how to hook plugin function into custom function in wordpress

Question

In wordpress I am trying to use Advance Custom Field Plugin's function into my own function. I have added

add_action( 'post_link_resource_lessonplans_shortcode', 'the_field' );

before my function and into my function. I have use

do_action('the_field');

but there is no result i can found on the browser so any help? thanks in advance.

Answer 1

Just use the_field($field_name) directly in your custom function. Or

if(function_exists('the_field')){
    the_field($field_name);
}

Anyway the_field function needs at least one parameter.
