Answer 1

Not tested, but I think something like this should work fine.

$image_path = "/images/";  // Value is not URL but directory file path
Post::where(['id'=> $id])
        ->where(function($query){

             if(File::exists($image_path . $post_image)) {
                 File::delete($image_path . $post_image);
             }
              $query->where('post_image', $post_image)
          })
         ->delete();

Answer 2

In general, the path issue should probably be absolute.

See How to delete file from public folder in laravel 5.1 I don't know in Laravel 6, but it should work.

ie using File :: delete ()

Answer 3

Add the folder that contains your image to your config/filesystems.php files:

'disks' => [

    'local' => [
        'driver' => 'local',
        'root' => base_path('app'),
    ],
    //Above bit should already be there. So add this....  

    'some-image-path' => [
        'driver' => 'local',
        'root' => base_path("wherever/your/directory/is/from/root/"),
    ],

You would then use it like this:

  $myImage = 'some-image.png'; 
  Storage::disk('some-image-path')->delete($myImage);

public function multipleUserDelete(Request $request,$id, $post_image){

    if ($request->isMethod("post")) {
        $data=$request->all();   

        $postDeletes=Post::where(['id'=> $id])
                            ->where('post_image', $post_image)
                            ->get();
        $img_array = array();
        foreach ($postDeletes as $postDelete) {
            $large_image_paths='images/backend_image/admin_users/small/';

            $medium_image_paths='images/backend_image/admin_users/medium/';

            $small_image_paths='images/backend_image/admin_users/large/';
            $img='';
            if(file_exists(public_path($large_image_paths. $postDelete->post_image))){
                $img = $large_image_paths. $postDelete->post_image;
            }

            if(file_exists(public_path($small_image_paths. $postDelete->post_image))){
                $img = $small_image_paths. $postDelete->post_image;
            }

            if(file_exists(public_path($medium_image_paths. $postDelete->post_image))){
                $img = $medium_image_paths. $postDelete->post_image;
            }

            array_push($img_array,$img);
        }

        \File::delete($img_array);
        Post::whereIn('id', $data['del_user'])->delete();

        return redirect()->back()->with("flash_message_success","you Successfully Deleted The Selected Users(s)");
    }
