Meta Tag Manager and LinkedIn

Hi, it seems property isn’t something in the HTML standards but is widely used via RDFa

Unfortunately, I can’t see an easy way to add this as we don’t have filters, I’ve added this as a ‘todo’ feature, but currently due to time constraints, it’ll be a while.

Hi Marcus,

Many thanks for the response! I do hope you can implement something to make MTM more compatible (and customizable/extensible) for closer integration with posts to LinkedIn and Facebook. This was the main reason I installed MTM, which I thought would be a light weight solution — but I might have to swap to another solution if it’s too far down your to-do list and won’t be addressed for too long of “a while”.

Thanks again.

Yup, I’d love to see it happen sooner, but it’s a time-issue, I just don’t have any right now ?? Maybe in a few weeks this may be possible.

What I could do now is add a filter and provide a simple snippet that’d convert things with name=”image” to name=”image” property=”og:image”, would that work? You may need to modify it to expand on further properties, e.g. copy/paste one line and modify the text.

I think your simple quick fix could work, if the instructions on how to install/use the snippet fall within my level of expertise (not a superuser). Worth a try I suppose, and perhaps I can get some help from a local if needed.

Thanks!

OK, so get the development version from here:
https://www.ads-software.com/plugins/meta-tag-manager/advanced/

Then add this filter to your functions.php file in your theme, or somewhere else appropriate:

add_filter('mtm_tag_output', function( $tag_string, $MTM_Tag ){ /* @var MTM_Tag $MTM_Tag */
	if( $MTM_Tag->type == 'name' ){
		$values = array('image'); // add to this for more tags
		if( in_array($MTM_Tag->value, $values) ){
			$tag_string = str_replace('name=', 'property="og:'.$MTM_Tag->value.'" name=', $tag_string);
		}
	}
	return $tag_string;
}, 10, 2);

if you want MTM to make it happen for description too, for example, then add it to the array like so:

$values = array('image', 'description'); // add to this for more tags

Hope that helps! We’ll probably be making some sort of automated way to handle this in the future, but I dont’ know when exactly.
