Allowing apostrophes(') in a valid email address in codeIgniter

I have recently tried to validate the email of users using CI "Form_validation" Library and have found that using the valid_email it failed quite a few addresses that had apostrophe in their email address such as salman.D'Ahmad@example.com

I already added the apostrophe in there regular expression but still its not validate the email address with apostrophe(') .

Orignal Code:

public function valid_email($str)

{

         return ( ! preg_match("/^([a-z0-9\+_\-]+)(\.[a-z0-9\+_\-]+)*@([a-z0-9\-]+\.)+[a-z]                          {2,6}$/ix", $str)) ? FALSE : TRUE;

}







Solution : This is a very small change if you see first by just adding the apostrophe in regex expression but its not working like below :





Change Code:




public function valid_email($str)

{

       return ( ! preg_match("/^([a-z0-9\+_\-']+)(\.[a-z0-9\+_\-']+)*@([a-z0-9\-]+\.)+[a-z]                        {2,6}$/ix", $str)) ? FALSE : TRUE;

}

Final Solution:

public function valid_email($str)

{

$str = str_replace(''', "'", $str);

return ( ! preg_match("/^([A-Za-z0-9\+_\-']+)(\.[A-Za-z0-9\+_\-']+)*@([a-z0-9\-]+\.)+                   [a-z]{2,6}$/ix", $str)) ? FALSE : TRUE;

}

Happy coding :)
