With or without whereHas, two queries will be run. One to select all users another one to load the related models. When you add the whereHas condition a subquery is added, but it's still two queries.

However, syntactically you could optimize this a bit by adding a query scope to your model (or even a base model if you want to use this more often):

public function scopeWithAndWhereHas($query, $relation, $constraint){
return $query->whereHas($relation, $constraint)
->with([$relation => $constraint]);


User::withAndWhereHas('submissions', function($query) use ($id){
$query->where('taskid', $id);

If you don’t want to add a scope, like above you can do something like this as well

$callback = function($query) {
$query->where('something', '=', 'something');
$submissions = Post::whereHas('submissions', $callback)->with(['submissions' => $callback])->get();

Form inputs along with multiple image upload using Dropzone

Today I had to upload multiple images as a field along with other inputs. Most of the tutorials found online have the implementation of dropzone as the only item in the form. But I needed to implement dropzone with an existing form.

For brevity, I have included two input fields and a dropzone.

Frontend Code:

Frontend Implementation of form with dropzone

Backend implementation:

// packagesController@store
public function
store(Request $request)
$input = $request->all();

$package = Package::create($input);
foreach($request->file as $photo){
$filename = $photo->storeAs('public/uploads/packages/' . $package->id, $photo->getClientOriginalName());
$package->images()->create(['name' => $filename]);


If the form has validation error, you need to remove images and add them again.

You need to append request (as array) in the result before printing the pagination links


$result is search result.

You can also filter out things you don’t want to send:

{{$result->appends(request()->except(['page', '_token']))->links()}}

Here are simple solutions to the errors thrown by laravel.

  • In project folder, you should have .env file. If you don’t rename .env.example to .env and run artisan key:generate command.
mv .env.example .envphp artisan key:generate
  • Also check if you have autoload.php in vendor folder
composer install


composer update
  • provide write access to storage folder.
chmod -R 775 storage
