0 字段是必需的。 Laravel 5.5 验证错误

Question

我有一个“需要 0 字段”。当我没有名为 0 的字段时，尝试将数据保存到数据库时出错。没有来自控制器的验证，数据会保存，但如果我只验证要验证的六个字段中的一个字段，我仍然会收到错误消息。我该如何解决这个问题。请帮忙看看这是我的看法

                <button type="submit" class="btn btn-outline btn-primary pull-right">Submit</button>
                <br/>
              </form>

和我的控制器

public function store(Request $request)
{
    //validation
    $this->validate($request, array([
        'tenant_id' => 'required',
        'asset_id' => 'required',
        'description' => 'required',
        'address' => 'required',
        'price' => 'required',
        'occupation_date' => 'required',
    ]));

    //create and save new data
    $tenantProperty = New TenantProperty();
    $tenantProperty->tenant_id = $request->tenant_id;
    $tenantProperty->asset_id = $request->asset_id;
    $tenantProperty->description = $request->description;
    $tenantProperty->address = $request->address;
    $tenantProperty->price = $request->price;
    $tenantProperty->occupation_date = $request->occupation_date;
    $tenantProperty->save();
    //redirect
    return redirect('agent/tenantProperty_list');
}

路线如下

 Route::get('add_tenantProperty', 'TenantPropertyController@create')->name('/add_tenantProperty');
Route::post('add_tenantProperty', 'TenantPropertyController@store');

Answer 1

当您只写$request 时，它会传递整个请求对象，但验证函数希望两个参数都是数组。

所以做一点改变，你会很高兴的：

$this->validate($request, array(  // Removed `[]` from the array.
    'tenant_id' => 'required',
    'asset_id' => 'required',
    'description' => 'required',
    'address' => 'required',
    'price' => 'required',
    'occupation_date' => 'required',
));

Answer 2

上面的答案是正确的，这是我问的laravel 5.5上解决验证问题的另一种方法

$validation = validator::make($request->all(), [
        'tenant_id' => 'required',
        'asset_id' => 'required',
        'description' => 'required',
        'address' => 'required',
        'price' => 'required',
        'occupation_date' => 'required',
    ]);

Answer 3

 $request->validate([ 
'0'=>'',
'tenant_id' => 'required',
'asset_id' => 'required',
'description' => 'required',
'address' => 'required',
'price' => 'required',
'occupation_date' => 'required',]);
