issues with Laravel9 Search form-CodePudding

I am trying to add a search form to my application. I thought I had everything right, but Laravel keeps on telling undefined $users in the view.

The Form Below

          <form action="{{URL::to('/students')}}" method="post">
                     @csrf
                     <div >
                        <div >
                            <input type="search" name="search" value="{{old('search')}}"  placeholder="Enter Search Term">
                            <div >
                               <input type="submit"  value="Search Students">
                            </div>
                        </div>
                        <div >
                            <span >@error('search'){{$message}}@enderror</span>
                        </div>
                     </div>
                    </form>

UsersController

public function search(Request $request){
        $request->validate([
         'search' => 'required',
        ]);

        $query = Students::SELECT('*')
            ->where('name','LIKE','%'.$request->search.'%')
            ->orWhere('email','LIKE','%'.$request->search.'%')
            ->orWhere('department','LIKE','%'.$request->search.'%')
            ->orWhere('course','LIKE','%'.$request->search.'%')
            ->get();
            return view('students',['users' => $query]);
     }

Routes

Route::get('/students',function(){
  return view('students');
}

Route::post('/students',[UsersController::class,'search']);

Inside Students View at views/students.blade.php

<table >
            <thead>
                <tr>
                    <th>Student ID</th>
                    <th>Stdent Name</th>
                    <th>Student Email</th>
                    <th>Student Department</th>
                    <th>Student Course</th>
                    <th>Actions</th>
                </tr>
            </thead>
            <tbody>
                @foreach ($users as $user)
                    <tr>
                        <td>{{$user->id}}</td>
                        <td>{{$user->name}}</td>
                        <td>{{$user->email}}</td>
                        <td>{{$user->department}}</td>
                        <td>{{$user->course}}</td>
                        <td>
            </tr>
       </tbody>
   </table>

It tells me that $users undefined

Can somebody help me solve this issue?

CodePudding user response：

Route::get('/students',[UsersController::class,'view']);

you're existing get route is literally only returning a view and nothing else so of course $users isn't defined

CodePudding user response：

This is how I did it.

public function search(Request $request){
   $query = Students::where('name','LIKE','%'.$request->search.'%')->get();
   return view('index',['students' => $query]);
}

in the Route

use App\Http\Controllers\StudentController;

Route::get('/',function(){
  return view('welcome');
});

Route::get('/'[StudentController::class,'search']);
``
in view at view/welcome.blade.php

It tells me that $students is undefined. How do I pass the variable in the route?

@foreach($students as $student)
   {{$tudent->id}}
   {{$student->name}}
   {{$student->email}}
@endforeach
