Question?

[per1os]

I will test it out when I get home the exact code on my server. If I can do it on my server than there is something definitely wrong at the server level and not at the script. Other than a few spots that could use improvement (which shouldn't effect the session) I do not see anything that would be throwing the sessions out of whack.

Why won't the session register in the user_auth.php file?

 

Ok, I will brake the code down.

I am asking for someone to point out the problem!

 

Note: Follow the order in which there in.

 

The user is prompted to log in from login.php.

The form is submitted to member.php. There is a

call to a function called login($user_name,$password)

which is defined in user_auth.php. The other two files

are the database file and container_fns.php. The structure

of how the database is set up is in the database file.

 

login.php

<form method="POST" action="member.php">
<h1 align="center">Test log in </h1>
<table border="1" align="center">
<tr>
<td>Username:</td>
<td><input type="text" name="user_name" /></td>
</tr>
<tr>
<td>Password:</td>
<td><input type="password" name="password" /></td>
</tr>
<tr>
<td colspan="2" align="center"><input type="submit" name="submit" value="Submit" /></td>
</tr>
</table>
</form>

 

member.php

<?php
session_start();
require_once("container_fns.php");

if (isset($_POST['submit']))
#They have just tried logging in
{
$user_name= trim($_POST['user_name']);
$password = trim($_POST['password']);

#Checks that username is in database and password is correct 
$result = login($_POST['user_name'], $_POST['password']);

// If user isn't valid
if(!$result){
      // unsuccessful login
   echo "<p class='genmed'>You could not be logged in. 
   You must be logged in to view this page. <br />
   $user_name $password</p>";
   exit;
}   
   
// if they are in the database register the user id
$valid_user = $user_name;
$_SESSION['valid_user']= $valid_user; 
  
$password_str = $password;
$password_str = md5($password_str);
$_SESSION['password'] = $password_str;
  	   
}// end of submit

// connect to database 
// retrieve default image
$sql = "SELECT default_image FROM members_info 
WHERE members_id='{$_SESSION['memberid']}'";

if ($result = mysql_query($sql)) {
   if (mysql_num_rows($result)) {
      while ($row = mysql_fetch_assoc($result)) {

It's your server. The code works just fine.

 

        echo "<img src=\"http://localhost/trium/$default_image\" height=\"120\" width=\"120\" alt=\" \" />";
echo "<br />" . $_SESSION['memberid'] . "<Br />" . $_SESSION['last'];

 

That was the only part I changed to show the image, memberid from session and last from session.

 

See attached screenshot.

Whats wrong with that? I can test on a live server if you want, I guarantee it will work on my server as I have my localhost setup the exact same. If you want me to, I will.

 

[Trium918]

Yea, but why isn't it working on my server? I need some

help figuring this out.

[per1os]

Post your php.ini settings.

[Trium918]

Post your php.ini settings.

 

php.ini file Attached.

The only difference I saw in the session portion was:

 

session.use_only_cookies = 1

 

that, yours is defaulted to 0, where as mine was set to 1. Whether that should or would make a a difference I doubt it.

 

You could try setting the domain for the session cookie bit via www.php.net/ini_set

 

Other than that I have no clue, all I can see if that it worked for me.

[Trium918]

What version of apache are you running?

The thing that I donnot understand is why

would redundant code work? The sessions

are being register when I am using the script

below.

 

<?php
function login($user_name, $password)
// check username and password with db
// if yes, return true
// else return false
{
  // connect to db
  $conn = db_connect();
  if (!$conn)
    return 0;

  $result = mysql_query("SELECT * FROM members_info WHERE  user_name='$user_name' 
  													AND password=MD5('$password')");

  if ($result){
  
  $sql1="SELECT members_id,last_visit FROM members_info WHERE user_name='$user_name'";
  $result1=mysql_query($sql1);
  $row=mysql_fetch_assoc($result1);
  
  $last=$row['last_visit'];	
      $membersid=$row['members_id'];
  
      $_SESSION['membersid'] = $membersid;
  
  #Display date as 5/8/2007 format
  $last = date('n/d/Y', strtotime($last));  
  
  $_SESSION['last']=$last;   //use the session variable to hold the previous last visit date.


  $sql="UPDATE members_info SET last_visit=NOW() WHERE user_name='$user_name'";   //now only update it
  $result2=mysql_query($sql);  
  }
  
  if (!$result)
     return 0;
  
  if (mysql_num_rows($result)>0)
     return 1;
  else 
     return 0;
}
?>

Apache 2.0

[Trium918]

Ok, frost110, I tried the script on Linux server and for some reason the

session still is registering. What could be the problem? What do you suggest

I try? 

[per1os]

I dunno man, you posted all relevant code, it seems your settings are alright. Really a default installation of PHP and Apache should work just fine. I cannot re-create the error on my box, linux or windows.

 

Is there any portion of code that is being ran that you have not posted? Are you using Header redirects, if you are using a header redirect try a javascript or meta instead.

 

Other than that you stumped me man, as it works fine on my linux and windows servers.

Yes, I am using a redirect, but I will have to post it when I get home. I donnot have the

code with me.
