public function postAddPost(Request $request) {
$post = $request->all();
$post = new Post;
$post->title = $request->title;
$post->author = $request->author;
$post->content = $request->content;
$post->intro = $request->intro;
$post->type = $request->type;
if($request->hasFile('image')) {
$file = $request->file('image');
$extension = $file->getClientOriginalExtension();
if($extension != 'jpg' && $extension != 'png' && $extension != 'jpeg') {
return back()->with('Error', 'File extension must be jpg, png, jpeg');
}
$imageName = $file->getClientOriginalName();
$file->move("user/img", $imageName);
$post->image = $imageName;
} else {
$imageName = null;
}
$post->save();
return back()->with('create_posts_success','Published!');
}

Answer 1

you must be saving filename in database somewhere for this uploaded post
now when you delete that post,
-> get the name of the file from your db record,
-> check if the file exists at the location using file_exists()
-> delete the found file using unlink()
-> get file deletion response (true|false)
in your case, it becomes something like below
$filePathName = 'user/img/' . $post->image;
if( file_exists($filePathName) ){
unlink($filePathName);
}
ignore my syntax mistakes please
