Ok, I’ve figured out a solution. Another plugin needed to run a newer version of jQuery. The plugin was not removing migrate, nor was it removing the wordpress version of jQuery. But just the fact that it was loading was causing the W3TC scripts to fail.

The solution was to selectively load the newer version of jQuery only on the pages of the plugin that needed it.

Looks great. I’m dropping this into single.php so don’t have to worry about the homepage.

Here is my final version. The only change is adding do_shortcode to $content since it was stripping shortcode out:

function disclosure_filter($content) {

	if (! has_tag('Disclosure') || strpos($content,'</p>') == false) { // exclude any post without "Disclosure" tag or any '</p>'
		$content = do_shortcode($content);
		echo $content;
		return;
	}

	if(is_singular() && is_main_query() && ! is_admin()) {

		$content = do_shortcode($content);

		$disclosure_content = "<div>This is my disclosure</div>";

		$paragraph = explode ('</p>', $content); // separate post content into paragraphs
		$firstp = $paragraph[0]; // select first paragraph

		preg_match('/(<img.*?>)/', $firstp, $image); // select image tag in first paragraph
		$disclosure = '<div class="show-more-wrap disclosure-wrap"><img class="show-more-button" src="'. home_url('/images/icons/warning2.svg') . "\"><p class='show-more-button'>Advertising Disclosure</p>{$disclosure_content}</div>"; // add disclosure content

		$remainder = preg_split('/(<img.*?>)/', $firstp); // select first paragraph content after image

		if ($image) { // if image exists in first paragraph
		echo $image[0]; // print image
		echo $disclosure; // print disclosure
		echo '<p>'; // open new paragraph
		echo $remainder[1]; // print remaining first paragraph content
		}	

		else { // if image does not exist in first paragraph
			echo $disclosure; // print disclosure
			echo $firstp; // print first paragraph
		}

		$therest = implode('', array_slice($paragraph, 1)); // select remaining post content
		echo $therest; // print remaining post content
	}
}
add_filter('the_content', 'disclosure_filter');

genesis();
?>

Thanks for the tip. Here’s what I ended up putting in single.php:

function custom_filter($content) {
	if (! has_tag('custom')) { // exclude any post without "custom" tag
		echo $content;
		return;
	}

	if(is_main_query() && ! is_admin()) {

		$custom_content = 

							'<div><p>content</p></div>';

		$paragraph = explode ('</p>', $content); // separate post content into paragraphs
		$firstp = $paragraph[0]; // select first paragraph

		preg_match('/(<img.*?>)/', $firstp, $image); // select image tag in first paragraph
		$custom = '<div>{$disclosure_content}</div>'; // add disclosure content

		$remainder = preg_split('/(<img.*?>)/', $firstp); // select first paragraph content after image

		if ($image) { // if image exists in first paragraph
		echo $image[0]; // print image
		echo $custom; // print disclosure
		echo '<p>'; // open new paragraph
		echo $remainder[1]; // print remaining first paragraph content
		}	

		else { // if image does not exist in first paragraph
			echo $custom; // print disclosure
			echo $firstp; // print first paragraph
		}

		$therest = implode('', array_slice($paragraph, 1)); // select remaining post content
		echo $therest; // print remaining post content
	}
}
add_filter('the_content', 'custom_filter');

I put the post ID into the shortcode and it pulled all the rest of the data correctly. The other weird thing is that blank box where the thumbnail should be actually links back to the CURRENT page I’m on, not to the page with the post ID I put in the shortcode.

And yes, the post ID does refer to a post with a thumbnail, although the post I’m pasting it into does not have a thumbnail.
