使用php和jquery根据访客/用户入口启用/禁用div

Question

I want to enable or disable a div according to the session if it starts with an user or a guest. I want to do something like this:

First, i will evaluate if it is user or not by doing this:

<?php

    if(!isset($_SESSION['idUser'])) // If it is Guest doesn't have id.
    {
        $guest=true;
    } else {
        $guest=false;
    }

?>

then in jquery, i would like to say:

$('.box').click(function(){    // labBox appears when box is clicked
    if(<?php $guest?>)                  
    $("#LabBox").hide();
    else
    $("#LabBox").show();                            

});

Question: how can i use my php boolean var $guest to disable or hide some elements of my website? Do i have to do two distinct php files? one for users and other for guest (e.g, home.php and home_guest.php)?

Answer 1

you could do the alternative such as

<script>
    var guest = '<?php echo $guest; ?>';
    $('.box').click(function(){    // labBox appears when box is clicked
        if(guest === "true") {             
            $("#LabBox").hide();
        } else {
            $("#LabBox").show();                            
        }
    });
</script>

This would simply allow you to pass the PHP value to a Javascript variable, in order for you to use it within the onClick.
