Question

I`m new to laravel 5.4 .while um developing the function it gives error like this.
ReflectionException in RouteSignatureParameters.php line 39:
Method App\Http\Controllers\UserController::insertFile() does not exist
Here is my view called uploadfile.blade.php
{!! Form::open(array('url' =>'insertfile','method' =>'POST', 'class' =>'form-horizontal','files'=> true)) !!}
<h2>Upload your files </h2>
<form class="form-horizontal">
<div class="form-group">
<label for="name" class="col-sm-2 control-label">Title</label>
<div class="col-sm-10">
<input type="text" name="file_title" class="form-control file_title_c" id="file_title_id" placeholder="Enter Title">
</div>
</div>
<div class="form-group">
<label for="inputPassword3" class="col-sm-2 control-label">Upload</label>
<div class="col-sm-10">
<input type="file" name="filenam" class="filename">
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<button type="submit" class="btn btn-default">Submit</button>
</div>
</div>
{!!Form::close() !!}
Here is my developing controller UploadController
public function index(){
return view('upload/uploadfile');
}
public function insertFile(){
$filetitle=Input::get('file_title');
$file=Input::file('filenam');
echo $filetitle;
echo $file;
}
Here is the route
Route::get('upload', 'UploadController#index');
Route::post('insertfile', array('as'=>'insertfile','uses'=>'UserController#insertFile'));

Answer 1

Route::get('upload', 'UploadController#index');
Route::post('insertfile', array('as'=>'insertfile','uses'=>'UserController#insertFile'));
The answer is in your routes.
The error message is very explicit when it says:
ReflectionException in RouteSignatureParameters.php line 39: Method App\Http\Controllers\UserController::insertFile() does not exist
Notice 'UserController'... in your route you have: 'uses'=>'UserController#insertFile'
You should switch your route to:
Route::post('insertfile', array('as'=>'insertfile','uses'=>'UploadController#insertFile'));
Notice the change to:
'uses'=>'UploadController#insertFile'
