How to update image file in laravel? - laravel

Question

I am trying to update an image of a database (One-To-Many and Belongs-To Relationships)
i have table proposition with fields id, proposition.
now the proposition table has relations with image table like this
image module
public function proposition()
{
return $this->belongsTo('App\Proposition');
}
proposition module
public function propositionimage() {
return $this->hasMany('App\PropositionImages');
}
now i want to update the image to an proposition:
i want to get the old value of input file and change it with the new value of input file .
the probleme is whene i use this
$proposition = Proposition::find($num_proposition);
$image = $proposition->propositionimage()->get();
it showing all the image of the proposition
i want to update all the image but one by one , any help plz ?
the HTML code
<img src="/images/{{ $propositonimage->imagename }}" alt="">
<div class="caption">
<input type="file" name="image" value="{{$propositonimage->imagename}}" >
</div>
the update function
public function update(PropositionRequest $request, $num_proposition)
{
$proposition = Proposition::find($num_proposition);
$image = $proposition->propositionimage()->get();
// echo "$image";
$images = Input::file('image');
if (Input::hasfile('image')) {
$rules2 = array('image' => 'mimes:jpeg,bmp,png');
$validator2 = Validator::make($images, $rules2);
if ($validator2->passes()) {
$distinationPath = 'images';
$imagename = $images->getClientOriginalName();
$upload_success = $images->move($distinationPath, $imagename);
$extension = $images->getClientOriginalExtension();
}
}

Im not 100% sure what the problem is. But it seems as you want to iterate the collection over the div?
proposition model
public function propositionimage()
{
return $this->hasMany(PropositionImages::class);
}
image model
public function proposition()
{
return $this->belongsTo(Proposition::class);
}
Then you return a view with proposition in a controller, and eager load PropositionImages?
public function index(){
$propositions = \Proposition::with('propositionimage')->get();
return view('image', compact('propositions'));
}
You will have a collection of proposition with corresponding images.
#forelse ($propositions as $propositon)
<img src="/images/{{ $propositon->imagename }}" alt="">
#if($propositon->propositionimage->count())
<div class="caption">
#foreach($propositon->propositionimage as $propositionimage)
name: {{$propositionimage->imagename}}<br>
<input type="file" name="image" value="{{$propositionimage->imagename}}" >
#endforeach
</div>
#else
No proposition image <br>
#endif
#empty
No images :(
#endforelse
Please add more details to your question otherwise.
Edit
I tried this at my local dev machine and it works.
All relations of propositionimage will be iterated to the corresponding proposition.
