Easily accessing all Pod fields in Pods Framework for WordPress

It’s better than running extract(), which is generally ill-advised, but has the drawback that running ->field() for each individual meta will run many individual requests to the database. As an alternative, get_post_meta( get_the_ID() ) can be called to get all post meta in a single database query, returned as an array. To transform that into individual variables, something like this can be done:

<?php

foreach( get_post_meta( get_the_ID() ) as $key => $value ) {
	if ( '_' === substr( $key, 0, 1 ) ) {
		// Private meta prefixed with underscore.
		continue;
	}
	if ( 1 === count( $value ) ) {
		// Single value or relationship to a single ID.
		${ 'prefix_' . $key } = $value[0];
	}else {
		// Array; relationship to many IDs.
		${ 'prefix_' . $key } = $value;
	}
}
