PHP Session Data Not Being Stored -

I am creating a login system, but when a user logs in, then it actually stores any data I do not want to do it in session. I also checked the session file, and it was empty. I have session_start (); On all the pages what I was doing wrong is the code for two main pages.

Login Code:

  & lt;? If ($ DEBUG == true) {error_reporting (E_ALL); } "Header.php" is required; Need_once "dbinterface.php"; Need_once "user.class.php"; Need_once "config.inc.php"; $ Db = new db ($ db ['host'], $ db ['user'], $ db ['pass'], $ db ['database']); $ U_result = $ db- & gt; Play ("Choose user_id from user where user_name = '". $ Db-> escape ($ _ POST [' user_name ']). "'"); If ($ u_result == incorrect) {$ url = 'Location: error.php? Id = 8 '; Header ($ url); } If (count ($ u_result) & lt; 1) {$ url = 'Location: error.php? Id = 3 '; Header ($ url); } $ User = new user ($ u_result [0] ['user_id']); If ($ user- & gt; match_password ($ _ POST ['pass']) == true) {$ _SESSION ['authenticated'] = true; $ _SESSION ['user_id'] = $ u_result [0] ['user_id']; $ _SESSION ['user'] = $ user; } And {$ url = 'location: error.php? Id = 4 '; Header ($ url); } Session_write_close (); Header ('location: index.php'); ? & Gt;  

Title included in each page:

A small background:

• Windows 7 (also tried on Windows
• Server 2008, but currently 7) PHP
• A 5 ​​locally hosted problem exists
• Everyone exists for all issues
• Browser

< / Div>

Here are some suggestions (I do not really know what's going on and / or why, so they only suggest ; Maybe a problem will solve ^ ^)

First of all, some questions:
(if they do not do any of these suggestions at least)

• Which version of PHP / Apache are you using?
• Are you on Windows? Linux?
• If you are on your "Production" server, what is the hosting service? Maybe something special about it?
• Is there a problem for every one ?
  • Is there always a problem when you are browsing the site?
  • Is it still present when you are accessing the site from another browser?
  • Computer?
  • If you use something like var_dump ($ _ session); Die; What does the session set in the session at the end of the script, what does it give?

  
  

  First thought: If you set some headers to disable caching by the browser?
  Content like this, for example:

    session_start (); Header ("Cache-Control: Private");  

  
  The second idea (at least if you are on windows): Did you try to deactivate the antivirus / firewall? Is the session cookie created correctly in the client's browser?
  If you are using subdomain (or not): Is the cookie domain right? What's the end date about this?

  
  Third opinion:

  • You have said that error_reporting is set to E_ALL , which is good
  • What about display_errors ? Is it set up so that errors can be displayed?
  • Is something interesting in PHP / Apache's error_log ?

  
  Another one: Are you sure that there is nothing in output before session_start ? Not even white places?

  
  Yet another: Are you sure about permissions on directory / files?

  • Permission to write in a directory means that you can create new files, and / or delete old
    • But, if I miss it correctly You can not modify them
  • To modify the files, you should also have the facility of writing on files
    • Actually, your webserver should Access to files is required. ^^

  What is the permission on the directory of the session and on the (empty) files?

  
  I am starting to run away from ideas ... with some luck, maybe one of them would be right ... or help you figure out what will be right!

  Good luck!
