设置验证消息

Question

I am trying to set a validation message for a set_rule....is this possible?

I tried this

$this->form_validation->set_rules('payment_amount', 'Payment Amount', 'regex_match[/^\d{0,4}(\.\d{1,2})?$/]');
$this->form_validation->set_message('payment_amount', 'This is a test');

and my message did not change.

Any ideas?

You can set a custom validation error message by creating a function for the rule.

This code is untested.

public function payment_amount($str)
{
    if (preg_match('[/^\d{0,4}(\.\d{1,2})?$/]', $str)
    {
        $this->form_validation->set_message('payment_amount', 'The %s field has an error');
        return FALSE;
    }
    else
    {
        return TRUE;
    }
}

Us CI's callback as follows:

$this->form_validation->set_rules('payment_amount', 'Payment Amount', 'callback_payment_amount')
