Custom form validation - chakycool - 01-24-2023

Hi All,
I has a custom form validation created just like the one on this tutorial (https://makitweb.com/create-custom-validation-rule-in-codeigniter-4/) and was working fine on 4.2.1.
I just updated the core to 4.3.1 and the form validation errors are not been displayed on the view. Validation work and I can catch the custom error msg on the controller but it's not working on the view. Basically I load the service on the view and print the error as per below. Any idea why this is not working on 4.3.1 ?

Code:
//load the service

$validation = \Config\Services::validation()

//print the error

echo $error = $validation->getError('email');

See https://codeigniter4.github.io/CodeIgniter4/installation/upgrade_430.html#redirect-withinput-and-validation-errors

Try:

PHP Code:
<?php $validation = \Config\Services::validation(); ?>
↓
<?php $validation = session()->get('validation'); ?>

Thanks Kenjis, I went with the below code on the view if someone else run in to this issue.

Code:
echo session('validation') ? session('validation')->getError('email') : '';

you can also go with the very sort method as below and not load the service on the view at all.

Code:
<?=validation_show_error('email') ?>
