控制器

public function store(Request $request)
{
    $this->validate($request, [
        'title' => 'nullable',
        'description' => 'nullable',
        'awards_image.*' => 'image|nullable|max:1999'

        }
        $fileNameToStore = serialize($awards);
    } else {
        $fileNameToStore = 'noimage.jpg';
    }

    $awardsContent = new Award;
    $awardsContent->title = $request->input('title');
    $awardsContent->description = $request->input('description');
    $awardsContent->awards_image = $fileNameToStore;
    $awardsContent->save();

    return redirect('/admin/airlineplus/awards')->with('success', 'Content Created');
}

推荐答案

您的数据库当前不允许标题列为空.您可以将表中的该字段更改为可为空，或者如果请求中的值为空，则可以更新代码以使用空字符串.

Your database doesn't currently allow the title column to be null. You can either change that field in the table to be nullable, or you can update your code to use an empty string if the value from the request is null.

$awardsContent->title = $request->filled('title') ? $request->get('title') : '';
