Hide and show a div depending on session

问题

I have an admin link with a div id "admin". Sessions are started when a user is logged in to show if it is a normal user or an admin. Normal users can't access the files for admin, but can still see the admin link.

Is there a way to make it so normal users can't see the link, using only php or html, without jquery or jscript or any of those.

回答1:

Using interleaved PHP & HTML with standard PHP syntax:

<?php
if ($user_is_an_admin) {
?>
<div id='admin'>
  Only admins can see this...
</div>
<?php
}
?>

Alternate templating syntax:

<?php if ($user_is_an_admin): ?>
<div id='admin'>
      Only admins can see this...
</div>
<?php endif; ?>

Not interleaving, PHP only:

if ($user_is_an_admin) {
  echo "<div id='admin'>
      Only admins can see this...
     </div>
  ";
}

You'll need to use conditionals inside of your views:

<?php if($_SESSION['adminid'] == 1234): ?>
    <!-- Admin div goes here -->
<?php else: ?>
    <!-- Admin link goes here -->
<?php endif; ?>
