CI4 session_write_close() when redirect - Capah.maga - 06-18-2021
I am using CI4 an just learning and never using CI before.
I got this error:
Code:
PHP Fatal error: Uncaught Exception: Serialization of 'Closure' is not allowed in [no active file]:0
Stack trace:
#0 [internal function]: session_write_close()
#1 {main}
thrown in [no active file] on line 0Here my Controller:
PHP Code:
public function create()
{
$data = [
'title' => 'Add new banner',
'validation' => \Config\Services::validation()
];
return view('admin/banners/add', $data);
}
public function save()
{
if (!$this->validate([
'banner_name' => 'required',
'banner_caption' => 'required',
'banner_details' => 'required',
'image' => 'required'
])) {
$validation = \Config\Services::validation(); // dumb here all data show
return redirect()->to('/banners/create')->withInput()->with('validation', $validation); // dumb in view cannot show data
}
$this->BannersModel->save(
[
'banner_name' => $this->request->getVar('banner_name'),
'banner_caption' => $this->request->getVar('banner_caption'),
'banner_details' => $this->request->getVar('banner_details'),
'image' => $this->request->getVar('image'),
'publish' => 1
]
);
session()->setFlashdata('message', 'Data Saved');
return redirect()->to('/banners');
}
I already try dumb $Validation before
PHP Code:
dd( $validation = \Config\Services::validation());
when dumb show all the value.
But after redirect there are no value error in validation and i got that error.
what that i do wrong?
best regards,

RE: CI4 session_write_close() when redirect - includebeer - 06-18-2021
PHP Code:
->with('validation', $validation)
You can't save $validation in the session like that. It's an instance of the validation library, that's why it crashes in session_write_close().
Here is an example to send the error messages to the redirected page. Use validate() to validate the rules, then use validator to get the error messages.
You can see a detailed example in this tutorial: https://includebeer.com/en/blog/how-to-build-a-basic-web-application-with-codeigniter-4-part-6
PHP Code:
if ( ! $this->validate($rules))
{
return redirect()->back()->withInput()->with('errors', $this->validator->getErrors());
}
