$_SESSION throughout entire domain.

[ConnorMcF]

What I'm trying to do is get my $_SESSION to work throughout my website.

I'm quite new to PHP, so the PHP Manual didn't make much sense to me, so I thought I'd post here! ^^

 

I've got my login script under /session/ and I want it to be able to display your username on the homepage (/), but it only works inside /session/.

 

If you are wondering, I am using PHP-Login Advanced.

 

Thank you,

- Connor!

session_start() needs to be at the very top of all of your pages, or else the session data won't be available to that page/script.

Yeah like CroNiX said if you do not have session_start() and you try to use $_SESSION your going to get an error, and have you tried making a functions.php file and adding session expressions into it? because then you can just include the functions.php file into all the other .php files.

 

Also if you want to display the username do the following i'll add security in this example:

<?php

//Get values sent from form
$username = $_POST['username'];
$password = $_POST['password'];

//Strip tags from string
$username = strip_tags($username);
$password = strip_tags($password);

//Encrypt password
$password = hash('fnv164', $password);

//Escape from HTML
$username = mysqli_real_escape_string($username);
$password = mysqli_real_escape_string($password);

//Convert special characters
$username = htmlspecialchars($username, ENT_QUOTES);
$password = htmlspecialchars($password, ENT_QUOTES);

//If you are on another page and you want to echo the username
session_start(); //Critical this MUST be at the top of the page.

//Check if SESSION is set
if(isset($_SESSION[''])) {

$_SESSION['username'] = $username;

}

echo "Welcome, ".$username."!";

?>

Not sure if i went to over the top there but hopefully it should help you out

Likely, the cookie associated with your cookie is only available to /session/ and other children directories.  Try using something like session_set_cookie_path() or session_save_path().

[CroNiX]

There's nothing in that script that changes the location of session cookies or save paths. Most likely the OP just isn't using $_SESSION properly on his new custom pages outside of that login script.

[NotionCommotion]

I didn't look at the script, but he did say it works under /session/ but not the homepage (/).

[CroNiX]

Yeah, that's where he installed the login library. So it works there, but now the OP wants to use the sessions generated by logging in on OTHER pages.

[Werezwolf]

As all previous posters above have stated make sure that you start your session

<?php
if(!session_id()){session_start();}
?>

 

EDIT: Actually you might not of installed PHP-Login Advanced correctly. As i have not used it myself of the installation options, you may want to try reinstalling that before you move on to my next suggestion. If there was anything about session cookies or directories you may want to keep them at default.

 

If that dose not work you php.ini may not be configured correctly i would edit that first or if you cant your Last option is.

 

<?php
session_set_cookie_params (0,'/','mywebsite.com',0,0);
if(!session_id()){session_start();}
?>

Dose anyone have a problem with $_SERVER['SERVER_NAME'] as a catch all ?

As it may be a better suggestion

session_set_cookie_params (0,'/',$_SERVER['SERVER_NAME'],0,0);
