How to pass id to controller in laravel 5.2 - laravel

Question

I using this method to upload the image and passing the page id so i can store the path into database but having error "Missing argument 2 for App\Http\Controllers\RoundtablesController::postImage()"
This is my form
<div class="btn-group">
{!! Form::open(array('action' => 'RoundtablesController#postImage',$tables->id, 'files'=>true)) !!}
<div class="form-group">
{!! Form::label('Profile-Picture', 'Profile Picture:') !!}
{!! Form::file('profile_image',null,['class'=>'form-control']) !!}
</div>
<div class="form-group">
{!! Form::submit('Save', ['class' => 'btn btn-primary form-control']) !!}
</div>
{!! Form::close() !!}
</div>
This is my route
Route::post('/roundtables/settings',['uses'=>'RoundtablesController#postImage','middleware'=>['auth']]);
This is my controller ,the $name should get the Page Id, but look like the id not passed to here yet
public function postImage(Request $request,$name){
$table_details =Detail::find($name);
//save image
if ($request->hasFile('profile_image')) {
//add new photo
$image = $request->file('profile_image');
$filename = time() . '.' . $image->getClientOriginalExtension();
$location = public_path('images/' . $filename);
Image::make($image)->resize(800, 400)->save($location);
$oldFilename = $table_details->profile_image;
//update database
$table_details->profile_image = $filename;
//Delete old image
Storage::delete($oldFilename);
}
$table_details->update();
Can i know where is the error? Sry i know this is very basic but i am new in laravel.

Answer 1

Route:
Route::post('/roundtables/settings/{id}',
['as' => 'roundtables.setting',
'middleware'=>['auth'],
'uses'=>'RoundtablesController#postImage']);
Action:
public function postImage(Request $request, $id) {
$Detail = Detail::findOrFail($id); // will return 404 or exception if record not found
if ($request->hasFile('profile_image')) {
$file = $request->file('profile_image');
$profile_image = time() . '.' . $file->getClientOriginalExtension();
$profile_image_file = public_path('images/' . $profile_image);
Image::make($image)
->resize(800, 400)
->save($profile_image_file);
$old_profile_image_file = public_path('images/'.$Detail->profile_image);
if(is_file($profile_image_file)) { // if new file successfully created
$Detail->profile_image = $profile_image; // changing profile_image
$Detail->save(); // saving
Storage::delete($old_profile_image_file);
}
}
}
in view open form like (use named route: roundtables.setting defined in router):
{!! Form::open(array('url' => route('roundtables.setting', $tables->id), 'files'=>true)) !!}
also it's a little bit strange $tables->id, are You sure that $tables is an instance of model (not an array or collection) ?

Answer 2

route should be like
Route::post('/roundtables/settings/{name}',['uses'=>'RoundtablesController#postImage','middleware'=>['auth']]);

Answer 3

Try this way...
Route::get('groups/(:any)', array('as' => 'group', 'uses' => 'groups#show'));
class Groups_Controller extends Base_Controller {
public $restful = true;
public function get_show($groupID) {
return 'I am group id ' . $groupID;
}
}
