Gravatar Image Still Not Loading Open Cart Admin - php

Question

Hi I am trying to get my gravatar api working with my open cart admin/controller/common/header.php and my admin/view/template/common/header.tpl
Still not working gave it ago before that some one gave me advice on but now not working? So thought give it ago another way but nothing.
admin / controller/ header. php
This is just trimmed down version
<?php
class ControllerCommonHeader extends Controller {
protected function index($get_gravatar) {
}
function get_gravatar( $email, $s = 80, $d = 'mm', $r = 'g', $img = false, $atts = array() ) {
$url = 'http://www.gravatar.com/avatar/';
$url .= md5( strtolower( trim( $email ) ) );
$url .= "?s=$s&d=$d&r=$r";
if ( $img ) {
$url = '<img src="' . $url . '"';
foreach ( $atts as $key => $val )
$url .= ' ' . $key . '="' . $val . '"';
$url .= ' />';
}
return $url;
}
admin / view / template / common / header.tpl
<?php
$email = $user_info['email']; // Not Working "Need it to pick up who ever logins"
$email = "your#rmail.com"; // Works
$default = "http://www.somewhere.com/homestar.jpg";
$size = 150;
?>
<li>
<a href="" class="text-center">
<img src="<?php echo $grav_url = "http://www.gravatar.com/avatar/" . md5( strtolower( trim( $email ) ) ) . "?d=" . urlencode( $default ) . "&s=" . $size;; ?>" alt="" />
</a>
</li>

Changes for getting gravatar image in header.tpl
Update system/library/user.php as below:
After: $this->username = $user_query->row['username'];
Add: $this->email = $user_query->row['email'];
Before: public function getUserName() {
Add:
public function getUserEmail() {
return $this->email;
}
Update admin/controller/common/header.php as below:
After: $this->data['logged'] = sprintf($this->language->get('text_logged'), $this->user->getUserName());
Add: $this->data['email'] = $this->user->getUserEmail();
Update admin/view/template/common/header.tpl as below:
<div class="img-circle">
<img src="http://www.gravatar.com/avatar/<?php echo md5(strtolower(trim($email))); ?>">
</div>
Please let me know the result of these changes.
Note: In opencart, you need to assign values to variables like: $this->data['variable_name'] in controller files and use them template files like: $variable_name.

Have you tried adding an extension to your url => www.gravatar.com/avatar/far512q3tgfqwe*.jpg* for example, a quick google search and i came up with this url, check it for further info:
http://en.gravatar.com/site/implement/images/
Try this piece of code in your header.php to get the email of the current logged in user:
$this->load->model('user/user');
$email_data = $this->model_user_user->getUser($this->user->getId());
$email = $email_data['email'];
if you want to get emails for all users it need to be handled differently.
