I'm trying to implement Facebook's open graph meta tags (see http://developers.facebook.com/docs/opengraph) on a 1.31.1 store and can't figure out how to generate the og:image tag.

This is the code I have so far. The code for the og:title and og:url are parsing the correct values but I have no idea what code to use to get the correct product image for the og:image tag

<html xmlns:og="http://opengraphprotocol.org/schema/"
     xmlns:fb="http://www.facebook.com/2008/fbml">


   <head>
.......

<meta property="og:title" content="{$meta_title|escape:'htmlall':'UTF-8'}"/>
   <meta property="og:type" content="product"/>
   <meta property="og:url" content="{php} echo 'http://'.$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI']; {/php}"/>
   <meta property="og:image" content=""/>
<meta property="fb:app_id" content="(your developer ID)"/>
   <meta property="og:site_name" content="(your site name)"/>

I'm not a presta developer, but in is the best image url for product, ok? So look to classes/Product and Product::getImages($lang) or Product::getCover($lang) which return product's cover image ID. If you have an ID of a image, you win.

Look at for example to modules/gsitemap to Gsitemap::_postProcess where are generated URLs to sitemap.xml, ones from cms pages, ones for products and ones for images. Ok, I think, that image URL is something like this:

$link = new Link();
ogImageUrl = 'http://'.htmlspecialchars($_SERVER['HTTP_HOST'], ENT_COMPAT, 'UTF-8').'/img/p'.$link->getImageLink($productId.'-'.$imageId);

I answered you?

I'm going to make something similar, but not now, to 3 months later... Do you place your plugin as opensource? I will be continuing in your work.

Ok,

I'm sick today, for worst flu in my life so I had time to done this :)

download from

http://code.google.com/p/prestashop-facebook-opengraph-module/

Your contributions are very welcomed.

This is working plugin implementing META tags from

http://developers.facebook.com/docs/reference/api/

So if page is not product page, it displays site logo and og:type website. If a page is product's page, it displays product image (first from lang_id and product_id) and og:type product.

Enjoy!

If you're having trouble with this great mod, try editing fbopengraph.php and looking for this piece of code.

     //if language is present
    $id_lang = $_GET['id_lang'];
    if (!isset($id_lang)) {
      //if is not present, hardcode lang_id as in www.acidx.cz 
      //change this to whatever language code you actually use  
      $id_lang = 3;
    }
     if ($_DEBUG == 1) {
         echo 'IdLang: '.$id_lang.'';
     }



I had to change $lang_id = 3 to $lang_id = 1 and then it worked fine for me.

Hi guys

 

I have installed the module in my 1.3.1.1 and the Facebook Like button writes the Like to the wall, but an error appears, and the Like button count is 0.

 

"Applikasjons-IDen specifiied in meta tag "fb:app_id" is not alowed on that domain."

 

Please advice :)

Thanks for this!! I've already used it together with prestaloveaddthis module. This module if free for use, but...it has several disfunction like FB open graph, its not included. So I added fbopengraphmodule (I'm using PS 1.4.7 here http://www.luxusni-pradylko.cz) and I had also problems with images....I made change like DFC005 and now its working all fine :-)))

 

THX DFC005 for saving my time!!

Hi

 

So I figured that this code in my header.tpl was interferring with all my other Facebook modules:

 

[color=#000000][font=arial, sans-serif][size=3]<html xmlns:og="[/size][/font][/color][url="http://ogp.me/ns#"]http://ogp.me/ns#[/url][color=#000000][font=arial, sans-serif][size=3]" xmlns:fb="[/size][/font][/color][url="http://www.facebook.com/2008/fbml"]http://www.facebook.com/2008/fbml[/url][color=#000000][font=arial, sans-serif][size=3]">[/size][/font][/color]

 

But this is what the opengraph module says must be added. How can I get Opengraph to work?
