如何在 laravel 中制作 mysql 的更新数据

Question

我正在尝试使用表单中的值进行更新并使用路由将其传递到更新控制器，没有给出错误，但为什么在我更新数据后没有任何反应？

表格：

<form action="/update" id="frm_edit" method="post" enctype="multipart/form-data">

路线：

Route::post('/update', 'EditManga@update'); //update route
Route::post('/admin_page/manga_list', 'Add_Manga_Controller@upload')->name('upload.image');
Route::get('/admin_page/manga_list','ShowData@Manga_list');

控制器：

public function update(Request $request){
        $this->validate($request, [
            'image' => 'required|image|mimes:jpg,png,jpeg'
        ]);

        //MENGAMBIL FILE IMAGE DARI FORM
        $kode_manga = $request->input('kdmanga');
        $judul = $request->input('jdmanga');
        $alternatif = $request->input('almanga');
        $author = $request->input('aumanga');
        $status = $request->status;
        $lastup = $request->input('lumanga');
        $genre = $request->input('grmanga');
        $lastc = $request->input('lcmanga');
        $sinopsis = $request->input('sinopsis');
        $file = $request->file('image');

        DB::table('add_manga')->where('kode_manga',$kode_manga)->update([
            'judul_manga' => $judul,
            'alt_title' => $alternatif,
            'author' => $author,
            'status' => $status,
            'uploaded' => $lastup,
            'genre' => $genre,
            'latest' => $lastc,
            'summary' => $sinopsis
        ]);
        return redirect('/admin_page/manga_list');
    }
}

有没有其他方法或者我的代码有问题？谢谢。

在你的场景中，另一个这样做：

  public function update(Request $request, $id)
  {


    $this->validate($request, [
        'image' => 'required|image|mimes:jpg,png,jpeg'
    ]);

    //MENGAMBIL FILE IMAGE DARI FORM
    $kode_manga = $request->input('kdmanga');

    //getting the target row to updae
    $addmanga = DB::table('add_manga')->select('*')
            ->where('kode_manga',$kode_manga)->get();

    $id = $addmanga->id; // getting the id of the target

    $add_manga = App\YOUR_MODEL_NAME::find($id);

    $add_manga->judul_manga = $request->input('jdmanga');
    $add_manga->alt_title = $request->input('almanga');
    $add_manga->author = $request->input('aumanga');
    $add_manga->status = $request->status;
    $add_manga->uploaded = $request->input('lumanga');
    $add_manga->genre = $request->input('grmanga');
    $add_manga->latest = $request->input('lcmanga');
    $add_manga->summary = $request->input('sinopsis');
    $add_manga->file = $request->file('image');

    $add_manga->save();

    return redirect('/admin_page/manga_list');
}

希望这对你有用！
