Question

I have setup a custom post type in WordPress. It is a section where the client can upload documents in PDF format. The documents are divided into two categories – ‘Downloadable Forms’ and ‘Menu’ ; the Custom Field name for the category is ‘document_category’

I am trying to run a query and only display the ‘Downloadable Forms’ on a page. Here is the code I normally use — I’m hoping someone can help me add what I need to make it work?

<?php       
$args = array('post_type' => 'prep_forms', 'posts_per_page' => -1);
// The Query
$the_query = new WP_Query( $args );
// The Loop
$i = 0;
while ( $the_query->have_posts() ) : $the_query->the_post();
?>
<li><a href="<?php echo get_field('document_pdf_file'); ?>"><?php the_title(); ?></a></li>
<?php
$i++;
endwhile;
// Reset Post Data
wp_reset_postdata();
?>

Thanks.

<?php       
$args = array('post_type' => 'prep_forms', 'posts_per_page' => -1);
// The Query
$the_query = new WP_Query( $args );
// The Loop
$i = 0;
while ( $the_query->have_posts() ) : 
    $the_query->the_post();
    // Get all Advanced custom fields
    $my_custom_fields = get_fields(get_the_ID());
    // Does document_category field exists and is it equal with 'Downloadable Forms'?
    if(isset($my_custom_fields['document_category']) && $my_custom_fields['document_category'] == 'Downloadable Forms'):
?>
<li><a href="<?php echo get_field('document_pdf_file'); ?>"><?php the_title(); ?></a></li>
<?php
    endif;
$i++;
endwhile;
// Reset Post Data
wp_reset_postdata();
?>

I’ve used the get_fields($post_id = false) function of the Advanced Custom Fields plugin that returns an array of all the posts’ custom fields and then filtered it to match your needs.

Hope i’ve helped
