Question

I want to save a cookie for a visitor. I use the code below but it seems it won’t work for me. Please guide me where I am wrong

<script type="text/javascript">
    if(!isset($_COOKIE['visited_alreadyxxx']))
    {
        setcookie('visited_alreadyxxx' , 'true' , time()+60*60*24*7*365);  
        alert("hi");
    }
</script>

demo

Edit : sorry for above code , does below code work correctly ?

<?php 
    if(!isset($_COOKIE['visited_alreadyxxx']))
        {
            setcookie('visited_alreadyxxx' , 'true' , time()+60*60*24*7*365);  
          ?>

<script>alert("hi");</script>
<?
        }

Answer 1

I don’t think you can access cookies like that. It appears to be PHP, mixed with Javascript.

1. isset() is a PHP function
2. $_COOKIE is how you access cookies in PHP
3. setcookie is also PHP
4. alert is Javascript.

The Javascript interpreter doesn’t know how to parse PHP, and will fail to execute.
