display old value in form - muuucho - 03-11-2020
I follow the Blog example from the docs and I'd like to have my form display old value when validation fails.
Controller:
Code:
public function create()
{
helper('form');
$model = new NewsModel();
if (! $this->validate([
'title' => 'required|min_length[3]|max_length[255]',
'body' => 'required'
]))
{
if($_POST){
return redirect()->back()->withInput()->with('errors', $this->validator->getErrors());
}else{
echo view('templates/header', ['title' => 'Create a news item']);
echo view('news/create');
echo view('templates/footer');
}
}
else
{
$model->save([
'title' => $this->request->getVar('title'),
'slug' => url_title($this->request->getVar('title')),
'body' => $this->request->getVar('body'),
]);
echo view('news/success');
}
}PHP Code:
<h2><?= esc($title); ?></h2>
<?= \Config\Services::validation()->listErrors(); ?>
<form action="/news/create" method="post">
<label for="title">Title</label>
<input type="input" name="title" value="<?= old('title');?>" /><br />
<label for="body">Text</label>
<textarea name="body"></textarea><br />
<input type="submit" name="submit" value="Create news item" />
</form>

I' am taking this off the top of my head the way the forms are done in Myth/Auth.
I do recommend that you download it and view the controller and views with forms.
PHP Code:
$rules = [
'title' => 'required|min_length[3]|max_length[255]',
'body' => 'required'
];
if (! $this->validate($rules))
{
return redirect()->back()->withInput()->with('errors', $this->validator->getErrors());
}
Give that a try, I did not have time to test it but like I said Myth/Auth is a great learning module.
