accept only english character in form validation in codeigniter

Question

I want to accept only English character in a text box form validation in codeigniter. Is there any built form validation method for this or should I use my own validation function for implementing this?

Answer 1

The rule you need is alpha. You could do something like this:

$this->form_validation->set_rules('text', 'Text','required|alpha');

To ensure that what is entered contains only alphabetical values.

See the rule reference on the codeigniter documentation.
