I want to return the value entered by the user at the time of validation error - yoshi - 04-09-2022
## overview
where is 'set_fields'.
## reference
https://codeigniter4.github.io/userguide/libraries/validation.html
## detail
The Codeigniter 3 Tutorial had a special variable called 'set_fields'.
The effect was to display the 'post' data entered by the user.
Now, when I have a simple "create lesson" controller like this, is there a way to keep the values entered by the user?
or should I assign it to '$ _POST' and use 'post' in the template?
PHP Code:
/**
* @throws ReflectionException
*/
public function create(): RedirectResponse|string
{
$data = null;
if ($this->request->getMethod() === 'post') {
$this->validation->reset();
if ($this->validate(
[
'lesson_title' => ['label' => 'title', 'rules' => 'required'],
]
)) {
// valid
$isContinuous = $this->request->getPost('is_continuous');
if (isset($isContinuous)) {
return redirect('lesson_create');
} else {
return redirect('lesson_list');
}
} else {
// invalid
$data['validation'] = $this->validator;
view(route_to('lesson_create'), $data);
}
} else {
$data = [
'title' => null,
'body' => null,
];
}
$b = new Breadcrumb();
$b->add('Home', route_to('school_home'));
$b->add('lesson manage', route_to('lesson_list'));
$b->add('lesson create', null);
$data['breadcrumb'] = $b->render();
return view(route_to('lesson_create'), $data);
}

Do you mean set_value in CI3? If you validate via ajax you wouldn't have to repopulate the form.

thankyou for reply ignitedcms.
the following address is for reference. However, looking inside the `set_value`, it seems that using `$ _POST` after all.

The tutorial doesn't seem to use `ajax`, but I'd like to take a look at the `ajax` page and create a validation mechanism.

thanks kenjis
Oh? It seems that I misunderstood that 'set_value' was gone.
Thank you

I believe you were looking for 'set_fields' which is IIRC what it was historically named. Additionally in the old documentation there was a section under libraries > validation which discusses repopulating the form which appears to have been omitted, although as Kenjis has kindly pointed out is in the form helper section.
Off topic, I do prefer validating forms with ajax calling server side validation as it skips a step of having to manually repopulate input fields, though this is predicated on js being enabled in browser.

thanks, ignitedcms.
Yes. It was exactly the old `set_values` on the Validation page of the old document.
I would like to challenge later even if I use Ajax
