Variable wont store in session

[thecactusjack]

Hello, new to php. having trouble storing one particular variable into the session.

Here is where I want to echo the result once the user has returned to the page:

<?php
if ($_POST['submit']) {
$show = $result;
$_SESSION['show'] = $show;
} 
else {
$show = $_SESSION['show'];
echo "The last result was: ". $show;
}
?>

 

//inbetween here a form is created

Here is where the $result variable is created:

<?php 
$decision = $_POST['option'][array_rand($_POST ['option'])];
if (!$decision){
$result = $_POST['default'];
echo $result;
}

else{
$result = $decision;
echo $result;
}
?>




Now the strange thing is if I change "$show = $result;"
to "$show = $_POST['default']; 
That does store and displays when the user returns t the page.

 

So everything else works apart from "$result" being stored. 

Any help would be great! spent hours going mad on this!

session_start() must be at least in the file. preferably the first line of each file.

Hi yeah I have :

 

 

<?php 

session_name('Session1');

session_set_cookie_params(6000);

session_start(); 

 

?>

 

All at the start of my code, still the "$result" variable does not store or display, however "$_POST['default']" does, any idea what the issue might be?

Thanks 

 

*Edit "$result" variable

Honestly your code and description doesn't make any sense.

 

Start debugging by echoing every variable when you need to use it and see what it is.

As the function name implies, you need session_start() before you use session variables

Yes I do have this at the very start.

Like I said if I store the "$_POST['default']" variable as opposed to the "$result" variable in the session, it stores and echos once the user returns to the page as I intended.

Don't PM members asking for help, that's what the forum is for. Obviously $result isn't set so figure out why.
