Problem with valid_email return true for invalid email address - zjonsnowz - 03-17-2018
Hello,
I'm new to CI and just setup and working on the sign up form, but some how the valid_email rule in form validation is not working. I have tried the function valid_email() too and it's still not working. How come this email "a!b#c$e%g^h&j*[email protected]" can pass the validation?
PHP Code:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Welcome extends CI_Controller
{
public function index()
{
$this->load->helper('email');
if(valid_email('a!b#c$e%g^h&j*[email protected]'))
{
echo 'valid email';
}
else
{
echo 'invalid email';
}
$this->load->view('welcome_message');
}
}
This code is displaying "valid email". Did I miss something? Please help.

Because it's valid (and don't know that gmail have restrictions):

So if I want to reject that email, then I guess I have to create my own rules.
Thanks jreklund.

You should be using the PHP Filters.
PHP Code:
$email = "[email protected]";
if (filter_var($email, FILTER_VALIDATE_EMAIL)) {
echo("$email is a valid email address");
} else {
echo("$email is not a valid email address");
}

That's correct. According to the standard it's valid, but I haven't seen any human include those signs... So you can also check for symbols and deny those e-email addresses.
@InsiteFX: That's exactly what that function does.

@pooja7r
Why did you post and repeat something that I had already posted?
