PHP - Session_start() Problem In Localhost
this problem really drives me crazy..hope that anyone could help.
I left my page only with <?php session_start(); ?> with no script at all..and i still got error Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at E:\Program Files\XAMPP 1.5.4\xampp\htdocs\folder\page1.php:1) in E:\Program Files\XAMPP 1.5.4\xampp\htdocs\folder\page1.php on line 2 No white space at all. I tried to upload this file into the server (not local) and no error appeared. but when i run it in my local server, error appeared. I restart my xampp so many times but still didn't fix this. what's the problem then? thanks in advance Similar TutorialsMy session start is in my session object and I include it at the top of my page prior my html code, yet I still get this warning: Code: [Select] Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /Users/Sites/writepaps/index.php:2) in /Users/Sites/writepaps/includes/functions/sessions.php on line 11 I include the object in index line 2. and line 11 is where my session start is in my construct function <?php require_once("database.php"); require_once("user.php"); class Sessions { public $logged_in = false; protected $username; protected $password; function __construct(){ session_start(); $this->check_login(); } .... Why is this happening? Hi, I am trying to send mail from my localhost but i am getting the below error ""Warning: mail() [function.mail]: Failed to connect to mailserver at "localhost" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set() in F:\test\xampp\htdocs\sendmail.php on line 42'" I am using xampp server.

I tried to have a User’s profile page only display to Users who are logged into the site, by adding session code:
if(!isset($_SESSION['username'])){
header("Location:../login");
exit();
}
like so:
<?php
if(!isset($_SESSION['username'])){
header("Location:../login");
exit();
}
if (empty($_GET['id'])) {
header("Location: " . PT_Link(''));
exit();
}
$username = PT_Secure($_GET['id']);
$user_id = $db->where('username', $username)->getOne(T_USERS);
$lists = false;
if (empty($user_id)) {
header("Location: " . PT_Link(''));
exit();
}
$pt->page_url_ = $pt->config->site_url.'/@'.$username ;
$pt->second_page = 'videos';
if (!empty($_GET['page'])) {
switch ($_GET['page']) {
case 'liked-videos':
$pt->second_page = 'liked-videos';
break;
case 'about':
$pt->second_page = 'about';
break;
case 'play-lists':
$pt->second_page = 'play-lists';
$lists = true;
break;
}
$pt->page_url_ = $pt->config->site_url.'/@'.$username."?page=".$pt->second_page;
}
$user_data = PT_UserData($user_id, array(
'data' => true
));
etc...
but was unsuccessful. The problem is although the …/@UserName no longer displays in the browser field (and redirects to the login page) (with that additional code), once logged in, the User can’t see his Profile Page either.
if(!isset($_SESSION['username'])){
header("Location:../login");
print_r($_SESSION);
exit;
}
but I see no printed results. I have tried this:
<?php
session_start();
if(!isset($_SESSION['username'])){
header("Location:../login");
exit();
}
but, when I select the drop-down menu > profile, it just seems to refresh the same page (that I'm on, and doesn't take me to the ../@chrisj profile page, as it did before I added this:
if(!isset($_SESSION['username'])){
header("Location:../login");
exit();
}
Also, the .htaccess file shows this: RewriteRule ^@([^\/]+)(\/|)$ index.php?link1=timeline&id=$1 [QSA] if that is any clue.
I went ahead and asked the developer, and he simply said:
just FYI -When a user logs in it sets the $_SESSION[‘username’] variable, id, etc.)
if(!isset($_SESSION['username'])){
header("Location:../login");
So, is there a solution that might instruct to say something like 'if already logged in go to @ the username’s profile page? something like:
if (IS_LOGGED == true) {
any additional suggestions are welcomed
For as long as I can remember, I always start my php scripts with...
// Initialize session. session_start();
On my webserver, cPanel keeps populating a error_log with the following entry..
[<date>] PHP Notice: session_start(): session has already been started - ignoring in path/to/suspect/script.php on line 10
Have I been using PHP session incorrectly all of this time?! Fwiw, I don't get this error - at least not that I know - locally in MAMP...
I have a login script that sets all my $_SESSION[] variables, it was working, now I'm redesigning, and now its not working. I can echo the variables on this page, but when it redirects to dashboard.php and I do a session_start(), nothing. It's driving me nuts. <?php require_once ('../includes/config.php'); require_once ('../includes/connect.php'); function clean($str) { $str = @trim($str); if(get_magic_quotes_gpc()) { $str = stripslashes($str); } return mysql_real_escape_string($str); } //Sanitize the POST values $login = clean($_POST['login']); $password = clean($_POST['password']); //Input Validations if($login == '') { $errmsg_arr[] = 'Login ID missing'; $errflag = true; } if($password == '') { $errmsg_arr[] = 'Password missing'; $errflag = true; } //If there are input validations, redirect back to the login form if($errflag) { $_SESSION['ERRMSG_ARR'] = $errmsg_arr; session_write_close(); header("location: ../../index.html"); exit(); } //Create query $qry="SELECT * FROM members WHERE login='$login' AND passwd='".md5($_POST['password'])."'"; $result=mysql_query($qry); //Check whether the query was successful or not if($result) { if(mysql_num_rows($result) == 1) { //Login Successful session_regenerate_id(); $member = mysql_fetch_assoc($result); $_SESSION['MEMBERID'] = $member['member_id']; $_SESSION['AGENTNAME'] = $member['firstname'] .

Does this mean I cannot place it in the middle of a HTML file? What about if I put it on line 1 of a HTML document (before the DOCTYPE! (HTML 4.01))? First want to start by saying these pages work perfect on my own hosted devel server running centos5. I am moving these to godaddy for production and am running into this error: Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/content/93/6413093/html/classifieds/login.php:7) in /home/content/93/6413093/html/classifieds/init.php on line 2 The first page you browse to is index.php: <? header('location: secured_page.php'); ?> Header refers it to secured_page.php: <? require('init.php'); ?> Then there is a bunch of HTML code under neath this page. This is the secured (password protected) page. The init.php that is required: <? session_start(); require('config.php'); require('quotes.php'); With more PHP code under neath. The first 7 lines of the login.php page are all HTML code. The 7th line in this page that is PHP is: : sha1(sha1($_REQUEST['password']).$_SESSION['salt']); I cannot for the life of me figure out why this is happening. Checked for whitespace and characters before the session_start() in the init.php file.

Hi guys, (I'm not sure if this is in the right topic. If not please could you move to the correct topic thanks.) Ok I recently moved my website from the host ULMB to a new host called Awardspace. My web site is a PHP code MMORPG which uses a MYSQL database. Whilst moving the website I did not change any of the PHP code. On the new host the PHP code still does work as it was programmed to do but these errors keep occurring on all the pages which contain PHP code to update the MYSQL database: Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /~/www/europeanwarfare.atwebpages.com/checklogin.php:1) in /srv/disk4/657046/www/europeanwarfare.atwebpages.com/connection2.php on line 2 Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /~/www/europeanwarfare.atwebpages.com/Shop/R3.php:1) in /~/www/europeanwarfare.atwebpages.com/Shop/R3.php on line 32 Warning: mysql_query() [function.mysql-query]: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) in /~/www/europeanwarfare.atwebpages.com/Shop/R3.php on line 124 Warning: mysql_query() [function.mysql-query]: A link to the server could not be established in /~/www/europeanwarfare.atwebpages.com/Shop/R3.php on line 124 Warning: mysql_select_db(): 2 is not a valid MySQL-Link resource in /~/www/europeanwarfare.atwebpages.com/Shop/R3.php on line 126 Warning: mysql_query() [function.mysql-query]: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) in /~/www/europeanwarfare.atwebpages.com/Shop/R3.php on line 127 Warning: mysql_query() [function.mysql-query]: A link to the server could not be established in /~/www/europeanwarfare.atwebpages.com/Shop/R3.php on line 127 Warning: mysql_close(): 2 is not a valid MySQL-Link resource in /~/www/europeanwarfare.atwebpages.com/Shop/R3.php on line 128 Warning: mysql_select_db(): 2 is not a valid MySQL-Link resource in /~/www/europeanwarfare.atwebpages.com/Shop/R3.php on line 129 Warning: mysql_query() [function.mysql-query]: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) in /~/www/europeanwarfare.atwebpages.com/Shop/R3.php on line 130 Warning: mysql_query() [function.mysql-query]: A link to the server could not be established in /~/www/europeanwarfare.atwebpages.com/Shop/R3.php on line 130 Warning: mysql_close(): 2 is not a valid MySQL-Link resource in /~/www/europeanwarfare.atwebpages.com/Shop/R3.php on line 131 Warning: mysql_select_db(): 2 is not a valid MySQL-Link resource in /~/www/europeanwarfare.atwebpages.com/Shop/R3.php on line 132 Warning: mysql_query() [function.mysql-query]: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) in /~/www/europeanwarfare.atwebpages.com/Shop/R3.php on line 133 Warning: mysql_query() [function.mysql-query]: A link to the server could not be established in /~/www/europeanwarfare.atwebpages.com/Shop/R3.php on line 133 Warning: mysql_close(): 2 is not a valid MySQL-Link resource in /~/www/europeanwarfare.atwebpages.com/Shop/R3.php on line 134 I just don't understand why I keep getting these errors? The PHP code still works fine and does update and retrieve information from the MYSQL data base correctly but these error keep occurring I just don't understand it? I spock to Awardspace and found that they run PHP v5.2.5 and MYSQL v5.1 and my old host ULMB ran on PHP v5.3.3 and MYSQL v5.0.90. I don't know if this is what is causing the problem? Feel free to see the errors for your self go to the web site at http://europeanwarfare.atwebpages.com/ and use the user name: tester and password: tester to login and see the errors. Then go to any page which contains PHP update code and these will be a error but the code will still work correctly? Thanks For Any Help! Fraser Hi I have an addon Domain, so you can open the site like http://www.mydomain.com/folder/ or http://www.otherdomain.com Now I want that when you are logged in you will be logged in in both, they have both the same folder. The loggin process works with $_SESSION, is there a way that the session_start() and the session_destroy can handle both sites? This topic has been moved to Third Party PHP Scripts. http://www.phpfreaks.com/forums/index.php?topic=351208.0 Hi, I was just wondering about the necessity of using cookies and session_start() to preserve state and provide personalization. Why can't it be done this way: The user logs in, the script adds the IP address of the client, together with his account info (say user id), and browser name, to a MySQL table, and configures the table (by setting a MySQL event) to delete that row after, say, 30 days (if not the user logs out in between, in which case the row is explicitly deleted). Now each time a page request comes from that client through that browser(as verified by grabbing the IP address and browser info), a check in the session table is done to see whether that IP address is in that table. If yes, it means that a user is logged in, and after grabbing the user id (necessary, because many users can log in from the same IP, whether from one or more than one browser), an accordingly personalized page is sent to the client. If no, then it sends just a normal page. Is it feasible or possible? Im trying to create two chained select fields using a guide I found online. The page loads fine my error does not occur until I select the first option in the preloaded select box. When I do that I get the following error: Quote Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /Applications/XAMPP/xamppfiles/htdocs/include/session.php:480) in /Applications/XAMPP/xamppfiles/htdocs/include/session.php on line 46 I have never had this kind of issue before so Im clueless as to why its happening.

Steve :-) I have an include file that is included in every page of my website. I'm using sessions and trying to streamline code. The very first line of any page is my include file, and the very first thing in that file is: Code: [Select] <?php session_start(); ?> The page doesn't register that a session was started. Do I have to have session_start() on every single page? Or is there a way to have it in my include file so it is automatically on every page for me? Thank you! I'm looking to connect to a MySQL localhost on my mac. I've been working for a few hours at this and I still can't figure it out. Below is my code.

Thanks in advance. <?php $first=$_POST['first']; $last=$_POST['last']; if (!$first || !$last) { echo 'Error: Enter the required data.'; exit; } if (!get_magic_quotes_gpc()) { $first = addslashes($first); $last = addslashes($last); } $hostname = 'localhost:8889'; $username = 'root'; $password = 'root'; $dbname = 'phonebook'; @ $db = new mysqli($hostname,$username.$password,$dbname); if (mysqli_connect_errno()) { echo 'Errer: Could not connect to database'; exit; } echo '.....Connected Successfuly'; $query = "insert into contact values ('null','".$first."','".$last."')"; $result = $db->query($query); if ($result) { echo $db->affected_rows." contact inserted into the database"; echo 'Contact Entered: '.$first.' '.$last.''; } else { echo 'Error: Contact not added.'; exit; } $db->close(); ?> Hi, my school say not to use XAMPP, and I already have PHP installed, MySQL installed, Apache I am not sure, but assuming if I have it installed, how do I connect to localhost b/c beforer when I use XAMPP, the default for where to get php/mysql running was: C:\xampp\htdocs\ Please any help appreciated! does anyone know of a simple tutorial which will show me how to receive email sent via my localhost? i cant develop my script fully because of the email errors. thanks |
