HI Alex,
I am sorry for the delayed reply.

I have been thinking a solution about it. There is a solution without BuddyPress Friends suggestions pro though. xprofile query are costly(slow), so I am not sure if we should do that or not.

The approach is to first create a xprofile query builder or this field

function bpfscustom_get_multiselect_field_query( $user_id, $field_id, $match_field_id, $compare ) {

	$field_data = xprofile_get_field_data( $field_id, $user_id );

	if ( empty( $field_data ) ) {
		return array();
	}

	if ( ! is_array( $field_data ) ) {
		return array(
			array(
				'field'   => $match_field_id,
				'value'   => $field_data,
				'compare' => $compare,
			)
		);
	}

	$query = array();
	foreach ( $field_data as $datum ) {
		$query[] = array(
			'field'   => $match_field_id,
			'value'   => $datum,
			'compare' => $compare,
		);
	}

	return $query;
}

and then use it in the bp-friend-suggestions-pro-functions.php near line 119

		if ( $rule['field_id'] == ACTUAl_MULTI_SELECT_FIELD_ID ) {
			$queries = bpfscustom_get_multiselect_field_query( $user_id, $rule['field_id'], $rule['match_field_id'], $compare );
			if ( ! empty( $queries ) ) {
				$xp_query = array_merge( $xp_query, $queries );
			}
continue;
		}

You should replace the ACTUAl_MULTI_SELECT_FIELD_ID with the numeric field id for the multi select.

So, the lines in this file which looked like this’

		$xp_query[] = array(
			'field'   => $rule['match_field_id'],
			'value'   => $value,
			'compare' => $compare,
		);

will be

		if ( $rule['field_id'] == ACTUAl_MULTI_SELECT_FIELD_ID ) {
			$queries = bpfscustom_get_multiselect_field_query( $user_id, $rule['field_id'], $rule['match_field_id'], $compare );
			if ( ! empty( $queries ) ) {
				$xp_query = array_merge( $xp_query, $queries );
			}
			continue;
		}

		$xp_query[] = array(
			'field'   => $rule['match_field_id'],
			'value'   => $value,
			'compare' => $compare,
		);

Hope that helps.

I am sorry, I typed values instead of value in the suggested condition.

Here is the correct code.

if( is_array($value)) {
  $value = maybe_serialize( $value );
}

Please try it.

Hi Alex,
Please make sure you are using maybe_serialize and not maybe_unserialize. The former will always return a serialized string.

Hi,
I am sorry, It seems their support is not able to understand the question.

Simplify the question for them:-

– Is there a function to check if we are on thank you page. Like is_page(‘xyz’) but specific to memberpress? We need the code to check when we are on the thank you page, can you provide that?

I believe they should be able to understand it and help with the code.

Brajesh

Hi Kim,
I am sorry, none of those are supported at the moment.

BuddyPress(or our xprofile custom field types) do not have the ability to import profile field data.
