Can’t validate input

WordPress 4.9.4 running Mindstream Child Theme theme.
Running PHP version: 5.6.31-4+wpengine10

Hi – I’m demoing the free version of Mail Chimp for WordPress…hoping to get this working and then buy the full version.

there’s basically one thing I need it to do: collect emails and validate a predetermined code that the user needs to know in order to get a download.

I have added your validation code to functions.php and changed the necessary values to match my needs:

if( $_POST[‘CODE’] !== ‘GIMMEPOWER’ ) {

(full code at bottom of post)

With the code in functions.php, the validation code rejects all input whether or not it is correct.

I have also tried moving the code to the plugin editor you suggest (My Custom Functions), and also to the Body Scripts field of a page that references the shortcode for your form. In both of these cases, the validation code does nothing and allows all input.

—CODE:

/**
* Performs additional form validation on MailChimp for WP forms

*

* @return array An array of error codes.

*/

function myprefix_validate_mc4wp_form( $errors ) {

// perform validation here

if( $_POST[‘CODE’] !== ‘GIMMEPOWER’ ) {

$errors[] = ‘incorrect_value’;

}

return $errors;

}

add_filter( ‘mc4wp_form_errors’, ‘myprefix_validate_mc4wp_form’ );

/**

* Registers an additional MailChimp for WP error message

*

* @return array Array of messages

*/

function myprefix_add_mc4wp_error_message( $messages ) {

$messages[‘incorrect_value’] = ‘Please enter the correct value.’;

return $messages;

}

add_filter( ‘mc4wp_form_messages’, ‘myprefix_add_mc4wp_error_message’ );
