php redirect doesn't change the url -

i know common question, not find answer

i'v post.php, submit post form controller.php when goes right, in controller does:

header("location: ./post?ok=1"); 

the post inserted, , goes through line above, url in browser seems never changed, , @ end there not ok param,

i use session variable store such success/failure param, way should working

post.php:

<form action="controller" method="post">     <input name="test" value='test' type="text" />     <input type="submit" value="post"  /> </form> 

controller.php:

<?php     header("location: ./post?ok=1"); ?> 

edit 1:

header("refresh:1;url=http://localhost/test/post?ok=1"); //doesn't work better 

edit 2:

in post.php top i've put

debug("post l ".count($_post)); debug("get l ".count($_get)); 

they show 0's before submit, , 0's after also

edit3: works

was blocked by:

if ($success){     header("location: ./post?ok=1"); } header("location: ./post");  

that should be:

if ($success){     header("location: ./post?ok=1"); } else {     header("location: ./post"); }  

thx all

first of should not use $_server['http_referer'] unsafe. possible client won't send header anyway. right don't know how i'm sure used highjack site evil.

better should know form data came , redirect user there back.

by way redirect maybe don't work expected because url contain questionmark. have add more parameters & sign.

for redirect suggest http 302 found response status. have sure nothing other send out before. there must no html output or empty lines before following header line:

header("location: http://".$_server['http_host']."/your/source.form", true, 302);
