PHP-HTML passing multiple selection value in to session variables

Question

I just start learn PHP, HTML thing, but got bumped in to select options and handling. here is my code:

<select id="VarRole" class="form-control">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</Select>

<select id="VarAcct" class="form-control">
<option value="1">A</option>
<option value="2">B</option>
<option value="3">C</option>
</Select>


if (isset($_POST['VarRole'] && $_POST['VarAcct'])) {
    $_SESSION['VarAcct'] = $_POST['VarAcct'];
    $_SESSION['VarRole'] = $_POST['VarRole'];
    echo '<script type="text/javascript"> location.href = "success.php"; </script>';
   }

My goal is to send 2 selected result to become session variables and if success it will redirect to success.php page.
Sorry if my explanation are not quite clear, feel free to ask

Form elements do NOT send the ID attribute when the form is submitted - it is the name that forms the key in the request array.

<select name="VarRole" class="form-control">
    <option value="1">1
    <option value="2">2
    <option value="3">3
</Select>

<select name="VarAcct" class="form-control">
    <option value="1">A
    <option value="2">B
    <option value="3">C
</Select>

isset will accept multiple items to verify at once ( returns false if any item fails the test ) but you separate with a comma - there is no need to use && within the arguments.

One other thing - it would be cleaner to use header to redirect rather than use Javascript as you were trying to do.

<?php
    if ( isset( 
        $_POST['VarRole'],
        $_POST['VarAcct']
    )) {
    
        $_SESSION['VarAcct'] = $_POST['VarAcct'];
        $_SESSION['VarRole'] = $_POST['VarRole'];
        
        ob_clean();
        exit( header('location: success.php'));
    }
?>
