have your php output code to load a javascript array with
values. let the user play with the values and when you are ready to
refresh the display using the new values have your javascript assign the
values to hidden form fields and post the form back to php with the
submit button. You can use an onSubmit() javascript function to trap the
users refresh click and then update the form fields
