结合$ Session和$ Check

Question

In the header of the Home.html file, I use the $session function like this

<?php
@session_start();
if(  $_SESSION['flag']==1)
echo'<script>window.location="login.html";</script>';
?>

While in the code above it only directs the user to the login file if they has not login yet.

---

What I want now is if the user has not login yet then they are still able to acess the home.html file however there are some content that I want to hide to the unregistered user.

I use this code to generate this:

$(document).ready(function(){
$check=1;
$("span").click(function(){
    if($check==0)
    {
        $("#login").show();
        $("#logout").hide();
    }
    else
    {
        $("#logout").show();
        $("#login").hide();
    }
});
});

So my question now, What I need to change in the header of the html file (in the session function) so that it can be combined with the $Check function?"

Answer 1

You have to combine php and javascript a bit like in the following example:

$(document).ready(function(){
    var check = <?= $_SESSION['flag'] ?>;

    $("span").click(function(){
        if(check==0){
            $("#login").show();
            $("#logout").hide();
        } else {
            $("#logout").show();
            $("#login").hide();
        }
    });
});

The shown example awaits $_SESSION['flag'] as integer value. Is $_SESSION['flag'] a string you have to set the check var in quotes.
