Custom validation rules? - El Forum - 01-19-2008
[eluser]RyanH[/eluser]
I'd like to create some custom validation rules, but I'm not sure how. The most important rule I want to create is to specify the email address. I want someone's email address to match only certain domains. For example, I only want email addresses that are coming from Gmail. [email protected] would work, but [email protected] would not. Any advice? Thanks.

Something like this might work:
Code:
$parts = explode("@", $email);
$domain = $parts[1];
//Check if $domain is in list of allowed domain - using an array here
if (! in_array($domain, $allowed_array))
//error
else

Code:
class MY_Validation extends CI_Validation
{
function domain_email($str,$params)
{
$parts = explode("@", $str);
$domain = $parts[1];
$allowed_array = explode(',',$params);
//Check if $domain is in list of allowed domain - using an array here
return in_array($domain, $allowed_array);
}
}Code:
$rules['email'] = 'valid_email|domain_email[gmail.com]';Custom validation rules? - El Forum - 01-19-2008

Hi RyanH,
If you don't prefer creating new class, you might create callback function in your controller - simply put xwero's domain_email function in your controller and use it in your rules in this manner:
Code:
$rules['email'] = 'valid_email|callback_domain_email[gmail.com]';Custom validation rules? - El Forum - 01-19-2008

Code:
$rules['email'] = 'valid_email|callback_domain_email[gmail.com]';Also, how do I go about creating a validation rule that allows spaces? I want to allow only alpha numeric, or just numeric, but also contain spaces. For example, a state name may have two words such as New York, but when you use the alpha or alpha_numeric rule, that returns false.
