Plugin: ViewSiteLink

[cumbe]

Hello,

i think that it should be so:

Code:

<?php

/*  Plugin Name: ViewSiteLink
    Adds an obvious link in admin navigation that opens home page in new tab.
    Version: 1.0
    Author: Michel Staake
    Author URI: http://michelstaake.me/
*/

$viewsitelink=basename(__FILE__, ".php");

register_plugin(
      $viewsitelink,
    'ViewSiteLink',
    '1.0',
    'Michel Staake',
    'http://michelstaake.me/',
    'Adds an obvious link in admin navigation that opens home page in new tab.',
    'plugins',
    'viewsitelink'
);

add_action('nav-tab','viewsitelink');

function viewsitelink() {
    global $SITEURL;
    echo '<li class="rightnav"><a target="_blank" class="first" href="'.$SITEURL.'" style="
    border-radius: 3px;
    margin-left: 3px;
    border-left: none;
    ">View Site</a></li>';
}

?>

Regards.
