How to use regular expression with form_validation library

i want to add regular expression in $this->form_validation->set_rules() but unable to find any correct solution for that. as i want that my input field should only have 0 or 1 so how can i place inside setrules() like

$this->form_validation->set_rules('binary', 'Binary', 'required|regexp_match[*//code..]');

thanks in advance

The expression should be like:

/^[01]{1}$/           OR                 /^[01]$/

Which corresponds to:

  • Only 1 or 0

  • Only one symbol allowed

So (updated delimiters):

$this->form_validation->set_rules('binary', 'Binary', 'required|regex_match[/^[01]{1}$/]')
