Pre format rules ignored - CI4 Validation

Hi Team,

If I apply any rule to CI4 Validation that returns string instead of boolean, that rule is skipped. No effect on data output / formatting.

Like this.

PHP Code:

$validation->setRules([
    'username' => 'trim|required',
    'password' => 'required|min_length[10]'
]); 


PHP Code:

$request->getPostGet('username'); // Username is not trimmed. 


This used to be working fine in CI3. How can I attain the same in CI4?

You need to run it through the validation.

I did create rules that has 'trim' rule,
Run the validation and I got true.
Input had spaces: '   sammiel    ';
I was hoping that after running the validation, I would get output without spaces. But the output had spaces as well - the reason why I posted my question in these forums.

Then you may have found a bug so report it on GitHub issues.

Why dont using alpha rule?

Can you show the whole code where you validate the username?
