英文:
There is a error in my form_validation in code igniter 3 it has a red line under it when i hover my mouse on in it says unindentified property
问题
我已经将它添加到我的自动加载
$autoload['libraries'] = array('form_validation', 'session', 'pagination');
$autoload['helper'] = array('url', 'form', 'text');
这是我将在我的表单验证上使用set_rules函数的控制器代码。
public function register()
{
$this->load->library('form_validation');
$this->form_validation->set_rules('first_name', 'First Name', 'trim|required|alpha');
}
尝试重新将form_validation添加到自动加载的库中
我真的不知道在这一点上该怎么办，目前是CodeIgniter的新手。
英文:
I already added it to my autoload
$autoload['libraries'] = array('form_validation','session', 'pagination');
$autoload['helper'] = array('url','form','text');
Here is the controller code where I am going to use the set_rules function on my form validation.
public function register()
{
$this->load->library('form_validation');
$this->form_validation->set_rules('first_name','First Name','trim|required|alpha');
}
tried re-adding the form_validation to the autoload libraries
I don't really know what to do at this point currently a newbie at using code igniter.

你之所以会收到该错误是因为你的控制器及其父类在其源代码中没有form_validation属性。
如果你查看CI_Controller（你的控制器应该是扩展自CI_Controller的）的源代码，你会发现这是正确的，但是CI_Controller也允许你通过其load属性加载库。
当你调用$this->load->library('form_validation')时，这将在脚本执行期间为你请求的库（在本例中为form_validation）在CI_Controller上动态创建一个新的属性，然后你可以使用它。
但由于这个属性是动态添加的，不在源代码中，你的代码编辑器无法知道它，会认为你犯了一个错误并给出错误提示。
所以在这种情况下，你可以忽略这个错误，你的代码应该可以正常工作！
英文:
You're getting that error because your controller and its parent classes do not have a form_validation property in their source code.
If you look at the source code for CI_Controller (your controller should be extending CI_Controller) you can see that this is true, but CI_Controller also allows you to load libraries via its load property.
When you call $this->load->library('form_validation') this then (during script execution) creates a new property on CI_Controller for the library you've requested (form_validation in this case), which you can then use.
But since this property is added dynamically and is not in the source code, your code editor can't know about it, thinks you're making a mistake and gives you the error.
So you can ignore the error in this case, your code should work!
