How can I hidden data in JSON if variable is empty - php

Question

I got a some trouble in my Laravel application, in Search function, when I do search the result is
{
"data": [
{
"id": 2,
"user_id": 8,
"identity_number": "213918273",
"name": "Pekerja_2",
"gender_id": 1,
"date_of_birth": "1999-05-25",
"address": "Jalan Bandung Raya no 50",
"province_id": 32,
"city_id": 3273,
"district_id": 3273160,
"phone": "4232343432",
"image": null,
"created_at": "2018-01-11 10:59:54",
"updated_at": "2018-01-11 10:59:54",
"partner_id": null,
"skill": [
{
"id": 3,
"worker_id": 2,
"skill_id": 6,
"sub_skill_id": 18,
"created_at": "2018-01-15 13:06:48",
"updated_at": "2018-01-15 13:06:48",
"price": null,
"unit": null
}
]
},
{
"id": 3,
"user_id": 16,
"identity_number": "213918273",
"name": "Pekerja_3",
"gender_id": 1,
"date_of_birth": "1999-05-25",
"address": "Jalan Bandung Raya no 50",
"province_id": 32,
"city_id": 3273,
"district_id": 3273160,
"phone": "2345234234",
"image": null,
"created_at": "2018-01-15 13:06:48",
"updated_at": "2018-01-15 13:06:48",
"partner_id": null,
"skill": []
}
]
}
as you can see that "Skill" with id number 3 is empty, I want all in id number 3 is empty also.
My controller is :
$worker = Worker::with(['skill' => function($q) use ($request) {
$q->where('worker_skills.sub_skill_id', $request['sub_skill_id']);
}])->whereHas('skill');
And I want something like this :
{
"data": [
{
"id": 2,
"user_id": 8,
"identity_number": "213918273",
"name": "Pekerja_2",
"gender_id": 1,
"date_of_birth": "1999-05-25",
"address": "Jalan Bandung Raya no 50",
"province_id": 32,
"city_id": 3273,
"district_id": 3273160,
"phone": "2534234234",
"image": null,
"created_at": "2018-01-11 10:59:54",
"updated_at": "2018-01-11 10:59:54",
"partner_id": null,
"skill": [
{
"id": 3,
"worker_id": 2,
"skill_id": 6,
"sub_skill_id": 18,
"created_at": "2018-01-15 13:06:48",
"updated_at": "2018-01-15 13:06:48",
"price": null,
"unit": null
}
]
},
]
}
The point is, if "skill" variable is empty then data not show and vice versa.
Thankyou any help will appreciate, sorry for bad english

Answer 1

You can add a callback to your whereHas function with the same filter as the with function
$worker = Worker::with(['skill' => function($q) use ($request) {
$q->where('worker_skills.sub_skill_id', $request['sub_skill_id']);
}])
->whereHas('skill', function($q) use ($request) {
$q->where('worker_skills.sub_skill_id', $request['sub_skill_id']);
})
->get();

Answer 2

You can try this $worker = Worker:has('skill')->get();
Only worker that have at least one skill are contained in the collection
