Where do I add facebook open graph tags?

I've added a facebook like button to my main page and it's working fine. Now I have to add the Facebook open graph tags ... but I have no idea where to place them. I read somewhere that they should be addedf to the index.php file. I did that (placing them between appropriate html opening and closing tags, etc.) but it caused a server error when I tried to access my site. I read elsewhere that it should be placed in the common header tpl file, but that didn't work either.

I've spent hours searching the forum for help on this, but I haven't found any info that relates. Any assistance would be very much appreciated.

Click the "Free Software Add Ons" up the top of this page
You will find 4 or 5 mods there that maybe will give you inspiration.

Also it depends on what you are trying to achieve
For instance if you want each "product" to have a like button then you put the OG tags in
\includes\templates\YOUR_TEMPLATE\common\html_header.php

I placed the FB like button on my main page. I'm not interested in having a like button on every product page.

I looked through the software add-ons, but didn't see one that addressed this issue. I'll look again, but I'm not hopeful. :unsure:

Thanks.

Thank you, Dr. Byte. :clap:
Whew! I've got it now and it's working great.

For the sake of those who, in the future, may be looking for the answer to the same question I had, what i did was add the Facebook open graph tags to my custom html_header.php file. (Don't forget to back up your files before modifying them!)
