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
- $index_content -> true or false, to index the post contents found in the repeater field
add_filter('asp_index_cf_contents_before_tokenize', 'asp_post_content_before_add_acf_relationship', 10, 2);
function asp_post_content_before_add_acf_relationship($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
// ----------------------------------------------------------------
