I've been advised to use ob_start("ob_gzhandler"); but I am not sure how to implement this. Any advice is greatly appreciated!

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.

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

I'm trying to start a session in a simple php file.
Here's *all* the code:
Here's the URL: Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/hedgehog/public_html/class/class.phpmailer.php:3005) in /home/hedgehog/public_html/admin/class/authenticate.class.php on line 15 I own a website, www.gpstudios.com Some time ago I started recieiving this error after posting comments on the playgame page/news page. Try posting comments yourself on this game: http://www.gpstudios.com/playgame.php?gameid=324 I have attached a picture of the error. Unfortunately, I have no idea when this bug appeared. It must have happened a while ago, but I never noticed. Anyone know how or why I am getting this bug? Because I'm unsure as to where/when the error occurred, I cannot supply the code. Sorry for the lack of details, but I'm hoping someone will understand this error a little better than me :S Thanks, -Tom Hi, I am just recently getting this error message:Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /home/XXX/chordsandguitar.com/index.php:46) in /home/jchords/chordsandguitar.com/index.php on line 48 this is no doubt related to the fact that my site has been hacked along with 1000's of others that are on dreamhost. I don't know if it's related to php file permissions some of my files may have had had their permission set for read-write when they should not have been. They have all been changed to the more restrictive 755 or 644. So here is how I am using the session_start to store some variables: Code: [Select] session_start(); if (!isset($_SESSION["count"])) { $_SESSION["count"]=0; } else $_SESSION["count"]++; if ($_SESSION["count"] == 0) { $scale_menu = 'C'; $variation_menu = 'maj'; $code_id = '1'; } else { //allows retreiving the value of the drop-downs after the Select button has been pushed // has to be skipped on the first access or overwrites starting vars. to null if (isset($_GET['s_menu'])) $scale_menu = $_GET['s_menu']; else $scale_menu = $_GET['scale_menu']; } So any ideas why I am getting this error?

How do I redirect the header location on a session page. I thought I could go a different direction, but now I'm back to this one. I tried just adding header("Location: newpage.php") at the end of a query insert, but it gave me the warning that it can't modify the head. But I need the page to redirect after the query is done. Thoughts? Hi 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" --> 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 KillGorackhey 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 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? Hi All, I have a secure website which always checks the cookies is not expired and the session id is set. When someone doesn't browse for the period of the cookie it will expire however the session id stays valid until he logout. A lot of people don't logout so the pages will still be accessable for them or others who use their pc. Is there a way to destroy the session id when the cookies expires? Marco 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? hello all, I have a client that wants to protect their web page with a password protected landing page. Once the password is entered the user is directed to a "disclaimer" page that they have to agree to first before going into the site. I have put both the landing page and the disclaimer page in my root directory and then the site I put in a sub directory /cms/ in the main site index.php I check for the post password and then set a $_COOKIE for the user that will expire in 1 month <?php // this goes on the very top of the index.php file in the template you are using //check if user has entered password and needs cookie set if(isset($_POST['fpass']) && !isset($_COOKIE['fpass'])) setcookielive('fpass', $_POST['fpass'], strtotime( '+1 month' )); function setcookielive($name, $value='', $expire=0, $path='', $domain='', $secure=false, $httponly=false) { //set a cookie as usual, but ALSO add it to $_COOKIE so the current page load has access $_COOKIE[$name] = $value; return setcookie($name,$value,$expire,$path,$domain,$secure,$httponly); } The next thing I do is check if a user is trying to access the main site with having the COOKIE - if so I redirect the user to the landing page //check if user has not entered password if (!isset($_COOKIE['fpass']) || $_COOKIE['fpass'] == "") header('location: http://www.mypage.com'); This works fine up to this point. Now my problem is that I also need to check if a user has the month long cookie set but is trying to access the main page without viewing the disclaimer page first. I thought this would work: //check if the user has a cookie set but is on a new session if (isset($_COOKIE['fpass']) && !isset($_SESSION['fpass'])) header('location: http://www.mypage.com/disclaimer.php'); But this only throws the user into a loop of "disclaimer" -> "landing page" -> "disclaimer" etc. They can never get into the main site. How do I check for the cookie and whether the user has visited the disclaimer page - but then allow the user to continue once they go to the disclaimer page? NB: the $_SESSION is not set until the main site. The default PHP Session name on my webspace server is PHPSESSID. Does that mean that the session cookie will be called PHPSESSID? The reason i ask is that in a couple of places i can't use PHP to update the information in the session cookie (because PHP is parsed before the webpage loads) and so i need to use Javascript to update a cookie which i would prefer to be the session cookie used by PHP. I guess i'm asking what the name of the cookie is, how i would refer to it in Javascript (if that is even possible) so that i can update it and whether this would cause any issues with the info already stored in the session cookie by PHP. Cheers NM hey guys im using a session cookie to store a user_id, only if user has clicked to remember me on the login form...that way when autenticating it checks id in db and if matching a user it logs in automatically.
now the problem i want to just remove user_id from a session cookie. if i use the code below to delete the user_id session then it will remove all session cookies.
is there a way just to remove 1 session cookie? thank you
// create session cookie
session_start();
session_set_cookie_params('3600', 'C:\Users\Ricky\Desktop\www\BiSi\private\tmp\session', 'http://127.0.0.1/', true, true);
ini_set('session.gc_probability', 1);
session['user_id'] = 1;
//delete session cookies
setcookie (session_name(), null, time() - 3600);
session_regenerate_id(true);
any help/advise would be greatful...cheers guys
