PHP - Session Start Error
Similar TutorialsI am having trouble resolving an error. Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/s519970/public_html/header.php:27) in /home/s519970/public_html/admin/login.php on line 2 What I can gather is I can't use "header (Location: 'admin.php')" after i've used session_start(). I have tried to replace the header (Location: 'admin.php') with this: echo "<script>document.location.href='admin.php'</script>"; echo "<script>'Content-type: application/octet-stream'</script>"; I've been trying to read up on solutions but haven't been able to get it sorted. If anyone can offer some advice that would be greatly appreciated as im new to php. Code: [Select] <?php session_start(); if(isset($_SESSION['user'])) echo "<script>document.location.href='admin.php'</script>"; echo "<script>'Content-type: application/octet-stream'</script>"; ?> <div id="loginform"> <form action="dologin.php" method="post"> <table> <tr> <td><span>Username:</span></td> <td><input type="text" name="username" /></td> </tr> <tr> <td><span>Password:</span></td> <td><input type="password" name="password" /></td> </tr> <tr> <td colspan="2" align="right"><input type="submit" name="login" value="Login" /></td> </tr> </table> </form> </div> I have tried using require_once('yourpage.php'); before my <head></head> tags in the header document where I've specified the html information but this doesn't seem to work. I've been advised to use ob_start("ob_gzhandler"); but I am not sure how to implement this. Any advice is greatly appreciated! in this page http://maximaart.com/newscp/ i have this problem Code: [Select] Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/maximasy/public_html/newscp/index.php:1) in /home/maximasy/public_html/newscp/index.php on line 2 my source code is <?php session_start(); include_once("config.php"); include_once("functions.php"); $errorMessage = ''; if (isset($_POST['txtUserId']) && isset($_POST['txtPassword'])) { if ($_POST['txtUserId'] === "$user" && $_POST['txtPassword'] === "$pass") { // the user id and password match, $_SESSION['basic_is_logged_in'] = true; require("main.php"); exit;?> I am trying to create an index page which contains registration and login field the problem that i get is on successful login a warning is displayed session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at C:\xampp\htdocs\Eventz.com\index.php:116) in C:\xampp\htdocs\Eventz.com\index.php on line 235 This is the login part of my index.php this tag is inside an html table below the login form I also have a registration form and its php code above the login form Code: [Select] <?php if (isset($_REQUEST['pass'])) { $id=$_POST['id']; $pass=$_POST['pass']; $conn =mysql_connect("localhost","root",""); if (!$conn) { die('Could not connect: ' . mysql_error()); } /* checking connection....success! */ $e=mysql_select_db('test', $conn); if(!$e) { die(''.mysql_error()); } else { echo 'database selected successfully'; } if (isset($_REQUEST['id']) || (isset($_REQUEST['pass']))) { if($_REQUEST['id'] == "" || $_REQUEST['pass']=="") { echo "login fields cannot be empty"; } else { $sql=mysql_query("Select email,password from login where email='$id' AND password='$pass'"); $count=mysql_num_rows($sql); if($count==1) /* $count checks if username and password are in same row */ { session_start(); $_SESSION['id']=$id; echo "</br>Login Successful</br>"; } else { echo "</br>invalid</br>"; echo "please try to login again</br>"; } } } } ?> Any help or suggestion would be appreciated I have issues with a user being logged in and staying logged in, When logging in I create these $_SESSION variables
Array
(
[usr_login] => username
[usr_fname] => first
[usr_lname] => last
[usr_email] => email
[ses_usrid] => 1
[loggdin] => Yes
[loginremember] =>
)
And after login it looks great till I refresh the page or go anywhere else on the site. All variables above are gone. Consequently, this works with no issues on the prod server, just not on my machine. Code I've been playing with since it started, specifically the setting of the cookie. (this code runs before anything else)

Any ideas? Edited May 19, 2019 by KillGorackHi all, I have a session problem on my development site. Whenever I go to my login screen at www.mydomain.com/my/path/index.php, i get the following error messages: Quote Warning: session_start() [function.session-start]: open(/tmp/sess_f89c3850adf5a752b13f5c6b9022d8c4, O_RDWR) failed: Permission denied (13) in /home/account/public_html/shop_lite/admin/index.php on line 2 Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/account/public_html/shop_lite/admin/index.php:2) in /home/account/public_html/shop_lite/admin/index.php on line 2 However, when I go to mydomain.com/my/path/index.php, the error messages aren't there. I am very confused. We don't have an SSL (which google suggested it could be) or any whitespace between the opening php tag. I have chmoded the /tmp directory to 777 but to no avail. Any ideas? My opening code is below: Code: [Select] <?php session_start(); require_once("includes/db_connector.php"); include("includes/cms_class.php"); include("includes/login_class.php"); loginForwarder(); $issue = checkLoginIssue(); if (isset($_POST["login"])) { loginUser($_POST["email"], $_POST["password"]); } ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"><!-- InstanceBegin template="/Templates/my_template.dwt.php" codeOutsideHTMLIsLocked="false" --> hey guys, Im trying to register a session from a login im making and for some reason its not working. here is my code: <?php session_start(); if(isset($_POST['username'])){ $username = $_POST['username']; //name of the text field for usernames $password = $_POST['password']; //likewise here just for the password //connect to the db $user = 'root'; $pswd = ''; $db = 'chat'; $conn = mysql_connect('localhost', $user, $pswd); mysql_select_db($db, $conn); //run the query to search for the username and password the match $query = "SELECT * FROM users WHERE username = '$username' AND password ='$password'"; $result = mysql_query($query) or die("Unable to verify user because : " . mysql_error()); //this is where the actual verification happens if(mysql_num_rows($result) == 1){ //the username and password match //so e set the session to true $_SESSION['username'] = $username; $_SESSION['uID'] = $result['user_id']; //$_SESSION['email'] = $result['email']; //and then move them to the index page or the page to which they need to go header('Location: index.php'); }else{ $err = 'Incorrect username / password.' ; } //then just above your login form or where ever you want the error to be displayed you just put in echo $err; } else ?> Im trying to make it so it also gets the user_id of the user logging in and creates a session for it. It works for the username part, and Im able to echo the username im logged in with, but for some reason it does want to work for the user_id part. This is what doesnt register $_SESSION['uID'] = $result['user_id']; Thanks for the upcoming help.
I'm trying to start a session in a simple php file.
Here's *all* the code:
Here's the URL: I keep having the same problem when i run my script on the server. the error is Code: [Select] Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/alliapop/public_html/ekloges2010/ekloges2010/eisagogi.php:1) in /home/alliapop/public_html/ekloges2010/ekloges2010/includes/session.php on line 1I know i have to put session start at he very first line and i did but the problem keeps showing up. What else should i check? I have several pages on my site using the exact same code at the very top, which works fine except for one page: <?php include_once("../members/dbinfo.php"); The top of dbinfo looks like this: <?php session_start(); And then the connection strings for the database However it is giving me this error on this one page: Quote Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at C:\Inetpub\WebSites\premierathome_com\products\FrenchTalkingDictionary.php:1) in C:\Inetpub\WebSites\premierathome_com\members\dbinfo.php on line 1 Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at C:\Inetpub\WebSites\premierathome_com\products\FrenchTalkingDictionary.php:1) in C:\Inetpub\WebSites\premierathome_com\members\dbinfo.php on line 1 Now the session does actually start and doesn't prevent anything from working, I just get those messages. I'm at a loss as to why a different page with the exact same code, save for searching the database for a different product version would have this problem. I have had this code in place as well which works fine on other pages but doesn't help my problem at all: if(!isset($_SESSION['OK'])){ session_start(); } OK being a variable I set up during log in. I'm at a loss, is anyone able to help me out with this? Hi Everyone I am having a few issues with my website. I have developed in on my xampp local host and it works ok but when I upload the files and try to renew a membership using stripe I get the following messages. Warning: session_start(): Cannot start session when headers already sent in /customers/a/d/f/mywebsite.co.uk/httpd.www/mywebsite/inc/settings.php on line 2 Warning: Cannot modify header information - headers already sent by (output started at /customers/a/d/f/mywebsite.co.uk/httpd.www/mywebsite/procedures/payments/charge.php:1) in /customers/a/d/f/mywebsite.co.uk/httpd.www/mywebsite/procedures/payments/charge.php on line 141 I have some includes that appear on every page. This is the bootstrap.php file. This file holds the settings.php which connects to my database and other function files. In this settings page I call the session_start() php function and then connect to my database. I call the bootstrap.php file on every page to there for call the session_start() on every page. I am using sessions alot so is this the right thing to do? I have attached the renew_membership payment page which holds the form. The user fills out the payment page and the form data gets sent to a script called charge.php which uses the stripe objects to make the payment. I then want to do a redirect to the paymentSuccess.php page to output to the user that the payment was made successfully. This is where the issues arrise. I have split the charge file into 3 screen shots so it is more readable. Hope someone can help me. Thanks a lot David
Edited April 26 by Irish_Dave It is my understanding that <?php session_start (); ?> must go on the very first line otherwise "it won't work." But mine still isn't working, and I'm not sure why. These errors were returned EVEN AFTER I deleted everything in index.php except <? session_start (); ?>.... Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /home/xxx/public_html/xxx/xxx/index.php:1) in /home/xxx/public_html/xxx/xxx/index.php on line 1 Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/xxx/public_html/xxx/xxx/index.php:1) in /home/xxx/public_html/xxx/xxx/index.php on line 1 hey, i have this code: Code: [Select] <?php //-------------------------------- // Starting our session //-------------------------------- session_start(); //-------------------------------- // load database connection //-------------------------------- require "connect.php"; //-------------------------------- // Make some checks if the admin // Are loged in //-------------------------------- if ( ! isset($_SESSION['admin']) || ! isset($_SESSION['name']) ) { require "login.php"; die(); } if ( $_SESSION['admin'] != 1 || $_SESSION['name'] == "" ) { require "login.php"; die(); } if ( $core->input['act'] == logout ) { unset($_SESSION['admin']); unset($_SESSION['name']); session_destroy(); header('Location: index.php'); } ?> im trying to set a simple session, but i getting this error: Quote Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /home/rangreiss/domains/greissdesign.com/public_html/articles/admin.php:1) in /home/rangreiss/domains/greissdesign.com/public_html/articles/admin.php on line 7 Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/rangreiss/domains/greissdesign.com/public_html/articles/admin.php:1) in /home/rangreiss/domains/greissdesign.com/public_html/articles/admin.php on line 7 but as you can see i put the session start in the top of the file... any ideas? Thanks! hi all, I have a form that pass some $_POST values to a page that sets a session like this: session_start(); $_SESSION['TESTE'] = array ($_POST['sexo'],$_POST['nome'],$_POST['senha'],$_POST['senha2'],$_POST['login']); header ("Location: dddl.php"); Then the dddl.php should print the values on this line: print_r ($_SESSION['TESTE']) ; But when i run the application the dddl.php page returns this error: Notice: Undefined variable: _SESSION in C:\Users\Danilo\wamp\www\CNTur\dddl.php on line 2 Why it's not setting or why can't I reach the values? When I run the following code on the same page the session values are returned correctly: session_start(); $_SESSION['TESTE'] = array ($_POST['sexo'],$_POST['nome'],$_POST['senha'],$_POST['senha2'],$_POST['login']); print_r ($_SESSION['TESTE']) ; Thankx Danilo Jr. Hi, i've got a strange problem: i get this errors: Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at e:\Internet\pmtopagents\test.php:1) in e:\Internet\pmtopagents\test.php on line 3 Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at e:\Internet\pmtopagents\test.php:1) in e:\Internet\pmtopagents\test.php on line 3 but in my test.php is nothing else than: <?php session_start(); ?> there is no space in front of <?php where could be the error? best SO I have been developing a log in system and wanted to make my own simple CAPTCHA. I found one on the internet and ported the code across to get started and see how someone had made it. The issue I am having is that the dynamically generated image that I have created it seems is one step ahead of the session variable (the string is generated and then saved into session - then generates the image). But when i echo back the session it is always one step behind the actual image... Anyway here is my code and ask away please

Hi, I have this script which does what it is meant to do. I have assigned session_id() to the variable $sid so I can use it when logging in to a users account, however I get this error. How do I get around this? Warning: Unknown: Your script possibly relies on a session side-effect which existed until PHP 4.2.3. Please be advised that the session extension does not consider global variables as a source of data, unless register_globals is enabled. You can disable this functionality and this warning by setting session.bug_compat_42 or session.bug_compat_warn to off, respectively. in Unknown on line 0 As this is going to be installed on many servers, I do not want to have to edit the php.ini file on each one so as not to get this error. Is there an alternative way to assign the session_id() as so $sid = session_id(); so this doesnt happen? Code: [Select] <div id="pageNav"> <div id="sectionLinks"> <a href="admin.php?cmd=manage1&username=admin">Manage</a> <a href="admin.php?cmd=dashboard&username=admin">Dashboard</a> <a href="admin.php?cmd=msgcenter&username=admin">Message Center </a> <a href="admin.php?cmd=manage&username=logins">Logins</a> </div> </div> <div id="content"> <div class="page"> <table width="100%" border="1" align="center"> <td bgcolor="#99FF66"><div align="center"><span class="style3">Login</span></div></td> <td bgcolor="#99FF66"><div align="center"><span class="style3">Name</span></div></td> <td bgcolor="#99FF66"><div align="center"><span class="style3">Registration Date </span></div></td> <td bgcolor="#99FF66"><div align="center"><span class="style3">Approved </span></div></td> <td bgcolor="#99FF66"><div align="center"><span class="style3">Reset Password </span></div></td> <td bgcolor="#99FF66"><div align="center"><span class="style3">Delete</span></div></td> </tr> <?php session_start(); $sid = session_id(); session_register('sid'); include_once("data/mysql.php"); $mysqlPassword = (base64_decode($mysqlpword)); $db = mysql_connect("$localhost", "$mysqlusername", "$mysqlPassword") or die ("Error connecting to database"); mysql_select_db("$dbname", $db) or die ("An error occured when connecting to database"); $result = mysql_query("SELECT * FROM members"); while($row = mysql_fetch_assoc($result)){ echo "<tr><td><a href=templates/members/home.php?username=".$row['username']."&sid=$sid>".$row['username']."</a></td> <td>".$row['firstname']."
