Eloquent join table with two conditions - php

Question

I have two tables:
A: id | user_id | phonenumber | status | ...
B: id | user_id | phonenumber | name | ...
I would like to list all elements in table A but I have to left join the elements to table B.
I can do it with DB:
DB::table('A')
->leftJoin('B', function ($join) {
$join->on('A.phonenumber', '=', 'B.phonenumber')
->on('A.user_id', '=', 'B.user_id');
})
->select(...)
->where('A.user_id', '=', $userId)
->get();
Is it possible to solve it with eloquent somehow?

Answer 1

You can use eloquent, one way is to change it to
A::leftJoin('B', function ($join) {
$join->on('A.phonenumber', '=', 'B.phonenumber')
->on('A.user_id', '=', 'B.user_id');
})
->select(...)
->where('A.user_id', '=', $userId)
->get();
And with using pure eloquent
You would have to do adjustment to your A model. We would define two model functions.
public function phoneNumber()
{
return $this->hasMany(B::class, "phonenumber", "phonenumber");
}
public function userId()
{
return $this->hasMany(B::class, "user_id", "user_id");
}
Now we will change our query to
A::with("phonenumber")->has("phonenumber")
->with("userId")->has("userId")
->where("user_id","=",$userId)
->get();
This should work for you.
** Updated ***
if you want all the record in A then simply do
A::with("phonenumber","userId")
->where("user_id","=",$userId)
->get();

Answer 2

modelname::where(condition)->leftjoin(tablename,fieldname,othertable.fieldname)->get()
This is format how we write join in laravel
$postdata = post::select('categories.id', 'posts.id', 'categories.categoryname', 'posts.title', 'posts.body', 'posts.image', 'posts.created_at', 'users.name')
->where('post_type', 'publish')
->where('status', 'active')
->where('categories.id', $id)
->leftJoin('users', 'users.id', '=', 'posts.user_id')
->leftJoin('categories', 'categories.id', '=', 'posts.category')
->orderBy('created_at', 'desc')
->paginate(5);
This query display blog with username and with category using join it's my proect convenient query you can also create for you in this manner
