Error “Call to undefined method stdClass::delete()” while trying delete a row in Laravel

问题

My method to delete an image from database and local storage.

public function destroy($id) {
        $image = DB::table('images')->where('id', '=', $id)->first();
        //print_r($image);
        //return 'end';
        File::delete(public_path() . '/images/gallery/thumb-' . $image->path);
        File::delete(public_path() . '/images/gallery/' . $image->path);
        $image->delete();
        return Redirect::back()
                        ->with('form_success', 1)
                        ->with('form_message', 'Image successfully deleted!');
    }

If I try to return value of $image I get:

stdClass Object ( [id] => 49 [site_id] => 1 [page_id] => [location] => gallery [alt] => [path] => 60e52a2755ffe8923d5ac1232f5d9154.jpg )

So what's wrong with my code? Now my Laravel version is 4.2.1, but i try to downgrade him to 4.1.17, but no changes.

Change your code according the following and I hope that your problem will be solved..

public function destroy($id) {
        $query = DB::table('images')->where('id', '=', $id);
        $image = $query->first();
        //print_r($image);
        //return 'end';
        File::delete(public_path() . '/images/gallery/thumb-' . $image->path);
        File::delete(public_path() . '/images/gallery/' . $image->path);
        $query->delete();
        return Redirect::back()
                        ->with('form_success', 1)
                        ->with('form_message', 'Image successfully deleted!');
    }

first() and delete() these functions execute the code.So first assign your conditions to a variable and then execute them separately.Thanks

The problem is once you call first(), the query is executed and the results are returned. You will have to call delete() before you call first().

DB::table('images')->where('id', $id)->delete();

Since you are using the query builder, you are going to get back stdClass objects (which do not have delete methods) as you've seen rather than the models you'd usually get when using Eloquent.
