在非对象上调用成员函数fill() [英] Call to a member function fill() on a non-object

问题描述

尝试将信息添加到空的profile并重定向回.

Trying to add information to an empty profile and redirect back.

$user = User::whereUsername($username)->firstOrFail(); // Selects correct user

$input = Input::all(); // a dd($input) at this point confirms input present

$this->profileForm->validate($input); // Passes

$user->profile->fill($input)->save();

return Redirect::route('profile.edit', $user->username);

如果$user->profile是null，则出现错误:Call to a member function fill() on a non-object.我试图用以下方法解决这个问题:

If $user->profile is null then this gives the error: Call to a member function fill() on a non-object. I tried to remedy this with:

$user = User::whereUsername($username)->firstOrFail(); // Selects correct user

$input = Input::all(); // a dd($input) at this point confirms input present

$this->profileForm->validate($input); // Passes

if ($user->profile == null)
{
    $user->profile = new Profile;
}

$user->profile->fill($input)->save();

return Redirect::route('profile.edit', $user->username);

但是在这种情况下，它无需添加配置文件详细信息即可重定向(此时$user->profile仍为null).

But in this case it is redirected without adding the profile details ($user->profile is still null at this point).

如果$ user-> profile文件已经包含信息，则不会出现此问题，并且代码可以正常工作.

If $user->profile already has information then this problem does not occur and the code works fine.

推荐答案

您可以这样做:

if (count($user->profile))
{   
    $user->profile->fill($input)->save();
}
else
{
    $profile = Profile::create($input);

    $user->profile()->save($profile);
}
