Have 2 users it only recognises user 1.

[ragos200]

HI guys,

Created a matchmaking form with 2 users,user 1 fills it out saves the information then user 2 fills it out and the result is calculated.

Problem is that user 1 fills it out and it won't recognize user 2 so I can't calculate anything.

I have tried many times to fix this but it dosn't work,

Please help me by telling me what's wrong with my code.

<?php
session_start();
$difference=0;
$match=0;
$nmatch=1;
$result=1;


if(isset($_POST['check']))
{

    if (!isset($_SESSION['userOneName']))
    {
        $_SESSION['userOneName'] = $_POST["username"];
        $_SESSION['userOneBirthYear'] = $_POST["birthyear"];
        $_SESSION['userOneGoal'] = $_POST["goal"];
        $_SESSION['userOneFavorite'] = $_POST["favorite"];
        $_SESSION['userOneCat'] = $_POST["cat"];
        $_SESSION['userOneDog'] = $_POST["dog"];   
        $_SESSION['userOneHamster'] = $_POST["hamster"];
        $_SESSION['userOneGoldfish'] = $_POST["goldfish"];
        $_SESSION['userOneHuman'] = $_POST["human"];
        // create ALL session variables for user1 according to what's in the input vars: $_SESSION["userOneSomething"]=$_POST["something"];
    }
    else

Look at your code that processes the form. When the first user submits the form, the code sets up the userOne* values. Then what? What will the code do next? I don't mean what it should do, I mean what does it actually do? Try to step through the code in your head as if you were executing it to see what happens.

Try something like this to organise your users:

session_start();
$_SESSION['users'] = [];

function addUser($data) {
    $_SESSION['users'][] = [
        'name' => $data['username'],
        'birthYear' => $data['birthyear']
        // ...
    ];
}

if (isset($_POST['check'])) {
    addUser($_POST);
    
    $numberOfUsers = count($_SESSION['users'])
    if ($numberOfUsers == 1) {
        // do user 1 stuff
        // $user1 = $_SESSION['users'][0];
    } elseif($numberOfUsers == 2) {
        // do user 2 stuff
        // $user1 = $_SESSION['users'][0];
        // $user2 = $_SESSION['users'][1];
    }

}
