php - $_POST does not work on the server -

i tried make little form worked fine. wanted test on server doesn't save values.

var_dump($_post); 

returns:

array(4) { ["name"]=> string(0) "" ["pass"]=> string(0) "" ["e-mail"]=> string(0) "" ["register"]=> string(12) "registieren!" } 

on local server, but

array(0) { } 

on normal server.

enable_post_data_reading 

is "on" on both.

does have ideas?

edit:

i think got error. phpinfo() returns:

request_method  post 

on local server and

request_method  

on webserver. how can change - didn't find useful stuff

here more code:

        define('url', 'http://localhost/');         define('website_name', 'project/');         define('urlgame', 'u/');         define('lang', 'en/'); 

here form doesn't work:

<form method="post" action="'.url.website_name.lang.urlgame.'register"> 

in browser looks this:

<form method="post" action="http://localhost/project/en/u/register"> 

it same stuff on server, definitions:

        define('url', 'http://yangidu.de/');         define('website_name', 'yang/');         define('urlgame', 'u/');         define('lang', 'en/'); 

and in browser looks this:

<form method="post" action="http://yangidu.de/yang/en/u/register"> 

this button (same on both versions):

<input id="submit" type="submit" name="register" value="registieren!" /> 

if type in:

var_dump($_post); 

it returns

array(4) { ["name"]=> string(3) "asd" ["pass"]=> string(3) "asd" ["e-mail"]=> string(3) "asd" ["register"]=> string(12) "registieren!" } 

on local server,

array(0) { }

on server.

i think error because request_method not same. (i got phpinfo()) on local server it's:

request_method  post 

and on server it's:

request_method      

i got error: webserver redirected me everytime , because of $_post got lost. changed action="" "real" source of website , because of website didn't reload 2 times.

anyway thank guys!
