Form Field Validation

Hey @agreda,

You can add a pattern to your field like so, just change the domain.com example to match the domain you wish to validate.

add_filter('yikes-mailchimp-field-data', 'add_pattern_to_mailchimp_emails', 10, 3);

function add_pattern_to_mailchimp_emails( $field_array, $field, $form_id  ) {
    if( isset( $field['merge'] ) && 'email' == $field['type'] ) {
        $field_array['pattern'] = 'pattern="[\w.%+-]+@domain\.com"';
    }
    return $field_array;
}

This could can be added to your functions.php file or by using a custom plugin. If you don’t know how to add this to your theme you’re probably better off adding it to a plugin.

Copy and paste the snippet from above into the custom PHP section of the plugin.

Let me know if you have any further questions or if this resolves your issue!

Cheers,

Freddie

PS: Here’s an example of changing the pattern for a website. Let’s say your website was “yikesplugins.com” you would change it to [\w.%+-]+@yikesplugins\.com

@agreda,

The example that I provided would be to limit the email submissions to a specific TLD but if you’d like to do it for the URL fields you would do it like so:

add_filter('yikes-mailchimp-field-data', 'add_pattern_to_mailchimp_urls', 10, 3);

function add_pattern_to_mailchimp_urls( $field_array, $field, $form_id  ) {
    if( isset( $field['merge'] ) && 'url' == $field['type'] ) {
        $field_array['pattern'] = 'pattern="^(http|https)?:\/\/([a-z0-9]+[.])?domain.com\/?$"';
    }
    return $field_array;
}

This will allow any subdomain as well as http or https for domain.com
