i'm creating a form to update my project but i get this error Creating default object from empty value
Here is my route :
Route::get('admin/projects/edit/{id}','ProjectsController#edit');
Route::put('admin/projects/update/{id}','ProjectsController#update');
The edit view :
#extends ('layout.admin')
#section ('content')
{{ Form::open(array('url'=>'admin/projects/update/'.$project->id.'','enctype'=>'multipart/form-data','method'=>'put','style'=>'margin:0!important;')) }}
{{ Form::token() }}
<div class="form-group">
{{ Form::label('name','Nom :') }}
{{ Form::text('name',$project->name,array('class'=>'form-control')) }}
#if($errors->first('name'))
<div class="alert alert-danger" role="alert">{{ $errors->first('name') }}</div>
#endif
</div>
<div class="form-group">
{{ Form::label('slug','Slug :') }}
{{ Form::text('slug',$project->slug,array('class'=>'form-control')) }}
#if($errors->first('slug'))
<div class="alert alert-danger" role="alert">{{ $errors->first('slug') }}</div>
#endif
</div>
<div class="form-group">
{{ Form::label('category_id','Category :') }}
{{ Form::select('category_id',$cats,$project->category_id) }}
</div>
<div class="form-group">
{{ Form::label('thumbnail','Image :') }}
{{ Form::file('thumbnail',array('class'=>'form-control')) }}
#if($errors->first('thumbnail'))
<div class="alert alert-danger" role="alert">{{ $errors->first('thumbnail') }}</div>
#endif
</div>
<div class="form-group">
{{ Form::label('description','Description :') }}
{{ Form::textarea('description',$project->description,array('class'=>'form-control')) }}
#if($errors->first('description'))
<div class="alert alert-danger" role="alert">{{ $errors->first('description') }}</div>
#endif
</div>
{{ Form::submit('Modifier', array('class'=>'btn btn-primary','style'=>'float:left')) }}
{{ Form::close() }}
<button class="btn btn-danger" style="float:left;margin-left:20px;">Supprimer</button>
#stop
And my controller
public function update($id){
$inputs = Input::all();
$rules = array(
'name'=>'required|min:5',
'description'=>'required|min:10'
);
$validation = Validator::make($inputs,$rules);
if($validation->fails()){
return Redirect::to('admin/projects/edit/'.Input::get('id').'')->withInput()->withError();
}
$project=Project::find($id);
$project->name = Input::get('name');
$project->slug = Slug::create(Input::get('slug'));
$project->category_id = Input::get('category_id');
$project->description = Input::get('description');
if(Input::hasFile('thumbnail')){
$img = Str::slug(Input::get('name').'png');
$post->thumbnail = 'img/'.$img.'';
}
if(Input::hasFile('thumbnail')){
Input::file('thumbnail')->move('img/',$img);
}
return Redirect::to('admin/projects')->with('Alert_succes','Votre projet a bien été mis à jour');
}
public function edit($id)
{
$project = Project::find($id);
$categories = Category::all();
$cats = array();
foreach ($categories as $category){
$cats[$category->id] = $category->name;
}
return View::make('projects.edit')->with(array('project'=>$project,'cats'=>$cats));
}
I Dont really understand where the errors is , the problem come from this line according to laravel debuger : $post->thumbnail = 'img/'.$img.'';
Thank You for your help

Answer 1

You are using $post->thumbnail = 'img/'.$img.''; but you didn't create a $post object. Instead you have $project object from this code:
$project = Project::find($id);
Where is $post in your code ? It should be $project and also make sure if you got an object, using something like this:
$project = Project::find($id);
if($project) {
//...
}
It looks that, $post->thumbnail should be $project->thumbnail in your update method.
