Laravel 5.6-从数据库JSON值获取第一密钥

Question

In DB I have saved value like this:

["IMG_4772.JPG","IMG_4775.JPG"]

In my view I'm trying to get first key like this:

background-image: url( {{ asset('img/ads/' . json_decode($ad->images, true)[0]) }} );

While inspecting element URL looks perfectly, as needed - /public/img/ads/IMG_4772.JPG . I'm also able to copy/paste/open this URL in my browser and see the pic.

But the console gives me an error GET /public/img/ads/IMG_4772.JPG 0 () and the pic is not displayed as background-image of the block. What is the problem?

Controller:

if ( $request->hasfile('images') ) {
    foreach ( $request->file('images' ) as $image) {
        $name = $image->getClientOriginalName();
        $image->move(public_path() . '/img/ads/', $name);
        $data[] = $name;
    }
}

$ad->images = json_encode($data);

Answer 1

尝试添加斜杠

background-image: url('{{ asset('img/ads/' . json_decode($ad->images, true)[0]) }}');
