Header ('Location: index.php'); not working.
(Sending all field shape fields using AJAX jQuery).
How to fix?
If there is a mistake when filling, then normally works

And if success happens like this:

How can I do normally? Thanks in advance!

HTML Code:

& lt; form method = "post" id = "form" action = "javascript: void (null);" ONSUBMIT = "CALL ()" & GT;
   Login
   & lt; Input Type = "text" name = "username" / & gt;
   Password
   & lt; Input Type = "Password" name = "password" / & gt;
   & lt; Button Type = "submit" name = "submit" & gt; Login & lt; / Button & gt;
& lt; / form & gt;
& lt; div id = "results" & gt; output & lt; / div & gt;

js code:

function call () {
  VAR MSG = $ ('# Form'). Serialize ();
  $.ajax ({
    Type: 'Post',
    URL: 'login.php',
    Data: MSG,
    SUCCESS: FUNCTION (DATA) {
      $ ('# Result'). HTML (DATA);
    },
    ERROR: FUNCTION (XHR, STR) {
      Alert ('An error occurred:' + xhr.responsecode);
    }
  });
}

php code:

& lt;? php
include 'core / init.php';
If (empty ($ _ post) === FALSE) {
  $ username = $ _post ['username'];
  $ password = $ _post ['password'];
  If (Empty ($ UserName) === True || Empty ($ password) === True) {
    $ errors [] = 'You must enter the username and password.';
  } ELSE If (User_exists ($ UserName) === False) {
    $ errors [] = 'We can't find that the username. Have you registered? ';
  } ELSE If (User_Active ($ UserName) === False) {
    $ errors [] = 'You have not yet activated your account!';
  } else {
    $ login = login ($ username, $ password);
    if ($ login === FALSE) {
      $ errors [] = 'This combination of the username or password is incorrect.';
    } else {
      $ _Session ['user_id'] = $ login;
      Header ('Location: index.php');
      exit ();
    }
  }
}
Echo Output_errors ($ errors);
? & gt;

Answer 1, Authority 100%

Replace

Header ('Location: index.php');

on

exit ("& lt; meta http-equiv = 'refresh' content = '0; url = /index.php'> ; ");

Answer 2, Authority 200%

Header ('location: /index.php');

nothing should throw anything in stdout, otherwise some browsers (Khe-Donkey-Khe) may think that the title is erroneous.

for light reading.
