PHP - Continue Sessions

i'm need to retrieve a session after i've collected the data and went to PayPal (...urk...)  i think i'm starting off correctly... but how the hell do i get the session name on the other side?

Code: [Select]
$uuid = uniqid();
session_name = $uuid;
session_start();

//  do some stuff

//  go to PayPal

//  come back from PayPal

....um... now i'm lost!  how do i get the $uuid here??

once i come back from PayPal... this is where i get lost.  how do i load a UUID-based session if i can't get the $uuid?   

and if there's a better way, by all means let me know!    someone said i could pass the $uuid through PayPal, but i'm not seeing how yet...   

TIA gang!

WR!

I am getting the following error when using composer: "continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"?

Just started.  I am pretty sure composer.json wasn't changed.  journalctl doesn't show anything.  Maybe Doctrine related, however, nothing seems to help.

Any ideas?

Hi

Something strange is happening and I can't understand it.

A user can access an availability page of accommodation and book ita room, this works fine, and goes from availability to the booking form and back quite well, carrying the room  id of the accommdation and room/s selected in a session.

If they close the browser down and open the availability page again all the rooms are there as before, but when they select a room and go to the booking form the session of the room  id  and the rooms selected are empty.

If I do a session destroy and open the browser up again everything works fine again.

I have tried this in Chrome and Firefox and it seems to work fine

Any help would be appreciated

When using sessions, must there be a session_start()
in each page for the browser to be considered part of the session?

Can a user browse to a page without session_start() and still have that part of the original session that he/she began with??

I am trying to create a blog and visitor log, where I should be able to log in as admin and add the item and see the visitor log.
I want a password protected administration section and I want to use sessions on the administration section.

When I for example click on add post, I want it to log in and go to page addpost.php where I can enter my text.

This is what I've done so far. I would like to know what I have done wrong and how I should do to accomplish what I have mentioned above.




<?php
session_start(); 
if(isset($_POST['btnLogin']) || isset($_POST['addpost'])){
$txtUserId = $_REQUEST['txtUserId'];

$txtPassword = $_REQUEST['txtPassword'];

if (isset($_POST['txtUserId']) && isset($_POST['txtPassword'])) {

if ($_POST['txtUserId'] === 'admin' && $_POST['txtPassword'] === 'abc123') {

//$_SESSION['basic_is_logged_in'] = true;

echo "you are logged in";

}

elseif (empty($txtUserId) || empty($txtPassword))

{
echo "fill in username and password";
}  
elseif ($_POST['txtUserId'] != 'admin'){

echo "wrong username";

}

elseif ($_POST['txtPassword'] != 'abc123'){
echo "wrong password";

}
}
}
?>
<?php
//if (!isset($_SESSION['basic_is_logged_in']) 
//   || $_SESSION['basic_is_logged_in'] !== true) 
  
?>

Hello,
Is there a problem in destroying a session and then starting it in the same file, for example:


session_name();
session_start();

session_destroy();



And lastly, if I create a variable $_SESSION['user'] under a session called 'one' i.e. session_name("one") and then create another variable $_SESSION['user'] under a session called 'two' i.e. session_name("two").
Are these two variables the same?

I there. I am making a small game, either you or the computer win depending on who's life hit 0 first I am using sessions to hold the health values, however I need a little bit of help. How do I make it actually go down after each move until one hits 0? Here is my script and thanks in advance...

session_start();

I have a simple php script that starts sessions. On every page, I include :

if(isset($_SESSION['sessionname'])){
//The rest of the page
}
else
{
die("Not logged in");

}
I always include the session start and always regenerate the session id after <?php. The code works fine withevery browser except for a certain version of Internet Explorer 8. Even though the browser does enable cookies, it doesn`t seem to allow the ones in my script. In fact, every time I change page, it ives the error message "Not logged in". I have tried it on two different compters with the exact same version of IE and the result was the same.

Thank you for your time!

Basically I am trying to make a login with sessions but its just not working. Can someone look and see for any errors in what I wrote or snippet suggestions?

I have an "Email a Friend" form that captures the referring url and saves it in a session.  The problem is that if someone decides not to send the form and navigates away from the page, and then decides to email another page, it saves the previous url.  How can I have it so that it clears the previous url and uses the new one?

Code: [Select]
if(!isset($_SESSION['referrer'])){
//get the referrer
if ($_SERVER['HTTP_REFERER']){
$referrer = $_SERVER['HTTP_REFERER'];
}
else{
$referrer = "http://www.mcse-training-classes.com";
}
//save it in a session
$_SESSION['referrer'] = $referrer;
}

Im makigna simple login system for a sight but i only want them to have to login if they want to go to the shopping cart i have t implement a session_start() on every page before the cart page so the home page products page etc etc and then on the cart page ive a simple function that checks if their logged in if not then it will direct them to the login page if they are they should just continue is this the correct way to do it ?

thanx

I got a log-in form with database, it only logs if such username and password exists. I was told that if i wanna make a log-out button once logged-in, i need to add sessions to my code and idk how..

this is my code that checks if username/password exists, and if so it lets u log in, if not it displays a msg:

if(isset($_POST['loginsubmit'])){
if($username !="" && $password !="") {


///////////////////////////////Check for username/pass in database////////////////////////////
$nameexists = false;
$passexists = false;
$result = pg_query("SELECT name FROM duom WHERE name='".$username."'");
while ($row = pg_fetch_array($result)) {
if($row['name'] != ""){
$nameexists = true;
}
} if($nameexists) {
$result = pg_query("SELECT pass FROM duom WHERE name='".$username."'");
while ($row = pg_fetch_array($result)) {
if($row['pass'] == $password){
$passexists = true;
echo "Prisijungimas pavyko, jusu vartotojo vardas - ".$username."";
include"loggedinform.php";
} else {
echo "Slaptazodis netinka!";
}
/////////////////Starts session if password is correct////////////////////////////////////////////
if ($passexists){
//Here i want it to start the session if password is correct
}
//////////////////////////////////////////////////////////////////////////////////////////////////////////
} 
} else {
echo "Tokio vartotojo nera!";
}
//////////////////////////////////////////////////////////////////////////////////////////////////////////


} else {
echo "Uzpildykite visus duomenys!";

if ($passexists){
session_start();
}

I am new to SESSIONS and have a quick question about them.

I want to use sesssions on my site but was wondering if they would work for the follow senario.

Say a customer visits my url: http://www.mysite.com/?id=2

Now what i am doing is taking the id out of the URL using sessions and redirecting the user to  http://www.mysite.com while my session ($_SESSION['id']) holds the value 2 in it. I have this working great, i believe it just looks better.

Now if my customer decides to buy my product via paypal and is directed off my site while he/she is paying for said item on paypal when they return could i still use some of the information that i stored in my session??

I know i could use post and get to pass through paypal but unfortunately i have to use sessions for what i am trying to do.
