I have a very big html form (containing table with rows, which contain multiple inputs), which i need to submit to PHP script via POST request. The problem is some values don't come through and are absent in PHP's $_POST superglobal.
I checked (using Firebug extension) that the values are actually sent to server by the browser.
$_POST gets populated, but some values are just missing.
I checked what is raw request using:
$raw_post = file_get_contents('php://input');
and the string returned has the values. They are just not parsed into $_POST array. The strange thing i noticed is, it seems that the php://input values are cut after some length, and rest of the string does not come through to $_POST.
I thought about post_max_size and memory_limit and set them to large values:
but according to php documentation $_POST should not contain any values if request made is bigger than post_max_size.
memory_limit = 256M post_max_size = 150M
Due to big size of form and request I cannot post it here, but i can post php script i used to debug the problem:
var_dump($file = file_get_contents('php://input')); var_dump($_POST); //... then i parsed the $file
Server version: Apache/2.2.9 (Debian)
PHP version: PHP 5.3.2-0.dotdeb.2
Can enyone explain reason of such strange PHP behaviour, and what should i do (change php settings, code?) to use $_POST array while processing form?
EDIT: To be clear: not only the values are missing. $_POST does not contain these keys either.
e.x. fragment of raw post:
Key 't_dodparam' is in post and it has key 198. The rest of parameters are missing (e.x. t_dodparam2 is in post, but it has no such key as 198, and there is no such key as n_wartosc in $_POST)
PHP modifies fields containing the characters space, dot, open square bracket and others to be compatible with with the deprecated register_globals
you can find a lot of workarounds in the comments here: PHP: Variables From External Sources
