Laravel - How to use a single textbox for global search - laravel

Question

I have this Laravel-5.8 code whereby users can search using different control fields to search for employee_code, designation and department.
class HrEmployee extends Model
{
protected $table = 'hr_employees';
protected $primaryKey = 'id';
protected $fillable = [
'id',
'employee_code',
'address',
'email',
'employee_designation_id',
'first_name',
'emp_image',
'last_name',
'other_name',
'department_id',
];
protected $appends = ['full_name'];
public function user()
{
return $this->belongsTo('App\User');
}
public function designation()
{
return $this->belongsTo('App\Models\Hr\HrDesignation','employee_designation_id');
}
public function department()
{
return $this->belongsTo('App\Models\Hr\HrDepartment','department_id');
}
}
Controller
public function index(Request $request)
{
$userCompany = Auth::user()->company_id;
$render=[];
$employees = HrEmployee::where('company_id', $userCompany);
$employees=$employees->with('department','designation');
if(isset($request->employee_code))
{
$employees=$employees->where('employee_code','like','%'.$request->employee_code.'%');
$render['employee_code']=$request->employee_code;
}
if(isset($request->employee_designation_id))
{
$employees=$employees->where('employee_designation_id',$request->employee_designation_id);
$render['employee_designation_id']=$request->employee_designation_id;
}
if(isset($request->department_id))
{
$employees=$employees->where('department_id',$request->department_id);
$render['department_id']=$request->department_id;
}
$employees= $employees->paginate(6);
$employees= $employees->appends($render);
$data['employees'] = $employees;
$data['departments']= HrDepartment::where('company_id', $userCompany)->pluck('dept_name','id');
$data['designations']= HrDesignation::where('company_id', $userCompany)->pluck('designation_name','id');
return view('hr.employees.index',$data);
}

Instead of searching for each field one by one using different control fields. How do I use a sing textbox to search for employee_code, first_name, last_name, department and designation?
Thank you

Answer 1

You can do it with below code:
$searchText = $request->searchText;
$employees = HrEmployee::with(['department','designation'])->where('company_id', $userCompany);
if($searchText)
{
$employees->where(function ($query) use($searchText) {
$query->where('employee_code','like','%'.$searchText.'%')
->orWhere('first_name','like','%'.$searchText.'%')
->orWhere('last_name','like','%'.$searchText.'%')
->orWhereHas('designation', function($q) use ($searchText) {
$q->where('designation_name', 'like','%'.$searchText.'%');
})
->orWhereHas('department', function($q) use ($searchText) {
$q->where('department_name', 'like','%'.$searchText.'%');
});
});
}
$employees = $employees->get();
// For pagination
// $employees = $employees->paginate(6);
Here designation_name is name field in designation table and department_name is name field in designation table.

Answer 2

{{ Form::model(request(),['method'=>'get']) }}
<div class="row" style="margin-bottom: 10px">
<div orm-group class="col-sm-3">
{{Form::label('search', 'Search')}}
{{ Form::text('search',null,['class'=>'form-control','placeholder'=>'search']) }}
</div>
<div class="col-xs-3">
<br>
{{ Form::submit('Search',['class'=>'btn btn-warning']) }}
</div>
{{ Form::close() }}
then your controller function use orwhere()
public function index(Request $request)
{
$search = $request->search;
$userCompany = Auth::user()->company_id;
$render=[];
$employees = HrEmployee::where('company_id', $userCompany);
$employees=$employees->with('department','designation');
$employees=$employees->where('employee_code','like','%'.$search.'%')
->orWhere('employee_designation_id',$search)
->orwhere('department_id',$search)
->paginate(6);
$data['employees'] = $employees;
$data['search'] = $search;
$data['departments']= HrDepartment::where('company_id', $userCompany)->pluck('dept_name','id');
$data['designations']= HrDesignation::where('company_id', $userCompany)->pluck('designation_name','id');
return view('hr.employees.index',$data);
}
