Eloquent filtering with multiple parameters - sql

Question

I am writing a search functionality which basically looks up several tables.
The DB structure and relationships are as follows:
`users`
id
name
user_type_id
`user_type`
id
type
`user_nicknames`
id
user_id
nickname
User model has a \Illuminate\Database\Eloquent\Relations\BelongsTo relationship with user_type
and a \Illuminate\Database\Eloquent\Relations\HasMany relationship to user_nicknames
What I am trying to get is search against a specific searchTerm which can be found either in users table and in user_nicknames
This one is failing right now:
$user = $this->user->newQuery();
$user->whereHas('userType', function ($query) use ($filters) {
$query->where('type', $filters['type']);
});
$user->whereHas('userNickName', function ($query) use ($searchTerm) {
$query->where('custom_title', 'like', '%'.$nickname.'%');
});
Please take note that I'd prefer to use the eloquent relationships for this rather than multiple joins.
Any ideas?

Answer 1

In your User model add these functions:
public function scopeUserTypeFilter($query, $filters)
{
return $query->whereHas('user_type', function ($query) use ($filters) {
$query->where('type', $filters['type']);
});
}
public function scopeNicknameFilter($query, $nickname)
{
return $query->whereHas('user_nick_name', function ($query) use ($searchTerm) {
$query->where('custom_title', 'like', '%'.$nickname.'%');
});
}
Then you can use these on your controller:
public function search(Request $reqeust)
{
$users = User::where(function ($query) use ($request) {
return $query->when($request->filled('s'), function($query) use ($request) {
return $query->nicknameFilter($request->s);
});
})->where(function ($query) use ($request) {
return $query->when($request->filled('userType'), function($query) use ($request){
return $query->userTypeFilter($request->userType);
});
})->get();
}
