如何获取meta_key的值并将其发布在任何页面上

I have this in database:

I want to post the meta_value. How to do that? I want for each post_id to post the assigned meta_value on the same page, and that automatically.

How I can retrieve the meta_value and post it?

Try this in your single.php or custom-post-type-single.php

<?php $key_values = get_post_meta( get_the_ID(), 'property_bathrooms' ); ?>
