At the moment the class getCaSeSt returns staff for all locations, the select statement below shows staff id's in a particular location/zip code
      
SELECT id FROM `wp_ab_staff` WHERE id IN (
		SELECT staff_id FROM wp_ab_staff_locations WHERE location_id = (
		SELECT id FROM `wp_ab_locations` WHERE `title` = '3109'
	))

Open in new window


       
Can this be added to class getCaSeSt below as an additional where clause?

	abstract class Config
{
    /**
     * Get categories, services and staff members for drop down selects
     * for the 1st step of booking wizard.
     *
     * @return array
     */


        public static function getCaSeSt()
    {
        $result = array(
            'categories' => array(),
            'services'   => array(),
            'staff'      => array(),
        );

        // This array is for collecting staff members for compound services.
        $staff_members = array();
        // Select all services (with categories and staff members)
        // which have at least one staff member assigned.
        $rows = Entities\Service::query( 's' )
            ->select( '`s`.`id`    AS `service_id`,
                IFNULL(`c`.`id`,0) AS `category_id`,
                IFNULL(`c`.`name`, \'' . Query::escape( __( 'Uncategorized', 'bookly' ) ) . '\') AS `category_name`,
                IFNULL(`s`.`title`, \'' . Query::escape( __( 'Untitled', 'bookly' ) ) . '\') AS `service_name`,
                `c`.`position`     AS `category_position`,
                `s`.`position`     AS `service_position`,

Yes, but you should restructure the query to properly use JOINs.  For example:
SELECT staff.id FROM `wp_ab_staff` staff INNER JOIN `wp_ab_locations` loc ON staff.location_id=loc.id WHERE loc.title=3109

Open in new window


With that, you can add an optional parameter to getCaSeSt():
public static function getCaSeSt($location=NULL)

Open in new window


Now replace you query construction with something like this:
        $query= Entities\Service::query( 's' )
            ->select( '`s`.`id`    AS `service_id`,
                IFNULL(`c`.`id`,0) AS `category_id`,
                IFNULL(`c`.`name`, \'' . Query::escape( __( 'Uncategorized', 'bookly' ) ) . '\') AS `category_name`,
                IFNULL(`s`.`title`, \'' . Query::escape( __( 'Untitled', 'bookly' ) ) . '\') AS `service_name`,
                `c`.`position`     AS `category_position`,
                `s`.`position`     AS `service_position`,
                `s`.`type`         AS `service_type`,
                `s`.`visibility`   AS `service_visibility`,
                `st`.`id`          AS `staff_id`,
                `st`.`position`    AS `staff_position`,
                `st`.`full_name`   AS `staff_name`,
                `ss`.`capacity`,
                `ss`.`price`' )
            ->innerJoin( 'StaffService', 'ss', 'ss.service_id = s.id' )
            ->leftJoin( 'Category', 'c', 'c.id = s.category_id' )
            ->leftJoin( 'Staff', 'st', 'st.id = ss.staff_id' );
if (!is_null($loc)) {
  $query->innerJoin('Location', 'loc', 'st.location_id=loc.id')
    ->where('loc.id', $loc);
}
$rows=$query->where( 's.type',  Entities\Service::TYPE_SIMPLE )
            ->whereNot( 'st.visibility', 'private' )
            ->fetchArray();

Thanks for your comments, it's nearly there.

I created a staff locations class as below

<?php // Andrew E added 11/10/2016
namespace Bookly\Lib\Entities;

use Bookly\Lib;

/**
 * Class StaffLocations
 * @package Bookly\Lib\Entities
 */
class StaffLocations extends Lib\Base\Entity
{
    protected static $table = 'ab_staff_locations';

    protected static $schema = array(
        'id'            => array( 'format' => '%d' ),
        'staff_id'      => array( 'format' => '%d', 'reference' => array( 'entity' => 'Staff' ) ),
        'location_id'   => array( 'format' => '%d', 'reference' => array( 'entity' => 'Location' ) ),
    );

    protected static $cache = array();

    /** @var Service */
    public $service = null;

}

Open in new window


and then added left join and where clause as per below, just need to work how to include variable $customer_location instead of hardcoded value of 759?


		$customer_location = $_SESSION['my_location_id'];
                //if customer location is blank use 3001 
		if ($customer_location = '') $customer_location = '3001';
		
		
        // Select all services (with categories and staff members)
        // which have at least one staff member assigned.
        $rows = Entities\Service::query( 's' )
            ->select( '`s`.`id`    AS `service_id`,
                IFNULL(`c`.`id`,0) AS `category_id`,
                IFNULL(`c`.`name`, \'' . Query::escape( __( 'Uncategorized', 'bookly' ) ) . '\') AS `category_name`,
                IFNULL(`s`.`title`, \'' . Query::escape( __( 'Untitled', 'bookly' ) ) . '\') AS `service_name`,
                `c`.`position`     AS `category_position`,
                `s`.`position`     AS `service_position`,
                `s`.`type`         AS `service_type`,
                `s`.`visibility`   AS `service_visibility`,
                `st`.`id`          AS `staff_id`,
                `st`.`position`    AS `staff_position`,
                `st`.`full_name`   AS `staff_name`,
                `ss`.`capacity`,
                `ss`.`price`' )
            ->innerJoin( 'StaffService', 'ss', 'ss.service_id = s.id' )
            ->leftJoin( 'Category', 'c', 'c.id = s.category_id' )
            ->leftJoin( 'Staff', 'st', 'st.id = ss.staff_id' )
	    ->leftJoin( 'StaffLocations', 'stl', 'stl.staff_id = st.id' ) #added 
	    ->where( 'stl.location_id',  '759' ) #added 
            ->where( 's.type',  Entities\Service::TYPE_SIMPLE )

Then just replace '759' with $customer_location.

Thanks Steve, I am sure I tried that and it didn't work, but it's working now.
