MDB File Upload Plugin works just like a regular input with type='file' You'll just need to add it to the form, allow the user submitting it to the server and handle it on the server-side. This is a code I've found for you and modified to include File Upload Plugin.

1. Create a form in your blade template with an input element of type file:

   <form action="{{ route('file.upload') }}" method="POST" enctype="multipart/form-data">
     @csrf
     <input
       type="file"
       id="input-file-now"
       class="file-upload-input"
       data-mdb-file-upload="file-upload"
       name='file'
     />
     <button type="submit">Upload</button>
   </form>
   

2. Create a route in your web.php file that maps to a controller method that handles the file upload:

   Route::post('/file/upload', 'FileController@upload')->name('file.upload');
   

3. Create a controller called FileController with a method called upload that will handle the file upload:

   <?php
   
   namespace App\Http\Controllers;
   
   use Illuminate\Http\Request;
   
   class FileController extends Controller
   {
   public function upload(Request $request)
   {
       // Validate the uploaded file
       $request->validate([
           'file' => 'required|file|mimes:pdf,doc,docx|max:2048'
       ]);
   
       // Get the uploaded file
       $file = $request->file('file');
   
       // Save the file to a storage location
       $file->store('public/uploads');
   
       // Return a response
       return response()->json(['message' => 'File uploaded successfully']);
   }
   }
