Laravel join query not working when passing a variable - php

Question

I want to execute a join statment in laravel by passing a php varaiable,Bit its not working when passing a varibale. Following is my code
$loc_services = Clinic::select('*')
->join('locations', 'locations.clinicID', '=', 'clinics.clinicID')
->join('location_services', 'location_services.locationID', '=', 'locations.locationID')
->join('services', 'services.serviceID', '=', $services_id)
->get();
I tried to execute it as statment and got the following
select * from `clinics` inner join `locations` on `locations`.`clinicID` = `clinics`.`clinicID` inner join `location_services` on `location_services`.`locationID` = `locations`.`locationID` inner join `services` on `services`.`serviceID` = `10`
When i directly executed it in phpmyadmin it returns fllowing error
Column not found: 1054 Unknown column '10' in 'on clause', i found that error is triggering because `10` is inside `''` quotes, how can i execute this

Answer 1

You have to pass $services_id in where cloud not in join on
$loc_services = Clinic::select('*')
->join('locations', 'locations.clinicID', '=', 'clinics.clinicID')
->join('location_services', 'location_services.locationID', '=', 'locations.locationID')
->join('services', 'services.serviceID', '=', 'clinics.services_id')//service_id column in Clinic
->where('services.serviceID',$services_id)
->get();

Answer 2

The third parameter in join will be treated as column. If you want to join the column with a specific value, you can use closure like this:
$loc_services = Clinic::select('*')
->join('locations', 'locations.clinicID', '=', 'clinics.clinicID')
->join('location_services', 'location_services.locationID', '=', 'locations.locationID')
->join('services', function($join) use ($service_id) {
$join->where('services.serviceID', $service_id);
})
->get();
The Raw sql will be:
inner join `services` on `services`.`serviceID` = 10
