Index Table – Indexing ACF repeater field titles and contents
Using this custom code, you can enable indexing of Advanced Custom Fields repeater field post titles and/or contents for the current post. Change the following variables in the code as you need them
$field_names -> one or more repeater field names, separated by comma
$index_title -> true or false, to index the post titles found in the repeater field
$index_content -> true or false, to index the post contents found in the repeater field
What is this, and where do I put this custom code?
add_filter('asp_index_cf_contents_before_tokenize', 'asp_post_content_before_add_acf_relationship', 10, 2);function asp_post_content_before_add_acf_relationship($content, $post) {$field_names = 'field1, field2'; // Comma separated list of field names$index_title = true; // To index the related post title$index_content = true; // To index the related post content$run_shortcodes = true; // To run shortcodes within Flex element contents// ----------------------------------------------------------------if ( function_exists('get_field') ) {$fn_arr = explode(',', $field_names);foreach ($fn_arr as $field_name) {$field_name = trim($field_name);if ( empty($field_name) )continue;$args = array('p' => $post->ID, // ID of a page, post, or custom type'post_type' => 'any');$my_query = new WP_Query( $args );while ( $my_query->have_posts() ) : $my_query->the_post();$items = get_field($field_name);if ( empty($items) )continue;if ( is_array($items) ) {foreach ($items as $item) {if ( isset($item->ID) ) {if ( $index_title ) {$content .= ' ' . get_the_title($item->ID);}if ( $index_content ) {$content .= ' ' . apply_filters('the_content', get_post_field('post_content', $item->ID));}} else if ( is_array($item) || is_string($item) ) {if ( $run_shortcodes )$content .= ' ' . do_shortcode( wd_array_to_string($item));else$content .= ' ' . wd_array_to_string($item);}}} else if ( is_string($items) ) {$content .= ' ' . $items;}endwhile;}}return $content;}
