Home Forums Add-ons Repeater Field If Subfields Equals, Show Posts Reply To: If Subfields Equals, Show Posts

  • Hi @fredjs and @chromasites

    There are some information regarding querying subfield here: http://www.advancedcustomfields.com/resources/query-posts-custom-fields/

    @fredjs first off you should never use query_posts.. it’s been shunned by developers for quite some time. Instead use either pre_get_posts filter to modify a core query or the WP_Query class to create a new query.

    You have not told me the fieldname of your repeater field so in this example it’s written as “repeaterfieldname”. For the examples to work you need to replace these.

    Put this in the template where you want to display the posts:

    
    <?php
    // args
    $args = array(
    	'posts_per_page'	=> -1,
    	'post_type'		=> 'profiles',
    	'meta_query'	=> array(
    		'relation'		=> 'AND',
    		array(
    			'key'		=> 'repeaterfieldname_%_year',
    			'compare'	=> '=',
    			'value'		=> '2015',
    		),
    		array(
    			'key'		=> 'repeaterfieldname_%_level',
    			'compare'	=> '=',
    			'value'		=> 'grand prize',
    		)
    	)
    );
    
    // query
    $the_query = new WP_Query( $args );
    ?>
    <?php if( $the_query->have_posts() ): ?>
    	<ul>
    	<?php while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
    		<li>
    			<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
    		</li>
    	<?php endwhile; ?>
    	</ul>
    <?php endif; ?>
    
    <?php wp_reset_query();	 // Restore global post data stomped by the_post(). ?>
    

    And this should go in your themes functions.php:

    
    // filter
    function my_posts_where( $where ) {
    	
    	$where = str_replace("meta_key = 'repeaterfieldname_%", "meta_key LIKE 'repeaterfieldname_%", $where);
    
    	return $where;
    }
    add_filter('posts_where', 'my_posts_where');
    

    Please note that if your sub fields are in different repeaters you need to do a replace on both of these in the my_posts_where function:

    
    // filter
    function my_posts_where( $where ) {
    	
    	$where = str_replace("meta_key = 'repeaterfieldname_%", "meta_key LIKE 'repeaterfieldname_%", $where);
    $where = str_replace("meta_key = 'repeaterfieldname2_%", "meta_key LIKE 'repeaterfieldname2_%", $where);
    
    	return $where;
    }
    add_filter('posts_where', 'my_posts_where');
    

    Try it out!
