RE: [PHP-WIN] Passing an Array in HTML

You can pass array data by adding it to the form (probably not a good practice, I would choose sessions to pass the data, but incase you have some need that is ok, try the following); // To add the data to your form; Foreach($data_old as $k => $v) echo "<input type=hidden name=\"dataold[".$k."]\" value = \"".$v."\">\n"; // to get the data returned from the form add the following to the module specified in the form action field $data_old = $_POST["dataold"]; // $data_old now contains the array contents Haven't tried this but I suspect it should work; anyone aware of a limit on the number of hidden elements in a form?
