satishgadhave Posted January 22, 2009 Share Posted January 22, 2009 Hi, try using this code to echo submitted values (I have changed $$field to $field): if (isset($_POST['assign_x'])) { $citya = array(); foreach ($_POST as $field => $value) { $field = mysql_real_escape_string(trim($value)); echo $field . '<br />'; } } Quote Link to comment Share on other sites More sharing options...
scarhand Posted January 24, 2009 Author Share Posted January 24, 2009 i sorted it out it was because i was using "value" instead of "name" for the checkboxes you changing "$$field" to "$field" would accomplish nothing. in fact, it would render any variables i used below useless.
