Sessions not working ???

Vivid Lust · February 19, 2008

Please help.

Here are my codes:

Login:

<?php
//...
$myusername = $_POST['myusername'];
$mypassword = $_POST['mypassword'];
$sql = "SELECT *, member FROM $tbl_name WHERE email='$myusername' and password='$encrypt'";
$result = mysql_query($sql);
$count = mysql_num_rows($result);
if($count==1){
$row = mysql_fetch_assoc($result);
$_SESSION['myusername'] = $myusername;
header("location:profile.php?member=".$row['member']);
}
else{
echo "Wrong Username or Password";
echo "<br>";
echo "<b>";
}
?>

Check session to display links:

<?php
if(isset($_SESSION['myusername']))
echo "<a href=logout.php>Log Out</a>";
else
echo "<a href=login.php>Click here to login!</a>";
?>

Thats loads in advanced!!!!!

You need to add session_start(); at the top of the code.

I do but it says:

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/jacsta/public_html/site/profile.php:20) in /home/jacsta/public_html/site/menu.php on line

When he said top of code, he means the first line of code after <?php

Vivid Lust · February 19, 2008

yes i know.

menu.php:

<?php
session_start();
if(isset($_SESSION['myusername']))
echo "<a href=logout.php>Log Out</a>";
else
echo "<a href=login.php>Click here to login!</a>";
?>

Which is called in profile.php

if it's included in another file, then it needs to be at the top of the other file.

session_start must be before any output.

smithmr8 · February 19, 2008

If you've put 'session_start()' at the top of both login.php and the pages which you need to use the session details.. then it should be working.

Vivid Lust · February 19, 2008

Dont worry

Vivid Lust · February 19, 2008

Ok, theres no error, although the text is always click here to login, although i logged in ???

rhodesa · February 19, 2008

Are you sure the login script is working properly? I notice in your SELECT statement you use "password='$encrypt'". Where is $encrypt getting set?

also, after your header('location...'); put an exit;

smithmr8 · February 19, 2008

That would mean that $_session['myusername'] has not been assigned.

Vivid Lust · February 19, 2008

I think it will be easier to post my full scrips as follows:

<?php
$host = "localhost";
$username = "************";
$password = "************";
$db_name = "************";
$tbl_name = "members";
$encrypt = md5($mypassword);

mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");

$myusername = $_POST['myusername'];
$mypassword = $_POST['mypassword'];
$sql = "SELECT *, member FROM $tbl_name WHERE email='$myusername' and password='$encrypt'";
$result = mysql_query($sql);
$count = mysql_num_rows($result);
if($count==1){
$row = mysql_fetch_assoc($result);
$_SESSION['myusername'] = $myusername;
header("location:profile.php?member=".$row['member']);
}
else{
echo "Wrong Username or Password";
echo "<br>";
echo "<b>";
}
?>

<?php
session_start();
include ("counter.php");
$dbhost = 'localhost';
$dbuser = '************';
$dbpass = '************';
$conn = mysql_connect($dbhost, $dbuser, $dbpass) or die ;('Error
connecting to mysql');
$dbname = '************';
mysql_select_db($dbname);
$query = mysql_query( "SELECT member, fname, nick, dp, sname, relationship, mood, views, description, description2, country, joined, gender, dob FROM members WHERE member = '{$_GET['member']}'" )
or die(mysql_error());
$row = mysql_fetch_assoc($query);
$memberid = $_GET['member'];
function birthday ($birthday) { list($year,$month,$day) = explode("-",$birthday); $year_diff = date("Y") - $year; $month_diff = date("m") - $month; $day_diff = date("d") - $day; if ($month_diff < 0) $year_diff--; elseif (($month_diff==0) && ($day_diff < 0)) $year_diff--; return $year_diff; }

That should clear alot of things up.

$_SESSION['myusername'] = $myusername;

Your declaring a session variable, without an open session in progress.

Put in : session_start(); between <?php and $host

rhodesa · February 19, 2008

also, you need to have

$encrypt = md5($mypassword);

after this line

$mypassword = $_POST['mypassword'];

Vivid Lust · February 19, 2008

Thanks, its working

How could i compare the value of the session to the one in the database to get member info.

Thanks.

duclet · February 20, 2008

Well, if you stored the username or user id, then you can always make another call to MySQL to retrieve the member information.

<?php
$sql = sprintf('SELECT * FROM user_table WHERE username = "%s" LIMIT 1;',
               $username);
$query = mysql_query($sql) or die('SQL: '.$sql.'<br />Error: '.mysql_error());

// Now use the result
?>
