Need help with conditional redirect from post

https://www.dropbox.com/s/wjf2tvt4y6qpnce/add-category-button.zip?dl=0

here’s a simple plugin that will create a link after the content of any post where the slug is a match in a case/switch statement. You’ll need to edit the php and css to suit your needs as your request doesn’t have enough information to make something fully fleshed out.

the relevant code:

function add_category_button_tug23f8(){
	$found = 0;
	if(is_single()) {
		global $post;
		$postcat = get_the_category( $post->ID );
		$slug = $postcat[0]->slug;
		$url = '';
		
		/* make the links */
		switch ($slug) {
			case 'pancakes':
				$url = "/your-link-here/pancakes";
				$found = 1;
				break;
			case 'waffles':
				$url = "/your-link-here/wafles";
				$found = 1;
				break;
			/* etc... */
		}

		if($found){
			add_filter('the_content', function ($content) use ($postcat, $url) {
					/* make the button */
					$after = '';
					$after .= '<div class="acb-wrapper">'."\n";
					$after .= '<a href="'. $url .'" class="acb-button">'. $postcat[0]->name .' Program</a>'."\n";
					$after .= '</div>'."\n";
					$content = $content . $after;
					return $content;
			}, 10, 2);
		}
	}
}

The important stuff here is eg:

case 'pancakes':
     $url = "/your-link-here/pancakes";
     found = 1;
     break;

You set each case with a slug, then you set the url variable per slug.

This might be a lot to do if you have a ton of categories you need this for but you didn’t provide any information as to your url structure or a link to your diabetes program.
