Is there a file in codeIgniter in which I could just edit so that I can customize the form validation messages?
I just want to place them in a bulleted list to consume less space.
Here's the code that I'm using to output the error messages:
<div class="alert <?php echo $alert['alert_type']; ?> min-form">
<button type="button" class="close" data-dismiss="alert">x</button>
<h4><?php echo $alert['main_message']; ?></h4>
<?php echo $alert['sub_message']; ?>
</div>
Basically the $alert['sub_message']
is just getting its data from validation_errors()
function from CodeIgniter which outputs the validation errors from a form.
You can change the Error Delimiters in this way:
<ul>
<?php echo validation_errors('<li>', '</li>'); ?>
</ul>
docs: https://www.codeigniter.com/user_guide/libraries/form_validation.html#changing-the-error-delimiters
For v3: https://www.codeigniter.com/userguide3/libraries/form_validation.html#changing-the-error-delimiters
You can extend the form_validation class for maximum control by creating application/libraries/MY_form_validation.php
to add extra validation rules - I've attached an example below.
It is bad practice to edit system libraries directly; CI provides better options (overrides/customization thru MY_
classes, libraries, hooks, etc). This gives you the benefit of easily upgrading CI versions & keeps your application portable / custom code isolated from the core framework.
