Service links - Facebook “like” error [closed]

Question

I am using the Service links module in my Drupal 7 site.

When using the Facebook "like" widget, I get the word "error" (in red color), in the place where the Facebook "Like" button should be.

When clicking on the word "Error", a Facebook popup window is opened with the error like so:

The href URL must be absolute

Note: I am using the Service links widgets inside a view. Other Services links widgets are working great, such as the Facebook share widget, Twitter, Google+ and Pinterest widgets.

What is the problem of the Facebook "like" button?

Answer 1

Replace this line(in sites\all\modules\service_links\js\facebook_like.js):

iframe.src = $(this).attr('href').replace('http://', '//').replace(/http[s]*\%3A\/\//, '');

with the below line:

iframe.src = $(this).attr('href').replace('http://', '//');

Answer 2

I also had the problem that the button was not showing up. I tried the patch mentioned by Astha chauhan and pachabhaiya, but it still didn't work. I found the problem after comparing the code given by Facebook Developers with the code generated by the widget: The appId was not included in the iframe src. My fix was to replace the line (in sites\all\modules\service_links\js\facebook_like.js):

iframe.src = $(this).attr('href').replace('http://', '//').replace(/http[s]*\%3A\/\//, '');

with:

iframe.src = $(this).attr('href').replace('http://', '//') + "&appId=" + Drupal.settings.ws_fs.app_id;`
