我正在执行更新方法。当我尝试更新特定数据时，我收到此错误“调用数组上的成员函数 save()”。为什么？我的代码中是否缺少某些内容？

我还尝试打印_r $result 变量，它有一个值..

Controller

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

    $result = $request->all();
    $test = $result->save();
    print_r($test);die;

    Session::flash('flash_message', 'Task successfully added!');

    return redirect()->back();
}

路线

Route::post('updateText/{id}','AdministratorController@updateText');

最佳答案

public function updateText(Request $request, $id)
{
    $result = YourModel::find($id);
    $result->your_column_1 = $request->your_value_1;
    $result->your_column_2 = $request->your_value_2;
    $result->your_column_3 = $request->your_value_3;
    $result->your_column_4 = $request->your_value_4;
    .
    .
    .
    $result->your_column_n = $request->your_value_n;

    if($result->save()){
        Session::flash('flash_message', 'Task successfully added!');
    }else{
        Session::flash('flash_message', 'Task failed!');
    }

    return redirect()->back();
}

这种方式可以帮到你。
