如何在控制器层中使用get对象

Question

I have a function in controller to remove category and its image file. But i am not able to access the path property. I am getting this error Undefined property: Illuminate\Database\Eloquent\Collection::$path. It is returning path but i am unable to use it.

public function remove($id) {
    //$category = Category::find($id)->delete();

    $category_image = CategoryImage::where('category_id', '=', $id)->get(['path']);

    echo $category_image->path;


    //return back();
}

Answer 1

You can use first() if you need to get just one object:

$category_image = CategoryImage::where('category_id', '=', $id)->first();

if (!is_null($category_image)) { // Always check if object exists.
    echo $category_image->path;
}

When you're using get(), you're getting a collection. In this case you can iterate over the collection and get data from each object, or just use index:

$category_image[0]->path;
