FIltering specific visible custom fields

Yes: the list of custom fields is passed through the relevanssi_index_custom_fields filter hook. The filter hook gets an array of custom field names as the parameter, you can remove the ones you don’t like and return the rest.

add_filter('relevanssi_index_custom_fields', 'rlv_skip_custom_fields');
function rlv_skip_custom_fields($custom_fields) {
  $unwanted_fields = array('not_this_field', 'this_one_either');
  $custom_fields = array_diff($custom_field, $unwanted_fields);
  return $custom_fields;
}

Thank you Mikko.

I can’t seem to get this solution to work, but let me make sure I’m following you correctly.

I added the following:

add_filter('relevanssi_index_custom_fields', 'rlv_skip_custom_fields');
function rlv_skip_custom_fields($custom_fields) {
  $unwanted_fields = array('cmtt_synonyms', 'cmtt_variations');
  $custom_fields = array_diff($custom_field, $unwanted_fields);
  return $custom_fields;
}

In this example, I want to filter/prevent the custom fields cmtt_synonyms and cmtt_variations from appearing in my search results. I added that filter and then reindexed, but they are still appearing in my search results. Did I miss anything?

You’ve got the wrong variable name in there:

$custom_fields = array_diff($custom_field, $unwanted_fields);

Should be $custom_fields, not $custom_field.

Thank you, Mikko. I changed that, resulting in the code below. I then reindexed, but the same custom fields are appearing in my snippets. Any other ideas?

add_filter('relevanssi_index_custom_fields', 'rlv_skip_custom_fields');
function rlv_skip_custom_fields($custom_fields) {
  $unwanted_fields = array('cmtt_synonyms', 'cmtt_variations');
  $custom_fields = array_diff($custom_fields, $unwanted_fields);
  return $custom_fields;
}

Thank you!

Do a var_dump($custom_fields) to make sure the strings in your $unwanted_fields array are actually the field names being used in $custom_fields.

You’ll see the result of the var_dump() on the Relevanssi admin page when you reindex.
