How to edit image in Laravel 5.7? - php

Question

I inserted the image in my database, now I am trying to edit the images and the edited image should be deleted from my folder and a new image should be updated there. Could you please help me where I am mistaking?
Here is my Controller.php file
public function edit($slider)
{
$property=Property::all();
$slider = Slider::find($slider);
$data = ['property'=>$property, 'slider'=>$slider];
return view('admin.slider.edit', $data);
}
public function update(Request $r, $id)
{
$slider=Slider::find($id);
if( $r->hasFile('slider_thumb')){
$thums = $r->slider_thumb;
$slider_thumb = uniqid($chr).'.'.$thums->getClientOriginalExtension();
$img = Image::make($thums->getRealPath());
$img->resize(204, 107, function ($constraint) {
$constraint->aspectRatio();
});
$thumbPath = public_path().'/slider_img/'.$slider_thumb;
if (file_exists($thumbPath)) {
$this->removeImage($thumbPath);
}
$img->save($thumbPath);
$optimizerChain = OptimizerChainFactory::create();
$optimizerChain->optimize($thumbPath);
$slider_thumbimg = $slider_thumb;
}else{
$slider_thumb = NULL;
}
$slider->property_id = $r->property_id;
$slider->slider_image=$slider_imageimg;
$slider->save();
return redirect('/admin/slider');
}
}
here is my HTML file
<form class="form-horizontal" method="POST" action="{{ route('slider.update',['id'=>$slider->id]) }}" enctype="multipart/form-data">
#csrf
#method('PUT')
#if($slider->slider_image == NULL or $slider->slider_image == '')
<img src="{{asset('images/no-image-found.jpg')}}" style="width: 100px; height: 100px;">
#else
<img src="{{ asset('slider_img/'.$slider->slider_image) }}" style="width: 100px; height: 80px;">
#endif
<input type="file" name="slider_image" value="{{ $slider->slider_image }}">
<div class="form-group">
<div class="col-sm-12 text-right">
<button type="submit" class="btn btn-info">
<i class="fa fa-check"></i> Save
</button>
</div>
</div>
</form>

You did not use Laravel standards. you need to refer to laravel filesystem document to upload file. then you need to check request file exist. if request has new file; you should remove old file and upload new file. in else you should not remove old file.
follow below code:
public function store(PostRequest $request,string $slug = null)
{
$postData = $request->all();
//upload and set thumbnail of post, if exist
if($request->file("thumbnail")){
$image = new Images();
$thumbnailName = $image->uploadFile($request,"thumbnail",config("upload_image_path.post-thumbnail"));
$postData["thumbnail"] = $thumbnailName;
}
$post = $this->postService->save($postData,$slug);
