Calling for specific fields and show them on the page

Hi, the following is kind of difficult to explain, so let’s hope I succeed in doing so. What I basically need to do is automatically show certain content felds on my portfolio pages. For example:

I have hundreds of customers which I added in the portfolio section. I’ve added the whole list of customer logo’s on a page. When visitors click on a customer logo to see the customer details page, they get details such as a quote, pictures, downloadable pdf files, and so on. This information is added through the Avia Layout Builder.

BUT, above the content of the Avia Layout Builder, I want to automatically show the following elements, because most customer detail pages will consist ONLY this info and it’s therefore a big timesaver to make this happen automatically:
– Show the customer logo (featured image)
– Show the customer name (page title)
– Show the customer country (assigned category)
– Show the customer website link (custom field added with Simple Fields plugin)

On top of that, I’d like to be able to layout it somewhat so that the logo is placed to the left of the title+country+website. I’ve already tried adding some php in the single-portfolio.php file, but my PHP knowledge is very limited and I keep getting errors.

To call for the correct fields, I think it’s something like:
– Featured image: the_post_thumbnail( );
– Page title: the_title( );
– Assigned category: get_the_term_list( get_the_ID() )
– Simple Fields custom field: $customers_website = simple_fields_get_post_value(get_the_id(), array(3, 1), true);

Below is an example of the code I’ve put together, which still has an error and seems to replace any content inside the Avia Layout Builder, but as I explained it’s supposed to just show above it.

<?php 
echo "<div style='float:left; border:1px solid #E1E1E1; margin-right:5%; margin-bottom:20px;'>";
if ( has_post_thumbnail() ) { // check if the post has a Post Thumbnail assigned to it.
the_post_thumbnail( );
} 
echo "</div>";
the_title( '<h3>', '</h3><p>' ); 
			   
echo strip_tags (
get_the_term_list( get_the_ID(), 'customers_entries' )
);
$customers_website = simple_fields_get_post_value(get_the_id(), array(3, 1), true);
echo "</p><p><a href='$customers_website' target='_blank'>$customers_website</a></p>";
?>

Any advice is greatly appreciated.
Thanks in advance!
