Getting the user picture URL when Gravatar is installed

Question

I'm trying to print a user's picture without the link to the user's profile which is what theme('user_picture', array('account' =>$user_item)) will render. If I use image_style_url('thumbnail', $user->picture->uri) the Gravatar hook will not be called.

So far the only way I have found to do this is:

if (function_exists('_gravatar_get_account_user_picture')) {
    $picture = _gravatar_get_account_user_picture($user);
} else {
    $picture = $user->picture->uri;
}
if (file_valid_uri($picture)) {
    $picture = image_style_url('thumbnail', $picture);
}

But this isn't very elegant, especially since I am developing a module and I'd rather not have to explicitly call the Gravatar module.

Any suggestions?

Thanks!

Answer 1

The reason calling theme('user_picture') returns the user picture as a link is because it's hard coded into the gravatar_preprocess_user_picture() function (see lines 148 and 156 of the gravatar.module file).

This function uses _gravatar_get_account_user_picture() itself so your options are:

• Use that function directly as you're doing at the moment
• Hack the gravatar_preprocess_user_picture() function to return the <img> tag without the link
• Perform some sort of hideous regex on the rendered HTML in your own preprocess function to extract the <img> tag

Personally I'd say the first option is the most desirable.

A slightly more 'Drupal' way to do it might be to use module_exists() instead of checking for the existence of the function itself. It returns TRUE:

if the module is both installed and enabled

While that's not ideal it's a tiny bit more elegant, and if you're worried about the length of code you could shorten it a bit:

$uri = module_exists('gravatar') ? _gravatar_get_account_user_picture($user) : $user->picture->uri

if (file_valid_uri($uri)) {
  $options = array('style_name' => 'thumbnail', 'uri' => $uri, 'alt' => 'Alt');
  $img_html = theme('image_style', $options);
}

The above code generates the HTML for the <img> tag directly using theme_image_style() without having to get the URI directly which I think is what you're after.

Obviously, handling directly in the Gravatar module would be best, but another option (though slightly hackish) would be to simply

$img = strip_tags(theme("user_picture", array('account' => $user_item)), "<img>");
