In Codeigniter, you can get validation errors by using the form_validation library. Here is an example of how to get validation errors in Codeigniter:
- Load the Form Validation library in your controller:
1
|
$this->load->library('form_validation');
|
- Set the validation rules for your form fields in the controller method:
1 2 |
$this->form_validation->set_rules('username', 'Username', 'required');
$this->form_validation->set_rules('password', 'Password', 'required');
|
- Run the form validation in your controller method and check if it fails:
1 2 3 4 5 6 |
if ($this->form_validation->run() == FALSE) {
$data['errors'] = validation_errors();
$this->load->view('your_view', $data);
} else {
// Form validation passed, process the form data
}
|
- Display the validation errors in your view:
1 2 3 4 5 |
<?php
if(isset($errors)) {
echo '<div class="error">' . $errors . '</div>';
}
?>
|
By following these steps, you can easily get validation errors in Codeigniter.
