Just fought through something like this today... <form id="styles_saver" ...> <input type="submit" onclick="save_styles();" /> </form> <script type="text/javascript"> function save_styles(){ var div; var styles_saver=document.getElementById('styles_saver'); foreach(divs as d){ div = divs[d]; styles_saver.innerHTML += '<input type="hidden" name="style["' + d + ']" value="' + div.style '" />'; } styles_saver.submit(); </script> This is all JS, obviously... > What are the technologies IF there are any and what should i look up > to find > docs that cover this type of datatransfer ie: javascript->php. So now in the PHP part, to force this at least nominally on-topic, you have a nice array in $_POST['styles'] with an index by div in order, that you'd process like any $_POST value which is an array: if (isset($_POST['styles']) && is_array($_POST['styles'])){ foreach($_POST['styles'] as $d => $style){ //do something with div's $style, indexed by $d } } You could presumably get each div's id with div.id or somesuch, and use that instead of 'd' above. -- Some people have a "gift" link here.
