714Part IVConnectionsPassing data back to PHP from JavaScriptFinally, we close the data loop by passing form values back to PHP with JavaScript. Listings38-5, 38-6, and 38-7 use JavaScript to force at least one check box to be checked at all times. Inaddition, it passes an array to a PHP script. We ve chosen to use frames here to maximize thespeed of the changes, and we wrote all values out by hand for clarity, rather than assemblingthem dynamically from a data source.
