Email validation

[eluser]Madmartigan1[/eluser]
I think [email protected] is technically valid...?

Code:

/**
     * Valid Email
     *
     * @access    public
     * @param    string
     * @return    bool
     */
    function valid_email($str)
    {
        return ( ! preg_match("/^([a-z0-9\+_\-]+)(\.[a-z0-9\+_\-]+)*@([a-z0-9\-]+\.)+[a-z]{2,6}$/ix", $str)) ? FALSE : TRUE;
    }

You can create MY_Form_Validation.php and override the function there with your own. See the user guide section about extending libraries and have a look at system/libraries/Form_Validation.php
