search with pagination is not working in laravel - php

Question

I make it in 1 route with
in route
Route::get('/all-students', 'AdminController#studentList')->name('admin.student');
Route::post('/all-students', 'AdminController#searchByClassRoll')->name('search-by-class-roll');
in controller funtion student list
public function studentList(Request $request)
{
Session::put('url.intended2', URL::current());
Session::put('url.intended', URL::previous());
if (isset($request->class)) {
if (isset($request->roll)) {
if ($request->class == 'all') {
$students = DB::table('students')
->where('roll', '=', $request->roll)
->orderBy('id', 'DESC')
->paginate(20);
} else {
$students = DB::table('students')
->where('roll', '=', $request->roll)
->where('class', '=', $request->class)
->orderBy('id', 'DESC')
->paginate(20);
}
} else {
if ($request->class == 'all') {
return redirect()->route('admin.student');
} else {
$students = DB::table('students')
->where('class', '=', $request->class)
->orderBy('id', 'DESC')
->paginate(20);
}
}
} else {
$students = DB::table('students')
->orderBy('id', 'DESC')
->paginate(20);
}
return view('admin.student-list')->with('students', $students);
}
post method
public function searchByClassRoll(Request $request)
{
$class = $request->class;
$roll = $request->roll;
if (isset($request->class)) {
if (isset($request->roll)) {
return redirect()->route('admin.student', ['class' => $class, 'roll' => $roll]);
} else {
return redirect()->route('admin.student', ['class' => $class]);
}
}
}
in blade
#if(method_exists($students,'links'))
{!! $students->links() !!}
#endif
normally when I click page 2 it returns
all-students?page=2
when I search something all-students?class=2 and then i click on pagination page it returns again all-students?page=2 and remove the search data from URL.
form from view
<form action="{{ route('search-by-class-roll') }}" method="post">
{{ csrf_field() }}
<input type="hidden" name="type" value="student_list">
<div class="row gutters-8">
<div class="col-4-xxxl col-xl-4 col-lg-3 col-12 form-group">
<div class="ui-alart-box">
<div class="default-alart">
<div class="result" role="alert">
#if(app('request')->input('class') || app('request')->input('roll'))
See All<span> | </span>
#endif
Showing results {{$students->count()}} of {{$students->total()}} entries
</div>
</div>
</div>
</div>
<div class="col-3-xxxl col-xl-3 col-lg-3 col-12 form-group">
<input type="number" name="roll" placeholder="Search by Roll..." class="form-control">
</div>
<div class="col-4-xxxl col-xl-3 col-lg-3 col-12 form-group">
<select class="select2 form-control" name="class" required>
<option value="all">All Classes</option>
<option value="baby">baby</option>
<option value="nursery">nursery</option>
<option value="1">one</option>
<option value="2">two</option>
<option value="3">three</option>
<option value="4">four</option>
<option value="5">five</option>
<option value="6">six</option>
<option value="7">seven</option>
<option value="8">eight</option>
<option value="9">nine</option>
<option value="10">ten</option>
</select>
</div>
<div class="col-1-xxxl col-xl-2 col-lg-3 col-12 form-group">
<button type="submit" class="fw-btn-fill btn-gradient-yellow">SEARCH</button>
</div>
</div>
</form>
i want to made this because I want this in 1 URL just because if someone manually entered the URL with search data he can see the output. but in here I can't get the result with pagination from blade. when I turned into page 2 it remove the search variable from URL. and paginate the whole data. how can I get result with pagination after search?

Answer 1

There is the simpler way
Just add with your paginated array.
{{ $users->withQueryString()->links() }}

Answer 2

Coming directly to your controller. You don't need any other route or method you can handle this filtering on same route and in same method.
public function studentList(Request $request)
{
if(!empty($request)){
$query = $request->all();
$students = DB::table('students')->orderBy('id', 'DESC');
if(isset($request->class) AND $request->class != '' AND $request->class != 'all')
$students = $students->where('class', '=', $request->class);
if(isset($request->roll) AND $request->roll != '')
$students = $students->where('roll', '=', $request->roll);
$students = $students->paginate(20);
return view('admin.student-list', compact('students','query'));
}
$students = DB::table('students')
->orderBy('id', 'DESC')
->paginate(20);
return view('admin.student-list', compact('students'));
}
Change few things in your view
<form action="{{ route('admin.student') }}" method="get"> change route and method to get
{{ csrf_field() }} //remove this
Below your table inside view write this code. The appends() is most important otherwise pagination in your filtered data won't work.
#if(isset($query))
{{ $students->appends($query)->links() }}
#else
{{ $students->links() }}
#endif

Answer 3

Try use append on paginator blade
{{$students->appends(\Illuminate\Support\Facades\Input::except('page'))->links()}}
