Output listing fields on custom profile page

Hello,
I originally asked this question on wordpress.org, I got many tips by Stiofan, but because of lack of my PHP skill, I couldn’t make it.

I created a custom profile page for members, the members can see their listing fields and a map instantly without clicking a link (on Buddypress profile, you have to click ‘Listing’ button to see the member’s listing info. I’d like to show the member’s listing info directly on the custom profile page)

I’d really appreciate if you could let me know how I can make this happen. Previously Stiofan gave me this tip;

$post_info = geodir_get_post_info($customer_post_id);

you could then do a print_r to show the array of info you have access to.

print_r($post_info);

Where should I add those 2 lines? A big apologies to ask a very basic question.
I’ll send you the login details separately.
And thank you so much for your help in advance.
