Question

我目前正在尝试将数据从数据表中保存回数据库。我正在处理数据表中的表单字段，并希望更改输入值并保存回数据库。理想情况下，我想要的是能够保存到数据库中的另一个表，如果id不存在但是现在我只是尝试进行更改并将其恢复到原始表。我正在使用laravel 5.4和datatables插件。我一直在寻找关于laracasts，堆栈溢出和数据表的各种帖子。我将我的数据保存在我的控制器中并继续获得一个对象作为回报。我已经尝试在我的模型中更改受保护的$ casts以查看我在开发工具中获得的值，但它没有帮助。我也在我的控制器中尝试了多种保存方法但没有用。请参阅下面的回复和代码：

路线：

Route::get('/plunker', ['uses'=>'Controller@plunker']);
Route::get('/plunker/ttotgetposts', ['as'=>'plunker.ttotgetposts','uses'=>'Controller@ttotGetPosts']);
Route::post('/plunker', 'Controller@saveOrUpdate')->name('saveOrUpdate');

型号：

namespace App;

use Illuminate\Database\Eloquent\Model;
use \DB;

class Inducted extends Model
{
    protected $casts = [
        'id' => 'string',
        'book_name' => 'string',
        'date_inducted' => 'string',
    ];
    protected $table = 'books';
    protected $fillable = ['book_id', 'book_name', 'date_inducted', 'updated_at', 'created_at'];

}

    public function plunker()

Answer 1

试试这个

public function saveOrUpdate(Request $request){
    // dd($request->all());
    $ids = $request->get('id');
    $names = $request->get('name');
    $inducteds = $request->get('inducted')

    foreach($ids as $id) {
        DB::table('books')->where('id','=', $id)
        ->update([
            'book_name' => $names[$id],
            'date_inducted' => $inducteds[$id]
        ]);
    }

    return redirect('/index')->with('status','Successfully updated !');
}
