Need help in Laravel Eloquent for Multiple Join - laravel

Question

I have 3 tables. Events, Events_join , Customers . in event_join I have only customer id those who join the event. currently, I fetching events with an array of events_join using this
my DB structure is:
Table structure for table my_events
CREATE TABLE IF NOT EXISTS `my_events` (
`id` int(10) unsigned NOT NULL,
`userid` int(11) NOT NULL,
`title` varchar(255) COLLATE utf8_unicode_ci NOT NULL DEFAULT '',
`sdes` varchar(256) COLLATE utf8_unicode_ci NOT NULL DEFAULT '',
`pic` varchar(100) COLLATE utf8_unicode_ci NOT NULL DEFAULT '1',
`sdate` date NOT NULL DEFAULT '1970-01-01',
`edate` date NOT NULL DEFAULT '1970-01-01',
`country` int(11) NOT NULL,
`city` int(11) NOT NULL,
`location` varchar(256) COLLATE utf8_unicode_ci NOT NULL,
`url` varchar(256) COLLATE utf8_unicode_ci NOT NULL,
`des` varchar(10000) COLLATE utf8_unicode_ci NOT NULL DEFAULT '',
`cat` int(10) unsigned NOT NULL DEFAULT '1',
`deleted_at` timestamp NULL DEFAULT NULL,
`created_at` timestamp NULL DEFAULT NULL,
`updated_at` timestamp NULL DEFAULT NULL,
`timezone` varchar(90) COLLATE utf8_unicode_ci NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
Table structure for table customers
CREATE TABLE IF NOT EXISTS `customers` (
`id` int(10) unsigned NOT NULL,
`title` varchar(10) COLLATE utf8_unicode_ci NOT NULL,
`firstname` varchar(50) COLLATE utf8_unicode_ci NOT NULL DEFAULT '',
`lastname` varchar(50) COLLATE utf8_unicode_ci NOT NULL,
`username` varchar(100) COLLATE utf8_unicode_ci NOT NULL DEFAULT '',
`email` varchar(255) COLLATE utf8_unicode_ci NOT NULL DEFAULT '',
`phone` varchar(40) COLLATE utf8_unicode_ci NOT NULL,
`country` int(10) unsigned NOT NULL DEFAULT '1',
`city` int(10) DEFAULT NULL,
`company` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
`password` varchar(255) COLLATE utf8_unicode_ci NOT NULL DEFAULT '',
`pic` varchar(100) COLLATE utf8_unicode_ci DEFAULT NULL,
`level` int(10) unsigned NOT NULL DEFAULT '1',
`status` tinyint(4) NOT NULL DEFAULT '1',
`deleted_at` timestamp NULL DEFAULT NULL,
`created_at` timestamp NULL DEFAULT CURRENT_TIMESTAMP,
`updated_at` timestamp NULL DEFAULT NULL
) ENGINE=InnoDB AUTO_INCREMENT=19 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
Table structure for table events_join
CREATE TABLE IF NOT EXISTS `events_join` (
`id` int(11) NOT NULL,
`userid` int(11) NOT NULL,
`eventid` int(11) NOT NULL,
`sdate` date NOT NULL,
`edate` date NOT NULL,
`date` datetime NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
My Events model have this
public function customers()
{
return $this->belongsToMany(Events::class,EventsJoin::class);
}
My Customer model have this
public function events()
{
return $this->belongsToMany(Customer::class,EventsJoin::class);
}
My EventsJoin have this Pivot
public function customer()
{
return $this->belongsTo(Customer::class);
}
public function event()
{
return $this->belongsTo(Events::class);
}
my eventControler have this
$events=Customer::with(['event']);
but its return empty record. the way its working is customers can create events and other customers will join the event. currently those join the events save with userid in events_join table. I want to join events_join table with the customers table so that I can get additional information of the customer.

While not mentioned in your code, I would have to guess that you have 3 Models, one Events, another one for EventsJoin and one for Customers.
What you seem to have, although you don't say it, is a Many to Many relationship in which a Customer can be in Multiple Events and an Event can be joined by Multiple customers.
In Laravel eloquent terms a Many for Many relationship is described with a belongsToMany.
Take a look at the documentation: https://laravel.com/docs/master/eloquent-relationships#many-to-many
Because it is a Many to Many relationship, the EventsJoin needs to extend Pivot and not Model.
So you would have in your Customer Model something like:
public function events()
{
return $this->belongsToMany(Customer::class,EventsJoin::class);
}
And in your EventsJoin Pivot model
public function customer()
{
return $this->belongsTo(Customer::class);
}
public function event()
{
return $this->belongsTo(Event::class);
}
And in your Events Model
public function customers()
{
return $this->belongsToMany(Event::class,EventsJoin::class);
}
When you wish to get the array of event objects you would do $customer->events;
And when you wish to get the array of customers from the event you would do $event->customers;
Do note that plural and singular cases are important for Laravel Eloquent.
