how to prevent use of spam mails during registration

[fabricebartoli90]

Hi, i need to avoid users to signup with some mail service like yopmail.
How can i do it?

You need to add Disposable email check for that. There are free API’s like https://debounce.io/free-disposable-check-api/. It’s super simple as you only need to make a GET request with the user input email and the response JSON will tell you if it is disposable or not.

You can add this check using ‘wcfm_form_custom_validation’ filter.

sorry, i am not a developer, how can i use that filter? can you give me an example? thank you very much

ps. With that service, can i also prevent users to use my domain mail?

i would need just to set some domains to block, without an api service, and use this check in the wcfm and buddypress signup forms

If you don’t use any external API’s then you will need to add the restricted email domains manually. Following is a sample code to achieve what you want –

function custom_email_validation($wcfm_membership_registration_form_data, $form) {
    if($form=='vendor_registration') {
        $user_email = $wcfm_membership_registration_form_data['user_email'];
        $email_domain = substr($user_email, strpos($user_email, '@') + 1);
        $my_domain = str_replace('www.','',parse_url(get_site_url(),PHP_URL_HOST)); //Current website domain
        $restricted_domains = array($my_domain, 'yopmail.com', 'ymail365.com'); //add all the restricted email websites here
        foreach($restricted_domains as $domain) {
            if($domain == $email_domain) return array('has_error' => 'true', 'message' => 'Restricted email host used. Use a different one.');
        }
    }
    return $wcfm_membership_registration_form_data;
}
add_filter( 'wcfm_form_custom_validation', 'custom_email_validation', 10, 2);

Add this code to your child theme’s functions.php

In case you do not have child theme then add code using this plugin – https://wordpress.org/plugins/code-snippets/

i can’t do it for now, i have a lot of ticket not answered and i bought almost all your paid plugins.
Also is not possible to delete ticket already solved or which I no longer need, so is difficult to keeping track of those.

[Sushobhan]

Generally, we close a ticket once solved. We keep it open, till getting a confirmation from the user end. Though, sometime we may miss one or two.

Your customization email will get answered asap, right now we are taking a look at the plugin. Please confirm if you want to close this thread! Thanks!
