Create Schema in WordPress with PHP

I have a website that gets fed data from a local MLS. I put together PHP to grab the title of the page which contains the address & MLS # of the current property, and create schema for it. I also collect some information from meta and compase the image url based on known information. However, when I use the code below, my site becomes slow and starts to crash. I have put the script below just above the ending body tag, below wp_footer(). I would feel better about myself if the problem was something complex, but it is probably something dumb. Thank you in advance.

 $path="http://" . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];//gets url of current page $tags = get_meta_tags($path); //retrieves an array of all meta name tags $description= $tags['og:description']; // tag containing the property descriion $the_address= explode(",",ucwords(strtolower(get_the_title())) ); //get post title, parse address parts $street=$the_address[0]; $city =$the_address[1]; $add2 = explode ("(", $the_address[2]); $state = strtoupper(substr($the_address[2],1,2)); $zip = substr($the_address[2],4,5); $mls= substr($the_address[2],17,8); echo $mls; $img_url = "https://images.marketleader.com/HouseImages/MFRMLS/".substr($mls,5,3). "/f_". $mls. ".jpg"; $price=""; /*SCHEMA TYPE RESIDENCE */ $schema=""; echo $schema; /*SCHEMA TYPE PRODUCT */ $schema=""; echo $schema; 

Instead of get_meta_tags() which contacts your own web server as if it were a different server, try get_post_meta() which should pull from the initial query. You will want to run this inside the Loop so it gets the postmeta of the currently displayed post.

I don't have a custom post template on this site; is there a way to put this procedure into a function on functions.php? I know how to put it there, just not sure on how to make it run when desired. Thanks!

You could try hooking a function in functions.php to the wp_footer() hook, which would insert your code at the bottom of the page. You would want to add global $post to try to obtain the post object since this would be outside the Loop.
