Need OpenGraph Help

Open Graph is meant to let you set the title, description and image (and other data) to make your preview posts even better. JFBConnect includes some Open Graph plugins to automatically detect the best data to use in various extensions, so, for instance, your Joomla articles can be scanned and have the first image always set as the Open Graph image to use.

If we don't have an Open Graph plugin for the extension you're using, you can always manually set the tags for a page with the following Easy Tag:That tag can be inserted into the layout file for whatever extension you're using as well and use some PHP tags to automatically set the image using information from the extension as well.

I hope that helps explain, but if you have any other questions, just let me know.

Thanks,
Alex

Yes, the above code should work to set the og:title tag.

To expand on what Alex mentioned, there are a few different ways to set the Open Graph tags on the page:
1. Through our Open Graph plugins (as mentioned)
2. Through the Open Graph easy tags (as mentioned)
3. Through the JFBConnect > Open Graph > Configuration > Defaults setting. From here, you can set a default that will be used on pages where #1 and #2 are not found.
4. JFBConnect also attempts to automatically set some values for the following from values in the metadata/Joomla config: url, title, description, type, locale, site_name.

Since the $page_title variable is PHP and needs to be executed for each page, you couldn't put this in the default area mentioned in #3. However, you could do a template override for whatever article component you're using and add the JFBCLogin easy-tag there. This way, you wouldn't have to go into each article to add it.

I hope this helps explain a little further, but if you run into issues when you're adding the Open Graph tags, please let us know.

We cross-posted, so my response to:

Actually my problem might be different than I thought.

If you paste this link:
transactiondirecte.com/index.php?option=...ils&id=31&Itemid=183

Into this tester:
coveloping.com/tools/open-graph-tag-tester

You get the image, the title, description and everything.
Yet when I post the same link to facebook, I get no image and just the site name as a title and description...

If you run the URL on our site socialdebug.com too, you will get the valid image, description, etc. That is good and means that your Open Graph tags are set up on your page correctly. However, Facebook is having a hard time connecting to your site to scrape. When I used the Facebook Open Graph Debugger, there was a warning that Facebook had not scraped your page yet. When I fetched the new scrape information there, I get a Curl/Encoding Error.

Could you try the tips in our Common Support Questions for "My Share Preview is incorrect" at www.sourcecoast.com/jfbconnect/docs/common-support-questions/ specifically pay attention to step 3, as the error I see after the re-scrape is usually caused by GZip. Let me know if this helps to resolve your issue.

Great! Glad that could get you going. If you run into any further problems, please let us know.

Finally, if you haven't already, please consider leaving a review for JFBConnect on the Joomla Extension Directory. While it's absolutely not required, we'd certainly appreciate it.
