Opengraph Image tag not being rendered was created by Mark Fallon

Hi,

I am using K2 Version 2.6.8.

The other Opengraph tags are rendered fine (url, title, description & type) but there is no og:image tag, even though the K2 item has an image set.

Any ideas?

Thanks

Mark

Hello Mark,

Have you specified which image size you want to use?
This setting is located in K2's params.

Yes. Tried changing the size as well. No joy.

For some reason it only seems to affect the site on my localhost. The live site works OK... strange.

Another related question: If there is no image in the article, how can I set a default og:image src?

Facebook won't work on localhost.
Yes you can perform an if/else check in your template and if an image is not present you can use the setMetadata function docs.joomla.org/JDocument/setMetaData .

But what am I testing for? I can't run an if/else on the existence of an og:image tag, because wouldn't the template be loaded BEFORE K2? so there will never be an og:image tag at the time the if/else is executed.

I need to find the K2 file that sets the og:image tag so I can amend it. Have you any idea which file it is? I have searched through the file contents of the K2 folder to find "og:image" but no luck.

You do not need to hack K2 core files.
You will lose all your changes when you update.

This has to be done via template overrides.
You need to check if the image is both set and present.

This post will help you on template overrides.

Yes. I know about template overrides. But I do not know which file to override, hence my question.

It's the item.php file.

I can't find any reference to any of the Opengraph meta tags in item.php... can you be more specific?

You do no need to find any reference.

You simply need to add a new metatag if an image is not present.

OK. I could have just done that anyway. I wanted to to keep my code clean by just editing it where K2 sets the meta tag but it seems we don't know where that is.

I have done it the way you suggested instead and although being quite a hacky way, it does work.

It is not hacky.
You get to keep your edits even if you update K2.

If you tried the other way you would have to backup and re-patch K2 after every update.

I wanted to use template overrides to change the correct file and in the correct LOGICAL place.

Placing this code into a random place in a file that doesn't deal with the generation of the og meta tags, IS a hacky way of doing it.

It would make more sense to to edit the relevant code that generates the meta tags, in the relevant file (using a template override obviously), rather than just placing it in any old place in the item.php file.

But I suppose I like to keep my code neat and logical. Other people may not.

Exactly

Some people help you with your project for free while other may don't.
Anyway it works like this.

Either hack core files or change item.php
No other file can be overriden.

I am locking the topic now.
