I sent the author Jon an email last week about it, and he said hes real close to releasing the next version which has pinterest.
To hold you over, here are the code changes required to get an “inline” Pin It button into the Socialize plugin.
In plugins/socialize/socialize-services.php
Around line 437, add this:
// Create Pinterest button
function createSocializePinterest($service = "", $service_options = array(), $socialize_settings = null){
// thumbnail url
$thumb = wp_get_attachment_image_src( get_post_thumbnail_id(get_the_ID()), 'thumbnail' );
$thumb_url = $thumb['0'];
$buttonCode = '<a href="https://pinterest.com/pin/create/button/?url='.get_permalink().'&media='. $thumb_url . '" class="pin-it-button" count-layout="horizontal">Pin It</a><script type="text/javascript" src="https://assets.pinterest.com/js/pinit.js"></script>';
return $buttonCode;
}
plugins/socialize/frontend/socialize-frontend.php
Around line 68, add this:
case 26:
return $socializeWPservices->createSocializePinterest();
break;
Around Line 137, add 26 to the array like so:
$inline_buttons_array = array(1,2,3,4,5,6,7,8,9,10,22,24,26);
plugins/socialize/admin/socialize-admin.php
Around line 807, add 26 to the array like so:
$inline_buttons_array = array(1,2,3,4,5,6,7,8,9,10,22,24,26);
Around line 842, add this:
$service_names_array[26] = "Pinterest";
