While using the Custom Fields Plugin, I cannot get it to return any data.
I have created a field group called book_cover_thumbnail which has one post linked to it. Can anyone see why the code below would not work?
<img src="<?php get_field('book_cover_thumbnail');?>" />
I get no errors at all, no white space.
Make sure you are a) Echoing the field using either the_field() or echo get_field(), and b) this code is either within the wordpress loop like this:
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>`
<img src="<?php echo get_field('book_cover_thumbnail');?>" />
<?php end while; endif; ?>`
Or you add the post id to the get_field() function as a parameter:
$post_id = *your_post_ID_here*;
<img src="<?php echo get_field('book_cover_thumbnail', $post_id);?>" />

['url'], or for a thumbnail sized image `['sizes']['thumb']['url']. For an ID, you'd have to use that ID to get the item you'd, most likely using a Wordpress function like wp_get_attachment($image_ID, 'thumbnail');, but without knowing the specific usage it's hard to say.Change get_field to the_field. Get field returns the value but doesn't echo it.
Alternatively, put an echo in front of the get field.
Little bit late but also important nevertheless:
You can change the "Return Format" in Custom Fields -> Field Groups -> Return Format You have the choice between value/label and both(array)
Maybe that could help you in this case
