Query pages for use of a flexible content layout

  • I have a site that originally used a repeater field for selecting layout options. I now use the flexible content field. I need to be able to query the site for pages that use “featured-resources” as a row layout.

    In the past, I could query sub-fields of the repeater field using this within a custom template:

    function query_subfields( $where ) {
    	$where = str_replace("meta_key = 'mods_$", "meta_key LIKE 'mods_%", $where);
    	return $where;
    add_filter('posts_where', 'query_subfields');
    $args = array(
    'posts_per_page'	=> -1,
    'post_type'		=> 'page',
    'meta_query'	=> array( array(
    'key'		=> 'mods_$_choose_module',  // WHAT REPLACES choose_module ??
    'value'		=> 'Featured Resources',
    'compare'	=> '='
    $the_query = new WP_Query( $args );
    <?php if( $the_query->have_posts() ): ?>
    <?php while( $the_query->have_posts() ) : $the_query->the_post(); ?>
    <li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
    <?php endwhile; ?>
    <?php else : ?>
    <p>No matches.</p>
    <?php endif; ?>
    <?php wp_reset_query(); ?>

    Now that I’m using flexible content, I don’t know how to define the 2nd part of the key. Content templates use get_row_layout(); to add field contents to pages, but this is not a key. From what I’ve read, I believe the key for these sub-fields is randomly generated. How do I allow for this, so that I’m able to generate a list of pages using this row layout?

  • In the DB the flex field is stored as an array of layout names.

    $flex_field_name = 'name of your flex field here';
    $layout_name = "name of your layout here";
    $args = array(
      'post_type' => 'page',
      'posts_per_page' => -1,
      'meta_query' => array(
          'key' => flex_field_name,
          'value' => '"'.$layout_name.'"'
          'compare' => 'LIKE'
  • Very close! We just need a $ sign in front of that key variable, and it works!

    'key' => $flex_field_name,

    Thanks much! Mean it!
