Hi Swati,
by user id, you mean the numeric user id or the alphabetic username?

Thank you

Hi Swati,
Thank you for clarifying.

Please put the following code in your bp-custom.php

/**
 * Search a member list by the user id
 */
function buddydev_search_member_by_user_id( $args ) {

	if ( empty( $args['search_terms'] ) ) {
		return $args;
	}

	$term = $args['search_terms'];

	if ( is_numeric( $term ) ) {

		$args['include'] = absint( $term ); // only this user please
		$args['search_terms'] = ''; // reset search term
	}

	return $args;
}

add_filter( 'bp_after_has_members_parse_args', 'buddydev_search_member_by_user_id' );

Now if you use numeric id in the directory search form, it will list that user.

Hope that helps.

Hi Swati,
Thank you.

You can use the following code to do that

/**
 * Search a member list by the user id with prefixed username
 */
function buddydev_search_member_by_user_id( $args ) {

	if ( empty( $args['search_terms'] ) ) {
		return $args;
	}
	$prefix = strtolower( "INDIA77" ); // Change the prefix if you are using a different prefix

	$term = strtolower( trim( $args['search_terms'] ) );

	if ( stripos( $term, $prefix )  === 0 ) { //must start with
		$id = str_replace( $prefix, '', $term );
		$args['include'] = absint( $id ); // only this user please
		$args['search_terms'] = ''; // reset search term
	}

	return $args;
}

add_filter( 'bp_after_has_members_parse_args', 'buddydev_search_member_by_user_id' );

here we are making sure that our search term starts with the “prefix” and then we replace the prefix to find the id. rest is same.

Hope that helps.
