In CodeIgniter, you can show error messages by using the set_flashdata() method in the controller and then accessing the flashdata in the view to display the error message. Here's an example of how you can show an error message in CodeIgniter:

1. In the controller, set the error message using set_flashdata() method:

1

$this->session->set_flashdata('error', 'An error occurred. Please try again.');

1. In the view, check if the flashdata exists and display the error message:

1
2
3
4
5

<?php if ($this->session->flashdata('error')): ?>
    <div class="alert alert-danger">
        <?php echo $this->session->flashdata('error'); ?>
    </div>
<?php endif; ?>

By following these steps, you can easily display error messages in CodeIgniter.
