Restrict Social Image Except For Featured Image

Hi again!

Thank you for opening a new topic. Your inquiry isn’t related to the one where you posted earlier since oEmbed is a different protocol from Open Graph & Twitter Card.

The solution is simple: Only allow featured images to get through the generator via a filter.

The execution for that is not that simple, but here it is:

add_filter( 'the_seo_framework_image_generation_params', function( $params, $args, $context ) {

	// Don't adjust non-social callers, such as Schema.org generators.
	if ( 'social' !== $context ) return $params;

	// When a featured image may be generated, make sure it's the only thing used for generation.
	if ( isset( $args['cbs']['featured'] ) ) {
		$args['cbs'] = array_intersect_key( $args['cbs'], array_flip( [ 'featured' ] ) );
	}

	// Disable fallback images.
	$args['fallback'] = [];

	return $args;
}, 11, 3 );

You can place that in your (child-)theme’s functions.php file or a custom (mu-)plugin.

The filter modifies the image generator. What it does is disable fallback image lookups for all social context-queries (like Twitter Card and Open Graph). It also strips all other callbacks (cbs) but the featured-image-getter. You may want to forgo the cbs array alteration if you still want to allow images from the content to be processed.

The social image you set via the SEO meta settings box always has precedence and is unaffected by this filter.

I hope this helps ??

No problem Sybre, my error.

I appreciate the code here. So this does do what you said. Twitter places the post into a small card and there is no image, just a default image icon twitter adds. That is not going to work out.

I do appreciate you trying to help though!
