Question

What I’m doing is, if I haven’t got an ID in either $_POST or $_SESSION then redirecting. Preference is given to $_POST. So I have this:

$bool = 0;
if (isset($_POST['id'])) {
    $bool = 1;
} elseif (isset($_SESSION['id'])) {
    $bool = 1;
}
if (!$bool) {
    ...//redirect
}

Is there a quicker way to write this, APART from just removing the braces?

You could just do:

$has_id = isset($_POST['id']) || isset($_SESSION['id']);

if (!$has_id) {
    // redirect
}

(I’d recommend you to give your variables more descriptive names than just $bool.)

Although if you aren’t using the variable for anything else, you could just do:

if (!isset($_POST['id']) && !isset($_SESSION['id'])) {
    // redirect
}
