You have to call session_start first in the second page to access the session variable.

There are similar questions related to the topic but none of them have solved my problem. Its kind of weird but my $_SESSION is working on the same page but not on any other page. If I put isset($_POST['submit') the condition doesn't satisfy and without it the $_SESSION remains null.
This is my code.
This is the login page.
<!-- Login.php -->
<?php
session_start();
?>
<html>
<body>
<form method="post" action="profile.php">
<fieldset>
<legend>
Login
</legend>
<label> User ID :</label> <input type="text" placeholder="Username" name="user"><br>
<label> Password :</label> <input type="password" placeholder="Password" name="password">
<input type="submit" name="submit" value="Login">
</fieldset>
</form>
</body>
</html>
<?php
if(isset($_POST['submit'])){
$_SESSION['USER']= $_POST['user'];
$_SESSION['PASS']=$_POST['password'];
}
?>
This is where I want my session variable to appear.
<!-- profile.php -->
<?php
session_start();
echo "Session user is ".$_SESSION['USER']."<br>";
unset($_SESSION['USER']);
unset($_SESSION['PASS']);
session_unset();
session_destroy();
?>
This is what I have tried :
Changing form method to GET.
Using $_REQUEST and $_GET.
Using $_SESSION on the same page. It works on the same page.
Checking session id. The session on the other pages are present but values are either null or empty.
Running the code without isset(). In that case all the session variables remain NULL.
$_POST['submit'] and the rest of the post parameters are not available in Login.php
They are available only in profile.php because your form action points to it.
You may move the following code after the session_start() in profile.php.
if(isset($_POST['submit'])){
$_SESSION['USER']= $_POST['user'];
$_SESSION['PASS']=$_POST['password'];
}
Keep in mind that you unset the session values in the end of profile.php
I'm a student and I'm making a quiz using php and mysql, my problem is I'm trying to echo a name on the results page but it doesn't work.
My first page is an index page where I create a form which gets the users name which I send to my quiz.php page.
<form method="post" action="quiz.php">
<img src="pictures/indeximage.jpg" alt="horrormovies" width="1024" height="640">
<p>
Please Enter Your Name
<br>
<input type="text" name="name">
</p>
<input type="submit" name="submit" value="Start">
</form>
on my quiz.php page i put make a variable and put it in a session
<?php
//start session
session_start();
$var_name=$_REQUEST['name'];
$_SESSION['ses_name']=$var_name;
?>
On my results page I have this
<?php
session_start();
$var_name=$_SESSION['ses_name'];
?>
<p>
Thank you for taking the quiz <?php echo $var_name; ?>.
</p>
Use isset for assign value in session variable. for good practice.
if(isset($_POST['submit']))
{
//start session
session_start();
$var_name=$_REQUEST['name'];
$_SESSION['ses_name']=$var_name;
}
quiz.php
session_start();
if($_SERVER['REQUEST_METHOD'] == 'POST')
{
$_SESSION['ses_name']=$_REQUEST['name'];
}
Try this code :-
results page
<?php
//start session
session_start();
if(!empty($_SESSION['ses_name']))
{
?>
<p>Thank you for taking the quiz <?php echo $_SESSION['ses_name']; ?>.</p>
<?php
}
else{
echo 'session not set ';die;
}

I am setting a session variable when a submit button is pressed like so:
<?php
$submit = #$_POST["submit"];
if($submit){
$_SESSION['id'] = $id;
}
?>
<form action="add.php" method="POST">
<input type="submit" name="submit" value="Add">
</form>
However, in the page add.php when I do:
print_r($_SESSION['id'];
I get the following error:
Undefined index: id
I'm new to sessions so still trying to come to grips with them, but I thought the part where I do $_SESSION['id'] = $id; is where I define the index id to be the value of the $id variable? Could someone explain where I am going wrong?
UPDATE:
In case you're wondering if I am using session_start(): At the top of the page with the form, I include my header page which at the top contains require_once './init.php';. At the top of my add.php I just have the line require_once './init.php'; (I do not include the header file in add.php as this page will redirect as soon as it has executed its code.
In the init.php file is the following:
<?php
session_start();
require_once 'configurate.php'; //database info
?>
you should call session_start() before setting any values in $_SESSION
change your code like this
<?php
session_start();
$submit = #$_POST["submit"];
if($submit){
$_SESSION['id'] = $id;
}
?>
<form action="add.php" method="POST">
<input type="submit" name="submit" value="Add">
</form>
I hope you have initialized your session via session_start before setting and retrieving the value from $_SESSION
if the value submitted via $_POST["submit"] compares to false (e.g. "" or 0) your condition if($submit) won't succeed, better use if (isset($_POST['submit'] instead
I have numerous pages that I need to access a variable on. This variable is assigned a value when a user enters an ID into a form on accounts.php:
account.php
<form action="afterlog.php" class="form" method="post">
<input type="text" name="amid" id = "amid" class="input" />
<input class="btn" type="submit" value="Go" />
</form>
which posts the value 'amid' to afterlog.php
afterlog.php
<?php
session_start();
if($_SERVER['REQUEST_METHOD']=='POST')
{
$_SESSION['account_manager_id']=$account_manager_id;
$account_manager_id = $_POST['amid'];
header('Location: customer_view.php');
}
?>
which checks the POST, assigns the session variable, and redirects rhe user to customer_view.php
customer_view.php
I need to use '$account_manager_id' in this page and all pages after. Here is how I am assigning it the value of the _SESSION variable:
<?php
session_start();
$_SESSION['account_manager_id']=$account_manager_id;
?>
Bu the value isn't being held on any of the pages, including customer_view.php. I know its passing to afterload.php because it prints out on that page, but its gone after that page.
What I am doing wrong?
Thanks for your help!
You are trying to assign a value to $_SESSION['account_manager_id'] before $account_manager_id has any value in it. You just need to switch the order:
$_SESSION['account_manager_id']=$account_manager_id;
$account_manager_id = $_POST['amid'];
or simply:
$_SESSION['account_manager_id'] = $_POST['amid'];
in afterlog.php
<?php
if($_SERVER['REQUEST_METHOD']=='POST')
{
$account_manager_id = $_POST['amid'];
$_SESSION['account_manager_id']=$account_manager_id;
header('Location: customer_view.php');
}
?>
or
<?php
if($_SERVER['REQUEST_METHOD']=='POST')
{
$_SESSION['account_manager_id']=$_POST['amid'];
header('Location: customer_view.php');
}
?>
I have 2 php files in my folder. In page1.php, there's a textarea, user should enter some values in it. In page2.php, it will grab what is in the textarea and work with its program. But I can't find a command that grabs the value in textarea. Can someone help me?
page1.php:
<?
$hello = "hello";
?>
<html>
<input type = "text" name = "user_input">
</input>
</html>
page2.php
<?
ob_start();
include 'page1.php';
ob_end_clean();
echo $hello;
?>
So, is there anyone that can solve this? =/
Use $_GET or $_POST in page2.php
page1.php
<?
$hello = "hello";
?>
<html>
<form method="get" action="page2.php" enctype="multipart/form-data">
<input type = "text" name = "user_input">
<input type="submit">
</form>
</html>
page2.php
<?
$text=$_GET['user_input'];
ob_start();
include 'page1.php';
ob_end_clean();
echo $hello;
echo $text;
?>
You may use either $_GET['user_input'] or $_POST['user_input'].
The difference is, you can see the data in the url (visible to everyone) when using GET method and not in the other method.
Also, always use <input> elements (which you want to pass to another file) inside a <form> and specify action="file.php", to where you want to pass data, and the method, either method="get" or method="post", like;
<form method="get" action="page2.php">
also specify the method to grab data in the target file also, like;
$text=$_GET['user_input']; or $text=$_POST['user_input'];
And in your case, you may use;
Method 1
<?php
$hello = "hello";
?>
<html>
<form method="get" action="page2.php">
<input type="text" name="user_input">
<input type="submit">
</form>
</html>
page2.php
<?php
$text=$_GET['user_input'];
echo $text;
?>
Method 2
<?php
$hello = "hello";
?>
<html>
<form method="post" action="page2.php">
<input type="text" name="user_input">
<input type="submit">
</form>
</html>
page2.php
<?php
$text=$_POST['user_input'];
echo $text;
?>
If you want to share the data over a number of pages, you may do this using PHP Session or saving the data in a cookie.
1. Using Sessions
<?php
session_start();
$_SESSION['data'] = 1; // store session data
echo "Pageviews = ". $_SESSION['data']; //retrieve data
?>
Make sure you add session_start(); on every page you want to handle session
You can read more about php sessions here www.tizag.com/phpT/phpsessions.php/
2. Using Cookie
<?php
setcookie("user", "Alex Porter", time()+3600);
?>
and retreive it using
echo $_COOKIE["user"];
You can read more about php sessions here http://www.w3schools.com/php/php_cookies.asp
hope this helps...:)
basically your page1.php is a page with some form in it with a text area. Now user will have to fill it and submit the form to page2.php. You can't echo it's content like that, because that will be on browser subject to user actions. Use a form and submit the data to page2.php. Like this:
page1.php
<html>
<head>
</head>
<body>
<form action="page2.php" method="post">
<textarea name="t1">
</textarea>
</form>
</body>
</html>
page2.php
<?php
$textAreaContents = isset($_POST['t1'])?$_POST['t1']:'';
echo "You submitted: ".$textAreaContents;
?>
if i were you i should use sessions for this. that is where they were made for..
example:when user clicks on submit.
<?php
if($_SERVER['REQUEST_METHOD'] == 'POST')
{
$_SESSION['post'] = $_POST;
}
that is where every post variable will be put in a session.
and your inputbox will be something like this..
<textarea name="message" type="text" value="" rows="0" cols="0" placeholder="" ><?php if(isset($_SESSION['post'])){echo $_SESSION['post']['message'];} ?></textarea>
?>
note that you now can use every post variable that you used in your form by echo (example)
echo $_SESSION['post']['message']
where message is the name of the inputbox. in this case of the textarea
don't forget that at the end when you don't want to use the session anymore use session_destroy(); otherwise you will keep having it in your form. and don't forget session_start(); above every page where you are planning to use sessions ( it must be at 1st line of your document at all times)
