Upload image file with specified name using laravel - ajax

Question

I want to store the image file with the id as a name .
So I tried the following code :
public function store(Request $request)
{
$validator = Validator::make($request->all(), [
'casting_photo' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',
]);
if ($validator->passes()) {
$request->casting_photo->storeAs(public_path('castingimages'),$request->Casting()->id.'.'.$request->casting_photo->extension() );
$data = ['casting_photo' =>$request->casting_photo];
Casting::create($data);
return response()->json(["status" => "success", "message" => "Success! post created."]);
}
return response()->json(["status" => "failed", "message" => "Alert! post not created"]);
}
But it gives me the 500 (Internal Server Error)
EDIT
if ($validator->passes()) {
$input['casting_photo'] = $request->Casting()->id .'.'.$request->casting_photo->extension();
$request->casting_photo->storeAs(public_path('castingimages'),$request->Casting()->id.'.'.$request->casting_photo->extension() );
$data = ['casting_name' => $request->casting_name,
'casting_cin' => $request->casting_cin,
'casting_email' => $request->casting_email,
'casting_phone' => $request->casting_phone,
'casting_age' => $request->casting_age,
'casting_sexe' => $request->casting_sexe,
'casting_city' => $request->casting_city,
'casting_address' => $request->casting_address,
'casting_photo'=> $input['casting_photo'] ];
Casting::create($data);
return response()->json(["status" => "success", "message" => "Success! post created."]);
}
return response()->json(["status" => "failed", "message" => "Alert! post not created"]);
I tried that and the same error occurs.
EDIT2
$fileName = $request->get('id') . '.' . $request->file('casting_photo')->extension();
$request->file('casting_photo')->storeAs('castingimages', $fileName);
But in databse I finf the image stored with just the extension like .png
EDIT3
<form id="castingform" method="post" action="castings" enctype="multipart/form-data">
{{ csrf_field() }}
<input type="hidden" name="id" />
<div class="form-group col-md-6">
<label for="casting_name">Nom</label>
<input type="text" class="form-control" id="casting_name" name="casting_name" placeholder="Nom" >
<span class="text-danger">{{ $errors->first('casting_name') }}</span>
</div>
<div class="input-group mb-3">
<div class="input-group-prepend">
<span class="input-group-text">Upload</span>
</div>
<div class="custom-file">
<input type="file" name="casting_photo" class="custom-file-input" id="casting_photo">
<div class="input-group-prepend">
<span class="text-danger">{{ $errors->first('casting_photo') }}</span>
</div>
<label class="custom-file-label" for="casting_photo">Choose file</label>
</div>
</div>
<button type="submit" id="createBtn" class="btn btn-success">Sign in</button>
</form>

Answer 1

You are accessing unknown id from request
$input['casting_photo'] = $request->Casting()->id .'.'.$request->casting_photo->extension();
it should be
$request->casting_photo->storeAs(public_path('castingimages'),$request->id.'.'.$request->casting_photo->extension() );
Updated
$request->casting_photo->storeAs(public_path('castingimages'),$request->Casting()->id.'.'.$request->casting_photo->extension() );
$data = ['casting_name' => $request->casting_name,
'casting_cin' => $request->casting_cin,
'casting_email' => $request->casting_email,
'casting_phone' => $request->casting_phone,
'casting_age' => $request->casting_age,
'casting_sexe' => $request->casting_sexe,
'casting_city' => $request->casting_city,
'casting_address' => $request->casting_address,
$casting=Casting::create($data);
$casting->casting_photo=$casting->id.'.'.$request->casting_photo->extension() );
$casting->save();
