album-photo laravel gallery. error on updating photos in an album - php

Question

i have been trying to update photos in an album but i cant get it right. i know that i need to get the album id of the photos that i want to update but i cannot get the right logic for the request.
this is the error am getting whenever i request for an update
SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'album_id' cannot be null (SQL: update `photos` set `album_id` = , `photo` = IMG-20190527-WA0001_1570703623.jpg, `size` = 275807, `updated_at` = 2019-10-10 10:33:44 where `id` = 197)
the photos model for the application is as shown below
class Photos extends Model
{
protected $fillable = array('album_id', 'description', 'photo', 'title', 'size');
public function album(){
return $this->belongsTo('App\Album');
}
}
this is what i have tried for the update logic in the photosController. i have tried to request for the album id but it does not seem to work
public function edit($id){
$photo = Photos::find($id);
return view('photos/edit')->with('photo', $photo);
}
public function update(Request $request, $id){
$this->validate($request, [
'photo' => 'required | max:15000'
]);
$path = [];
//get filename with extension
$filenameWithExt = $request->file('photo')->getClientOriginalName();
//get just filename
$filename = pathinfo($filenameWithExt, PATHINFO_FILENAME);
//get extension
$extension = $request->file('photo')->getClientOriginalExtension();
//create new file name
$filenameToStore = $filename.'_'.time().'.'.$extension;
//get file size
$filesize = $request->file('photo')->getClientSize();
$path = $request->file('photo')->storeAs('public/photos'.$request->input('album_id'), $filenameToStore);
$photo = Photos::find($id);
$photo->album_id = $request->input('album_id');
$photo->size = $filesize;
$photo->photo = $filenameToStore;
$photo->save();
return $path;
}
each time i return the path for the photo am updating there is no id for the photo. only happens when i omit the save method
public/photos//IMG-20190527-WA0001_1570706571.jpg
photo edit php view code
{!!Form::open(['action' => ['PhotosController#update', $photo->id], 'method' => 'POST', 'enctype' => 'multipart/form-data'])!!}
{{Form::file('photo')}}
{{Form::hidden('_method','PUT')}}
{{Form::submit('submit')}}
{!! Form::close() !!}
database model for photos table
public function up()
{
Schema::create('photos', function (Blueprint $table) {
$table->increments('id');
$table->integer('album_id');
$table->string('photo');
$table->string('size');
$table->timestamps();
});
}
public function down()
{
Schema::dropIfExists('photos');
}
help would be appreciated

Answer 1

The error is at this line
$photo->album_id = $request->input('album_id');
You don't have an input in your form with the name album_id
You can either create a hidden one and assign it the value
{!!Form::open(['action' => ['PhotosController#update', $photo->id], 'method' => 'POST', 'enctype' => 'multipart/form-data'])!!}
{{Form::file('photo')}}
{{Form::hidden('_method','PUT')}}
{{-- Here --}}
{{Form::hidden('album_id', $photo->album->id)}}
{{Form::submit('submit')}}
{!! Form::close() !!}
or get it from the relationship like so
$photo->album_id = $photo->album->id;
Note that you're also using that null|empty value here
$path = $request->file('photo')
->storeAs('public/photos'.$request->input('album_id'), $filenameToStore);
So make sure to update that too
Hope this helps
