Trying to use Advanced Custom Fields with custom image sizes

Question

I have a product section on my wp-site. I am trying to display the attached thumbnail image in specific sizes that are automatically cropped to the right size.

I have used Advanced Custom Fields to create a field called product_thumbnail I have used Additional Image Sizes to create a new image size called products I have used the following code on another word press site and it worked fine, but on my current site it returns empty.

<?php $image = wp_get_attachment_image_src(get_field('product_thumbnail'), 'products'); ?>
<a href="<?php the_permalink(); ?>"><img src="<?php echo $image[0]; ?>" /></a>

I have ran a batch to make sure my images are created if not already. This is boggling my mind. Any help appreciated.

Answer 1

why OH WHY does everybody insist on making custom fields for everything .

is there a special reason that you would want the use of custom fields ? If so, please explain exactly what you want to achieve . If not - a much better approach (and more fool-proof for non-computer-savvy-clients) would be to use the_post_thumbnail(); - like you stated in your question already, with Additional image sizes in the theme .

I do not want to duplicate my answers - so you just as well read here :

Display thumbnail from custom field

Basically you will use

<a href="<?php the_permalink(); ?>"><img src="the_post_thumbnail('your_size_name');" /></a>
