Question

I am trying to create posts with a userid = to the currently logged in users id.
On page 1 I use $_SESSION to set a variable

$_SESSION['Userid'] = $row_getUserStuff['userid'];

I can call $_SESSION[‘Userid’] on both page 1 and page 2 with

echo($_SESSION['Userid']);

which outputs the users id, my problem is when I try to push that data to the database.
In the form I put

<input type="hidden" name="userid" value="<?php $_SESSION['Userid']?>" />

But when I try to post it I get the error

Column ‘userid’ cannot be null

try this:

<input type="hidden" name="userid" value="<?php echo $_SESSION['Userid']?>" />

You’re not actually telling PHP to output the session variable, you’re just referring to it. But since it’s a session variable, it doesn’t need to be in the form at all, I assume there’s a $_POST['userid'] somewhere in your code to handle the form, just replace that with $_SESSION['Userid'].
