laravel 8 api : delete file from folder when updating post - php

Question

i have posts tables and i upload images for it , so in update() method in PostController() i want to edit post and images
for editing images , i want to delete last images from folder and database , and replace new images.
so i can delete last images from database but i can't delete them from folder
the controller :
public function update(StorePostRequest $request , $id )
{
$validatedData = $request->all();
if ($request->hasfile('image')) {
$postTitle = $request->title; //post title for folder name and the images inside it
//delete last Images from database for updating images
Image::where('imageable_type' , 'App\Models\Post')->where('imageable_id' , $id)->delete();
$directory =storage_path().'/images/posts/'.$postTitle;
if($directory){
Storage::disk('public')->deleteDirectory('images/posts/.$postTitle');
}
$files = $request->file('image');
foreach ($files as $file) {
$imageName = time().rand(1,10000).'.'.$file->extension();
$postTitle = $request->title; //post title for folder name and the images inside it
$imagePath = public_path(). '/images/posts/'.$postTitle;
$file->move($imagePath, $imageName);
$image = new Image;
$image->image = $imageName;
$image->path = $imagePath;
$images[] = $image; // make an array of uploaded images
}
}
$post = Post::find($id);
$post->category_id = $validatedData['category_id'];
$post->title = $validatedData['title'];
$post->body = $validatedData['body'];
$post->study_time = $validatedData['study_time'];
$post->save();
$post->images()->saveMany($images);
return response()->json([
"success" => true,
"message" => "successfully",
"data" => $post
]);
}
the relation between posts and images is : one to many polymorphic and i taste it with postman
i tried this ways and it doesn't work :
File::delete(public_path('/images/posts/'.$postTitle));
Storage::disk('public')->deleteDirectory($directory);
in addition , when i try
Storage::disk('public')->deleteDirectory('images/posts/');
it works and the posts folder has been deleted , but the problem is from $postTitle
when i use it, doesn't work

Answer 1

you can use this code for delete file
if (!is_dir(public_path('/images/posts/'.$postTitle))) {
mkdir(public_path('/images/posts/'.$postTitle));
}

Answer 2

If you need to delete directory use Storage::disk('public')->deleteDirectory('images/posts');
