Note Submitter: davidrobinson91 at hotmail dot com ---- <?php var_dump($_POST); ?> <form action="" method="POST"> <input type="text" name="user.name" value="" /> <input type="submit" name="save" /> </form> the var_dump($_POST) will give you the result array(2) { ["user_name"]=> string(3) "abc" ["save"]=> string(32) "submit" } instead of array(2) { ["user.name"]=> string(3) "abc" ["save"]=> string(32) "submit" } There could be a string replacement before the array assignment. If we change name="user.name" to name="user..name", the $_POST will give you the result array(2) { ["user__name"]=> string(3) "abc" ["save"]=> string(32) "submit" } As a conclusion, any '.' (dot) in the name attribute will be transformed to "_" (underscore) after the assignment to the $_POST. Any clues?
