Metatag: Google+ ----------------- This module adds support for meta tag configuration for Google+ Snippet [1]. The following Google+ tags are provided: * itemprop:name * itemprop:description * itemprop:image Also itemtype is provided to add schema in the HTML markup as follows: Usage -------------------------------------------------------------------------------- Page type (itemtype) provides default type options from the Google+ Snippet page [1]; to add other types either install select_or_other module [2] or use the Metatag hooks (see metatag.api.php). Known Issues -------------------------------------------------------------------------------- - When using Zen or its derived theme, the RDF Namespaces will be serialized into an RDFa 1.1 prefix attribute, which means itemtype will be included in prefix="...". To avoid this problem, this module will not add a itemtype directly to $variable['rdf_namespaces'], instead, it will be necessary to add code manually in the template.php or the custom theme. Example code to use and adapt as needed: /** * Implements template_preprocess_html(). * * Add itemtype code for Google+ in the 'html_attributes_array' which is only * available in Zen theme. Note Zen will convert rdf_namespaces to RDFa 1.1 with * prefix, so putting itemtype there will cause it to be added to the * prefix="itemtype=..." attribute. * * @see zen_preprocess_html() */ function MYTHEME_preprocess_html(&$variables, $hook) { if (module_exists('metatag_google_plus') && isset($variables['itemtype'])) { $variables['html_attributes_array']['itemscope itemtype'] = "http://schema.org/{$variables['itemtype']}"; } } Credits / Contact -------------------------------------------------------------------------------- Originally developed by Eric Chen [3] and sponsored by Monkii [4].
