Edit Image of Post With ploymorphic relation - php

Question

Hy all,
I need to update the picture of a article, all it's fine for updating post but my question it's how to update the image of this post with my polymorphic relation.
i have a table Images with imageable_id imageable_type path .
in my Post controller update function i have
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('posts/'.Input::get('id').'/edit')->withInput()
->withErrors($validation)
->with('alert_error','Veuillez corriger les érreurs SVP');
}
if(Input::hasFile('mediafile')){
$file = Input::file('mediafile');
$name = date('Ymd') . '-' . $file->getClientOriginalName();
$file = $file->move('img/uploads/', $name);
$path = $file->getRealPath();
//take the path only at the img not totally
$pos = strpos($path,'/img/');
if ($pos !== false) {
$path = substr($path, $pos + 1);
}
$input['file'] = $path;
$post=Post::find(Input::get('id'));
$post->name = e(Input::get('name'));
$post->description = e(Input::get('description'));
$post->category_id = e(Input::get('categories'));
$post->tag_id = e(Input::get('tag'));
$post->rating = e(Input::get('rating'));
$post->content = Input::get('content');
$post->is_online = e(Input::get('online'));
$post->images->path = e(Input::get('mediafile'));
$post->save();
}
}
My model Post
public function images(){
return $this->morphMany('Image','imageable');
}
So i wish update only the path of my image in my table Image when i submit my form to show the new picture of post.
Thank's for help

Answer 1

The morphMany will return a collection of Images, so when you run $post->images->path you're setting the path attribute on the collection not on an image model. If a Post is only meant to have one image, change it to a morphOne or alternatively you will have to identify the image model you wish to update from the collection.
