PHP 7 Compatibility

I may be wrong, but I am testing this (line 81-83 – /wp-content/plugins/gravity-forms-constant-contact/api/cc_class.php) :

        protected function isValidEmail($email){
             return preg_match("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$/i", $email);
        }

Just wanted to follow up on the question of PHP7 compatibility…? Thanks!

Hi there,
Same question, same errors and warning as vijuston found using the WP Engine PHP Compatibility Checker. I’d love to keep using your plugin if possible.
Thank you.

In the meantime…
To make this version PHP7 Compatible, change line 82 of plugins/gravity-forms-constant-contact/api/cc_class.php from:
return eregi(“^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$”, $email);
to:
return preg_match(“^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$”, $email);

you missed the /i switch, so your example is case sensitive greg.

eregi is preg match with /i – though it seems like regex would be a more modern way.

From what I can tell, the function that contains the offending code – isValidEmail – is never actually used anywhere within the plugin.

Yes, isValidEmail isn’t used in the code. Version 3.0 should be PHP 7+ compatible.

is still an issue in 3.0

Oh, if the function isn’t used, it’s a false-positive. OK!
