Title: .edu registration only Last modified: August 22, 2016 --- # .edu registration only * [marktvb](https://wordpress.org/support/users/marktvb/) * (@marktvb) * [11 years, 8 months ago](https://wordpress.org/support/topic/edu-registration-only/) * I would like to only allow registration on my site from .edu email addresses. I am getting a lot of spam registrations and I’ve tried a few plugins that can block specific domains, but I keep getting new ones. I tried a whitelist plugin, but it only allowed for whitelisting full domains (@harvard.edu for example instead of *.edu). Any ideas? Thanks!

Then the whole site stopped loading until I removed that snippet of code. Any ideas? * [KTS915](https://wordpress.org/support/users/kts915/) * (@kts915) * [11 years, 8 months ago](https://wordpress.org/support/topic/edu-registration-only/#post-5286663) * Just tried this myself, and I didn’t get an error. Are you sure you didn’t add it into another function in that file? * In other words, does the last `?>` actually indicate the end of the page, or just the end of the last function? (It isn’t necessary to have a `?>` to end the file. ) * So maybe try it again, but pasting what krumch has given you _after_ the last`? >`? * Thread Starter [marktvb](https://wordpress.org/support/users/marktvb/) * (@marktvb) * [11 years, 8 months ago](https://wordpress.org/support/topic/edu-registration-only/#post-5286686) * I tried adding it after the last ?> and it is now showing at the top of the page: [http://www.softwarephd.com/](http://www.softwarephd.com/) * Sorry, I’m not very familiar with custom coding.

I use bluehost which is a pretty standard hosting service. * [KTS915](https://wordpress.org/support/users/kts915/) * (@kts915) * [11 years, 8 months ago](https://wordpress.org/support/topic/edu-registration-only/#post-5286748) * Well, I don’t know what caused the response to krumch’s code. * But I realize we should have asked whether you are you using a WordPress registration form or an s2Member registration form. Neither code you’ve been given will work with s2Member’s registration form. * Thread Starter [marktvb](https://wordpress.org/support/users/marktvb/) * (@marktvb) * [11 years, 8 months ago](https://wordpress.org/support/topic/edu-registration-only/#post-5286773) * Yes, I’m using an s2Member reg form. * Thread Starter [marktvb](https://wordpress.org/support/users/marktvb/) * (@marktvb) * [11 years, 8 months ago](https://wordpress.org/support/topic/edu-registration-only/#post-5286774) * Yes, I’m using an s2Member reg form. * [krumch](https://wordpress.org/support/users/krumch/) * (@krumch) * [11 years, 8 months ago](https://wordpress.org/support/topic/edu-registration-only/#post-5286782) * [@marktvb](https://wordpress.org/support/users/marktvb/): This code should be in mu-plugins/s2-hacks.php file. To use it with s2M registration forms, you must find a good hook to run the function with. I search in s2M codes – always works for me. * Thread Starter [marktvb](https://wordpress.org/support/users/marktvb/) * (@marktvb) * [11 years, 8 months ago](https://wordpress.org/support/topic/edu-registration-only/#post-5286886) * Okay, can you explain that a little more. I’m not sure what exactly to do. What do you mean by a hook? * [KTS915](https://wordpress.org/support/users/kts915/) * (@kts915) * [11 years, 8 months ago](https://wordpress.org/support/topic/edu-registration-only/#post-5286898) * Perhaps you could try this in `mu-plugins/s2-hacks.php`: * ``` add_action('ws_plugin__s2member_after_register', 'validate_email_domain', 10, 3); function validate_email_domain( $errors, $login, $email ) { if ( is_email($email) and substr($email, -3) != 'edu' ) { $errors->add('email_domain', __('ERROR: You may only register with a .edu email address.')); } return $errors; } ``` * Let us know if it works! * [krumch](https://wordpress.org/support/users/krumch/) * (@krumch) * [11 years, 8 months ago](https://wordpress.org/support/topic/edu-registration-only/#post-5286904) * Sorry marktvb, somehow I missed your question. * Thanks KTS915 for answering 🙂 * Thread Starter [marktvb](https://wordpress.org/support/users/marktvb/) * (@marktvb) * [11 years, 7 months ago](https://wordpress.org/support/topic/edu-registration-only/#post-5286906) * I really appreciate your help. When I added that code to the s2-hacks.php file the code just showed up at the top of the site. [http://www.softwarephd.com](http://www.softwarephd.com) * Did I do something wrong?
