Question

我在做更新方法。当我尝试更新特定数据时，即时收到此错误＆＃34;调用数组＆＃34;上的成员函数save（）。为什么？我的代码中是否缺少某些内容？

我也试过print_r $ result变量，它有一个值..

Answer 1

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。

Answer 2

要使用save()方法，您需要获取一个对象：

$result = Model::find($id);
$result->name = 'John';
$test = $result->save();

Answer 3

问：问。为什么返回此消息-> Call to a member function save() on array laravel 答：首先，您检查表中的$id值是否存在。

如果未在表中找到此主$id值，则返回此消息。

如果主要的$id值可用，则可以通过两种方式保存

    $data = Model::find($id);
    $data->name = 'Bulbul';
    $result = $data->save();
    //OR 
    $data = Model::find($id);
    $data['name'] = 'Bulbul';
    $result= $result->save();

在数组laravel上调用成员函数save（）
