cancel and redirect page on editor.on('preSubmit'

itram

If user tries to submit a modification and session timeout has happened, I need to cancel submit but at the same time redirect him to the login page.
So to cancel submit I understand that the event has to return false:
editor.on( 'preSubmit', function ( e, data, action ) {
if ( abortSubmit ) {
return false;
}
} );
If the above is correct, where to add the:
header("Location: loginPage.php");
to redirect to the login page in this case?

Thanks

I would simply use a timeout to make sure "false" gets returned from the event handler. I would also avoid using client side PHP ( header("Location: loginPage.php"); ).

editor.on( 'preSubmit', function ( e, data, action ) {
    if ( abortSubmit ) {
        setTimeout(function(){
            window.location.href = "loginPage.php";
        }, 30)
        return false;
    }
} );
