Ans:
Relationship:
A Relationship column is essentially a select list containing items from the related type.

The following code will retrive the related field:

Ans:

1. $var = array( ‘limit’ => -1, ‘where’ => “field_name.meta_value =’$some_value'”);
2. $var = array( ‘limit’ => -1, ‘where’ => “t.field_name =’$some_value'”);
3. $var = array( ‘limit’ => -1, ‘where’ => “pod_name.name =’$some_value'”);

get_field Use.
get_field:
This is a very versatile function. we can use to store the value, echo a value and interact with a value. And note the type of variable returned is relative to the field type.
For Ex. A repeater will return a multidimensional array.

Parameters:
<?php $field = get_field($field_name, $post_id, $format_value); ?>

$field_name: the name of the field to be retrieved. eg “page_content” (required)
$post_id: Specific post ID where your value was entered. Defaults to current post ID (not required). This can also be options / taxonomies / users / etc
$format_value: whether or not to format the value loaded from the db. Defaults to false (not required).
