如果特定用户，在PHP内部的JavaScript

Question

Im new to PHP, so maybe this is a stupid question. I have some code that should show a livechat for all Wordpress users, in access level 7, and show nothing to people who have another access level.

  //Checks if current_user_on_level($level_id) and returns true or false
if ( current_user_on_level(7) ) {
    <!--Start of Zopim Live Chat Script-->
    <script type="text/javascript">
     window.$zopim||(function(d,s){var z=$zopim=function(c){z._.push(c)},$=z.s=
     d.createElement(s),e=d.getElementsByTagName(s)[0];z.set=function(o){z.set.
     _.push(o)};z._=[];z.set._=[];$.async=!0;$.setAttribute('charset','utf-8');
     $.src='//v2.zopim.com/?0xObfhlxyhOFFN07eRruAdGFbEDphAiO';z.t=+new Date;$.
     type='text/javascript';e.parentNode.insertBefore($,e)})(document,'script');
     </script>
     <!--End of Zopim Live Chat Script-->
          } else {
            // Do nothing
          }

I get an error, that say there is an error on the first line where the JS begins.

Answer 1

Since the code is JS and not PHP you must close the PHP tag and add it as HTML so add a ?> and

if ( current_user_on_level(7) ) {
?>
    <!--Start of Zopim Live Chat Script-->
    <script type="text/javascript">
     window.$zopim||(function(d,s){var z=$zopim=function(c){z._.push(c)},$=z.s=
     d.createElement(s),e=d.getElementsByTagName(s)[0];z.set=function(o){z.set.
     _.push(o)};z._=[];z.set._=[];$.async=!0;$.setAttribute('charset','utf-8');
     $.src='//v2.zopim.com/?0xObfhlxyhOFFN07eRruAdGFbEDphAiO';z.t=+new Date;$.
     type='text/javascript';e.parentNode.insertBefore($,e)})(document,'script');
     </script>
     <!--End of Zopim Live Chat Script-->
<?PHP
          } else {
            // Do nothing
          }
